cnn.com. and we want to switch it up a bit, honey bees, which have been crucial in the pollination dramatically declined for a whole number of reasons. but some scientists are finding a creative way to make their performance and immune system work better. we have more on that in this week s mission ahead. bees are responsible for pollinating one-third of all crops worldwide, but pesticides, parasites and climate change are all making it harder for bees to survive, and populations are declining impacting the nearly $20 billion they contribute to u.s. crop production. in fact, this past winter saw the highest honey bee colony losses on record, but the company bee flow thinks they can give bees a boost with a nutrient packed super food formula they say improves their performance. we say we are developing strong and smart bees. feed the bees the formula, and they can work longer and in colder temperatures. helpful for crops like these
almond trees in california, which have short pollination windows. very close from here, we ve done a trial where we see that our bees were doing seven times more flights under really cold temperatures. with no automated way to monitor bee performance, the bee float team spends hours each day staring at trees counting bees. we know how many bees the flower requires to develop a fruit of x size. reporter: so far it s working. in argentina, their trials increase crop yields up to 90% and made fruit like these blueberries in oregon 22% bigger. at the moment, bee flow knows it can t address ever issue impacting bees, so for now their goal is to make what we already have better. there s a lot of questions that are still waiting for answers, and we think that this is just the start of our journey on pollination that has been underestimated by the agriculture industry.
