ADMT Lesson 1 Environment- Hakeem
Will human beings' selfish acts bring about the Earth's doom?
It will, eventually. Mankind has been emitting harmful gasses through factories, vehicles, the burning of rubbish and so on.
Human beings also cut down forests for paper which means we have more paper but we compromise on the amount of carbon dioxide in the air. Plats take in carbon dioxide and release oxygen. In the end we will be left with no more forests unless necessary actions are taken. If we have no more trees, we will have less oxygen to breathe and we will die. There will be more carbon dioxide in the air so more heat will be trapped and Earth will get warmer and warmer. Polar ice caps will melt faster and low lying islands will be flooded and sink. Also, when we cut down trees, we expose the soil that it holds and this results in soil erosion, which means that no plant can grow on it.
When factories release harmful gasses and chemicals into the atmosphere, it dissolves into the water droplets and results in acid rain, which can destroy and damage buildings and structures.
Through vehicles, carbon dioxide is released and gathers in the atmosphere. This is a major hazard where there are many cars and people, for example, in China. People, especially, children and the elderly are vulnerable to the carbon dioxide and other harmful gasses which could lead to breathing problems and death. An increase in the amount of carbon dioxide means more heat is trapped and this results in global warming. Polar ice caps will melt faster and low lying islands will be flooded and sink.
What can we do to save the Earth?
We can reduce the amount of paper we use, in other words, save paper and recycle it, including cans, plastic bottles and so on. We could also reuse the water we use for cooking to wash the toilet or plants. We could also recycle paper plastic and cans so new ones need not be manufactured and so we save our resources.
