Largest and Smallest Animals At Risk of Becoming Extinct

Researchers have found out that the size of an animal is important when it comes to extinction. Scientists have determined that the biggest and the smallest animals are more at risk of dying out than medium-sized animals.

Heavy animals are mostly endangered by hunting and poaching while the smallest creatures may die out because their living area is being polluted. Among the most endangered animals are elephants, lions and rhinos. Public awareness is large  and campaigns to save such animals have been around for a long time. It is the smallest species that get the least attention. Especially fish and frogs are in danger of dying out.

The species that are most at risk have a weight of over 1 kilogram. They are in danger of being killed because we need food, skin and other items.

According to the study, animals that are becoming extinct affect large ecosystems, like  forests, deserts and oceans.
