200 Words – Essay on Greenhouse Gases and their Emissions for Kids & Students in Very Easy Words

Greenhouse gases are gases in the atmosphere that absorb and re-emit radiant energy within the thermal infra-red range. The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the absence of greenhouse gases, the average surface temperature of the Earth will decrease to 18 ° C instead of 15 ° C.

Atmospheric concentrations of carbon d-oxide 1750 a. D. Has increased by 40%, from 280 ppm to 406 ppm. This increase has been reported even after more than half of the carbon d-oxide was absorbed by natural sinks. Most human-induced carbon dioxide emissions come from the combustion of fossil fuels, mainly coal, petroleum oil, and natural gas, with additional contributions coming from deforestation.

If greenhouse gas emissions continue at their current rate, Earth’s surface temperature is expected to rise to unpredictable values ​​in early 2047, with potentially damaging effects on ecosystems and biodiversity, including the livelihoods of people around the world. It is feared that the Earth may cross the 2 ° C global warming threshold at the current emission rate, which the United Nations IPCC has designated as the upper limit to avoid the dangers of global warming by 2036.

Any gas that allows solar radiation from the Sun to come to Earth, but absorbs longitudinal radiation from the Earth and raises the Earth’s temperature, is called greenhouse gas. Currently due to humanitarian reasons, the increasing amount of greenhouse gases in the atmosphere has become the cause of global warming and climate change. If their quantity is not controlled, it will prove fatal to humans as well as the entire world.

The phenomenon of greenhouse gases present in the earth’s atmosphere due to absorption of heat emitted from the earth and increase in atmospheric temperature is called greenhouse effect. In fact due to the occurrence of the greenhouse effect, the temperature on the Earth is controlled and plants and animals get the heat needed for their growth. Greenhouse gases have a direct impact on the Earth’s atmosphere, as these gases act as blankets for the Earth.

Naturally occurring greenhouse gases in the atmosphere are gases containing CO2, CH4, N2O and fluoride. Whereas chlorofluorocarbons, hydro fluorocarbons and fluorocarbons sulfur hexachlorides are greenhouse gases synthesized by human activities. These greenhouse gases are not only responsible for global warming, but they have also depleted the ozone layer. The ozone layer has a lot of free space from where the sun’s UV rays directly reach the Earth causing great harm to flora and fauna.

The main reasons for the increase in greenhouse gases are industrialization, urbanization, destruction of forests and smoke from fossil fuels burning in homes and industries. But in the 19th and 20th centuries, the amount of greenhouse gases emitted from human activities in the atmosphere increased, resulting in an increase in the amount of greenhouse gases in the atmosphere. This results in global warming and other climate changes.

The greenhouse effect is a natural phenomenon and is important for life. The Earth’s average temperature without the greenhouse effect would be -180C, instead of the current average temperature of 150C. However, the problem arises when the atmospheric concentration in greenhouse gases such as CO2, CH4, N2O, O3 halocarbons and water vapor increases.

Importance of Green House Effect

The greenhouse effect maintains a balanced temperature on the Earth’s surface, causing humans, plants and animals to survive. It acts like a reflector that sends harmful rays coming from the sun back into space. The ozone layer reflects the sun’s U-V rays, absorbing carbon dioxide and other gases with long-wavelength radiation. Without this effect, it would be impossible to avoid the harmful effects of radiation coming from the sun. In general, the balance of these gases plays a very important role in driving the cycle of the environment.

Effects of emission of greenhouse gases

The environment has been continuously polluted in the last decade due to man-made uncontrolled industrialization, unplanned urbanization, population growth and many other activities. Currently, the amount of carbon dioxide in the atmosphere has increased by about 31 percent above normal due to indiscriminate congestion to meet the requirements, causing more heat to be absorbed into the lower atmosphere, a gradual increase globally. . Warming by inhibiting the cohesion of greenhouse gases.

How to reduce emissions

Reduction in emission of greenhouse gases is difficult but not impossible. A large number of international and national level institutions are working on it. Some important facts by which its emissions can be reduced, such as-

  • Energy efficiency must increase in consumption and production.
  • There should be complete combustion of fuel in vehicles which is possible with proper maintenance.
  • Use of new sources of energy such as solar energy, hydropower, nuclear power etc.
  • The removal of toxins from industries should be minimized.
  • Reducing the production of halocarbons such as fridges, air conditioning, cyclic chemicals.
  • Afforestation should be encouraged.
  • Seaweeds must be grown so that carbon dioxide can be used through photosynthesis.

The conclusion

In the end, it can be said that if humans do not make the necessary arrangements to control the emission of greenhouse gases, the earth will face the problem of heating and it will be unbearable to live in such adverse condition after few years or decades. .

Any gas that allows solar radiation from the Sun to come to Earth, but absorbs longitudinal radiation from the Earth and raises the Earth’s temperature, is called greenhouse gas. Currently due to humanitarian reasons, the increasing amount of greenhouse gases in the atmosphere has become the cause of global warming and climate change.

If their quantity is not controlled, it will prove fatal to humans as well as the entire world.

Green House Effect

The phenomenon of greenhouse gases present in the earth’s atmosphere due to absorption of heat emitted from the earth and increase in atmospheric temperature is called greenhouse effect. In fact due to the occurrence of the greenhouse effect, the temperature on the Earth is controlled and plants and animals get the heat needed for their growth.

