There is an island, a four seasons like spring island, in Southeast Asia,
Its name is Taiwan.
Today might be the birthday of Taiwan since 60 years ago returned from Japan.
It's a lucky day for nationals can get their own rights in democratic way.
As i know Taiwan is a beautiful place with beautiful mountains and no pollutant bays.There are many kinds of delicious fruits, the snacks,and Chinese food make your body feel good. Also people here are beautiful ladies and gentlemen.The warm people live together which you might never discover in the map.
It's my honor to introduce Taiwan to all my Flickr friends and passer.
You all will love it.
Welcome to Taiwan

"Human activity such as pollutants can also enhance the colors at sunrise and sunset. Larger amount of pollution higher up in the atmosphere increases the amount of scattering of particles. Other weather phenomena, such as Saharan dust, volcanic chemicals, and wildfire smoke, also increase the number of particles available in the atmosphere. Similar to pollutants, the increase in particles can provide increased chances of scattering which could lead to more vivid sunrise and sunsets."
Many insects including butterflies have been suffering because of air pollutants, and by extension we also we suffer this effect. We will be in big trouble without the pollinators that distribute the polen to plants to form seeds and fruit.
If you want to know more about butterflies, how to help them, and more interesting stuff, visit this site is very good:

Photography is my passion, and nature photography is my favorite.
I have been in Explore for more that a hundred times, and it is an awesome experience to have your photos showcased in such a special way.
I'm in many groups, and I only add my photos to them if they are not private.
I thank your for coming today, for leaving a comment, and make a favorite of yours this photo, (if that is the case) thanks again!
The best part of this forum is the contacts and friends that I have made over the years, that have the same passion for this art that is called photography!
Martha,
The rural countryside of Vermont comes alive in the spring with every possible vibrant shade of green. This scene could be a cover to the book, Silent Spring by Rachel Carson. She attempts to educate people on the long devastating effects of pollutants and insecticides on nature.. With the new Spring growth comes a new spirit of optimism that the human race will wake up to the dangers
Thank you for taking the time to view my photos. They can be purchased at www.naturalworldfotos.com
When sugarcane is burned to remove the outer leaves around the stems before harvesting, thousands of tons of dangerous pollutants are released into the air in March and April. Evening sun to smog and haze in Sukhothai, Thailand
As most landscape photographers know, it can serve the image well to capture color after a rainstorm. The air is devoid of debris like pollutants. foliage is wet and vividly saturated with color, and a polarizing filter helps too. This hiking trail helps illustrate that point, having photographed it a few hours after a down pour.

Svalbard, Norway
From Wikipedia:
"The Svalbard reindeer (Rangifer tarandus platyrhynchus) is a small subspecies or species of reindeer found on the Svalbard archipelago of Norway. Males average 65–90 kg (143–198 lb) in weight, females 53–70 kg (117–154 lb), while for other reindeer generally body mass is 159–182 kg (351–401 lb) for males and 80–120 kg (180–260 lb) for females
The species is endemic to the islands of Svalbard, where it has lived for at least 5,000 years and has become well adapted to the harsh climate, being found on nearly all non-glaciated areas of the archipelago. By 1925 they had almost gone extinct due to over-hunting in the late 19th and early 20th centuries. Over recent decades, their population has increased. As of 2019, the total population across the archipelago is approximately 22,000. They are the only large grazing mammal in the European High Arctic, and this makes them exceptional for studies concerning the introduction of pollutants to changing ecosystems. During the short Arctic summer, Svalbard reindeer feed on a lush tundra vegetation of vascular plants, including grasses, herbs, sedges and deciduous shrubs in the lowland plains and valleys, to accumulate fat for the winter. The fur of Svalbard reindeer contains elements and chemicals picked up from the vegetation they digest. They are relatively sedentary, and are thus highly vulnerable to changes in local conditions.
Compared to other reindeer, they are short-legged and have a small, rounded head. Their fur is also lighter in color and thicker during winter. The thickness of the coat contributes to the short-legged appearance and makes even starved animals appear fat in the winter. The males develop large antlers during the period from April to July and shed the velvet during August–September. Males lose their antlers in early winter. Females develop antlers starting in June and they are usually retained for a whole year. "

I have been waiting all summer for a view much like this. Clean views, a lovely fade into the blue haze over the mountains in a deep, wild valley. The sunset didn’t go quite the way I wanted, though the weather hardly ever cooperates with you. In the end, I opted for this deep dark valley shot on the last day of summer, right after a large storm had rolled through. The air cleaned of pollutants that often make up the unrelenting haze, giving way to the natural mist produced by the forests. I panicked getting to the location, panicked getting the composition, and I panicked getting the shot. In the end, after leaving the scene, wondering if I had managed to get my photo, I think I did alright.

