“The Earth is a generous mother, she will provide in plentiful abundance food for all her children if they will but cultivate her soil in justice and in peace.”
Global warming refers to the sustained increase in the average temperature of the earth’s atmosphere. In simple words, the phenomenon of warming of the planet Earth is known as global warming.
The chief indicators of the global warming are as under:
• Ozone Depletion
• Greenhouse effect
• Burning of Fossil fuels like coal, oil and natural gas which release greenhouse gases in the atmosphere.
• Rapid industrialisation
• Motor vehicle exhaust

40% of US CO2 emissions come from electricity production. Burning of coal accounts for 93% of emissions from the electric utility industry. Every day, more electric gadgets flood the markets. Without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.
Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions. With our population growing at an alarming rate, the demand for more cars and consumer goods is increasing. It means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects. There is no end in sight to our massive consumer culture.
Methane is another extremely potent greenhouse gas. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestine of herbivorous animals. With the increase in the amount of concentrated livestock production, the level of methane released into the atmosphere is increasing.
The use of forests for fuel, both wood and for charcoal is another major cause of global warming. Our appetite for wood and paper products contributes to the mass deforestation. Forests remove CO2 from the atmosphere and store it. But this deforestation is causing the release of large amounts of carbon dioxide in the atmosphere and the warming of the Earth.
In the last half of the 20th century, the use of chemical fertilizers has risen dramatically. The high rate of application of nitrogen-rich fertilizers has effects on the heat storage of cropland. Nitrogen oxides have 300 times more heat-trapping capacity per unit of volume than CO2. In addition to this, high nitrate levels in groundwater due to over-fertilization are the cause for concern for human health.
The effects of global warming are:
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctic and Greenland, especially on the East Coast of the US. However, many nations around the world will experience the effects of rising sea-levels, which could displace millions.
The security of storms such as hurricanes and cyclones is increasing. Scientists have come up with the foremost evidence so far that global warming will significantly increase in the intensity of the most extreme storms worldwide.
According to recent research, there is a 90% chance that 3 billion people worldwide will have to choose between moving their families to milder climates and going hungry due to climate change within 100 years. Climate change is expected to have the most severe impact on water supplies. Shortage in future is likely to threaten food production, reduce sanitation, and hinder economic development and damage ecosystems.
Rising temperatures could lead to the extinction of...
