I agree. Lovely intentions but ignorant. She seems to focus her conservation energies on opposing creation of protected parks in favor of leaving the Noble Tribal People (just who are THEY???) to be their noble selves. How 18th century of her.
But history seems to show that left alone, any humans will develop their land and use the resources for their own good even as they kill tigers or elephants as threats to their families or businesses or as resources to harvest.
True, tribal people are still being attacked and pushed off land they have lived in for generations -- by poachers, miners, developers and governments, in India, the US, Australia and Asia. But it is not about conservation of Nature usually. Protecting these people from corporate and governmental abuse is vitally important, as is protecting the land. But they are not always the same thing.
Nevermind the question of WHY is she climbing El Capitan?
