Question

"Vanishing Greenery; A Growing Urban Crisis" In most of our cities, rapid urbanisation has led to a significant decrease in greenery over the past two decades. As the population increased, the demand for housing, roads and commercial buildings grew, leading to clearing of parks, gardens, and natural resources. This has contributed to several problems. 

(a) Mention one significant problem caused by the reduction in urban greenery.
(b) How do green plants contribute to improving the air quality?
(c) What role can you, as a citizen, play in protecting urban greenery?

 

Hint:

Urban greenery helps in reducing pollution, maintaining biodiversity, and improving mental health. Citizens play a key role in preserving and expanding green spaces through collective action and awareness.

Answer 1

(a) Mention one significant problem caused by the reduction in urban greenery. 
One significant problem caused by the reduction in urban greenery is increased air pollution. The reduction of trees and plants decreases the ability of the environment to absorb pollutants like carbon dioxide, leading to poorer air quality and contributing to health problems for the population. (b) How do green plants contribute to improving the air quality? 
Green plants improve air quality through a process known as photosynthesis. During photosynthesis, plants absorb carbon dioxide from the air and release oxygen. This helps in reducing the amount of harmful gases in the air, thus improving air quality. 
(c) What role can you, as a citizen, play in protecting urban greenery? 
As a citizen, you can contribute to protecting urban greenery by participating in tree planting initiatives, avoiding littering, and supporting policies that promote the conservation of parks and green spaces. Additionally, you can spread awareness about the importance of greenery and advocate for its preservation.
