Massive Extinctions from Human Activity

http://www.globalissues.org/article/171/loss-of-biodiversity-and-extinctions#MassiveExtinctionsFromHumanActivity
Biodiversity is an essential part of life.  Most humans know this, however they do not care enough to stop those actions that they take that cause extinctions and decrease biodiversity.  Our current extinction rate on Earth is 1000 times greater than it was before human actions started affecting the environment.  Human actions are significantly destroying the biodiversity of Earth. Here are some facts presented in the article

At threat of extinction are :

• 1 out of 8 birds
• 1 out of 4 mammals
• 1 out of 4 conifers
• 1 out of 3 amphibians
• 6 out of 7 marine turtles

75% of genetic diversity of agricultural crops has been lost

75% of the world’s fisheries are fully or over exploited

Up to 70% of the world’s known species risk extinction if the global temperatures rise by more than 3.5°C

1/3^rd of reef-building corals around the world are threatened with extinction

Over 350 million people suffer from severe water scarcity

If humans do not change their actions, than animals and plants will continue to go extinct and continually decrease the biodiversity of Earth.
