The rising levels of carbon dioxide (CO2) in the atmosphere, driven by fossil fuel combustion, deforestation, and unregulated agricultural expansion, are having dire consequences for the oceans. Experts warn that marine waters are becoming increasingly acidic, surpassing safe limits necessary for sustaining marine ecosystems. This alarming trend has been highlighted by Professor Alexander Turra from the Oceanographic Institute of the University of São Paulo, who underscores the often invisible but potentially devastating effects of ocean acidification.

Professor Turra elaborates that the ongoing decrease in the pH of seawater, which measures acidity, neutrality, or alkalinity, indicates a worrying trajectory for marine biodiversity. Species that rely on a stable and balanced aquatic environment are at risk as the acidification interferes with crucial behaviors and biological functions, including the hearing abilities of fish. This represents not only a threat to individual species but could also disrupt entire food chains and marine habitats if left unaddressed.

The implications of these findings extend beyond the local scale, as the impact of ocean acidification is a global issue, stressing the need for urgent action on climate change and pollution control. The degradation of marine ecosystems has far-reaching consequences for human economies, predominantly in coastal regions that depend heavily on fishing and tourism. Addressing the sources of CO2 emissions is essential to mitigating this crisis and ensuring the health of our oceans for future generations.
