Threats & Uses #1: My Notes

Tundra: the melting of the permafrost is a threat to this biome. It's a result of global warming and could radically change the landscape and what species are able to live there. Oil spills are another threat that can kill the wildlife and significantly damage the biome's ecosystems. The tundra biome has been used, throughout history, as a subsistence hunting, fishing and gathering of plants. Desert: global warming is a threat as it increases drought, which dries up waterholes and makes it harder for organisms to live there. Grazing animals can also be a threat as they can destroy many desert plants and animals. This biome contains substantial mineral resources which people extract and use. Tropical Rainforest: logging is a threat as it damages the environment and destroys animal's homes. Power plants and other industries are a threat too as they cut and burn trees to generate electricity. This biome feeds our global food supply. (Use)
