You can start by asking your parents to buy 100% natural products, including chemical free household cleaners, such as laundry detergents, dish soaps, or even products like shampoos, conditioners, and deodorants. As a stay at home wife and mother to 1 year old puppy, I spend most of my time helping people just like you learn about the best eco-friendly products available, scientifically proven. If you are interested in getting more information, have your folks check out my blog 2010Pickles to learn how you can keep your house 100% all natural and chemical free. I love the product line I use, because I know that I'm buying products that are not polluting the earth in any way, and are safe for my home and family.

There is always some community service project you can partake it. Think of something you hate, and find a way to decrease that. I come from not the nicest area, crime is high, intolerance is high, unemployment is high, child abuse is high, education is low. I looked at all the things I hated and found a way to help decrease those in some way; for me that was doing things to help promote education. I spent no money, I was able to volunteer at schools, libraries and churches; I helped people learn how to read and that helped them change their lives. Find something you want to attack and work on it; you will find a way.
If as for right now, your stuck then I suggest doing things like freerice.com where you'll be helping fight world hunger.
I started buying fair trade products, among other things. Slavery is not dead! There are currently 27 million slaves, and this is not just human trafficking. The top three products that involve slave labour are coffee, tea, and chocolate. So, if this sounds good to you, you can start buying these products fair trade.
At my university, we have a club that is dedicated to help stop modern day slavery. There is a good little information section here: http://be-the-voice.org/slavery-through-the-ages/
This is also a good place to start: http://www.antislavery.org
