People fear death usually because they are afraid of what comes next...the unkown. People want to make a better future so that their lives may not be miserable (aka full of pollution, war, corruption etc.) We want to create a better world so people do not have to suffer. Sounds cliche, but when you think about it, you'd want your children to live on without injustice and stuff like that, and when millions of parents think the same thing, well, big changes could happen.
