The planet is literally drowning in garbage, and it is high time to clean up, UN Secretary-General António Guterres said on Thursday, at an event in the General Assembly Hall marking the first-ever International Day of Zero Waste.

The high-level meeting was held to raise awareness of the urgent need to transition to a “green” and circular economy that promotes sustainable production and consumption patterns. The move could save governments billions and create hundreds of thousands of jobs.

Humanity currently generates more than two billion tonnes of municipal solid waste annually, which includes plastics, textiles, rotting food, discarded electronics, and debris from mining and construction sites.

As the Secretary-General bluntly put it, we are basically “treating our planet like a garbage dump”, warning that the messy mountain will reach four billion tonnes by 2050.

“We are trashing our only home,” he said.  “We’re spewing a torrent of waste and pollution that is affecting our environment, our economies, and our health.”

Mr. Guterres said it was time for “a war on waste” on three fronts, calling on polluters themselves to take the lead.
