Positive:

1. I think, that zoos are good places for animals, because people are able to take care about wild creatures and help them to live a healthy life there.

2. Besides, zoos are a wonderful and safety opportunity to learn the wild part of our world for children and adults.

Negative:

1. I'm sure that zoos are real prisons for animals, because its workers limit species that live there and they can't live full-living life.

2. Despite fact that zoos try to set up the most full-detailed habitat for animals, everyone understands that it's impossible and it's clear that best living for a wild animal is a WILD space.
