Is nature in danger?

Nowadays nature is very endangered because of pollution, deforestation, endangered species, global warming... for this reason we have to have information about this.


Pollution: this factor causes instability, disorder, dirt, harm or discomfort to the ecosystem. The pollution happens not only on the land, but also in the oceans because of ships that transport oil and sometimes  have accidents. On the land the main causes of pollution are industry, transport... and also we are a factor of pollution.

Around me there are a lot of cars and for this reason on the 25th of September in my town, Tolosa, they organized an activity called 'Stop Auto'. I was there and in my opinion it was very good, the children of 14  led cars made of cardboard, others went by bike, by scooter and walking.

It's not easy to breathe  clean air and it's recommendable to go to the mountain to breathe  clean air. But nowadays, there is a bigger problem of deforestation and so the forests are disappearing.

Deforestation: it is the overcutting of trees. One of the consequences of this is soil erosion. The result is the damage of the land. For example, when they cut trees to make paper, it causes a lot of effects: for example, the climate change, this is very important and it's happening in a lot of places. Another effect is that there is less biodiversity, so the carbone dioxide is not removed.

Endangered species: there are a lot of animals that are disappearing. The main cause is the habitat destruction, our planet is changing and the animals can't adapt so they die and there are some more causes. So we have to help them by protecting their habitats permanently in national parks or by removing weeds and planting local native species in their place.


Global warming: the temperature of the world is increasing. The icebergs of the Artic are melting and we can't continue like this so we must take measures, otherwise the sea's level is going to go up. The air around the earth is contaminated  and the sun rays don't get out, for this reason occurs the global warming.


As a conclusion, we should recycle more, go by bus instead of  by car, we shouldn't use sprays... in this way we will contribute to save the planet and have a better life for all.
