2. Global warming refers to an unequivocal and continuing rise in the
average temperature of Earth's climate system. Despite the oceans'
dominant role in energy storage, the term "global warming" is also
used to refer to increases in average temperature of the air and sea at
Earth's surface. Since the early 20th century, the global air and sea
surface temperature has increased about 0.8 °C , with about two-thirds
of the increase occurring since 1980. Each of the last three decades has
been successively warmer at the Earth's surface than any preceding
decade since 1850.

3. Environmentalism is a broad philosophy ,
ideology and social movement regarding concerns
for environmental protection and improvement of the health
of the environment, particularly as the measure for this
health seeks to incorporate the concerns of non-human
elements. Environmentalism advocates the preservation,
restoration and/or improvement of the natural environment,
and may be referred to as a movement to control pollution or
protect plant and animal diversity.

5. The effects of global warming are the
ecological and social changes caused (directly
or indirectly) by human emissions
of greenhouse gases. There is a scientific
consensus that climate change is occurring,
and that human activities are the primary
driver.

10. Recycling a ton of “waste” has twice the
economic impact of burying it in the ground.
In addition, recycling one additional ton of
waste will pay $101 more in salaries and
wages, produce $275 more in goods and
services, and generate $135 more in sales than
disposing of it in a landfill.

11. Reducing the amount that we consume, and
shifting our consumption to well-designed
products and services, is the first step. Finding
constructive uses for “waste” materials is next.
And tossing it in the blue bin (garbage bin) is last.
Through a balance of these three principals you
can easily see your landfill-destined waste
dwindle fast.

12. 1. No drips – A dripping faucet can waste
20 gallons of water a day.
2. New fixtures can improve water effectiveness.
3. Cultivate good water habits.
4. Rainwater harvesting – Rainwater can be used like
regular water on your tap!
5. Reuse water, for example greywater can be used for
watering plants.
6.Beaware!– Report broken pipes, open hydrants, and
excessive waste.
7. Take a shower instead of a bath. Bath will cost four times
more energy.

13. 1. Cut down the lost of energy
to minimum.
2. Reduce your use. Replace your light bulbs with
compact fluorescent bulbs (CFLs) or LEDs. Turn off
when they’re not needed.
3. Installing an home alternative energy system. A solar
electric system can provide all the energy.

14. 4. Most energy consumed in home is in heating and
cooling. Keep your house cool with natural ventilation.
Blocking sunlight can help lower your cooling load. Plant
a tree, it will absorb a ton of CO2 over its lifetime. Shade
provided by trees can also reduce your A/C bill by 10 to
15%.
5. plug-in devises are the second biggest users of energy
in your abode. When looking for new appliances, seek
out the most energy-efficient models. Also look for
Energy Star rated products.

15. we realize that our earth is already seriously ill. We can’t
just stand here and do nothing but hurt it more. We must
take immediate, effective action to save our earth. In order
to save our beautiful and peaceful earth, we need to obtain
more knowledge so that we can use it in the effective way.
This world is not ours. This world is owned by the animals
and plant, they came first, after hem only we came . So we
don’t have any right to destroy this planet.
