The weed killer Roundup has been linked to cancer. It’s time to ban it.

Roundup's main ingredient is a probable human carcinogen, yet it continues to be the most widely used herbicide in the world. The EPA must ban it, unless and until independent research proves it safe.

UPDATE: Bayer reformulated its residential products to be glyphosate-free, but its agricultural product still contains glyphosate and it gets sprayed on millions of acres of farmland every year.

Bayer may have stopped selling glyphosate-based herbicides for residential use, but its agricultural product still contains glyphosate and gets sprayed on millions of acres of farmland every year.

Why does the Environmental Protection Agency (EPA) still allow the sale and use of a weed killer linked to cancer?

It’s because the EPA has long taken Monsanto — now Bayer — at its word when the chemical manufacturer claimed its product is harmless. But Monsanto’s own documents and emails have revealed the company’s deceptive efforts to manipulate the media in favor of its product’s safety.

Monsanto has worked hard to convince us its product is safe — but meanwhile, the World Health Organization has labeled glyphosate as a “probable human carcinogen.” 

Our families’ health isn’t worth the risk. The EPA should ban Roundup unless and until it is proven safe by independent research.

Toxic glyphosate is everywhere

Even if you don’t use it in your own lawn or garden, glyphosate is nearly impossible to avoid contact with.

So much glyphosate is used in agriculture that traces of it creep into food and drink of all kinds. Traces of glyphosate have been detected everywhere from ice cream and children’s cereal to beer and wine.

If Bayer can take glyphosate out of some of its products, it should take it out of all of them.

That’s why calling on the EPA is so important. The agency has the power to regulate the use of glyphosate nationwide — that’s how we can keep it off of store shelves, out of public parks and gardens, and far away from the fields where the food that eventually makes its way onto your table is grown.

What are the health risks associated with glyphosate exposure?

Studies have linked glyphosate-based herbicides, such as Roundup to cancer, reproductive problems and other health issues. 

Exposure to the chemical can be especially dangerous for children. Early contact with the chemical can result in liver inflammation and metabolic disorder in early adulthood, which could lead to liver cancer, diabetes and cardiovascular disease later in life.

Monsanto has settled more than 100,000 Roundup-related lawsuits and has 30,000 lawsuits against it still pending. The company has paid plaintiffs about $11 billion as of May 2022.

Why should Bayer be able to sell a product containing potentially carcinogenic chemicals, even as more people are exposed to glyphosate and more victims come forward?

Together, we can keep our communities safe from this toxic herbicide by banning it outright.

Your voice can make all the difference. Add your name to support a ban on Roundup today.
