Young people, when informed and empowered, when they realize that what they do truly makes a difference, can indeed change the world.
One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!
We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.
Every individual can make a difference every day by making conscious choices.
