The United Nations has cited a global decline in bee populations as a serious threat to plants critical to people and their livelihoods. The threats against them are many, including climate change, pollution and pesticide use.

Bees are a vital link in global food chains. Indeed, the founders of this organization estimate that 80% of all food crops in Mexico’s Oaxaca State region are pollinated by bees. Quite simply, the agriculture industry would be in a world of trouble without them.

But many environmentalists and activists are working to boost bee numbers. CGTN paid a visit to one such group in southern Mexico.
