In recent decades, the populations of bees and other pollinating insects have been threatened at a global level, as the balance of nature on which they based their evolution has begun to be significantly disturbed. With agriculture and animal husbandry becoming increasingly systematic and intensive over the last century, land use has changed dramatically. Widespread use of pesticides, reckless logging, deforestation for fodder cultivation and urban sprawl, forests that burn every year and are not reforested, pollution and the loss of much of the water table are just some of the factors that contribute
to the extinction of bees by 90%.
