Twice a year in Hoima, a town in the northwest of Uganda, they have a parade that goes through the streets and collects plastic garbage from the ground. The town is full of plastic bottles and other things. The problem is: it is totally dry. And when it is raining, the water just flows away and doesn´t reach the roots of the trees. This problem has been well known for years. But because of the extreme dry season the problem is getting bigger and bigger. The government tried to solve the problem. But now the bishop of the Kampala region found a way to make the people more responsible. The religious leaders in the country have a huge impact on the Ugandans. The bishop for example encourages couples to plant a tree before they get married. And guess what – it is working.
