Endangered+Species


 * Significant Endangered Species

Sharks**
 * The decreasing number of sharks can negatively impact the local marine ecology.
 * Finning and overfishing caused the population of scalloped hammerhead shark to decrease by 99% in 30 years.
 * "Sharks are definitely at the top of the list for marine fishes that could go extinct in our lifetimes," said Julia Baum of the Scripps Institution of Oceanography in California and a member of IUCN shark specialist group. "If we carry on the way that we are, we're looking at a really high risk of extinction for some of these shark species within the next few decades."
 * **The shark's prey can flourish because of the extinction of sharks; however, this can be chaotic for animals at the bottom of the food chain.**

 * Polar Bears**
 * Global Warming is causing the extinction of polar bears that is said to happen in the next century.
 * Currently, there are only 25,000 polar bears on earth, which is an extremely low number compared to the 50 million year range.
 * **Polar bears are on the top of the food chain, and once they are extinct, the food chain will be greatly altered.** For example:
 * The seal population will rise which allows Canadians to hunt them.
 * Arctic foxes and birds will have nothing to search for and they will eventually die.


 * Tigers**
 * There are three causes that lead to the extinction of tigers:
 * Poachers and hunters kill tigers for their fur, illegally
 * Loss of habitat
 * Human population is expanding and therefore, moving into the tiger's habitat
 * The population decreased from 10, 000 to 4,000
 * **Tigers are very important to the health of ecosystems. Without tigers, it will definitely affect biodiversity and places a risk on the health of people.**