Tiny leaf from a Katsura tree. Yes, we planted it when we moved here before questioning if native. But it does absorb air pollutants, perhaps. And the tree nursery sold and planted it along with many native cedars and sequoias.
A fern (Polypodiopsida or Polypodiophyta /ˌpɒliˌpɒdiˈɒfɪtə, -əˈfaɪtə/)[citation needed] is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.
Ferns first appear in the fossil record about 360 million years ago in the late Devonian period, but many of the current families and species did not appear until roughly 145 million years ago in the early Cretaceous, after flowering plants came to dominate many environments. The fern Osmunda claytoniana is a paramount example of evolutionary stasis; paleontological evidence indicates it has remained unchanged, even at the level of fossilized nuclei and chromosomes, for at least 180 million years.
Ferns are not of major economic importance, but some are used for food, medicine, as biofertilizer, as ornamental plants, and for remediating contaminated soil. They have been the subject of research for their ability to remove some chemical pollutants from the atmosphere. Some fern species, such as bracken (Pteridium aquilinum) and water fern (Azolla filiculoides) are significant weeds worldwide. Some fern genera, such as Azolla, can fix nitrogen and make a significant input to the nitrogen nutrition of rice paddies. They also play certain roles in folklore.
Es ist nicht gut bestellt um den deutschen Wald. Trockenheit, Hitze, Schädlinge und Schadstoffe setzen den Bäumen in Deutschland immer stärker zu. Demnach zeigen vier von fünf Bäumen Schäden, jeder dritte Baum hat eine deutlich ausgedünnte Krone. Zudem sind so viele Bäume abgestorben wie seit gut 20 Jahren nicht mehr.
Eine der Hauptursachen für den schlechten Zustand der deutschen Wälder ist das Klima: weil es in den letzten Jahren viel zu trocken und warm war, leiden die Bäume an Wassermangel. Das schränkt ihr Wachstum ein, fördert Waldbrände und macht sie Schädlingen gegenüber anfälliger. Zusätzlich gelten auch hohe Einträge von Luftschadstoffen wie Stickoxiden als potenziell waldschädigend. Der Wald ist durch Dürre, intensive Forstwirtschaft und Stickstoffeinträge im Dauerstress.
Things are not going well for the German forest. Drought, heat, pests and pollutants are increasingly affecting the trees in Germany. According to reports, four out of five trees show damage, every third tree has a clearly thinned crown. In addition, more trees have died than at any time in the last 20 years.
One of the main causes for the poor condition of German forests is the climate: because it has been far too dry and warm in recent years, the trees suffer from a lack of water. This restricts their growth, promotes forest fires and makes them more susceptible to pests. In addition, high inputs of air pollutants such as nitrogen oxides are also considered potentially damaging to forests. The forest is under permanent stress due to drought, intensive forestry and nitrogen inputs.
Lake Naivasha in Kenya is host to one of the most surreal landscapes I have seen in the world. There is some water in the lake, but for the most part it looks like it has been drained.
Some say that the flower industry that can be seen around the lake is to blame. Kenya provides cut flowers for Europe. the fields of flowers are impressive but apparently they are siphoning water from the lake and pollutants are being added to the water. Some say that excess water is causing the water to kill off the trees which surround the lake. The lake is not navigable at the present time.
I like the lines on this. I sometimes have to move these totes and they are filled with liquid, which makes them swish around on the forklift.
Happy Slider Sunday
Platanus × acerifolia, Platanus × hispanica, or hybrid plane, is a tree in the genus Platanus. It is often known by the synonym London plane, or London planetree. It is usually thought to be a hybrid of Platanus orientalis (oriental plane) and Platanus occidentalis (American sycamore). Some authorities think that it may be a cultivar of P. orientalis.[citation needed]
The London plane is a large deciduous tree growing 20–30 m (65–100 ft), exceptionally over 40 m (130 ft) tall, with a trunk up to 3 m (10 ft) or more in circumference. The leaves are thick and stiff-textured, broad, palmately lobed, superficially maple-like, the leaf blade 10–20 cm (4–8 in) long and 12–25 cm (5–10 in) broad, with a petiole 3–10 cm (1–4 in) long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are hairless or nearly so. The flowers are borne in one to three (most often two) dense spherical inflorescences on a pendulous stem, with male and female flowers on separate stems.
The fruit matures in about 6 months, to 2–3 centimetres (0.8–1.2 in) diameter, and comprises a dense spherical cluster of achenes with numerous stiff hairs which aid wind dispersal; the cluster breaks up slowly over the winter to release the numerous 2–3 mm (0.08–0.12 in) seeds. The London Plane is one of the most efficient trees in removing small particulate pollutants in urban areas.
It shares many visual similarities with Platanus occidentalis (American sycamore), from which it is derived; however, the two species are relatively easy to distinguish, considering the London plane is almost exclusively planted in urban habitats, while P. occidentalis is most commonly found growing in lowlands and alluvial soils along streams.
The Nile River, meandering from southern Egypt to the Mediterranean, has sustained the nearly 90 million people it serves. However, pollution is turning this vital waterway into a source of death and disease. The Egyptian Organisation for Human Rights reports that around 4.5 million tons of pollutants—including untreated or partially treated industrial waste, agricultural runoff, and sewage—contaminate the Nile annually. Nearly half of Egypt's population drinks water that is polluted or unfit for consumption.

