Global Warming - A threat to mankind

Global warming is the increase in the average temperature of the earth.

As a result glaciers are melting, sea levels are increasing, there is destruction to wildlife.It's clear that humans are responsible for the past century's warming by releasing heat-trapping gases as we power our modern lives. These gases are called the greenhouse gases.

The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse.

First, sunlight shines onto the Earth's surface, where it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.

Carbon dioxide is the most important green house gas. It takes 100 years for CO2 emission to disperse. Driving your vehicle and leaving house lights adds on CO2 quickly.

Regarding my bit to avoid global warming, I ve involved myself in planting lots of saplings over the past 7 years some of them have grown into trees. There are lots of trees in my locality courtesy the Forest Department. There are lots of nurseries close by where in I could get some of the best saplings. Apart from this I do have a solar water heating system and have avoided the use of incandescent lamps where ever possible.
