Yes, climate change is an issue. But it's an issue we can solve more easily than we can colonise space or other worlds. Ultimately, the easiest planet to terraform is our own.
Yes . . . which is my point. Sorry if I'm not being clear.

"Terraforming" Earth won't be easy . . . but compared to colonizing other places in the solar system, it'll be a cake-walk.
 

From a certain point of view the only actual cost of space exploration is the consumption of materials and the pollution produced as a byproduct of launches. The money spent goes into the pockets of people who live and work on Earth. Only the materials that get used up or launched into orbit are actually "gone" . And space exploration is less frivolous than most consumption.

What other consumption is just gone? Here we launch materials away from earth, we cant get them all back.

If we eat something expensive on earth etc. the molecules are still here. And its not like the energy consumption of rockets is particularily low.
