A Story of Change
La Paz School is a rural school in the mountains of Central Colombia. A few years ago teachers and students decided to do something about the environmental problems they had. Deforestation and bad management of waste was their main concern. As a result they created an environmental group to look for solutions.
First they researched information about the people, their business and the impact of their actions. Then they organized a campaign to protect the rivers in their town. They talked to the local authorities about prohibiting the industries from dumping waste. They started teaching about recycling methods and the whole town signed a petition to stop the destruction of their forest. They planted 2,000 trees near the river.
Now people in our town are happy with the results. Liliana, a 15 years old student in La Paz school, said: "Now we have lots of trees around our houses and parks; the rivers are clean and we understand that when people work together to support a cause the little things that everyones does can create big changes
