Ecologists and biologists compared data of about 1,500 agricultural fields around the world, including corn fields in the American plains, oilseed rape fields in southern Sweden, coffee plantations in India, mango plantations in South Africa and cereal crops in the Alps. They analyzed two ecosystem services (i.e., processes regulated by nature that are beneficial and free for humans): the pollination service provided by wild insects and biological pest control service, which is the ability of an environment to use predatory arthropods present in the ecosystem to defend itself from harmful insects.
