Which one of the following is a threat to the environment?a.Growing plantsb.Growing populationc.Growing cropsd.Growing owers

The answer is b. Growing population.

Here's why:

a. Growing plants - This is not a threat to the environment. In fact, it's beneficial as plants absorb carbon dioxide, a greenhouse gas, and release oxygen.

b. Growing population - This is a threat to the environment. A larger population means more resources are needed, which can lead to overexploitation. It also means more waste is produced.

c. Growing crops - This is not inherently a threat to the environment, though certain farming practices can be harmful. However, in the context of this question, it's not the correct answer.

d. Growing flowers - Similar to growing plants, this is not a threat to the environment.
