Speech on reasons for global warming and adverse effects of it
Answers
Good morning to my respected teachers and my dear friends. Now-a-days, every one of us is well aware of the threat of climate change. It is a serious issue increasing continuously because of the global warming. It is a big issue for our future generations to face all the challenges of this irreversible catastrophe changes in the environment. Global warming is the regular increase in atmospheric temperature of the earth. Earlier the rate of rise in temperature was slow however currently it is going at a faster rate. The main causes of the global warming are green house gases such as nitrous oxide, carbon dioxide, methane, etc. Such gases gets collected in the atmosphere and trap heat from all resources like sun and heat created by human activities (burning fossil fuels, petroleum, deforestation, etc). Global warming affects our planet atmosphere in many ways.
Because of increasing temperature in the environment, the arctic glaciers start melting and threatening the life of polar bears. Melting glaciers creates lots of water which increases sea levels in the low land areas of South Sea Islands. Increasing ocean temperatures creates problems to the life of plants and animals of water causes algae to die and disturbs entire food chain. In order to lessen the side effects of the global warming many laws have been made and implemented by the government of various countries such as limiting the harmful vehicle emissions, reducing emissions of chemicals causing damage to the ozone layer, reducing plant cutting, inducing tree planting, car pooling, etc.
We should change our habits positively in order to reduce waste by choosing the use of reusable products instead of disposable one. We should buy products having minimal packaging to reduce amount of wastes. We should recycle paper, newspaper, glasses, aluminium cans, etc. If we start recycling at least half of your household wastes, we can save approximately 2,400 pounds of carbon dioxide emission every year. We should reduce the need of electric use such as air condition, hair drier, room heater, etc. We should make the habit of turn down lights while sleeping at night or day when we go outside. We should replace our regular bulbs with the compact fluorescent light (CFL) bulbs. Regular use of the CFL instead of regular light bulbs would help in eliminating around 90 billion pounds of greenhouse gases from the atmosphere.
We should try to drive less and in very smart way for the fewer harmful gas emissions. We should try to walk by foot as much as possible instead of using bike, car or other means of transport. We should reduce our hot water use and try to use cold water as much as possible. In this way by reducing our electricity use we can reduce the global warming. Together with changing our own habits, we should encourage others to conserve energy by reducing lights use as much as possible.
Thank You
