However, plastic, except for all its remarkable properties, has two important drawbacks. Firstly, it is produced from non-renewable natural resources - oil, coal and gas. Secondly, its main advantage - longevity - which the inventors of plastic so chased at the beginning of the last century, turned into a disadvantage today. The more plastics we use, the faster the mountains of waste grow, which do not decompose in the medium under any conditions. Millions of tons of plastic accumulate in nature, polluting the environment.
