I came across this video a couple of weeks ago when I was procrastinating on Facebook. I’m Facebook friends with Nina Church — we were actually BFF’s in pre-school before her family moved to California — and saw that she posted this video of her and her brother’s TED talk. It turns out that she’s a teen advocate for social entrepreneurship (as is explained in the video) and that her family runs the company Nika water, which sells bottled water and donates the profits towards providing clean water in impoverished countries. It’s a great company and their video is really inspiring, so definitely check it out!
