Transcript for Honeybee population drops at an alarming rate
A 4x4 necessary here. Not just snowing here but also national pollinator week, and honeybees, as you know, have been struggling of late, and beekeepers have been reporting this spring a 40% loss in the hives we so desperately need just to put food on the table. The workhorses of pollination, fertilizing flowers and crops, over 30% of the food Americans eat is spawned by honeybees, and recently the population of these vital pollinators is dropping at an alarming rate. So we went to the only stand-alone invertebrate zoo in the world to look into it. Why do we think the bee population is in decline? So, there are a lot of factors that play into the decline of bees. Lack of habitat. Also pesticide use and pathogens. What about climate change? What about a warming world. So that could be a huge impact. Some of it has to do with when plants bloom. So if you're a bee and you come out in April every year expecting to see a certain flower blooming and now because of the changing climate it's blooming in March, you missed your window. Reporter: Those plants struggle to bear fruit. Let's check out our chief pollinators. Into the hives I go with zookeeper Sara Triplett. Look at all those bees. The young bees can excrete this wax out of glands on their abdomen and form it into these cells and then the bees will leave the hive and collect nectar from flewers. Reporter: But those negative factors now disrupting this necessary pollination process. Well, if you don't mind the bees are freaking me out. I'm going to check out the butterflies. These other butterfies facing similar fights. This is amazing. Pretty cool, huh. Very cool. How many butterflies do you have flying around in here? Over a thousand. Over a thousand. Reporter: From all over the world and our resident butterfly expert, 8-year-old Zelda oaks recognizes the importance. What would you tell the kids afraid of bugs who don't like them? I would tell them that bugs usually are helpful to people and you can help them help you. She sure is cute and butterfly pavilion is a cool spot outside of Denver. Things you can do to help out the bee population and butterfly population, plant plants that bloom all summer long and fall and through spring and that will help the health of the pollinators out there, not just that but buy local honey, I've got some local hive honey from rice's honey and they also have some local hive honey in new York. I've had some sent in so the honey that you have on set, guys is from the northeast so we're all going to have local honey. I could use some in my hot tea on this first full day -- Diane is eating it as we speak. I love honey, guys. This is really good honey.
