Friend,

As bumblebees dance from flower to flower, it may look random, but in fact, they are using color memory to choose the buds with the right pollen.1

But a widely used chemical is impairing the bees' ability to remember and differentiate colors. A new study shows that glyphosate -- the main ingredient in the pesticide Roundup -- is hampering the pollinators' learning and memory, meaning that they can't forage properly.2

A mountain of evidence proves that glyphosate is harmful to the bees, to animals, and to us. The Environmental Protection Agency (EPA) is revisiting the continued use of glyphosate right now, and we need to ramp up our call for the EPA to ban the toxic substance.

Will you donate to Environment Colorado and help ban bee-killing pesticides?

Bumblebees are important pollinators, helping crops and flowers to grow. However, due to growing pesticide use, bumblebees are dying off.

Glyphosate in particular has been showing significant harm to the bees. Not only does it affect learning, the chemical impairs the bees' ability control their body temperature, affecting breeding.3

And it's not just bees being harmed by Roundup.

The EPA has found that glyphosate has adverse effects on nearly 93% of endangered species.4 Moreover, studies have linked the pesticide to an increased risk of non-Hodgkin's lymphoma and other cancers.5

The evidence against glyphosate is so strong that the EPA recently withdrew its 2020 interim decision approving of the pesticide.6 And Bayer has agreed to stop selling the pesticide for residential use...soon.7 But that's not good enough.

The EPA must ban glyphosate so that no one can sell the toxic pesticide ever again. We are still working to stop other bee-killing chemicals and protect our pollinators, but right now, we need to convince the EPA to stop the sale of glyphosate immediately.

Donate now to help save the bees from toxic pesticides.

Thank you,

Ellen Montgomery
