Marine ecosystems face rising threats from warming, pollution, and invasive species

marine pollution microplastics invasive species ocean warming tourism threat

Global marine environments are facing multiple critical threats, including record-breaking temperatures, invasive species, and severe plastic pollution.

According to the Copernicus climate service, global sea surface temperatures reached a record high of 21.1 degrees Celsius on August 22, 2026. This warming trend is linked to an increase in marine heatwaves, which have tripled in frequency since the 1990s.

In the Mediterranean, scientists are warning of a state of emergency due to critical microplastic levels. Research conducted along the Alanya coast in Turkey suggests that over 140 recycling plants in the Adana and Mersin regions are contributing to waste that enters the sea via rivers. This pollution threatens the region's multi-billion dollar tourism industry.

Additionally, the invasive Quagga mussel, originating from the Black Sea, is spreading through Bavarian lakes in Germany. Experts warn that once established, the species is nearly impossible to remove. The mussels disrupt local ecosystems by consuming massive amounts of plankton and can cause economic damage by clogging drinking water pipes.
