Is for everybody well known that pollution is a big deal that we are trying to treat.
The first document shows how the United States evolved creating more P.V. Installations (Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials). There will be 8.000 pv installations in 2016, and the sales, as the document shows will be of 14%.
Despite of these numbers is this enough progress?
One type of pollution that is not very well known is LIGHT POLLUTION and it is also not taking always considered because there's almost no social conscience about it. Despite generating large and damaging consequences such as wasted energy, the greenhouse gases resulting from their production. It makes also harmful effects on humans and animal's health, difficulties in the air and maritime traffic, difficulties in the study of stars and in general a loss of perception of the universe. It's likely that many of the negative effects of light pollution are not known yet. If we compare the two documents is obviously that the measures took by the United States are not enough, they are insufficients. The solutions will have to take a larger scale because as the document 2 shows, the majority of the United States of America will surpass between 100% above the natural brightness level and 9 to 27 times the natural brightness level.
Every country in the world must take care of all kind of pollution and they can't forget light pollution. Even if the governments and the associations are trying to reduce the pollution and the greenhouse effect, the solutions still not deep enough to stop somehow the danger we face.
