Ocean and human health

Introduction

The World Health Organization (WHO) has identified the ten most pressing health threats the global public is facing today. These threats include widespread non-communicable diseases like cancer, diabetes, and heart disease, alongside dangerous infections such as influenza, Ebola, dengue, and HIV. Particularly concerning is the rise of high-threat pathogens and antimicrobial resistance (AMR). As conventional treatments are proving to be inadequate, the need for innovative and multidisciplinary solutions is becoming increasingly vital.

Antimicrobial resistance (AMR) stands out as one of the most urgent challenges, being linked to 4.95 million deaths worldwide in 2019, with bacterial AMR causing 1.27 million deaths. The effectiveness of existing antibiotics is diminishing, as biofilms- matrices of microbial aggregates- have developed intricate and diverse resistance mechanisms against current treatments. While the urgent need for novel antibiotics is clear, their discovery and development have declined in recent years.

Marine environments, with their vast biodiversity, offer a promising solution to this pressing challenge. Marine natural products have emerged as a valuable source of novel bioactive compounds with unique mechanisms of action that can potentially overcome existing therapeutic limitations. Marine natural products' unique chemical structures and bioactive properties have evolved due to harsh marine conditions and evolutionary pressures. The ongoing exploration of marine biodiversity and natural compounds is an essential part of the global effort to combat today’s most critical public health threats.
