I am gonna get flamed a lot for saying this, but here I go anyways. The fact that Earth is getting a bit overpopulated doesn't make things any easier. Tons of new people being born that will probably not have a proper family or a proper education only hints that things may become worse. Especially in poorer countries, it is common for a woman to give birth to seven or eight kids during their lifetimes, and often these women don't have a proper education, they lack a husband, have to work minimum wages, and all that translates into the fact that she really can't take care of her kids, which then grow in the streets and are exposed to bad influences as they become adults. :(

And then someone comes along and says we are going to colonize space and save Earth for food and water. Everyone will have a position in this effort and will be paid by the most popular cryptocurrency for their efforts. huh? Oh wow I was dreaming.
