Gisele Bundchen

I'm a woman trying to balance family, work and friends like so many others out there.

I felt like my pregnancy was a sacred moment for me. I stayed in Boston and I didn't work apart from the contracts I have, and then I only let them use my face.

It saddens me that in the 21st century, with all our knowledge and power, we are hearing more and more stories of possible extinctions due to people's choice. We are responsible for our choices and the only ones capable of changing our future.

Yes, Brazil, like the whole world, stands to lose a lot in a climate-altered world. But it's also one of the major forces determining our future: It's the home of most of the Amazon rain forest.
