TEMA AMBIENTE E INQUINAMENTO

Tema sull'ambiente e l'inquinamento.

The environment and the pollution. In the world there are a lot of serious problems: one of these is the pollution.
When we destroy or contaminate the environment with various waste, we pollute.
There are 4 kind of pollution:
- Air pollution: air transportation, factory fumes, road traffic, cfcs;
- Water pollution: oil spills, industrial waste, shipping (oil tankers and cruise ship), fertilizers carried by rain;
- Land pollution: pesticides, industrial waste, rubbish and fertilizers;
- Noise pollution: air and rail transportation, road traffic, lawn movers, car alarms and lawn mowers.
We must remember that: glass never decomposes, plastic decomposes in 1000 yrs, while aluminum decomposes in 500 yrs.

There is a little solution for this: the 3 Rs: reduce, reuse and recycle. If all the people do this, we can save the Earth.

Recycling is the reprocessing of old materials into new products, with the aims of preventing the waste of potentially useful materials.

- unleaded petrol;
- an endangered species;
- the deforestation, with someone who cutting down a tree in a rainforests;
- the factories pulling the air;
- pollution river.
The Earth is in danger!!! We must save it.
One of the main risks for our planet are the acid rain: they form when the gases from cars and factories mix with atmospheric water. These rain destroy forests, many animals and plants don’t survive. In the next 30 years one quarter of animals bird and fish will die for the disappearance of natural habitats, pollution and hunting.

A solution is the alternative energy. These are subdivide in 2 team: renewable and not renewable energies.
The renewable energies are the wind, the solar, the geothermal and the ocean; the not renewable energies are the oil, the natural gas and the coal.
