Unknown heroes. Patrick Mwalua dedicated his life to deliver fresh water for African animals. Each day he fills his water machine with fresh water and goes to the same place in savanna. He stops and beeps the signal. Wild animals which do not trust people run to meet Patrick. He opens the water tub and the water runs died to the special place in the ground. For the last 6 month he does it each and every year. A man who owns the water supply statins each morning meets Patrick. He agreed to give 10 thousand liters of water each day for free. Thousands of wild animals come there each day. Without Patrick they would have no chance to survive.