Greenhouse gases

Greenhouse gases occur naturally in the atmosphere:

  • Carbon dioxide (CO2) is the most prominent greenhouse gas
  • Methane (CH4)
  • water vapour
  • Nitrous oxide (N2O)
  • Fluoride gases

The following are greenhouse gases produced or synthesized by humans:

  • Chlorofluorocarbons (CFCs)
  • Hydro fluorocarbon (HFC)
  • Fluorocarbons’ (PFCs)
  • Sulfur hexachloride (SF6)

Effect of greenhouse gases

Greenhouse gases have a direct impact on the Earth’s atmosphere, as these gases act as blankets for the Earth. If these gases are not present and they do not absorb heat, the Earth will cloud into a cold planet and human life will not be able to live in its present form.

But in the 19th and 20th centuries, the amount of greenhouse gases emitted from human activities in the atmosphere increased, as the amount of greenhouse gases in the atmosphere increased. This results in global warming and other climate changes. Global warming refers to an increase in the Earth’s long-term average temperature.

Causes of emission of greenhouse gases

The following are the major reasons for the increase in greenhouse gases:

  • Industrialization
  • Urbanization
  • Consumerist culture
  • Smoke from burning fossil fuels in vehicles
  • Destruction of forests

Measures to reduce the emission of greenhouse gases

Today it is necessary to control the amount of greenhouse gases in the atmosphere by reducing the emission of greenhouse gases, so as to avoid the side effects of global warming. Following are the measures to reduce the emission of greenhouse gases:

  • Renewable and less polluting energy sources should be used more.
  • Consumption of greenhouse gases such as televisions, refrigerators, air-conditioners, etc. should be used sparingly.
  • Use fewer vehicles or use less polluting fuels such as CNG in vehicles.
  • Afforestation should be encouraged, as trees absorb greenhouse gases such as carbon dioxide.
  • Energy must be used judiciously and continuously.

The conclusion

On September 15, 2009, the World Bank released the World Development Report on Development and Climate Change in a report on September 15, 2009, reducing greenhouse gas emissions from developed countries and providing related funding and technical assistance to developing countries Asked for The report warns that the question of climate change should not be ignored amid the current financial crisis.

The greenhouse effect is a process in which some gases enter the atmosphere and cause the Earth’s temperature to rise. As a result, the Earth’s average temperature rises, which is a concern. At the present time the term ‘greenhouse effect’ is used for the worldwide problem which is the cause of temperature rise, which is the cause of climate change and which is the cause of crisis for the ecosystem.

The greenhouse effect refers to the change in temperature of the earth due to the presence of certain gases. The atmosphere acts as a shield on the Earth and protects life on Earth from harmful rays of sunlight. Various agents around the Earth absorb the sun’s heat with dust particles, water vapor, water clusters, ice, land, etc., but when their balance is interrupted, the temperature starts to rise as a result of the greenhouse effect.

What are greenhouse gases?

The presence of some gases in the atmosphere is responsible for the greenhouse. They are the following:

  • Carbon Dioxide: Carbon-dioxide oxide gas is an important gas in the atmosphere. Its fixed volume controls the temperature in the atmosphere. Fossil fuels are more heavily used mainly by fossil fuels, combustion of thermal power plants, increasing number of automated vehicles and increasing industries. At the same time it is increasing the greenhouse effect.
  • Methane: Methane gas is made of a combination of carbon and hydrogen. According to an estimate, 52 million tonnes of methane gas is being pumped into the air every year, increasing its volume. The reason for the increase in methane gas is both natural and human. Methane gas heats the atmosphere more than carbon dioxide.
  • Nitrous Oxide: Another major gas in greenhouse gases is nitrous oxide, which is growing in the atmosphere at a rate of about 0.25 percent per year. Reasons for its growth include the burning of oceans, hot soils, moist forests, nitrogen fertilizer, changes in land use, deforestation, bio-fraction and industrial sources. It also damages the ozone layer.
  • Chlorofluorocarbons: It is emitted by the use of refrigerators, air conditioning fire fighting equipment, cosmetic plastic foam, etc. It is considered the most dangerous greenhouse gas. They cause the most damage to the ozone layer.

Effect of increasing levels of greenhouse gases

Greenhouse gases have an impact on both the environment and ecology. As their quantity increases, this effect becomes dangerous. The major effects of increasing greenhouse gases are:

  • Climate change especially increases in temperature.
  • Rise in sea level.
  • Damage to ecosystems.
  • Impact on Agriculture.
  • Effect on the ozone layer.

Some measures to prevent the effect of greenhouse gases

Following are some measures to prevent harmful effects of greenhouse gases:

  • Reduction in fossil fuel usage.
  • More use of alternative energy sources in place of fossil fuels.
  • Plantation and classification.
  • Implementing international climate agreements.
  • To introduce the concept of sustainable development in industrial development.
  • To control carbon-dioxide emission industries and other activities.
  • Control of technological development by developed countries.
  • Providing economic and technical assistance by developed countries to control greenhouse gases by developing countries.
  • Ensuring global participation, etc.

The conclusion

To protect the Earth from the threat of global warming, there should be strict rules and laws in which the emission of greenhouse gases is more responsible. The United States ranks highest among the most carbon-dioxide-emitting countries, while the countries of the European Union and China rank second and third, respectively. Ten countries in the world emit more than 70 percent of carbon dioxide, while the rest of the world suffers from the ill effects of the greenhouse effect.
