The decline of bumblebees is reversible, provided these cuddly-looking pollinators are provided with the correct environment to thrive, according to a groundbreaking two-year research study at the University of Sussex. For the first time, researchers demonstrated that reintroducing flowers in the farming landscape not only halts the decline of bumblebees populations but also reverses the trend towards healthy growth, as evidenced by far higher nesting density. This is major good news, when one considers that over seventy out of the top 100 human food crops, which supply about 90 percent of the world’s nutrition, are pollinated by bees.
