Is global warming entreating man to return to basics in living?
Today, a child grows up with computers and all the technological advances there are. These consume energy. Can one live without these appliances, gadgets and advancements?
I do not understand much about global warming.
It appears before the Industrial Revolution, the amount of carbon dioxide and other greenhouse gases released into the atmosphere equals that stored in mother earth. For example, plants take in carbon dioxide when they grow in spring and summer and released that back to the atmosphere when they decay and die in fall and winter.
Since then (mid-1700s), fossil fuels were burned to run cars, trucks, aeroplanes, factories and power plants – these add to the natural supply of greenhouse gases.
According to sources, the atmospheric levels of carbon dioxide are determined by the amount of coal, natural gas and oil were burnt and number of trees cut down, as well as the natural processes like plant growth.
Apparently the warmer the atmosphere, the more water vapour it can hold. As a result water vapour is part of the amplifying effect which is beyond man’s control. So the best way to lower temperature and thus reducing water vapour levels is to reduce carbon dioxide emissions.
The high levels of carbon dioxide emitted have caused ocean acidification which is potentially devastating on marine life and fisheries. (And we are encouraged to take seafood sensibly.)
If ozone hole is a thinning of the stratosphere’s ozone layer due to man-made chemicals which lets in more harmful ultraviolet (UV) radiation while global warming is the increase of earth’s average temperature due to the build-up of carbon dioxide and other greenhouse gases in the atmosphere from human activities, then I’m a little confused about saving the earth.
Appliances and gadgets (e.g. air-conditioners and heaters) that were luxuries in the past generations have become necessity today.
Developing countries like China where the population had been accustomed to the basics are now looking to that enjoyed by the developed nations like owning a car which is a status symbol to cycling a bike.
Personally I’ve come to a full cycle – less of those strapping of modern gadgets, appliances and amenities. I want to lead a simple life and live in simplicity. Living with one item of that I need rather than going for the latest! Be contented with that I have: recycle, reuse and reduce! Pedantic?!
