          A report from the United Nations given at the conference unveils how worrying the pollution caused by plastic utensils, especially plastic bags, is becoming. In a single minute, the world consumes one million plastic bottles; in a year, the world consumes five billion single-use plastic bags, according to Vietnamplus. The scary fact is that such plastic bottles and bags are not properly treated, as each year, the world discharges 300 million tons of plastic waste, accounting for some 10% of all solid waste, putting the environment and human health under tenterhooks, according to the news site.

The conference also drew attention to another fact: “For a plastic bag that can be used for five minutes, it takes five seconds to produce, one second to discard, but 500 to 1,000 years to become totally decomposed,” says Vietnamplus.

In another message given by the UN General Secretary and delivered at the conference, it is reported that since more than eight million tons of plastic bags end up in the oceans each year, “microplastics in the seas now outnumber stars in our galaxy.” “If present trends continue, by 2050 our oceans will have more plastic than fish,” Dan Tri reports, quoting Caitlin Wiesen, country director of the UN Development Programme in Vietnam.

These above-mentioned fearful facts, however, are not merely global issues, but domestic problems as well, according to local media. Many local news outlets, when relating data from the conference, point out that white pollution – a term used to indicate the overwhelming discharge of plastic bags into the environment – is even getting worse in Vietnam than elsewhere.
