Trespass grows are large-scale operations, with plant counts numbering anywhere from 1,000-80,000, and they are largely funded and operated by drug trafficking organizations. They are uniformly conducted with flagrant disregard for environmental and social well-being.
The use of these chemicals causes toxic contamination in all aspects of the ecosystem. After these chemicals are dispersed from grow sites and leeched into the soil and water supply, they slowly make their way through the entire food chain. From insects to scavengers to birds, smaller animals to bigger ones, evidence of chemical contaminants from trespass grows is being discovered.
