Global warming is caused by both natural and man-made factors. Natural causes include the release of methane from arctic areas, while man-made causes are pollution from burning fossil fuels, increased CO2 emissions from population growth, and transportation and deforestation. The effects of global warming include rising global temperatures and sea levels as well as decreasing snow cover. Some solutions proposed are improving fuel efficiency when buying cars, using more efficient light bulbs, planting trees, taking showers instead of baths, and reusing shopping bags.

1. GLOBAL WARMING

2. CAUSES
I. Natural Causes
- release of methane gas from arctic tundra
and wetlands (mlaştini).
Methane is a greenhouse gas.
A greenhouse gas is a gas that
traps heat in the earth's atmosphere.

3. CAUSES
II. Man-made Causes
3. Pollution
-Burning fossil fuels (coal, oil) => CO2

4. 2. Population
Since CO2 contributes to
global warming, the increase
in population makes the
problem worse because we
breathe out CO2.
3. Transportation

5. 4.Deforestation
the trees that convert our CO2 to oxygen are being
demolished because we're using the land that we cut the
trees down from as property for our homes and buildings.

6. EFFECTS
• rise in global temperatures
• rise of sea levels
• Decrease of the snow cover

7. SOLUTIONS
1. When you buy your car, look for the one
with the best fuel economy in its class.
• replace your incandescent bulbs with
more efficient compact fluorescents

8. SOLUTIONS
3. Plant a tree.
4. Take a shower instead of a bath
5. Reuse your shopping bag

9. DAVID TODD
- WHERE WE GOING TO GO -
They came in the night and they came in
the day
They came until they took it all away
And all they left was a barren ground
Where no life can be found
They didn't give a reason and they didn't
say why
Millions of trees had to die
In the name of progress was all they'd
say
Step aside and get out of our way

10. • What I want to know is where we gonna go
When the rain don't make our garden grow
And the soil's too dry for the seeds to sow
How long till we learn
You play with fire and be sure to burn
A one way ticket with no return
Cause where we gonna go
Well I don't know

11. • They tell us technology is a wonderful thing
• Not to mention the destruction it brings
• One step forward and two steps back
• Go from the light and into the black
• They feed us with lies and treat us like fools
• But don't stop to realise its a game we all lose
• On a road to self destruction with every step we take
• Like a ship sinking fast and
• no escape

12. • What I want to know is where we going to go
When the sun’s threat to all below
And our pollution stops our rivers flow
It’s time you and me take responsibility
It’s a fragile world in dire need
Cause where we gonna go
Well I don't know
Spending money to find life on Mars
It doesn't make any sense to me
Like trying to live at the bottom of the ocean
Some things are not meant to be.

13. • What I want to know
Is where we going to go
When the ocean rise and the
strong winds blow
And the temperature melts the
ice and snow
Not time to wait
It won’t be long and it will be too
late
In this together and we are all at
stake
Cause where we gonna go
Well I don't know
