50% of all sea life has died since 1970. Terrestrial animal populations have declined 50% in the past few decades. By 2050 there will be as much plastic in the ocean as fish. The polar ice sheets are melting. Ocean levels are rising and could flood the world’s biggest cities. Storms are becoming more intense and affecting finance and insurance. Climate change is in the news everyday, surrounding every possible discussion, but what is it? You likely hear of kids screaming at adults about how evil they are and that they have stolen their childhoods. But who deserves attention? Climate change activists who want to push socialist policies, or libertarian climate deniers? I argue climate change should be completely bipartisan and does not even belong in discussions of vague morals or animal rights. Practising good environmentalism is beneficial for everyone.Sustainable development lacks central literature, so I wrote this book to help people learn more about the issues at hand with rational scientific thinking, rather than emotional appeals. I argue that we desperately need to act more sustainably immediately and that we do not need to wait for ‘deus ex machina’ to save us. Being more sustainable is achievable but it is an issue of society’s mentality and economics.If you want to understand sustainability better, see through the political propaganda, and learn how much you are harming yourself, read this book.
