Life on earth is impossible without plants and other photosynthetic organisms. Plants are the most important living organisms for the ecosystem because plant harvest sun energy and, in turn, all other living organisms feed on plant directly or indirectly. Plants are used for food, fiber and most recently for fuel. Pollinisators such are bees are necessary for the reproduction and survival of many plant species, including plants for food. However, industrial agriculture and the use of pesticides have strongly declined bees and other insect pollinators. This bee decline has already decreased global food production. A review article by Nicholls and Altieri discusses in detail the problems of pollinators and how to solve this problem with novel farming practices.
