Question

why is the pesticide treadmill problematic? farmers must decrease the amount of pesticide next time they spray for pests. farmers must increase the amount of pesticide the next time they spray for pests. farmers can never change pesticides once the treadmill is activated. farmers must always use the same pesticides as every other farmer on the treadmill.

Explanation:

The pesticide treadmill refers to the cycle where pests develop resistance to pesticides, so farmers need to use more (higher dosage or more toxic) pesticides in subsequent applications to control pests. Let's analyze each option:

• Option 1: The pesticide treadmill leads to needing more, not less, pesticide, so this is incorrect.
• Option 2: As pests develop resistance, farmers have to increase pesticide amounts to achieve the same pest control, which is the core of why the pesticide treadmill is problematic.
• Option 3: Farmers can change pesticides (e.g., switch to a different chemical class), so this is false.
• Option 4: Farmers don't have to use the same pesticides as others; they can choose different ones, so this is incorrect.

Answer:

B. Farmers must increase the amount of pesticide the next time they spray for pests.
