As the world celebrates World Clean Air Day, it has become increasingly apparent that plastic is one of the most significant contributors to global contamination. Plastic pollution severely impacts ecosystems, biodiversity, and soil—the very foundations essential for the survival of both humans and wildlife. Tackling the root causes of plastic pollution throughout its entire lifecycle requires collective action.
An ambitious Global Plastics Treaty has been proposed as a crucial step to unify global efforts toward achieving a pollution-free environment. This treaty is seen as instrumental in transforming the way plastics are produced, consumed, and disposed of.
The unique potential of a global, United Nations-led treaty lies in its ability to hold all countries to a high common standard on plastic consumption, creating a clear path toward a future free from plastic pollution. Such a treaty would establish a level playing field, incentivizing and supporting national actions.
According to the United Nations Development Programme (UNDP), it is more important now than ever for member states to unite to create a more sustainable future. Protecting biodiversity is crucial, as all life depends on its continued thriving.
Plastic pollution poses a significant threat to the planet’s biodiversity. Earth is home to millions of species of plants and animals, and the harm inflicted on vital ecosystems by plastics limits their ability to thrive. This, in turn, endangers the species that depend on these ecosystems for survival.
Reports indicate that up to 51 million tons of plastic leak into nature, with 13 million tons spilling into the oceans. Hundreds of thousands of marine animals are reportedly killed by plastic each year. A popular prediction suggests that by 2050, our oceans and seas may contain more plastic than water.
The impact of plastic pollution extends beyond the visible, as microplastics further contaminate our soil, water, and food. A study published in the Proceedings of the Royal Society notes that terrestrial microplastic pollution has decreased species that live below the surface, such as mites, larvae, and other tiny creatures essential for maintaining soil fertility.
Moreover, chlorinated plastic can release harmful chemicals into the surrounding soil, which can then seep into groundwater or other nearby water sources, further contaminating ecosystems. This can have potentially harmful effects on the species that depend on these water sources.
