Answer 2

Answer:

Respected Principal, teachers and my fellow students. This morning, I am going to speak on Global Warming, which is not only making life difficult but threatening the existence of life on Earth.

Global Warming

Global warming is the phenomenon of the increase in the temperature of the atmosphere due to the presence of excessive greenhouse gases emitted mostly by the burning of fossil fuels.

Effects of global warming:

Global warming will results in the melting of the polar ice caps and raise the ocean level which will submerge islands and coastal lands. Island nations which will be submerged first by the rising sea level are the Maldives, Solomon Islands, Samoa, Fiji Islands, etc.

Due to extreme climatic conditions, millions of people will be displaced. There will cause a serious refugee problem as people migrate to other countries looking for resettlement.

Global warming would cause unpredictable rainfall. A sudden flash flood will be followed by a long period of drought. This will cause scarcity of drinking water and irrigation for cultivation leading to worldwide food scarcity.

The burning of fossil fuels increases global warming and also depletes the ozone layer which protects us from the harmful effects of UV rays of the Sun. This will increase the cases of skin cancer.

Global warming would cause unpredictable rainfall. A sudden flash flood will be followed by a period of a long drought. This will cause a scarcity of drinking water. The shortage of water for irrigation will lead to the failure of agriculture and cause worldwide food scarcity.

Prevention of Global Warming:

The catastrophic consequences of Global Warming can be mitigated by preserving the natural ecological system, shifting to sustainable development, and using more environmentally friendly energy.

Planting more trees will reduce the amount of harmful carbon dioxide gas in the atmosphere and reduce global warming. We need to shift to alternative energy instead of burning fossil fuels like coal and petroleum products.

Industrial waste must be treated properly before they are dumped. Using renewable energy like hydroelectricity and solar energy will help us to reduce global warming. Urgent steps must be taken to reduce exhaust emissions from motor vehicles, power plants, factories, and industries. Global warming needs urgent global actions for the survival of life on earth, our home planet.

Thank you.
