Mrs. Michell’s 4 th Grade Class

Only 200 or so Asian lions exist in the wild. A former royal reserve, India's Gir Forest, is the last home of this lion subspecies.

There are roughly 700 mountain gorillas remaining on Earth, and nearly half live in the forests of the Virunga mountains in central Africa. These gorillas live on the green, volcanic slopes of Rwanda, Uganda, and the Democratic Republic of Congo—areas that have seen much human violence from which the gorillas have not escaped unscathed.

There are only about 1,000 giant pandas left in the wild. Perhaps 100 pandas live in zoos, where they are always among the most popular attractions. Much of what we know about pandas comes from study of these zoo animals, because their wild cousins are so rare and elusive.

Siberian (or Amur) tigers are the world's largest cats. They live primarily in eastern Russia's birch forests, though some exist in China and North Korea. There are an estimated 400 to 500 Siberian tigers living in the wild, and recent studies suggest that these numbers are stable. Though their northern climate is far harsher than those of other tigers, these animals have some advantages.

The black rhino once roamed most of sub- Saharan Africa, but today is on the verge of extinction due to poaching fueled by commercial demand.

Only Native Americans are currently allowed to hunt walruses, as the species' survival was threatened by past overhunting. Their tusks, oil, skin, and meat were so sought after in the 18th and 19th centuries that the walrus was hunted to extinction in the Gulf of St. Lawrence and around Sable Island, off the coast of Nova Scotia.

Elephants use their tusks to dig for roots and water, strip bark from trees, and even fight each other. Unfortunately their ivory has gotten them into a lot of trouble. Because ivory is so valuable to some humans, many elephants have been killed for their tusks. This trade is illegal today, but it has not been completely eliminated.

Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.

Objectives: Students will complete the Preserving Biodiversity family activity; describe reasons why biodiversity is important; research and take notes on five endangered species; discuss the ways that human activities contribute to declining biodiversity; and devise plans to help protect endangered species. Standard 1 Students will understand the relationship between the physical geography in Utah and human life.
