While Roundup was initially well-received for being significantly less toxic than the herbicide it replaced, recent studies have shown that its use has potentially negative effects on human health, animals, and the environment. These effects are primarily associated with glyphosate, its active ingredient.

Various studies indicate that exposure to glyphosate is linked to a greater risk of developing cancer, particularly non-Hodgkin’s lymphoma.

Besides increasing the risk of developing cancer,   glyphosate is believed to have a harmful effect on the kidney and liver.

According to some findings, glyphosate can also interfere with the reproductive and developmental systems of the human body.

It is also alleged that glyphosate exposure can alter the development of the nervous system and the neurotransmission systems, in addition to causing oxidative stress.

Other studies suggest that glyphosate can disrupt beneficial gut bacteria and negatively affect microbial communities.

When it comes to animals and the environment, glyphosate is alleged to cause genetic damage and being acutely toxic to fish and birds. It is also believed to kill beneficial insects and soil organisms. Glyphosate residues have been found in soil, fruits, and vegetables, persisting for more than a year.

As you can see, glyphosate has a pretty bad reputation. However, it is important to note that studies are still underway to verify all the claims against glyphosate and the true extent of its effects.
