This works out to an average of about 1 species every 1,000 years which is considered the "natural" rate of extinction. The rate of species extinction is bound to rise continuously as population and human consumption grows; the UN expects that the world population will increase by 2 billion people within 30 years. Concerns have been raised for decades about whether global food production can keep up, and global waste is set to triple by 2100.
