Why do you need habitats?

Habitats refer to places that living things live in. Everything needs a habitat. Take yourself, for instance. What would you do if you did not have the place to live in like you are living in now? Every living thing needs a place to live, that is their habitat, that is where they are at. And then realize that we all share the Earth's habitat. And we really need it as it is our only place to live. There are no habitats in space, that we know of, yet.
