Trees reduce the urban heat effect and ozone formation in the troposphere besides providing shades during hot summer days and helping mitigate urban noise pollution.
The event was held at the Chemistry Auditorium on Friday. The Departments of Chemistry, Education, and Botany of the University of Karachi jointly organized the seminar. They later had a plantation activity and a poster competition for students at the botany department.
He informed the audience that the timber mafia had been relentlessly cutting down, but unfortunately, no serious action has been taken against them yet. He said that, like other plants, these two trees also absorb carbon dioxide and provide oxygen and do not have any adverse effects on the environment.
"One of the major reasons for the rapid temperature rise is the relentless deforestation. We should focus on planting different types of plants instead of the same type of plants as plantation of one type of tree could be dangerous, as diseases can rapidly affect all of them. In contrast, if we have a variety of plants available, then it will take some time to damage them."
Another speaker, Dr Hina Baig from the National Institute of Oceanography, said that we are working to eliminate marine pollution. We all need to work together to eradicate marine corruption and protect aquatic life.
"Every year, millions of aquatic life die due to garbage dumping. There is a need to raise public awareness in this regard. People need to understand how much damage is done to the garbage thrown into the sea."
On this occasion, Dr Dilshad Ahmed of Sindh Environmental Protection Agency said that every year various events related to the world environment are organized by the public and private sectors but, unfortunately, we do not implement what we learned from such events, and that is why we have failed to produce fruitful results so far. He urged that people should take care of plants as it is necessary for the better future of our next generation.
