Téma: The Environment
An ecosystem is a group of living things and the whole place where they live. One kind of ecosystem is a desert. It has special plant that live only there, lizards, snakes, vultures.
The earth has a thin atmosphere that is like a transparent blanket that keeps us warm. Temperatures of air and water increase. This could cause rising sea levels, unpredictable weather in the form of flooding or drought, hurricanes and large loss of life.
The Greenhouse Effect
It is when the air or atmosphere gets too hor. Air warmed by the sun gets trapped clo to the ground and can´t escape. It is caused by too much carbon in the air, from factories, cars.
The ozone layer
It protects us from the harmful rays of the sun. It is in the atmosphere and surrounds the Earth. There is a hole in the ozone layer over the Antarctic. In Australia it is very thin. It absorbs dangerous ultra violet radiation. The UV causes damage to the DNA. This can cause cancer in humans.
Deforestation is very dangerous for many reasons. Because we need oxygen which comes from rainforests and forests. The deforestation can cause extinct of many plant and animal species. Rainforests catch the water and give it back to the Earth in the form of clouds, which bring us water. People burn and cut down rainforests for agriculture. This is happening in the Amazon basin in Brazil.
There are a lot of extreme weather…..tornados, hurricanes, earthquakes, gale-force wind. Extreme weather is a part of nature.
People use some products for cleaning, which contain strong chemicals. For example there are batteries, which are dangerous waste, so we must put them into the special boxes.
There are also environmentally friendly products. On the package we can see some symbols, ecofriendly, BIO, natural product.
Paper and cardboard can be recycled by mixing it with water and creating new paper or cardboard products. Glass bottles can be cleaned and used again or melted down and used for different product. Plastic bottles can be melted down and made into plastic pipes and toys.
In my region is a big air pollution. Because there are a lot of factories, especially DEZA, which processes coal tar. Also a lot of traffic. People could try to more recycle. They don´t do it, because they are lazy.
