here's an example
you with some friends wanted to help the community by planting trees, flowers etc.
3) you need to give good examples to the kids and teach them how to plant
4) make posters or videos with telling people what is good for the planet and how this helps
5) the grown-ups help the kids or some friends from your group plants
6) (you can select the trees that you like or the ones that live the most)
7) to save the planet, to live healthy
8) The people will be healthier and some diseases will disappear, we will have more oxygen leaving the ozone intact
hope that helped!
(it's a good exercise for the ones who are still learning facts)
