Sir: The ratio of deforestation is quite higher than plantation in our country which is food for thought. There was a time when there were plants planted inside and outside residential houses especially in Karachi and there were some areas where old trees planted but such old trees were cut owing to few reasons like carpeting of new roads or some other constructions like building a bridge or under passes. If there was need to cut such old trees coming on the way of construction, new plants should have been planted so that greenery should remain intact in the city but this was not the case and these days Karachi’s most areas are deprived of old trees and new/old plants inside and outside houses. Plants are good for human health as plants absorbs carbon dioxide and excrete oxygen while human being does vice versa ultimately plants keep human being healthy. Concerned authorities should make sure that if any old tree is cut owing to any reason anywhere in the country, an alternate plant should be planted. Moreover, awareness campaign should be initiated across country about the advantages and disadvantages of deforestation and plantation. A greater emphasis should be given to plant more and more trees and avoid cutting any old plant and tree. FAISAL ANSAR Karachi Published in Daily Times, March 17th 2019.
