Imagine the brilliant colours and smells of fruit in a Caribbean market, the vast variety of tins and jars in a North American supermarket. Imagine how many kinds of street music there are, the different ways children play with swings and kits and boats. Imagine the different seasons. Then imagine things that are the same worldwide - land and trees and creatures being destroyed, wealth and poverty spreading. Imagine believing in good hope, a future when life will be better.
