Transcript

Humans, by unsustainable methods of gathering resources, have undermined the biodiversity of the planet. Natural animal habitats are destroyed and species used as food, or seen as threats are sometimes hunted close to extinction.

It is estimated that we currently lose 0.1% to 0.01% of all species on Earth in a single year.

Most endangered animals are top predators, like lions and tigers, and bears (oh my) mainly because humans hunt them out of fear and to protect livestock.

Because cougars are a top predator, they were mostly hunted and killed to "protect" people. However, since the cougar was the deers main predator, the deer populations exploded to the point where deer are considered pests.

Conservations happens in two ways.

In situ (In position) and En situ.

Both ways have their benefits and their disadvantages.

Animal Extinction

Conservation Efforts

Despite general ignorance to the amount endangered species, people have tried to step up to help save endangered species. Various NP Organizations and government groups have funded and helped conserve biodiversity.

Endangered Species.

Of close to 45,000 species assessed by The International Union for Conversation of Nature, close to 17,000 are threatened by extinction.

Since 1500, at least 905 species have been confirmed to be extinct.

Previously in Earths History, there have been 5 major extinctions.

  • Ordovician- 438 million yrs.
  • Devonian- 360 million yrs.
  • Permian- 251 million yrs. 95% of all species were lost.
  • Triassic- 199 million yrs.
  • Cretaceous- 65 million yrs.

Ecuador has the most endangered species in the world with 2,221 total, and close to 1700 plant species endangered, more than twice any other country. The USA has the second most endangered species at 1,203 total.

Why Save Animals?

Mr. Hoy did mention briefly about biodiversity and the possible mystery cure plants and animals that we could use. We also could lose possible new pesticides, cross-breeding opportunities, and other species that would benefit us commercially.

We are currently in a mass extinction event, projected to be far worse then the death of the dinosaurs.

Species are going extinct at a ever-quickening pace, not from a natural disaster, but at the fault of one species.

Humanity.

Extinction

Ways YOU can help!

  • Adopt a endangered species at WWF.ca.
  • Donate to various organizations
  • Support national parks and conversation efforts

Extinction is the end of a group of organisms, usually just a species.

  • The moment of Extinction is considered to be when the last surviving individuals die.
  • Extinction becomes certain when no individuals aren't able to procreate.
