All over the world , pollution has become the biggest threat for our planet . Every year , the most influencing leaders meet to discuss about possibile solutions , but nothing seems to change : as soon as you watch the TV or listen to the radio , you woould probably thing that our world is going to end because of this irresponsible behaviour: will things change? I can’t be sure . It’s easy to see what kind of black cloud is left behind public transports: imagine this phenomenon spread everywhere ( of course, except for destitute countries ) to have an idea of the human pollution impact on the nature , as well as the incredible plenty of plastic over the rivers and seas. Our children are likely to eat plastic rather than fishes in the next future! The biggest problem is that only a few people are really engaged on changing their habits , on being aware that we , as humans , have the responsability for the life of the earth. However, we are still on time to change ourselves: by the 2030 cars run by diesel will be deleted from the circulation, and we’ll see a great demand of electric ones ( even these days they are being increasily built ). Will this be enought? No, of course, but it could be an optimistic beginning!