This week David (www.flickr.com/photos/108755156@N05/) chose the theme Connections.
No matter how often I pass by these ancient River Red Gums on my daily walks, I am in awe. As I stood to look at this one, I saw at least 8 species of birds perch on the tree, several with nests. They are old enough to form hollows that are used by birds, bats and possums.
The willowing branches provide shelter and shade. They give us food and materials used today and by ancient peoples to sustain life.
Below ground the tree’s roots stabilise and aerate the soil, provide food for the soil fauna, fungi and bacteria. The bark, leaves and flowers of the tree support thousands of invertebrates.
The tree provides us with oxygen and stores carbon, filters out pollutant gases and give us clean air to help our planet survive.
They talk to each other and to us if we are willing to listen.
They have powers to heal.
So many connections are made by this single tree to create an entire ecosystem and some of the most vital connections to the well-being of the planet and its inhabitants.
Amethyst Deceiver (Laccaria amethystina)
This purple beauty is found in deciduous and coniferous forests in temperate zones around North America, Central and South America, Europe, and Asia. Though vividly purple when young, older specimens loose their bright coloration and are more difficult to identify, which is why it is called the "deceiver". Though technically edible, it isn't considered a good choice to eat especially because pollutants in the soil, such as arsenic, can bioaccumulate in the mushroom.

A wetland is land where water is above, at or near the surface near most years. These are transitional areas between terrestrial and aquatic swamps, sloughs and ponds, unvegetated flats and bogs. All these types of wetlands, with the exception of bogs, are found in the Everglades.
Wetlands are essential to human well-being as they allow water to seep into underground aquifiers which provide the fresh drinking water we need. Wetlands help prevent flooding and erosion by slowing surface run-off while acting as a natural treatment plant to filter pollutants in the water supply. They also provide shelter and food for many insects, birds, fish and other animals. Two-thirds of all threatened and endangered wildlife species in the United States live in a wetland eco-system. Wetlands are crucial for migratory birds too.
The winter Salt Lake inversion is not fun. The inversion traps cold air under warm upper air and traps pollutants in the valley.
On this sunset, the sky was excellent, but the low-level dark band is inversion pollutants. The mountains are ~7 miles (11 km) and hardly visible.
GPS is not the exact spot of the shot.

Why don’t you see them more often? The black-crowned night heron mainly feeds after dark. You are most likely to spot them at dusk and dawn along the edge of a waterway.
The black-crowned night heron was among many species declining nationwide between the 1940s and 1970s due to the cumulative effects of DDT and similar pesticides. Those environmental toxins were banned in the early 1970s.
While no longer considered at risk of a declining population, these herons are still affected by the accumulation of pollutants in the shellfish and fish they eat.
They are, however, one of the most wide-ranging of herons across North America. It is the larger of the two night heron species found in Florida.
With rare exceptions, the black-crowned night herons usually hover close to the water’s edge.
They commonly can be seen on mangrove roots, walking carefully along the edge of mud flats, and picking their way through cypress strands.
While they can be seen year-round in Florida, they can be found as far west as the Cascade Mountains of Oregon and Washington. They seasonally range into the central Canadian provinces and up the east coast all the way to Maine.
They feed in wetlands – freshwater, saltwater, and brackish – so that is the most likely place to find them.
I found this one just after sunrise along Peavine Road in Osceola County, Florida.

