Global Warming.

The Earth's climate is going towards its destruction very fastly and there include many factors in its destruction one of those is Global Warming. Global Warming is a natural process by which the atmosphere retains some of the sun's heat, allowing the earth to maintain necessary conditions to host life. Without the greenhouse effect, the average temperature of Earth would be -18 degrees Celsius. So there arises a question that if global warming is necessary to maintain the Earth's temperature to host life then why it is damaging our environment? The simple answer could be "EXCESS OF EVERYTHING IS BAD", but it isn't the same. The main fact is that daily human activities have maximizes the greenhouse effect that results in an unexpected rise in temperature(Discussed later in Blog) which is quite alarming. Warming greater than global has already been experienced in many regions of the world with higher warming averaging over the land than over the oceans. Talking about the reasons behind Global Warming includes an increase in the Green House effect, Deforestation, and UN-controlled Population Increase.

• Green House Effect: The greenhouse effect is simply described as the process that occurs when the gasses in the earth's atmosphere traps the sun's heat. This makes the earth much warmer than it would be without an atmosphere. A typical greenhouse is building with glass walls and glass roofs to grow plants and vegetables which are offseason. During the day when the sun shines the greenhouse glass trap its heat which helps him stay warm even in winters at night.

  Gasses in the atmosphere traps heat just like the glass roof of the greenhouse. These trapping gasses are called Green House Gasses. Scientists have shortlisted some gasses that are called greenhouse gasses Carbon Dioxide, Methane, Nitrogen Dioxide and Chlorofluorocarbons (CF Cs) these gasses are heating our atmosphere by trapping Infrared rays coming from the sun. Human activities are increasing the emission rate of CO2 by burning of excessive fossil fuels. Also, the emission of CF Cs mainly by refrigerators and air conditioners is damaging our environment. Also the smoke coming from the chimneys of Industries also the main factor behind the rise of temperature in the lower atmosphere.
  

The volcanic eruptions are considered to be large enough to effects the earth's climate. On a scale of 1 year, the volcanoes inject 100,000 tons of SO2 in the stratosphere

• Deforestation: Deforestation, clearance, clear-cutting is the removal of a forest or more precisely trees from a piece of land to convert them to farms or urban use. Deforestation is a contributor to global warming and is often cited as one of the major causes behind global warming or enhancing the greenhouse effect. Tropical Deforestation is responsible for 20% of world greenhouse gas emissions and it also causes CO2 to linger in the atmosphere. A forestry expert quoted by Natural Resources Defence Council Described clear-cutting as "An ecological trauma that has no precedent in nature except for a major volcanic eruption". Deforestation is also responsible for Air Pollution cutting down of trees mean less oxygen is being provided to the atmosphere in this scenario the toxic gasses being emitted by Industries stays in the atmosphere and starts polluting it. This also results in all of us breathing toxic gasses that are not good for our health.

• Increase In Population: The rapid increase in Population has also demanded a rise in resources such as energy, food, water and many more which speed up greenhouse gas emission from all production processes. Didn't get it not a problem..have a look. Earth's current population is about 7.3 to 7.5 Billion which means there are more than 7 billion bodies to be fed, clothed, kept warm at the same time this needs a bulk amount of resources which eventually results in huge amounts of waste. According to the United Nations report, the world population will b 9.0 Billion by the end of the year 2050 and these numbers will continue to grow. The impact of humans growth on the environment takes two major forms: 

1. consumption of resources such as food, land, water, air, fossil fuels and minerals.
2. waste products as a result of consumption such as air and water, pollutant, toxic materials and green house gasses.

We as human beings have gone too far but if we didn't think at this moment we will be in trouble in future.
