What are the major threats to your biodiversity?

Answer 1

Tundra (specifically arctic tundra with permafrost) and rainforest are sometimes considered endangered biomes. Tundra because it is easily affected by short, warm winters, and rainforest because of human use issues.

Some other biomes have also been called "endangered". For example, the deciduous forest biomes in England and North America were almost lumbered and farmed away. No biome can actually become "endangered", because they are all created by the geology and meteorology of the area. For example, if the Earth were tipped on its side and the Arctic became the equator, all existing arctic tundra would vanish; however, the new Arctic would eventually become deforested, and populated by only short grasses, lichens, and mosses, re-creating the arctic tundra biome.

Actually, if the Earth were tipped on its side, with its axis in the ecliptic, then we would probably see some entirely new biomes. One based on constant sun for six months and constant darkness for six months, and some others based on varying between 12 hour days and constant twilight.

Answer 2

Humans reduce biodiversity by altering habitats, hunting, introducing invasive species, releasing pollution into food webs, and contributing to climate change.
