Patrick Kilonzo Mwalua is a name you have probably never heard of, but he is a hero in the animal kingdom.
Patrick lives in Kenya near Tsavo West National Park. Every day, he takes a drive to the park to deliver 3,000 gallons of fresh water to the elephants, buffalo, antelope, and zebras that live in the area.
The animals love Patrick so much, they even recognize the sound of his truck.
"There is completely no water, so the animals are depending on humans," Mwalua says. "If we don't help them, they will die."
Patrick spends his days driving around and filling the watering holes in the most needed areas. A lot of the animals don't even wait for the holes to be filled. They just drink from the truck.
"Last night, I found 500 buffalo waiting at the water hole," he says. "When I arrived they could smell the water. The buffalo were so keen and coming close to us.
"We aren't really receiving rain the way we used to," Patrick says. "From last year, from June, there was no rain completely. So I started giving animals water because I thought, 'If I don't do that, they will die.'"
The 41-year-old pea farmer also runs a conservation project called Tsavo Volunteers, which visits local schools to teach kids about the wildlife in the area and how they can help.
"I was born around here and grew up with wildlife and got a lot of passion about wildlife," he says. "I decided to bring awareness to this so when they grow up they can protect their wildlife.
Patrick's truck is very slowly and getting old, so a GoFundMe page has been started by people in the United States to help pay for his expenses. The page has already raised $95,000 in 5 months to help provide resources to Tsavo Volunteers.
