GLOBAL WARMING

SOFIA VEGAS

WHAT IS IT?The GLOBAL WARMING is the increase of temperature because of the ARTIFICIAL GREENHOUSE EFFECT

GREENHOUSE EFFECT

GREENHOUSE EFFECT

The GREENHOUSE EFFECT occurs because of a type of pollution of the air that slowly raises the temperature of the earth

GREENHOUSE EFFECT

The sun heats the earth and its polluted atmosphere doesn’t let the gases go back into the space

THE GASES OF THE GREENHOUSE EFFECT

H2OThey are from WATER STEAM

CO2They are from CARBON DIOXIDE

N2OThey are from NITROXIDE

CH4They are from METHANE

O3They are from OZONE

GREENHOUSE EFFECT

If all of these gases get together, they create a layer in the atmosphere that keep the heat of the sun on the earth

GREENHOUSE EFFECTThe greenhouse effect is a natural effect that prevents us from freezing

GREENHOUSE EFFECT

But if we abuse too much and we produce a lot of gases, it could have consequences

SUCH US….

The temperature of the earth is increasing every

year 0,2 degrees

It melts the surface of the glaciares, therefore, the

level of the sea has increased 2,6mm every year

since 1993

There could be many flooded zones near the sea,

and if the level of the sea continues increasing, in

some years many islands could be under the sea

It affects the ecosystems of many plants and animals, and they have to adapt to the new weather also affecting humans

We could have less fresh food for lack of water

Types of pollution

Pollution of the water

This type of pollution happens when the humans throw garbage into the sea

The consequences of these acts are that many sea

animals drown or get caught in the plastic bags

Air pollution

It is caused by cars and factories

This type of pollution affects the weather and increases the temperature, it is also the one that causes the

GREENHOUSE EFFECT

Phonic pollution

It is caused by cars, machines and construction

machines

As a consequence the animals can´t hunt because their preys are scared

It also causes many animals to leave their ecosystems and move to other places and if they do not find a place they can adapt to they could die

Light pollution

These happens, for example, when we build

roads near ecosystems and we put too many streetlights

that give a lot of light and the cars that cross the roads

at night have bright lights too.

This means that many animals cannot sleep well

and they have to go to another place to live

But the animals do not know if the place they are going to

have food or a climate adapted to them, therefore,

they could die

Floor pollution

This happens when we throw garbage to the ground

or when we use the inappropriate pesticides with

the plants

This makes that after a few years, when the garbage

and the earth get together, the plants grow bad and

contaminated

What could we do to avoid Global Warming?

It is very important to know how to avoid Global

Warming and there are so many things that we could

do to help the planet

FOR EXAMPLE...

CHANGE THE LIGHT BULBS

Changing the normal bulb for a low-energy one saves 45 kilograms of dioxide per year.

TURN OFF ELECTRONIC DEVICES

Turning off the TV, the computer and the lights when you are not using them and unplugging the phone when it is charged helps to reduce pollution a 30%

DRIVE LESS

If you take the bus or public transport we reduce the pollution and for every 4.5 kilometers that you do not drive you will reduce 30 grams of carbon dioxide

CHECK THE TIRES

If you do not check the tires they could break and you would have to buy new ones, and apart from spending a lot of money, it contaminates a lot

USE CLOTH BAGS

If you use cloth bags instead of the plastic bags you could reuse them and it is more difficult for the sea animals to eat them
