1 In order to keep up with the food demands of an increasing human population, farmers use fertilizers and other agricultural
technologies to grow and harvest more food. How do fertilizers negatively impact

the environment?
OA. The rate of nutrient depletion increases in soil that has been fertilized.
OB. Run-off from fertilized land increases nitrogen levels in ecosystems and encourages algal growth.
OC. Fertilizers are difficult to apply and require heavy machinery which damage land.
OD. Fertilizers allow crops to grow bigger and faster, so they can feed more people.
