How can science save endangered species of animals?
Most often species are endangered due to something that mankind has done, whether or not it had anything to do with the species itself. Loss of habitat is a big problem, loss of prey species or other food item, pollution, etc. Science has the job of examining the how and why species are endangered, and to research possible cause/effects and solutions if possible. Take for example the bald eagle – which was registered on the endangered species list in 1967. Due to exposure to DDT and lead via the food chain, the reproductive rate of bald eagles plummeted sharply – and no one could understand why. It was discovered that DDT was being passed through the food chain (and being bio accumulated in the body of the bird) and it was affecting the ability of the eagle to lay eggs with shells that could protect the hatchlings – the shells would break during incubation. With a ban on DDT (as well as a phasing out of most lead shot for waterfowl), the bald eagle has slowly began to make a comeback i
