Global Warming has been one of the greatest concerns for mankind in recent times. Here's a simple definition of global warming. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. Never before has the earth become so warm as it has been of late. And the experts see the trend is accelerating. There are clear indications that our planet is getting warmer day by day. Global warming occurs when carbon dioxide and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface. Normally, this radiation would escape into space-but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the Greenhouse effect. The huge mass of ice gathering in the North Pole and South Pole has started melting. There have been cases where damage and destroying of marine life has been confirmed due to the rising of temperature of sea waters. The Gangotri Glacier which is the main source of water for the Ganges is reported to have been fast diminishing over the last few years. Rainfall recorded in different parts of the globe has been quite erratic and irregular. These are some of the signs and symptoms confirming the earth's growing temperature. The reasons for the planet getting warmer are many. The major reasons for this Global Warming are the large scale of deforestation, use or consumption of fossil fuel for transport and cooking purpose, excessive and indiscriminate use of chemical fertilizers, pesticides and insecticides in cultivation.
To combat the challenge of global warming, the above contributing factors have to be checked and eradicated at all costs. Afforestation has to be encouraged and alternative energy resources invented and use of biological and natural fertilizers, insect and pest killers has to be ensured. The Menace of global warming must be fought with a global planning.
