What gives you hope?

This year in my Environmental and Resource Management class, we looked at a lot of global issues-both socially and environmentally-that are making big impacts in our lives. (peak oil, climate change, deforestation-anything along those lines) My teacher thought that it would be a good a idea to end the semester on a positive and productive note, looking at the things humanity is doing to improve global well- being. We researched different technologies and movements that are helping us move towards a brighter future. Outside our classroom, we received answers such as education, random acts of kindness, and active citizenship. So... in a time of such radical social and environmental change, what gives you hope for our future?
