Which of the following would be an environmental impact of high density animal farming?

• livestock can escape

• water pollution due to runoff

• the concern about safety to consume

• they can cause food allergies

When irrigation water evaporates, salts are left behind on the soil surface and can cause plant death or lead to

• soil salinization

• desertification

• waterlogging

• monocropping

What is a natural part of a forest ecosystem and may be required for seed germination?

• floods

• tornadoes

• fire

• polar vortex

Use of this method of control requires concentrations to be increased often because pest develop resistance

• GMOs

• control burning
