In every new sample we analyze – the amount of plastic fibers and fragments approaches – and often surpasses – that of the planktonic organisms themselves.

From our field laboratories and aboard the research vessels Triton and Aegean Explorer, we have been recording the levels of plastic and microplastic pollution in Greek seas for 15 years. What we must share with you is that the presence of microplastic fibers and plastic fragments in the samples we collect and analyze has skyrocketed – especially in recent days, following the heavy rainfall.

In a world that continues to feed the sea with waste, while legislation on waste management and plastic reduction remains more a matter of communication than action, the upward trend of plastic pollution —- both visible and invisible — has become increasingly stark and alarming. In many cases, the changes are noticeable from one day to the next.

As we also study the biodiversity and abundance of zooplankton — the microscopic organisms forming the foundation of marine life — it is deeply troubling to find that, in every new sample, the amount of plastic fibers and fragments approaches, and often exceeds, that of the planktonic organisms themselves.

In the coming days, we expect a peak in our readings, as rainfall washes plastics from every corner of the land — from streets, squares, archaeological sites, tourist areas, and open fields — straight into the sea.

Whatever we scatter across the land inevitably ends up in the sea; and with each passing day, we are contributing to a growing environmental crisis that will affect both future generations and marine
ecosystems.
