Question
Read the following statements:
Statement 1: We should use plastic bags more and more.
Statement 2: We should allow stagnated water to stand.
- Only statement 1 is correct.
- Only statement 2 is correct.
- Both the statements are correct.
- Both the statements are incorrect.
Hint:
Plastic bags are harmful for nature and amount of nutrition decreases in the stagnant water.
The correct answer is: Both the statements are incorrect.
- In the above question, both statements 1 and 2 are wrong.
- We should not use plastic because plastic is a non-biodegradable material that takes millions of years to decompose. It also releases toxic gases when burned. Thus, the usage of plastic should be minimum.
- Stagnant water should not be allowed to stand because algal blooms are very common in stagnant water. These algal blooms deprived the aquatic organisms of nutrients thus, causing the deaths of the said organisms.
