What is the primary cause of environmental health problems?
-
Pollution.
-
Climate change.
-
Deforestation.
-
All of the above.
D
Correct answer
Explanation
Pollution, climate change, and deforestation are all major causes of environmental health problems. Pollution can contaminate air, water, and soil, which can lead to a variety of health problems. Climate change can lead to extreme weather events, which can cause injuries and deaths. Deforestation can lead to soil erosion, which can pollute water sources and contribute to climate change.
What is the primary cause of water pollution?
-
Industrial waste.
-
Agricultural runoff.
-
Sewage.

All of the above.
D
Correct answer
Explanation
Industrial waste, agricultural runoff, and sewage are all major sources of water pollution. Industrial waste can contain toxic chemicals that can contaminate water sources. Agricultural runoff can contain pesticides and fertilizers that can pollute water sources. Sewage can contain bacteria and viruses that can contaminate water sources.
What is the primary cause of soil pollution?
-
Industrial waste.
-
Agricultural chemicals.
-
Mining.
-
All of the above.
D
Correct answer
Explanation
Industrial waste, agricultural chemicals, and mining are all major sources of soil pollution. Industrial waste can contain toxic chemicals that can contaminate soil. Agricultural chemicals can contain pesticides and fertilizers that can contaminate soil. Mining can release heavy metals and other toxic chemicals into the environment.
