Global Warming Speech

Good morning to my respected teachers and dear friends. I would like to speech on the Global Warming at this occasion. Global warming is a continuously increasing environmental issue all over the world. There is no any single country responsible for its causes, all the countries worldwide are responsible for its ever increasing. Actually global warming is a global increase in the temperature of the earth because of our some daily activities. Our various activities heats up the earth which ultimately rises its temperature. Rise in temperature takes place when greenhouse gases (such a carbon dioxide, water vapours, nitrous oxide, methane, etc) trap heat and light from our surroundings and sun. Ultimately, rise in temperature hurts the lives of human beings, animals, and plants. There are many reasons for the increasing global warming however some of the primary and main causes are considered because of the Green House Effect.

Green house effect is caused by the green house gases carbon dioxide, chloro-fluoro carbon, methane, nitrous oxides, etc gases. Such green houses gases are generated by our daily activities and get collected in to the atmosphere and form a cover around the Earth which again absorbs hot sun rays and make this earth a burning earth. The absorbed heat remains in the lower circle of biosphere and enhances the temperature level. According to the statistics it has been estimated that by 2050 the rise in temperature of earth would be about 4° to 5°C. In last five centuries, it has raised by about 1°C however half of this warming is raised only during twentieth century. So, the global warming is at peak and alarms us regularly with its bad effects.

It is affecting almost all parts of the world and causing sea level to rise, glaciers to melt and many more which covers all the low land islands. It is destroying huge forests, killing algae, acid rain, etc. Acid rain is very dangerous which may destroy anything in touch. Global warming causes natural fires which may wipe out whole forests. Continuous rise in the earth temperature affects agricultural crops, forests, marine life and life growth on the earth. It cannot be solved by the effort of only one country, it needs global effort of all countries to reduces its effects and completely eliminate it.

Thank You

Environment is Life
-----------------------------

Environmental pollution is the destruction of the environment. That is, the means of which our environment is corrupted due to which our environment is corrupted. Before this, due to its impact on humans and the natural world, we have to know and understand about it.

Main types of environmental pollutants - air pollution, water pollution, noise pollution, thermal pollution, soil pollution and light pollution. Gradually the population of the world is growing, due to which people are cutting forests to make homes. Due to deforestation in these past 10-15 years, there have been many types of hazardous gas emissions in the earth.
We live in such a beautiful planet Earth, the only planet where there is environment and life. One of the best ways to keep the environment clean is to keep water and air clean. But in today's day, man has been doing all his work on the contrary, whose biggest pollution is in front of our eyes.

We have to understand that if we want to save the earth, then we have to take stern steps so that we can save our environment from contamination. Without water and air the life of life will end in the earth so it is very important to keep these things in balance.

The Earth biosphere is a mixture of many types of oxygen, nitrogen, carbon dioxide, argon, and steam. All these things are very important for all the living beings. We have to keep the environment in accordance with the law to give the earth beautiful, clean and a better life for human beings. But the way human beings are flirting with nature, its hope is very little visible.
