I am about halfway through the book. I think that the main idea of the book is that people from around the world come together to make a difference in the environment. I have done all of the class activities. My favorite would have to been painting my pet rock. Or as my family calls them: people watchers. During the flower making activity I had a huge migraine so that's why I wasn't so thrilled with that one. But overall I think that the activates are fun, and seed folks is a good book.
