If you’re familiar with gardening or landscaping, you’ve probably heard of glyphosate, the main ingredient in many popular weed killers like Roundup. Glyphosate has been widely used for decades in agriculture, home gardening, and even public spaces to control weeds. But as more research is conducted, a clearer picture is emerging of its adverse effects on the environment—and it’s not looking good.
In this post, we’ll take a closer look at glyphosate, examining why its widespread use is harming ecosystems, biodiversity, and even human health.
What is Glyphosate?
Glyphosate is a synthetic herbicide developed in the 1970s and has since become one of the most commonly used herbicides worldwide. It works by inhibiting a specific enzyme pathway (the shikimic acid pathway) that plants need to grow. This pathway is present in all plants but absent in animals, which is why glyphosate was initially thought to be relatively safe for non-plant life. However, it turns out that its impacts are far more extensive than originally understood.
How Glyphosate Harms the Environment
Soil Health Degradation Glyphosate doesn't just impact plants above ground; it also disrupts soil ecosystems below the surface. This herbicide can kill beneficial microbes in the soil that are crucial for healthy plant growth, including bacteria and fungi that assist with nutrient cycling and soil structure. Glyphosate can persist in soil for weeks or even months, disrupting the soil ecosystem and reducing fertility over time.
Impact on Pollinators and Insects In killing weeds and other plants that many insects depend on, glyphosate indirectly harms insect populations, including pollinators like bees and butterflies. Glyphosate-treated areas lack the wildflowers and native plants that pollinators rely on for food and habitat. The declining availability of these resources has contributed to significant reductions in pollinator populations, which are essential for a healthy ecosystem and for food production.
Contamination of Waterways Glyphosate can easily wash into rivers, lakes, and other bodies of water through runoff from agricultural fields and urban areas. Once in waterways, it affects aquatic life, including fish, amphibians, and other species that are sensitive to chemical changes in their habitats. Studies have shown that glyphosate exposure can interfere with reproduction in fish and reduce populations of algae that other aquatic animals rely on for food. In short, glyphosate can alter entire aquatic ecosystems.
Threat to Biodiversity Glyphosate use promotes monoculture farming, where a single crop is grown over a vast area. This practice reduces plant diversity, eliminates habitats for many species, and increases dependence on chemical inputs like herbicides. As these habitats disappear, so do the diverse species that depend on them, leading to a reduction in biodiversity and disrupting natural ecological balances.
Risks to Human Health While glyphosate’s impact on human health is still being studied, there is evidence linking glyphosate exposure to various health issues, including cancer, hormonal disruption, and antibiotic resistance. The World Health Organization has classified glyphosate as “probably carcinogenic to humans.” Additionally, glyphosate residues are often found on food crops, meaning that this chemical makes its way into our diets. These health risks make it especially important to consider how we use this chemical and seek safer alternatives.
Alternatives to Glyphosate: Toward a Healthier Approach
As awareness of glyphosate’s environmental and health risks grows, so does the interest in safer alternatives. Here are some approaches to consider:
Manual and Mechanical Weed Control: While more labor-intensive, hand-weeding and mechanical tools are effective ways to control weeds without chemicals.
Natural Herbicides: Vinegar-based herbicides, essential oils, and other organic weed control methods can help reduce reliance on synthetic chemicals.
Mulching and Ground Cover Crops: These techniques help suppress weeds by covering bare soil, thus preventing weed seeds from taking root.
Integrated Pest Management (IPM): This sustainable approach combines biological, cultural, and physical methods to manage weeds in an environmentally friendly way, reducing the need for chemical herbicides.

A Call for Change
The widespread use of glyphosate represents a major environmental challenge, one that affects soil health, biodiversity, water quality, and human health. As we learn more about its impact, it becomes clear that relying on glyphosate is neither sustainable nor safe in the long term. By supporting alternative weed control methods and choosing more sustainable practices, we can protect our environment, promote biodiversity, and take meaningful steps toward a healthier future.
Our ecosystems—and our health—depend on it.
