This part best express the central idea of the article.

Explanation:

According to “Paul Kingsnorth”, a former green activist, the future of humanity is black. He thinks global warming, melting ice caps, vanishing plants, species and a growing population is adversely affecting the environment. But nothing is being done to overcome these issues.  

He thinks that space colonization is not as practical as it was in 1950s. Back in 1950s, more resources were available, there were possibilities of new technologies which would help humans to reach other worlds. But today the change in environment and increase in population is making things difficult. We are now often distracted from facing the reality and trusting on to the things which are highly impossible.
