How can Kenyas national parks become more sustainable?

They can give money to the people/tribes of Kenya instead of building big and expensive hotels. Also the tourists/visitors can live with the Kenyan people/tribes instead of paying lots to stay in a hotel. If they stayed with the people/tribes they would get a better experience and more out of their holiday because they could eat the same food as they do. Any money they saved they could give to the people/tribes so they can afford to get their children into schools and have a better future. If they carried out/on this the people/tribes of Kenya would be glad for many more generations because any money left over could get passed on through the family.
