pls give me debate in favour of afforestation need of today era

Good morning everyone present. I stand in front of you to express my views on ‘afforestation need of the modern era’ and I am going to speak in favour of it. Franklin D. Roosevelt rightly said, “A nation that destroys its soils destroys itself. Trees and forests are the lungs of our land, purifying the air and giving fresh strength to our people. ” The present condition of trees and forests in the world, especially developing countries is pathetic and miserable. Trees are the source of life. They are the giving angels. They give man oxygen, rains, wood, fruit, make the world look so beautiful, yet the sinister man kills them! Who will be more inhumane than man himself? Cutting of forests ultimately endangers man’s own existence.
Without tress all species of animals and plants will die. They are the oxygen generators of the world that the animal species including man inhale and thus are able to live. Millions species of plants, animals and insects live in the tropical rainforests. They are important to the environment as they recycle water and regulate levels of carbon dioxide in the atmosphere through photosynthesis. They are the world's heavy-duty purifiers of air and water. Their cutting will disturb the natural water cycles which will lead to the shortage of fresh-water in the water reserves of the world.
Owing to industrialization and urbanization large scale cutting of these trees has had a negative effect on the environment. It has resulted in an increase in the amount of carbon and other greenhouse gases in the environment. Burning of these forests has resulted in the emission of a large amount of carbon dioxide into the air. Carbon dioxide and other greenhouse gases like the oxides of nitrogen and methane trap atmospheric heat, thus increasing the average temperature of the Earth's surface. This increase in the temperature near the Earth's surface and oceans is termed as global warming.
I strongly feel afforestation is the only panacea to the problems caused by pollution and global warming. Afforestation is the most efficient natural technique to minimize greenhouse effect. Trees will reduce the excess of carbon dioxide by processing it during the photosynthesis. Apart from this, trees will preserve wildlife, beautify and purify the surroundings, minimize soil erosion, stabilize climate, provide forest products for growing human population, construction, and infrastructure.
Advanced countries have already started mass afforestation drives in their cities. Geneva, Amsterdam, New York, Sydney, Boston, Miami, Toronto, Frankfurt, etc have become ideal cities by planned afforestation across them. We should also plant tress in cities as well as create green belts around them. We must remember we have the responsibility of providing a better future and environment to coming generations.
All of us must plant at least one tree each, and ensure they grow into full trees. It will be the most positive and constructive step towards environment conservation and ensuring peaceful, healthy, and prosperous life for the coming generations.
