Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
