Question

Write a essay on global warming. (150 words).

Answer 1

Global warming is a big issue of the atmosphere on the earth which cause continuous rise in the surface temperature of the Earth. It has been estimated that in next 50 or 100 year the temperature of earth would be increased to a great level which would create big problem of living on earth. The highly known and most basic cause of increasing the Earth’s temperature is continuous rise in the atmospheric carbon dioxide.Rise in the carbon dioxide level is the use fossil fuels like coal and oil, deforestation (cut down of plants) by the human beings on Earth. Decreasing number of the plants on the earth increases the level of carbon dioxide, as plants are the main source of the using carbon dioxide released by the human being (as a by-product of respiration) and other means. Increasing level of Earth’s temperature creates lots of problems like sea level becomes hotter and higher, glaciers melt, flood, strong storms, lack of food, diseases, death, etc.

Answer 2

Answer:

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 and 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. 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.

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.
