There so many ways to go green, but first we should stop our busy life for a moment and think about it. Think about future and our children. With small changes in our habits we can save the planet(or at least try it). I start with:
Repair all water leaks in my house(usually nobody take care about toilet leaks).
Save energy-it's so simple. In my house a had replaced all light bulbs with fluorescent ones. Also I recycle my electronics(google it - there so many companies that will buy your old staffs). And don't by electronics because our neighbor own something you don't have. Stop compare your live with the others. If you want to go green you must make some changes in your lifestyle--ride a bike or at least change your fancy powerful car with more economic one(and cheaper one:) ).
Well, I can continue all day long, but the most important think is to change our heart, start with small changes and don't stop. It's up to us!
