What is a common risk associated with pesticide drift?

Pesticide drift refers to the movement of pesticide particles or vapors through the air to unintended sites, which can pose significant health risks to humans and non-target organisms. This includes not only other plants and insects but also wildlife and pets. For humans, exposure can lead to various health issues, ranging from mild irritations to severe illnesses, depending on the type and amount of pesticide involved. Non-target organisms, like beneficial insects (such as pollinators), birds, and aquatic life, can also suffer detrimental effects from pesticide exposure, affecting their health, reproduction, and survival.

In the context of the other options, the increased sale of pesticide products is not directly related to the risks posed by drift; it focuses more on market dynamics than health or environmental impacts. Genetic resistance in pest populations, while a significant issue in pest management, is typically a consequence of pest exposure to pesticides over time, rather than a direct risk stemming from drift. Improved crop yield is an outcome that is generally desired from proper pesticide use, but it is irrelevant in the context of risks associated with drift, which primarily concern health and ecological safety.
