Detailed explanation-1: -The vast majority of the world’s food crops depend on natural pollination by these species, which are now threatened by intensive agriculture, pesticides, pollution and climate change. Pesticides, pollution and climate change are causing natural pollinators to disappear.
Detailed explanation-2: -Bees and other pollinators are declining in abundance in many parts of the world largely due to intensive farming practices, mono-cropping, excessive use of agricultural chemicals and higher temperatures associated with climate change, affecting not only crop yields but also nutrition.
Detailed explanation-3: -Our findings confirm widespread effects of land-use intensity on pollinators, most significantly in the tropics, where land use is predicted to change rapidly.
