-
Industrial waste
-
Agricultural runoff
-
Sewage discharge
-
Oil spills
B
Correct answer
Explanation
Agricultural runoff, containing fertilizers, pesticides, and animal waste, is the primary cause of water pollution.
Which human activity is the primary cause of plastic pollution?
-
Industrial waste
-
Consumer products
-
Agricultural runoff
-
Oil spills

Which of the following is a major environmental impact of rice cultivation?
-
Deforestation
-
Water pollution
-
Greenhouse gas emissions
-
All of the above
D
Correct answer
Explanation
Rice cultivation can lead to deforestation, water pollution, and greenhouse gas emissions. Deforestation occurs when forests are cleared to make way for rice paddies. Water pollution occurs when fertilizers and pesticides used in rice cultivation run off into waterways. Greenhouse gas emissions occur when rice paddies release methane, a potent greenhouse gas, into the atmosphere.
What is the primary environmental concern associated with hydropower?
-
Greenhouse gas emissions
-
Habitat fragmentation
-
Water pollution
-
Deforestation
B
Correct answer
Explanation
Hydropower dams can block fish migration routes and fragment aquatic habitats, leading to a decline in biodiversity.
Which of the following consumer products is commonly associated with heavy metal pollution?
-
Batteries
-
Electronic devices
-
Cleaning products
-
Personal care products
A
Correct answer
Explanation
Batteries, particularly those containing lead, cadmium, or mercury, are known to contribute to heavy metal pollution when improperly disposed of or recycled.
What is the primary environmental concern associated with the use of plastics in consumer products?
-
Greenhouse gas emissions during production
-
Pollution of water bodies due to microplastics
-
Depletion of non-renewable resources
-
All of the above
D
Correct answer
Explanation
The use of plastics in consumer products raises concerns about greenhouse gas emissions during production, pollution of water bodies due to microplastics, and the depletion of non-renewable resources.
