Humanity has already exceeded the planetary limit of pollutants

The global threat of plastic pollution and other polluting substances is a ‘planetary emergency’ equivalent to climate change.

 

We have crossed the limit

The study, published in the journal Environmental Science and Technology , argues that human activity has exceeded the planetary limit for plastics and other pollutants, defined as “new entities” that have the potential to disrupt Earth systems. There are about 350,000 of these “new entities” in the global market, according to the researchers, including plastics, pesticides, industrial chemicals, chemicals in consumer products, pharmaceuticals and antibiotics. And many of them reach the environment.

There has been a 50-fold increase in chemical production since 1950 . This is projected to triple again by 2050,” Patricia Villarubia-Gómez, co-author of the study from the Stockholm Resilience Center (SRC) at Stockholm University, said in a press release. “The rate at which societies are producing and releasing new chemicals and other novel entities into the environment is not consistent with staying within a safe operating space for humanity.”

To reach this conclusion, the researchers compiled data on the rate of chemical production, along with the rate at which fossil fuels , which are used to create chemicals in addition to being used as fuel, are being extracted.

 

To do?

Experts do not doubt that strict regulations must be implemented that represent real barriers around the production of plastic and chemical products, similar to those that already exist for carbon emissions.

“We need to work to implement a fixed limit on the production and release of chemical substances,” they conclude.

PASA, a company that transcends its environmental commitment

Through efficient waste collection and sustainable solutions, the company responds to the needs of society and the planet.

The oldest living fossil is Triops cancriformis.

Living fossils are living things with an ancient lineage and have changed little or nothing in tens or hundreds of millions of years, and among them, triops are the oldest species.

This spider can stay underwater for more than 30 minutes.

Underwater hideout? A team of scientists has observed that some tropical spiders can dive in the face of a potential predator threat.

The theory of strategies r and K, a simplification of reality

Wilson and MacArthur's theory of 1967 was revolutionary in the field of evolutionary ecology, but today we know much more and it has become obsolete, except as a teaching tool

What is the memory of the oceans and why are they losing it?

As our climate changes, the world's waters do too, with anomalies evident in their temperature, structure, currents, and even their color.
