Do yourself a big favor. Watch Greta Thunbergs TED talk. If you watch the whole video you will be moved at the end of the talk, I say. Give next generation a chance to survive.
What’s your ideas of action taking?
I have started to replace car travels under 10 kilometers with bicycle rides. That works fine. I get more fresh air, light form of exercise and so many “wow! you actually done what the rest of us also should do” comments. I haven’t discovered the downside of bicycling yet. I only experienced upsides so far.
I could do so much more probably but this is a start to decrease pollution.
