The lion population in Africa is critically endangered. Most lions now live in eastern and southern Africa, and their numbers there are rapidly decreasing, with an estimated 30–50% decline per 20 years in the late half of the 20th century. Estimates of the African lion population range between 16,500 and 47,000 living in the wild in 2002–2004, down from early 1990s estimates that ranged as high as 100,000 and perhaps 400,000 in 1950.
This is text from National Geographic Facebook site (about lion saving campaing Build A Boma):
“Protecting livestock with fence enclosures helps protect lions from retaliatory killings. Bomas are a simple solution for this problem. Find out how you can support National Geographic’s Build A Boma campaign to help save lions and other big cats.”
And this is text from mainpage of buildboma.org:
Build a Boma is a campaign from National Geographic’s Big Cats Initiative that is saving lions and other big cats. Every dollar raised will go directly toward building and maintaining livestock enclosures called “bomas” in Kenya and Tanzania. Protecting livestock from predation helps protect big cats from retaliatory killings. Bomas are a simple solution for a big problem. Even a small contribution can make a big difference. A boma costs only $500 to build and $25 a year to maintain. It’s a proven way to decrease the killing of lions.