*As some of the most iconic fish species, is critically endangered. Because Groupers sit so high n the food chain, they are more likely to consume smaller fish that have ingested pollutants including plastics.

This was the view I had at a recent sewing retreat. The largest bump on the horizon is Denali (Mt. McKinley) and all the other squares on the horizon are mountains also. Clouds made them look like blocks. We had an inversion - warm air trapped cold air and kept the cold air (and all the pollutants) below. The higher up you go, the warmer it is. Since I was on Mt. Aurora, it was more than 30 degrees warmer than town.
I joined in the climate Change March in Cardiff yesterday. It was not only inspirational and moving to see the involvement of so many young people, but also to see this echoed all around the world. The best words in the speeches were always from the mouths of the young, a their care for the environment and the situation really shone through. I think as Landscape and nature photographers we are as aware as anyone of the damage we are doing to our environment. My coastal shots usually mask the increasing volumes of plastic and pollutants , and it gets harder and harder to take sky shots without the increasing contrails from planes polluting the atmosphere. I really hope something can be done to reverse this trend before time does run out for future generations to enjoy what we have had the privilege to.

As plastic is composed of major toxic pollutants, it has the potential to cause great harm to the environment in the form of air, water and land pollution
As romantic as this picture may seem at first glance, it is an illusion.
This unique blue atmosphere is a mixture of ordinary morning fog and the smoke that prevailed in the wilderness due to the many fires in large parts of Canada. The amount of smoke is so enormous that it is regularly blown hundreds of kilometers away. This is accompanied by a noticeable strain on the respiratory tract for every living creature. The air pollutants are too high. Both PM10 and the finer PM 2.5 particles represent a major burden in terms of the intensity measured. Both the PM10 and finer PM2.5 particles pose a significant burden at the measured intensity. Due to the massive fires, I am left with only two options: first, to adjust and change my travel route, and second, to capture these threatening scenarios in pictures.
Wetlands are a distinct ecosystem that benefit people through ecosystem services that include water purification, groundwater replenishment, stabilization of shorelines and storm protection, water storage and flood control, processing of carbon (carbon fixation, decomposition and sequestration), other nutrients and pollutants, and support of plants and animals. Put bluntly, no wetlands, no sustainable life for humans.

As the gull flies by. A wonder it's venturing so closely. The air pollutants are considered in range but long term effects from the fossil fuel industry must be at least questionable.
Mandarin Duck / aix galericulata. Attenborough, Nottinghamshire. 14/12/15.
A dull afternoon, a smart little duck!
I am intriqued by the patchy, almost iridescent colours on top of the beak. It has the quality of an oil slick and indeed, I am wondering if it is a residue from pollutants? Any opinions would be welcomed.
This image of a Southern California sunrise is an example of Rayleigh Scattering , which I described in a previous post of an Alberta, Canada mountain sunrise (for those interested, see below).
The brightly coloured skies we may see at sunrises and sunsets are due to a phenomenon called Rayleigh Scattering. It is named after the British physicist Lord Rayleigh who discovered it.
During sunsets and sunrises, when the sun is closer to the horizon, sunlight has to travel through a longer distance and more of the dense environment to reach an observer’s eye. Due to Rayleigh Scattering, most of the light of shorter wavelengths – the blue, violet, and green – are scattered away multiple times, leaving only lights of longer wavelength – the red, orange, and yellow – to pass straight through to the observer.
This is why a rising and setting sun tends to generate spectacular hues of red, orange, and yellow.
The quality of the air that sunlight has to pass through also has an effect on the color of sunrises and sunsets. Dust particles and pollutants tend to tone down the colors in the sky as well as impede light from reaching the observer on the ground. Because of this, the sky takes on dull hues of red and yellow when the air is full of dust and pollutants. This is why sunrises and sunsets in rural areas, over the ocean, and deserts are much more vibrant and colorful than over cities and urban areas.
Moss plays an important role in forest ecosystems, both in terms of its ecological function and its aesthetic appeal.
Ecologically, moss helps to regulate water levels in the forest by absorbing and holding onto moisture, preventing soil erosion, and providing a habitat for other organisms. Moss also acts as a natural filter, helping to purify water and absorb pollutants.
Aesthetically, moss is often considered lovely in a forest setting because of its lush green color and soft, velvety texture. It can create a peaceful, serene atmosphere, particularly when growing on rocks, fallen logs, or the forest floor. The slow growth and longevity of moss also add to its beauty, as it can take years or even centuries to develop into a mature clump.
Moss in a forest setting can also have cultural significance. In many cultures, moss is associated with tranquility, longevity, and harmony with nature. It is often used in traditional art forms, such as Japanese gardening and Scandinavian moss art, as well as in modern art installations and nature-based design.
This is not HDR.
What are the things you can see here??
This setting is as seen in the China Yuan.
When I saw the view, the color in my mind is this.

