Each and every one of us is contributing to global warming and we need to do something about it starting right now.
For those of you who are unclear on what is global warming-simply speaking-the global temperature is rising and consequently the earth’s climate is changing. This can have serious consequences world wide. - And we humans are causing it. Can we avoid this disaster by changing the way we live? Frankly we don’t have a choice. Each and every one of us has got to do our bit. It will take a world wide effort. But we need to do it starting now.
How are we making the earth warmer than it is meant to be?
The protective blanket surrounding the earth allows enough of the sun’s energy to warm our planet and retains enough of that heat to make it liveable. Without this protective blanket our earth would be 30C colder than it normally is. This natural heat holding effect of the earths blanket is called the greenhouse effect. But lately we humans have changed the make up of this protective blanket by our activities which emit more carbon dioxide than ever before. Carbon dioxide (greenhouse gas) traps heat (as do other greenhouse gases like methane, nitrous oxide, water vapour). So higher concentrations of greenhouse gases (out of which carbon dioxide has the maximum implications) means a warmer earth. Burning coal creates more carbon dioxide (CO2) than burning any other fossil fuel (oil and natural gas). When we use energy for producing electricity we generate more CO2. Carbon dioxide levels have now reached a peak not seen for the last 900,000 years.
Our world runs on electricity and burning coal provides 40 percent of world’s electrical energy. Coal also emits approximately twice the CO2 as that from natural gas. When we use any form of energy, we produce CO2 emissions.
So how can we help!
Lowering CO2 emissions to help reduce global warming is possible. Walking short distances instead of driving, carpooling, unplugging idle electronics, driving fuel efficient cars, switching off light bulbs when not required, using less hot water, using less electricity, growing more plants in your house, turning primarily vegetarian are some of the steps that may seem very small but when each of us begin to implement them, these small measures will help make a big difference especially if we all choose to do it. It needs a world wide effort.
