By chance, dropping a bottle with water to your feet, you will relieve a breathtaking, thinking "How is good that scientists invented such practical material as plastic". After all, if it were not for him, the floor would be flooded with liquid, and you risked to step on sharp fragments.
Imagine that you went hiking and, of course, took with me mineral water in a plastic bottle. After a few hours, all the water is spent and unnecessary plastic can be thrown away. But here's the problem - there is not a single urn around, and the idea is creep: "And not to throw this bottle somewhere here - sooner or later plastic will decompose." But the responsible and sensible person will never do that. Organic materials, such as, for example, wood, being buried to the soil, quickly decompose and turn into compost bacteria. But when it comes to plastic, the bacteria will not help with its decomposition.
It may seem that the thrown plastic bottle will decompose forever, but, of course, it is not. Where bacteria will not help, the sunlight will help. Ultraviolet rays destroy the molecular structure of plastic, gradually turning the plastic bottle into the pile of small plastic fragments. Especially strongly this process is noticeable in those parts of the ocean, where plastic garbage flows are going to the huge islands from plastic bottles and cellophane packages. Environmentalists noticed that if the new garbage is not joined to the "island", with time it begins to decrease. It has been established that under the influence of direct sunlight, an ordinary plastic bottle is destroyed for about a year.
Can I breathe with relief - the problem of plastic decomposition solved? By no means. Harmful substances contained in plastic do not go anywhere. Plastic packaging launched on the surface of the ocean (for example, bisphenol A, causing oncological diseases), which, dropping to the bottom, poison marine inhabitants, settled in their gills.
Without plastic bottles and packages, modern civilization can no longer present their lives, but the problem with the pollution of the environment by plastic needs to be solved as soon as possible. The most promising idea is to use natural products for the production of plastic containers. The advantages of this method are obvious: a plastic bag, made, for example, from corn starch, will decompose in just a half months.
In the meantime, new technologies on the approach, each of us can contribute to the preservation of the surrounding nature. To do this, it is enough just to throw a plastic bottle or package to the place intended for this, and not throw away where it fell.
