Good morning respected teachers and my dear friends. On the occasion of World Enviroment Day, I would like to talk about the growing enviromental changes and concerns of today's world.
Pollution is a global threat today. While a lot of scientists have highlighted the dangerus effects of deforestation and pollution and changing global climate, we are doing very little to save the situation. Without conserving forest and being a little more responsible about the pollution, we will soon lose the world. I urge all my friends and teachers on the occasion of World Environment day, plant more trees around our school and our homes. And be more vigilant about their practices which can affect the environment.
We have inherited this beautiful planet from our forefathers and we have the responsibility to pass it on to our children without making it dangerous.
Plant More Trees Around Schools and Homes
Good morning everyone present. I feel immensely privileged to have got the opportunity to express my views on ‘Trees are Our Lifeline’. Franklin D. Roosevelt rightly said, “A nation that destroys its soils destroys itself. Forests are the lungs of our land, purifying the air and giving fresh strength to our people. ” Trees are indispensable for life. Man can’t live without trees.
However, the present condition of forests in the world, especially developing countries is pathetic and miserable. Forests 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.
Most of the world oxygen that the animal species including man inhale is produced in the forests and tropical rainforests. Forests and rainforests house millions of species of plants, animals and insects. Even more importantly, they are home to many unique plants and animals that do not exist anywhere else in the world. If the tropical rainforests were to be destroyed, so would the homes of all these species. Without a home, many of these species could become extinct.
Trees are important to the environment; they recycle water and process carbon dioxide in the atmosphere through photosynthesis. They are the world's full-time 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.
Cutting of trees will have a negative effect on the environment. It will result in an increase in the amount of carbon and other greenhouse gases in the environment. Burning of these forests will result 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 are known to 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.
Extreme weather conditions, changing agricultural production, and increase in the disease carrying viruses are some of the other effects of global warming. Deforestation is the primary reason behind global warming; we need to show greater concern towards the cutting of trees on a large scale. We need to take quick measures for preventing deforestation of the tropical forests so that we can hope for an environment that is healthy to live in.
So, we see how crucial trees are for evolution and the smooth running of all the life forms on the planet. They are indeed the power-house of evolution. It is our bounden duty to plant and preserve trees and forests as without them we can’t exist.
The number of trees required to supply fresh air around our schools and homes has gone below the minimal level. It means the air we are breathing in cities and towns is highly polluted. It will kill us. Let’s stop this poisoning by planting as many trees around our homes and schools as is possible. Each student must take active part in this tree plantation and looking after them.
Thank you.
