It's predicted that by 2050 there will be more plastic than fish in the oceans of our planet. One of the biggest and least studied problems is microplastic. Microplastic is not a particular type of plastic, but any plastic particle less than 5 mm long. It comes into [debris| pollution| spoil| degradation| threat| environment| fumes] through numerous sources like clothing microfibres, fishing nets, plastic water bottles and packages. Although plastic  [debris| pollution| spoil| degradation| threat| environment| fumes] takes dozens of years, it takes only several months for this material to start breaking down. Washed away into the oceans, the plastic [debris| pollution| spoil| degradation| threat| environment| fumes] is often mistaken for food and swallowed by marine animals. It is accumulated in their tissues and can further be found in humans' food. The scale of microplastic [debris| pollution| spoil| degradation| threat| environment| fumes] is unbelievable. The tiny particles have been found in rain, rivers, oceans, drinking water and even bottled water. Nevertheless, the health organisations claim that microplastic doesn't pose a [debris| pollution| spoil| degradation| threat| environment| fumes] for human health. But it is also stated that this problem needs more research.
