The Earths Sixth Greatest Extinction By Igor Milgram, Derrin Miller, Johny, Scott Richmond

The 5 Past Extinctions Ordovician-Silurian extinction: 439 million years Late Devonian extinction: 364 million years ago Permian-Triassic extinction: about 251 million years ago End Triassic extinction: roughly 199 million to 214 million years ago Cretaceous-Tertiary extinction: about 65 million years ago

Current Extinction The current extinction is beginning to rival all of the last five extinctions. It is the first extinction in earths history that is cause by a biotic source instead of physical cause.

The Current Stats We are currently losing 40,000-50,000 species a year That is roughly 137 a day. Since 1600, 83 mammals species and 113 birds have become extinct.

All the stats Threatened animal and plant species : 11,046 Known species humans have forced to extinction in past 500 years: 816 Threatened animals and plants in the United States: % Known Amphibian species 24% Known of Mammals 25% Known of Reptiles 30% Known of Fish

The First Cause The invention of Agriculture is the first cause of this problem. It let us become separated from other species. We changed the earth for our needs.

Domino Effect All species have an effect on each other If one species dies it could cause the co- extinction of another species Some species directly affect the health of hundreds of other species.

Current Causes Pollutants Pesticides Ultra-violet radiation Climate change Habitat loss from agriculture and cities Hunting and Poaching Man Made Borders Many more…

Fences Humans love to fence off space they say belongs to them. This stops animals from getting to needed food sources. Fences cuts off food sources for animals which leads to village attacks, which leads to more killing of animals.

The Disappearing Forests Roughly 21% of the land-mass is covered with closed-canopy forests There are only formal bans on 9% of the worlds forests. The Earth's forests hold over 50% of all known species. Top Five Countries Russia: 23.3% Canada: 12.8% Brazil: 12.6% United States: 8.2% Democratic Republic of the Congo: 4.0%

Why? Why?

Is there a way out? The world needs international cooperation to sustain the environment. Countries ban the cutting down forests Reduce Co2 emissions. Reduce Human Population. End destruction of land for Agriculture.

United Nations Environment Programme Monitors status of global environment Making international agreements Combining economic development and environmental protection. Allows the transfer of knowledge and technology for sustainable development.

What can each of us do? Reduce our carbon footprints Learn about Local endangered species RECYCLE!!! Protect wildlife habitat.
