we all know, global warming is more evident now than ever before.
Environmentalists and world leaders are taking active steps to promote
and practice sustainable living and educate the people all over the
globe about the imminent threat to our environment which has reached the
Sustainable living is choosing to live in a way that will preserve our
natural environment or at least minimize the demand or use of resources
that are not renewable such as oil. Saving our planet from man made
destruction is not just the responsibility of the environmentalists and
political leaders. Everybody has contributed to the pollution one way or
the other so everybody has to practice sustainability.
How do you practice sustainable living and help the environment?
— Turn off and unplug appliances when you are not using it.
Televisions, DVD players, game consoles and other appliances are not
totally turned off even if you turn it off. As long as they are plugged
to the outlet, they still consume about 10% of the amount of electricity
of the electricity they consume when they are turned on.
— Use light bulbs that do not waste electricity. LED lights and Compact
fluorescent light bulbs (CFLs) consume less electricity compared to
incandescent light bulbs. In an incandescent bulb, electricity runs
through the thin filament of the light bulb and the filament produces
resistant to the electricity. This resistance then turns electricity
into heat. The heat generated causes the filament to become white hot
and the “white” part is what we see as light. The problem with
incandescent lights is that the heat wastes a lot of electricity and it
only produces about 15 lumens per watt.
The fluorescent bulb however works this way: there is a stream of
electrons flowing between the electrodes at both ends of the fluorescent
bulb. The electrons interact with mercury vapor atoms floating inside
the bulb and that excites the mercury atoms. After that, they return to
an unexcited state and they release photons of light in the ultraviolet
region of the spectrum. These ultraviolet photons collide with the
phosphor coating the inside of the bulb so the phosphor creates visible
Unfortunately for human health and the environment, CFLs outgas toxic
mercury vapors. The best option for lighting is the ultra efficient LED
lights which consume a fraction of the electricity of CFL bulbs.
— Reduce tap water usage at home. Fix or replace faucets dripping
water. Do not water gardens at noon when the sun’s at it’s highest point
and evaporation rate is greatest.
