Pesticide management

Some pesticides and herbicides are known carcinogens, while others play a role in endocrine disruption and affect the nervous system. These chemicals contaminate rivers and groundwater through rainwater runoff and eventually make their way through the food chain to people.

This feature requires the creation of pest management systems that reduce pesticide and herbicide use and eliminate highly toxic chemicals. Most pest management systems do not prohibit the application of harmful chemicals, so this feature further requires that only approved products are used.
