Question

prepare an article on the hazardous impact of plastic on nature​

Answer 1

Answer:

Policies for managing plastic debris are outdated and threaten the health of people and wildlife, say Chelsea M. Rochman, Mark Anthony Browne and colleagues.

Last year, 280 million tonnes of plastic was produced globally. Less than half of it was consigned to landfill or recycled. Of the remaining 150 million tonnes, some may still be in use; the rest litters continents and oceans (see 'Plastic world').Plastic debris can physically harm wildlife1,2. Moreover, many plastics may be chemically harmful in some contexts — either because they are themselves potentially toxic3 or because they absorb other pollutants4,5. Yet in the United States, Europe, Australia and Japan, plastics are classified as solid waste — so are treated in the same way as food scraps or grass clippings.

We believe that if countries classified the most harmful plastics as hazardous, their environmental agencies would have the power to restore affected habitats and prevent more dangerous debris from accumulating. Ultimately, such a move could boost research on new polymers and replace the most problematic materials with safer ones.

It is now almost impossible to walk in the countryside or on a beach without encountering bits of plastic. Larger pieces, from bottles and bags to floating pontoons, can transport species to new habitats where they might do damage. Such debris can kill or injure ecologically and commercially important species, including mussels, salt-marsh grasses and corals1,2. Mammals, reptiles and birds can also be harmed through eating plastic or becoming entangled in it. Last year, the secretariat of the Convention on Biological Diversity in Montreal, Canada, reported that all sea turtle species, 45% of marine mammal species and 21% of seabird species can be harmed in this way.
