WHAT IS KILLING OUR BEES?

WE ARE CARE TAKERS OF OUR WORLD. WE MUST BE RESPONSIBLE FOR THE LIFE FORMS THAT SUSTAINS US. BEES, AND OTHER INSECTS PLAY A VERY IMPORTANT ROLE. BEES PRIMARILY POLLINATE OUR FRUITS, VEGETABLES AND OTHER PLANTS. MANKIND CANNOT LIVE WITHOUT THEIR HELPS. SO WHAT'S THE PROBLEM WITH THE MASSIVE AMOUNTOF BEES DYING ALL ROUND THE WORLD? AND WHAT ARE WE GOING TO DO ABOUT IT? WE MUST VIEW THIS MASSIVE BEE DESTRUCTION SERIOUSLY. OUR VERY EXISTENCE DEPENDS ON THIS LITTLE PRECIOUS INSECT.
WHAT DO YOU THINK WE SHOULD DO?
