The red king crab is native to the Okhotsk and Japan Seas, the Bering Sea, and the northern Pacific Ocean, where it is an important economic resource. In Alaskan waters, red king crabs have historically been the second most valuable species to fishermen after salmon, although since the 1980s overharvesting has led to the closure of some areas to fishing. The king crab also has an invasive distribution in the Barents Sea. Since its introduction in the 1960s, the population has increased steadily and expanded its range, which now spans from Sørøya, Norway in the west and Kolguev Island, Russia in the east, and to about 72° north. Given the current state of knowledge on the impacts of red king crab on native benthic communities and fishes, it is difficult to draw any precise conclusions on the threat caused to the Barents Sea ecosystem and impact on native benthic communities.

Sea ice is frozen seawater that floats on the ocean surface. It forms in both the Arctic and the Antarctic in each hemisphere’s winter, and it retreats, but does not completely disappear, in the summer. It plays an important role for the climate and ecosystems. The extent and thickness of sea ice covering the Arctic ocean is significantly decreasing.

Arctic terrestrial ecosystems will continue to take up carbon, but warming and changes in surface hydrology will cause a far greater release of carbon.

A trophic level of an organism is its position in a food chain. Levels are numbered according to how far particular organisms are along the chain from the primary producers, to herbivores, to predators, to carnivores or top carnivores.

To live on the moon, you would need an atmosphere. On Earth the atmosphere is generated very largely by living organisms. To survive in your new atmosphere, you would have to take with you rather a lot of stuff that nature supplies here on Earth. Although many humans live in great luxury, more or less disconnected with the living world in their own perceptions, almost all of their well-being depends on goods and services delivered by things that live.
Everything we eat, for example, was recently nourished by ecosystems in the soil. These days the work of those soil organisms is often supplemented or disrupted by products synthesised from oil - another product of ecosystems, albeit ecosystems that lived some 360 million years ago. Cotton, wool, timber, and many pharmaceuticals are the product of the living world.
In 1981 Paul and Anne Ehrlich coined the term “ecosystem service” to refer to these things that humans get from the living world. A decade later the Millennium Ecosystem Assessment categorised the services into “provisioning” services such as food and fibre; “regulating” services such as control of climate, floods or disease; “cultural” services such as spiritual, cognitive, aesthetic and cultural benefits; and “supporting services” such as production of atmospheric oxygen, soil formation, and nutrient cycling, that themselves maintain the conditions for life on Earth.
This picture illustrates one of the more depressing findings of the Millennium Ecosystem Assessment, or MA; most of the ecosystems on Earth have been and continue to be degraded. The culprit, in every case, is the human species, either directly or indirectly. There are so many of us, and we demand so much from the planet, that ecosystem services are increasingly disrupted.
Among the out of focus tiles you will see “food” and “water”, and several other services that are missing letters here and there.
Cheshire Wildlife Trust - "Formed by glaciers retreating after the last ice age, the meres and mosses are a chain of bogs, marsh and fen wetlands of international importance, spilling out from Cheshire into Shropshire, Staffordshire and parts of north Wales. While only a fragment of their former size, they are still home to many plants and insects that are rarely found elsewhere."

Sustainable forest management involves the maintenance and enhancement of forest environments, ensuring longevity of forest ecosystems while allowing the best possible environmental, economic, social and cultural opportunities now and into the future. In Canada, the world’s largest exporter of forest products, harvest rates and strict jurisdictions are set to ensure long term ecosystem sustainability, protecting soil and water resources and 55% of all energy used by the forestry sector is renewable bio-energy.
