or,

Do you think that we should explore survival in space?

I do not think so, w. Why should we need to know how to survived outside of our own planet if Earth haves everything we need to live a plentybountiful life.

Instead orf wasting resources and money to know how toon researching how we can live ion another planet, what we should do is tonstead is use that money into takinge care of eEarth and explore other kinds of energy that do not cause significant damage in Earthto it.

This should definitely be broken into two sentences. I think it sounds more natural to say "Why should we learn to survive in space" rather than "Why should we need to know how to survive outside our own planet" but it's really a stylistic choice.

There were a couple of typos that I fixed but it was mostly stylistic changes. It sounds unnatural to say "what we should do is" in most sentences, so I rephrased it a bit. It also sounds weird to say "Earth" twice, so I rephrased the end of the sentence in a way that I think sounds better.

I do not think so, why should we need to know how to survived outside our own planet if Earth haves everything we need to live a plentyiful life.

The writing is good but you need to work on your tenses.
