Depends on what "world" you mean. If you mean it will make the people in my life better, I would. If it would increase the quality of life for a small group of people on the other side of the planet I knew nothing about, no.
I don't care about making the entire world a better place, I'm only focused on how I can make MY world better, because I only care about the people I come into contact with. Sounds selfish, but it's what I believe.
