This symbol is presented like a metaphor of us and our earth. It is a big organism and we, people, are parts of this organism, we are not separate. And the earth is also just a part of even bigger organism. Our earth is like a tree with the roots which extend to the vast cosmos. Everything is interconnected. We believe that this understanding of being one with the universe can raise people’s awareness about our environment, us and our function. This can lead to some positive changes that our planet desperately needs. More info here: http://www.radicalcourse.com/all-is-one-with-the-universe-gaia-symbol/
