South Africa is the third most biodiverse country in the world. The country encompasses about and has about 10% of all plant species on Earth. South Africa and seventeen other countries are considered mega diverse which means those countries contain 70% of the planet's biodiversity. South Africa's unique geography allows the country to support such a diverse population of plants and animals. 
Ecuador is the 8th most biodiverse country on the planet. Ecuador contains almost 20,000 species of plants, 1,500 species of birds, 341 species of mammals and more than 840 species of reptiles and amphibians. Logging and oil exploitation is expected to destroy a great deal of this natural wealth. 
Despite having been selectively logged in the 1970s, the forest is still considered among the most biodiverse on the planet, containing about 20% of the remaining lowland forests of Sumatra. It provides habitat to over 300 species of bird, as well as the critically endangered Sumatran tiger and Sumatran rhinoceros. 
Boumba Bek, according to the Environmental News Service, "encompass a biodiverse group of plants and animals." Chimpanzees, forest antelope, Nile crocodiles and bongos are all found in Boumba Bek National Park. In addition, roughly 300 fish species, three of which are not named, swim in the park's rivers. The forests of Cameroon contain some of the highest population density of forest elephants of any nation, and Boumba Bek is no different, with an elephant density of roughly 2.5 for Boumba Bek and Nki combined. Boumba Bek was designated an Important Bird Area by BirdLife International. 
Zero waste agriculture is a type of sustainable agriculture which optimizes use of the five natural kingdoms, i.e. plants, animals, bacteria, fungi and algae, to produce biodiverse-food, energy and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process.