I am told that once the Da Ba The greatest dam completed, the ChongKing & Sichuan
area would become sub-tropical climate. They can grow Long Gun, LyChee....
If the Da Ba give way due to act of God, then the whole Shanghai would be about 200meters
under water.
The west coast of USA & Canada would have tsunami & also earthquake & some part of California
& Oregon would be sank under water as well.

trees fight climate change
so let us all start protect them instead of destroying our woodlands.
fifth fact: trees purify air: trees absorb pollutant gases such as nitrogen oxides, ozone, ammonia, sulfur dioxide. they also absorb odors and act as a filter as little particulates get trapped in leaves. a mature acre of trees can yearly provide oxygen for 18 people.

A retention pond in the background. This is the site of an old land fill (tip or dump in other countries). A mountain of trash which is covered over with dirt and grassed. I believe the pond is to retain run-off water which may contain pollutants. I have no desire to "trespass".

Sunset - Mojave Desert, Southern California.
This is a view of the sunset facing due east. How can the eastern sky be pink and red at sunset?
For just a few minutes after sunset, the eastern sky can be illuminated by small particles in the air, such as fog, air pollutants and smoke. As the sun drops below the horizon in the west, the sun’s reddish and pinkish light hits these particles high in the atmosphere causing the color in the east. This colorful evening sky is called the Belt of Venus. The dark layer below the pink is caused by the Earth’s shadow.
A bumblebee (Bomus sp) pokes individual flowers on the floral cylinder of a cutleaf coneflower (Rudbeckia laciniata), a particular favorite of bumblebees. Cutleaf coneflower are native to much of the U.S. and southern Canada. Its leaves are sensitive to ozone (a common air pollutant), and are used as indicators of ozone levels.
Same adult bird as previous photo.
The Lammergeier lives for around 30 years.
At 6 years old, its annual mortality rate is approximately 5 %. The adult birds begin breeding only at the age of 8 years, producing on average one fledgling every 3 years. The growth in numbers of the population is therefore extremely slow. Even a slight increase in death rate or disturbance to success in breeding can drastically affect the development of the population.
Unfortunately, there are many risks for the Bearded vulture, associated with its life in the mountains :
collision with overhead cables
poisoning and intoxication by contamination and pollutants which accumulate in the food chain
interference with reproduction from human activities, such as general aviation and free flying, outdoor and mountain sports.
By the beginning of the twentieth century the Bearded Vulture was totally extinct in the Alps. Although there is room for some optimism, it remains one of the most endangered species in Europe. After thirty years of programmes of reintroduction throughout the alpine region, in 2014 only 23 couples reproduced successfully, 9 of them in France. For this reason, the Bearded Vulture is the subject of a National Action Plan (PNA - Plan National d'Actions in France), which guides the restoration and conservation of the species.
*Thank you all so much for your kind comments and Favs. It’s most appreciated!
The idea here is to dam the Chicago River, tear out the locks, and allow the river to again flow into Lake Michigan, allowing nature as depicted above to cleanse the river of pollutants. Better upstream treatment might also be a component of such a plan.
Alleen bieten viele Vorzüge. So schützen sie vor Sonne oder Wind, und damit auch vor dem Humusabtrag in der Landwirtschaft. Sie verbessern bei Nebel und Dämmerung die Orientierung und erleichtern das Schätzen von Entfernungen. Das Wurzelwerk der Alleebäume festigt die Fahrbahnen und schützt die Wege auch vor Erosion und Verschlammung. Im Winter ist an den Alleebäumen der Straßenverlauf zu erkennen, die Bäume schützen auch vor Verwehungen. Wurzeln und Baumkronen reinigen zudem das Grundwasser, filtern vor allem Feinstaub und andere Schadstoffe aus der Luft. Der dichte Baumbestand in Alleen ist letztlich auch ein natürlicher Schallschutz.
Avenues offer many advantages. In this way they protect against sun or wind and thus also against humus degradation in agriculture. They improve orientation in fog and twilight and make it easier to estimate distances. The roots of the avenue trees strengthen the roadways and also protect the paths from erosion and silting. In winter the course of the road can be recognized by the avenue trees, the trees also protect against drifts. Roots and tree tops also clean the groundwater and filter fine dust and other pollutants from the air. The dense tree population in avenues is ultimately also a natural sound protection.
It is without a doubt that we have had more worldwide land destructions from storms of all kinds this year and yet we seem to put them behind us as if they do not exist! The pain experienced by so many could have been avoided so why won't we listen and do something about it? If we don't act soon we will have no world left to live in!
With heartfelt and genuine thanks for your kind visit. Have a wonderful and beautiful day, be well, keep your eyes open, appreciate the beauty surrounding you, enjoy creating and stay safe! ❤️❤️❤️
I was fortunate in being able to photograph this sky. The reddening of the clouds came on suddenly. Fortunately my camera was close at hand, because within ten minutes or so, the red colours had disappeared completely. What was going on?

