If the world was perfect, and there would be no pain or suffering, all of us would have a better life for the short time we are alive. i personally don't think it is possible, b/c to have a perfect world, everyone would have to work together to stop pollution, poverty, war, and stuff like that, and that would be hard b/c there are lots of people who don't care about these kinds of stuff, as long as they have what they want.

If everyone contributed something towards making the earth better, one day, we might actually have a perfect world, or one that is way better than the one we have today.

 
To have a perfect world, or one that is at least an improvement of the one we have today, people would have to: give up eating meat, drugs, alcohol, cigarettes, and they would have to use their cars less, to stop pollution. They would also have to stop murders, and suicides, and being stereotypical about people just b/c they are a little different, or have different views on life.
