Multiple choice

What can be done to protect coral reefs?

  1. Reduce greenhouse gas emissions

  2. Reduce pollution

  3. Reduce overfishing

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above actions are necessary to protect coral reefs. Reducing greenhouse gas emissions will help to slow the rate of climate change and reduce coral bleaching. Reducing pollution will help to improve water quality and reduce the amount of nutrients that can feed algae. Reducing overfishing will help to maintain the balance of the ecosystem and prevent the spread of algae.

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Travel literature that explores the concept of 'rewilding' primarily focuses on promoting the restoration of natural ecosystems, encouraging people to reconnect with nature, and educating readers about the importance of biodiversity.

Multiple choice

What can be done to prevent coral bleaching?

  1. Reduce greenhouse gas emissions

  2. Protect coral reefs from pollution

  3. Limit overfishing

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

To prevent coral bleaching, it is important to reduce greenhouse gas emissions, which contribute to climate change and rising water temperatures. It is also important to protect coral reefs from pollution, which can make them more susceptible to bleaching. Finally, it is important to limit overfishing, as this can reduce the number of fish that eat algae, which can lead to an increase in algae growth and competition for space on coral reefs.
