This green beach umbrella meant to be as a symbol or analogy of a human invention made to protect the human lives (from sun rays). And even in a bigger scale, the earth from the dangerous sun rays. The umbrella reminds us to take the earth into cover, to protect and save it. If we can invent something as simple and useful as an umbrella, we can do the same to protect the earth. Simple, ordinary things which could save the lives of billions.
