Earthworms support a healthy soil ecosystem and increase soil fertility. They do this by breaking down organic matter and making nutrients available to plants.
The widely used pesticides glyphosate and 2,4-D are toxic to earthworms.
Without earthworms, the agroecosystem, the organisms and environment of an agricultural area, will be unable to support industrial farming.
If farmers want to continue to see high crop yields they must find ways to protect earthworms. This starts with replacing glyphosate based herbicides and 2,4-D.
A few alternative pest control methods include using more natural, organic pesticides, encouraging beneficial insects and pest predators, and employing improved farming practices such as companion planting.
Happy, healthy earthworms produce nutrient rich soil and encourage robust crop life.
If farmers change their methods and support earthworm populations, the agroecosystem will be healthy and crops will thrive.
