Transcript of Pollution Project
By Carmen Arranz and Carlota Moya.
What is pollution?
What are the different types of Pollution?
Effects of pollution
What does Science do to improve the situation?
Pollution is the action of man made contamination of the environment, but it can be also polluted by natural disasters.
Water pollution is the contamination of the water.
Water pollution has severe human consequences, because less than 3% of the Earth contains potable water and we cannot live without it. If you drink contaminated water you could get ill.
Climate Change is the most serious problem we face in the 21st century. So we have some solutions for it:
Oxford Science 6
Land pollution is the action of environmental contamination with man-made waste on land.Most landfills pollute a lot.
Air pollution is the action of human contamination in the air.
The air we breathe is composed of a mixture of gases:nitrogen, oxygen, and of other different gases But it also contains harmful subtances that you may also breath so it is bad for our health.
*Greenhouse gases contribute to the greenhouse effect
(global warming). These gases retain heat within the
atmosphere, raising the tempertures of the Earth and
also it can produce climate change.
The "Big Six" air pollutants are:
Other types of pollution are:
In the climate
In our health
Lungs and skin cancer
The Poles melt
Sea level rise
Loss of biodiversity
Scientists are also trying to help to
stop pollution. These are some things
they have think:
You also can
* Don't throw
chemical or toxic
substances to water
* Reduce, Reuse and
*Turn off electrical devices
*Use whenever you can public transports
*Created artificial trees
and algae to absorb the CO2.
*Use alternative energies,
*Created bioclimatic houses and ecologic cars.
Trees that absorb CO2. Now they are testing
artificial trees that capture co2 and bury it
underground . A single artificial tree absorbs 10
tons a day of this gas, but it is very expensive, each
tree costs about 13.900 euros.
They have designed a project to place on the houses panels of algae that absorb CO2 through
but they are very expensive
There are bioclimatic houses that reduce the
energy used when you put on the air conditioning
or the heater. These houses need some important characteristics that you have to know before you start constructing. There are also other ecologic houses and buildings.
Cars are also developing. Now there are cars that pollute
less. Some examples are: air cars, hybrid cars,electric
But... it is better if you use your
