My first instinct is to say I recycle, I buy my electricity from green providers, I reuse, buy second hand, work from home, eat veggie regularly etc. I do all of these things, but they are grossly outweighed by me simply existing. No matter how green I live, I still consume and produce waste, and so do my children.

How I make the world better: I collect litter at the beach and in parks and dispose of it properly. I also encourage my kids to do this. The positive effect on the environment is probably still outweighed by my consumption, but I can say that there is less trash on the beaches around where I live because of me. It's not much but its something.
