National Football League superstar Tom Brady's model wife Gisele Bundchen, who has two kids, Benjamin, 10 and Vivian, seven, feels it is time each one of us play their part to save the planet.  In an essay she wrote for Vogue, Bundchen, said: "The only reason we're alive is because Mother Nature is giving us everything we need to survive. What do we do? We just take. We, as humans, believe everything is here to serve us, but that's not true. Earth is a living being. It's important for us to understand how lucky we are that we get to live on this beautiful planet with all these incredible resources."
