Answer to Question 1

True

Answer to Question 2

Many farmers worldwide report both financial and conservation benefits from planting genetically engineered crops. Growing herbicide-resistant crops, for example, requires less tilling of the soil to reduce weed growth, decreasing soil loss from wind and water erosion. Pesticide-resistant crops demand less use of both petroleum-based pesticides and the fuel to run the equipment to apply them. Salt-resistant crops can grow in salty areas where conventional crops wither. If approached carefully, genetically engineered plants and animals promise economically feasible, environmentally less destructive options for agricultural lands.
