How Can I Save the World?

I'm looking at resources and sustainability at school, and its making me so sad and frustrated. Why are people so stupid? Can't they see what they are doing to the environment? They are just taking and taking resources without thinking about the consequences in the future, but they won't be able to take anymore once its all gone! Powerful corporations only care about the amount of money they make and will do anything to get it. Animals are becoming endangered because their habitats are being destroyed, fish and whales are disappearing due to over fishing. I'm ashamed to be a human…

I feel so passionate about this, I hate seeing everything bad that's happening in our world today and it makes me so motivated to do something about it. What can I do to help that will make a big impact? What should I avoid buying e.g. kinds of food? How can I cut down on energy usage apart from switching off lights? How can I save endangered animals? How can I be an eco-friendly tourist? Also, my goal is to plant 1 million+ trees in a rainforest sometime in the future, how would I begin a project like that?

Sorry for all the questions, but answers would be much appreciated

Thanks xxx
