Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fishing nets, particularly discarded or lost fishing gear, are often found entangled around marine animals, such as sea turtles, dolphins, and whales, causing injury, entanglement, and sometimes death.

Multiple choice

What is the primary cause of ocean acidification?

  1. Increased Carbon Dioxide Levels

  2. Oil Spills

  3. Overfishing

  4. Coastal Development
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ocean acidification is caused by the increased absorption of carbon dioxide from the atmosphere by the ocean. This leads to a decrease in the pH of the ocean, making it more acidic. Ocean acidification has various negative impacts on marine life, including reduced calcification and increased susceptibility to disease.

Multiple choice

What is the primary source of nitrogen pollution in urban runoff?

  1. Animal waste

  2. Synthetic fertilizers

  3. Atmospheric deposition

  4. Septic tank leakage
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atmospheric deposition is the primary source of nitrogen pollution in urban runoff. Nitrogen oxides from vehicle exhaust and industrial emissions can be deposited on surfaces and washed off by rain, contributing to nitrogen pollution in urban waterways.
