Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy, contributing adult. In fact, it is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city, helped local farmers and provided an income for poor people there.

　　When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka's streets, attracting rats and disease, they discovered that 80% of it was natural waste. So they educated the poor people in the city to compost(把......制成堆肥)this waste. They knew that they would have a market for the end product because local farmers were struggling with chemical fertilisers(化肥)which were expensive and had reduced the natural minerals in the soil over the years. At first, they were refused, but once they were able to persuade them that there was money to be made, the project took off. In 2009 sales were $14, 000.

　　Drayton is optimistic that in ten years Ashoka will be making really serious, practical progress in bringing about social change by changing the way we look at economic development.
