Science and new technologies made our lifestyles much easier and more comfortable. However we aren’t alone on the planet and we usually underestimate the damage which science development gives to the environment.

Firstly, one of man’s worst inventions is a plastic bag. Although we use them every day and it’s a multifunction thing, plastic bags end up lieing in the streets. If too much plastic ends up in water, it creates a layer that denies oxygen and no plant or animal can survive in it. If animals eat plastic bags found in their habitats, they die painful deaths. Plastic is not ecological, because it needs hundreds of years to decompose and it can not be turned into any other substance that is eco friendly. Today plastic bags are widely used and it causes serious environment pollution.
