What have you done to make the world a better place?

I try to give a kind word or a helping hand when I can... I've done a series of art workshops to remote villages that made me feel like I was doing some actual work.. especially with kids and older ppl..
Also some periods of life, I adopt a grandparent, some old person in my neighborhood for sometime and I'm visiting or asking to help with little things like shopping etc. .. I became a vegetarian too so I hate animal farming, it's cruel. ..
