Which of the following is NOT a consequence of soil pollution?
-
Reduced Soil Fertility
-
Contaminated Crops
-
Increased Soil Biodiversity
-
Groundwater Contamination
C
Correct answer
Explanation

Which type of marine debris poses the greatest threat to marine life?
-
Plastic debris
-
Metal debris
-
Glass debris
-
Paper debris
A
Correct answer
Explanation
