pretty much half of the world's population should be concerned about the environment, because their environment is slowly becoming impossible to live in. i'm thinking for example of the greater part of india, northern africa or even southern italy, greece, spain, a great part of south america, mexico, caribbean america, the hottest states of the u.s., some areas in australia, and so on.
climate change used to drive me crazy, because it's a well-known issue but most don't give a fuck. so i have decided i won't care about this anymore. i will just do my part, for the sake of my conscience. i will do as much as it's reasonable to ask from a single person. and that's it.
i don't have children, so i don't have to worry about what the world will have become in 100 years from now.
