Latest Alarm on Plastic Pollution

 In Naturopathic News

Ecologists studying the prevalence of plastic pollution in aquatic ecosystems around the world are concerned after measuring the scale of human response needed to reduce future emissions and manage what’s already floating around out there.

Prevalence of plastic pollution in aquatic ecosystems around the world are concerning

“Unless growth in plastic production and use is halted, a fundamental transformation of the plastic economy to a framework based on recycling is essential, where end-of-life plastic products are valued rather than becoming waste,” says Chelsea Rochman, assistant professor in the Department of Ecology & Evolutionary Biology at the University of Toronto (U of T), and senior author of a study published in Science outlining the accelerating pace with which plastic emissions enter Earth’s waterways annually.

“Even if governments around the world meet their ambitious global commitments, and other countries join those efforts to curb plastic pollution, worldwide annual emissions to rivers, lakes and oceans could be as much as 53 million metric tonnes by the year 2030,” says Stephanie Borrelle, Smith Postdoctoral Fellow at U of T and lead author on the study. “That’s far beyond the 8 million metric tonnes amount that was declared unacceptable in 2015.”

The research by an international group of experts led by Rochman and Borrelle, consisted of an evaluation of the level of effort needed to achieve a global reduction target for plastic pollution of less than 8 million metric tonnes (MT).

Estimated 24-34 million MT of plastic emissions currently enter aquatic ecosystems every year

The group first estimated that 24-34 million MT of plastic emissions currently enter aquatic ecosystems every year. They then modelled future scenarios using existing mitigation strategies: reducing production of plastic waste (which includes bans), improving management of plastic waste that is produced, and continuous recovery (i.e., cleanup) from the environment.

The researchers found that even with parallel efforts in all three solutions, the level of effort required within each is enormous:

(1) a 25 — 40% reduction in the production of plastic across all economies;

(2) increasing the level of waste collection and management to at least 60% across all economies — with a change from 6 — 60% in low-income economies; 

(3) recovery of 40% of annual plastic emissions through cleanup efforts.

“To put that last number into people power, the cleanup alone would require at least 1 billion people participating in Ocean Conservancy’s annual International Coastal Cleanup,” says Borrelle. “This would be a Herculean task given this is 660 times the effort of the 2019 cleanup.”

Even if the prescribed effort is realized, the world remains locked into an unacceptable plastic future

The researchers note, however, that even if the prescribed effort is realized, the world remains locked into an unacceptable plastic future.

“The global community must coordinate a fundamental transformation of the plastics economy, one that reduces the amount of virgin plastic production, and reimagines how we make use and dispose of plastic materials,” says Rochman.

The research was supported by the National Science Foundation through the National Socio-Environmental Synthesis Center (SESYNC).

Node Smith, ND, is a naturopathic physician in Humboldt, Saskatchewan and associate editor and continuing education director for NDNR. His mission is serving relationships that support the process of transformation, and that ultimately lead to healthier people, businesses and communities. His primary therapeutic tools include counselling, homeopathy, diet and the use of cold water combined with exercise. Node considers health to be a reflection of the relationships a person or a business has with themselves, with God and with those around them. In order to cure disease and to heal, these relationships must be specifically considered. Node has worked intimately with many groups and organizations within the naturopathic profession, and helped found the non-profit, Association for Naturopathic Revitalization (ANR), which works to promote and facilitate experiential education in vitalism.
