With out conservation wildlife would be gone. There would be no place for animals to live. So there would be animals roaming around the cities. Animals need a places to live. So people conserve land for the animals to live.
Conservation is also important so there is land in the future.
If there was no land in the in the future the world would be a dull place I think. If the entire wilderness is destroyed people will not have fun. The wilderness is a very fun place too. It is a good place to do a school project or learn. When you conserve you are also helping an educational value.
