How do zoos help animals in danger of extinction?

Zoos help by allowing the species to re-create (have babies) in a safe environment. The usual predators are eliminated from the species' habitat. Veterinarians (animal doctors) are available to help promote healthy births and to help eliminate diseases that might kill them naturally in the wilds Zoos have cross-breeding programs that allow the strongest animals to be bred to each other giving the species a better chance of long-term survival.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
