environmentalists
such as the World Wildlife Fund often study large carnivores in order to 
assess the health of an 
ecosystem
. The Arctic 
food chain
relies on the polar bear. In addition, 
donations are more commonly offered for the protection of large animals such as bears or 
elephants. People in general are less interested in 
conservation efforts
that protect small 
wildlife, such as plants or insects. However, by using donor money to protect the habitats of 
larger animals through 
reforestation
and similar programs, entire ecosystems with many 
threatened or endangered species can be saved.

It is important that animals such as the polar bear make it onto the endangered species list. Once 
they are on the list there are laws that protect these animals from being hunted for food or sport. 
Agencies also receive money and tools to protect the habitat and 
recover
the species. The goal of 
removing the animal from the list is often achievable. Since the Endangered Species Act was 
introduced in the US in 1973, many species have been taken off the list due to increased 
populations. In fact, it is rare for a species to go extinct after they make the list. Sadly, many 
species do go extinct while waiting for consideration.
