thuyết trình Global warming

Our Planet is having a serious
problem !


Global warming has become perhaps the
most complicated issue facing world
nowaday


What will be
covered
1. What is global warming.
2. Cause of global warming
3.Effect of global warming
4.Solution


1. What is “Global Warming”?

Global warming is the rise in
the average temperature of
the earth due to the increase
of greenhouse gases like
carbon dioxide, carbon
monoxide, methane and
others in the atmosphere.



2. What causes Global Warming?

DEFORESTATION FOR
FARMLAND, WOOD,
PAPER

INCREASE IN USAGE OF
CHEMICAL FERTILIZERS
ON CROP LANDS


3. Effect of global warming
More extreme heat
waves during the
summer; Less
extreme cold spells
during the winter

Many country like India or parts of Africa are
very hot because of the heat from
Greenhouse effect



*Ice Melting

A huge iceberg breaks off the Antarctic peninsula.
The Antarctic ice sheet holds 70 per cent of the
world's fresh water

1 - 2 mm/year over the

past 100 years


Many Species Die due to the
changing of sea level…


*Extreme weather



4. SOLUTIONS

• Government


• Citizens
* Reduce the use of plastic bags → as burning
plastic emit CH4
* Reduce the use of use of air-conditioner,
which will emit CFCs
  
* Use public transportation instead of private
cars → reduce the pollutants emitted by cars


Our thoughts
Global Warming is a serious problem facing us; we need to help, decrease the
pollution and improve the environment after all. We do it not only to save
ourselves, but also to save the Earth, the humanity…
