Jane Goodall, a brilliant animal researcher and activist, set out with endless determination to save chimpanzees and their natural environment from extinction. Goodall fought the felling of trees and initiated a system that obliges the residents of Tanzania to engage in entrepreneurship that is sustainable - planting coffee, for example. This is how the residents gradually began to engage in organic farming, and avoided cutting down trees. The forest began to spread out and reconnect with other forests, thus allowing the chimpanzees to breed with groups of females from different forest areas. Jane Goodall dedicated herself to vegetarianism and veganism, and fought against medical research on monkeys and against non-subsistence hunting. However, she is not opposed to keeping monkeys in captivity, as long as they are treated fairly.
