Answer to Question 1

Ans: A
Health hazards to humans from ionizing radiation include birth defects; increased rates of cancer, stroke, diabetes, cardiovascular, renal disease; and immune system damage. Nonionizing radiation leaks from microwave ovens that have improperly fitted seals can cause fatigue and headache.

Answer to Question 2

Ans: B
Deforestation is the clearing of forests to create crop lands. Deforestation contributes to soil erosion, a change in climatic conditions, and air pollution. Climate changes result in increased desertification. A loss of biodiversity results in the extinction of certain species of plants and animals and thus deforestation, desertification, and reproductive changes. There has been an overall increase in temperatures throughout the world. The greenhouse effect is a contributing factor to global warming.
