Environmentalists and activists work to boast bee population in Mexico

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.
