As long as species have been evolving, species have been going extinct. It is estimated that over 99% of all species that ever lived have gone extinct.Nowadays many animals are facing extinction such as Siberian (Amur) Tiger, Loggerhead Turtle, Northern Bald Ibis, Lion-Tailed Macaque, Mandarin Duck, Mountain Gorilla, Jackass Penguin, Blue Whale, Komodo Dragon, Golden Lion Tamarin, Californian Condor.Some people may ask “Why bother with conservation?” We now realize that it is important to maintain the planet’s biodiversity, the variety of animal and plant life, abundance and wild habitats.The more species disappear, the more entire eco-systems become defenseless and would eventually fall apart as the links in the food chain become broken. For example, certain animals only eat certain plants and those plants may need that animal to pollinate it or spread its seed. Without one, the other is also likely to die out.People all over the world are working to help some endangered animals from extinction. There are conservation organisations which try to make people aware of the problems facing wild animals. Some of the ways in which they are being saved include habitat protection, captive breeding, setting up nature reserves and parks and using alternative products in place of products from rare animals.Today, the problem of extinction is one of the most important. I think the first step towards saving animals is to learn as much as possible about them. If we know where and how they live, and what they need to survive, then it will be easier to help them.
