The main cause of soil salinization from irrigation Accumulation of salts in the soil from
evaporation of ground water from excessive irrigation
Arguments for pesticide use Saving lives, increase crop yields and profits for farmers
Arguments against pesticide use Harmful to wildlife and the environment, pesticide use is
linked to cancer
Pesticides that don't break down easily and become concentrated in the water and soil and
organisms high on the food chain Persistent pesticides
Uses for genetically modified organisms Adding nutrients and vaccines to crops, drought
resistant crops, parasite resistant crops
Benefits for GMOs Less expensive and takes about half the time versus artificial selection
Agriculture focusing on the farm as an ecosystem that selects productive, pest resistant crops that
require few resources Sustainable agriculture
How is compost beneficial? Waste, such as manure and rotting plants, can be added to soil
for nutrients instead of sent off to the landfill
Reasons the Green Revolution were not entirely positive Use of pesticides and fertilizers
increased the risk of pollution
