The survival of humans in outer space is not possible without first studying nature.
We humans are now exploiting the world in a very rapid manner. Some countries are thinking that colonizing outer space is essential for the survival of human life in the universe.
Famous scientist Stephen Hawking says that if we continue developing our technologies in this way, we can achieve and learn to live in space within 200 years, but looking at the present scenario of the world economical and ecological problems, it is too difficult that the world cannot tolerate up to even 100 years?
We humans were born just 200 thousand years ago, but Nature itself is 4.5 billion years old. So the technology which we made is always less efficient. less durable compared to nature. So human life in outer space is only possible if we learn many things from these 4.5 billion years of geniuses (as noted by Janine Benyus).
Some research has already been made like "Life in Biosphere", but learning "how the these species evolved?" is now more important than "how do these species maintain their balance and their design principles implemented to sustain not only them but also the system?" We need to learn from nature so that we can prosper on other planets, too.
