If we turn off right now all machines on Earth, environment decline will still continue, at least, one hundred more years. So whatever good news they tell you within that term, it's not completely true. Now it isn't about not damaging the planet (more exactly, the question is no longer about doing things to the planet that damage ourselves); we've already damaged the planet.
Now we just can deliberate about to stop increasing the damage. You wouldn't mind changing your domestic habits if it only had to do with your personal living and the environmental news were great. Environment degradation doesn't care about our perception or ideology on it. We have spent some time accepting the causes; so we'd better start to get ready for accepting the consequences.
