Essay 1 (100 words)Why do you think temperature goes too high in summers and too low in winters? Well, it is a phenomenon known as Global Warming.Global Warming is nothing but the elevation in the temperature of Earth’s surface. Here, the Earth’s surface comprises both land and water which means that the temperature of not only land increases but that of water as well. Such heat in the atmosphere creates many problems for plants, animals and human beings on Earth. Global Warming is majorly the result of increased Greenhouse effect. Because of this phenomenon, the water level of both sea and ocean has increased. Such a rise in water level is unwanted as it can even result in a natural calamity like a flood. To prevent such natural disasters some serious measures are required to be taken so as to save our planet Earth.Essay 2 (200 words) There are so many human activities which have created problems in the environment out of which one is Global Warming. It is that phenomenon which is a result of various aspects like factories, harmful chemicals, greenhouse gases, pollution, cutting down of forests etc.What is Global Warming?In the simplest words –it is the heating up of the atmosphere of Earth due to non-stop rise in temperature. The main cause of temperature rise is greenhouse gases..How Global Warming takes place?Global Warming happens because the amount of greenhouse gases like Carbon dioxide, Nitrous Oxide, Methane, etc has increased largely since last few years. These gases in the atmosphere soak up heat and increase the temperature which is known as greenhouse effect. This heat creates problems for all the living beings (plants, animals and humans).The greenhouse effect is necessary also because it keeps the Earth warm which makes life possible else Earth would freeze. But because of increasing greenhouse effect –Global Warming is taking place. What does Global Warming lead to?1. High sea and ocean level.2. Destroying aquatic life.3. High Temperature.4. Extreme Weather.5. Melting of Ice and Glaciers.Easy prevention steps to reduce Global Warming?1. Forestation.2. Decreasing the use of hazardous chemicals.3. Using public transport.4. Using wind and solar energy.Global Warming is a very serious topic that can create very big problems for all the living beings on Earth. Hence, everyone needs to come together and try their best to prevent Global Warming.
