Piero Angela in his well-known TV show Superquark says: "In reality it is not plastic that pollutes but the rudeness of those who throw it on the street after using it or even worse in the sea".
A clear and flawless sentence. The pollution of the soil and terrestrial waters are mainly due to the misuse of a material that has positively changed many aspects of our life, in particular that of medicine where plastic sees a massive use both in technology and in sterile tools.
The materials that are usually indicated as possible substitutes they have polluting aspects to take into account: «Glass and aluminum, for example, require much more energy for production and are heavier to transport. Trains, cars and planes are also lighter thanks to plastic. Result, if we suddenly remove all the plastic? More energy burned, more greenhouse gases and more pollution ».
The TV show Superquark with the simplicity that distinguishes it clarifies these aspects by reporting some Italian examples of virtuous recycling.
In recent years, things are slowly changing, but there is still a lot to do, and it is essential to make man more responsible on the culture of recycling.