I photographed this Old Man's Beard lichen while hiking in a rainforest near the town of Sechelt, in the Sunshine Coast region of British Columbia, Canada. Illumination oif the plant was through a ray of sunshine filtered by forest canopy.
Old Man's Beard Lichens (genus Usnea) are yellow or greenish bushy, branched lichens with long stems and disk-shaped holdfasts. They resemble tangled masses of threads.
This lichen is widely distributed, from the arctic to the tropics, and provides food for various wild animals. In the past, they were used as a remedy for whooping cough, catarrh, epilepsy, and dropsy, and they have been used also as an astringent, a tonic, and a diuretic. Some species of Usnea also produce an orange dye.
Beard lichens are sometimes confused with the plant known as Spanish moss (Tillandsia usneoides), which is similar in appearance but is unrelated to lichens.
Old Man's Beard Lichen is very sensitive to air pollutants such as sulphur dioxide, and as consequence is considered to be an indicator of poor air quality.
Excerpt from conservationhamilton.ca:
Meadows: Even though you don’t see any water here, this meadow is a very important part of the water system.
Meadows act as a kind of filter, regulating the movement of water into streams and aquifers. Rain water and storm run-off slowly percolate through the soil, eventually reaching a stream bed or aquifer.
The soil also helps to filter pollutants from the storm run-off water. Contaminants like litter, animal scat, and oil are trapped in the soil and kept from entering the water table.
I love the fragile filaments upholding yellow orange pollen covered stamens. The leaves form a perfect cup for accumulating water drops. And the purple surrounding edges. A simple groundcover that is simply beatutiful.
Tradescantia pallida is a species of spiderwort commonly known as Wandering Jew, though it cannot be said when, where, or by whom it was first called this. But, considering the term's negative connotation, it would be safe to assume the originator's intent was not to highlight the plant's more favorable qualities. Other common names include Purple Heart and Purple Queen.
T. pallida can be primarily described as an evergreen scrambling perennial plant distinguished by elongated, pointed leaves - themselves glaucous green, fringed with red or purple - and bearing small, sterile three-petaled flowers of white, pink or purple.
Widely used as an ornamental plant in gardens and borders as a ground cover, hanging plant, or - particularly in colder climates where it cannot survive the winter season - houseplant, it is propagated easily by cuttings (the stems are visibly segmented and roots will frequently grow from the joints). It is shade-tolerant and can thrive in a wide range of soil conditions where it has not been intentionally cultivated and carefully maintained. In areas throughout the southern United States and Australia, it is considered an invasive weed and has defied many attempts at control or eradication.
As a houseplant, T. pallida is exceptionally effective at improving indoor air quality by filtering out Volatile Organic Compounds, a class of common pollutants and respiratory irritants, via a process known as phytoremediation.

For a great photograph, photo shooting time is as important as the quality of one's equipment ... Maybe even more ...
Great pictures in general call for great sacrifices on behalf of the photographer ... When the rising sun makes his first steady steps over the horizon, the photographer should already be at the desired place, his/her tripod should already be standing on its three feet and the camera's power switch should be set to ON ... That means in general less relaxing time ... Sometimes even no relaxing time at all ...
