The 5 best Ted Talks for students of Environmental Studies and Earth Sciences

3. Why I live a zero waste life.

Lauren is an Environmental Studies graduate from NYU and former Sustainability Manager at the NYC Department of Environmental Protection, and the amount of trash that she has produced over the past three years can fit inside of a 16 oz. mason jar. Lauren Singer is author of the Zero Waste blog, Trash is for Tossers and founder of organic cleaning product company, The Simply Co. Her work has been profiled by New York Magazine, MSNBC, NBC, AOL, CNN, Yahoo, Fox Business, BBC and NPR, among others.

4. Which country does the most good for the world?

It's an unexpected side effect of globalization: problems that once would have stayed local—say, a bank lending out too much money—now have consequences worldwide. But still, countries operate independently, as if alone on the planet. Policy advisor Simon Anholt has dreamed up an unusual scale to get governments thinking outwardly: The Good Country Index.

5. The Earth is full.

Have we used up all our resources? Have we filled up all the livable space on Earth? Paul Gilding suggests we have, and the possibility of devastating consequences, in a talk that's equal parts terrifying and, oddly, hopeful.
