Some months ago I started asking people in my RC ongoing class to come to class with a good-news item about the environment. This was after a lot of work on the RC Community goals related to the environment. I had noticed that just focusing on climate change and the horrid effects of addiction to fossil fuels would keep people sunk [sad, feeling powerless].
At the start of the class, we share news about what people are doing about the environment. (The list of things people have mentioned is impressive.) This has had a good effect on raising awareness and on seeing that we, as individuals, can make a difference. Each little or big thing we do is essential to turning things around, just like it was the little or big things we did (and still do) that are causing climate change.
While correlation is not the same as causation, it is interesting to note that the number of low-emission cars and rooftop solar panels in our Community has increased over the same time.
