Abstract

Future importance of healthy oceans: Ecosystem functions and biodiversity, marine pollution, carbon sequestration, ecosystem goods and services

Highlights

  • Earth’s nickname “The Blue Planet” derives from the fact that oceans cover two-thirds of the surface of earth

  • Hossain: Future importance of healthy oceans systems are not put in place to save the coastal and Marine environment from the pollution which will be created from these economic zones

  • Since it is expected that the plastic pollutants in the ocean will become one third of the total Ocean biomass in near future, the situation will be greater in the case of Bay of Bengal since the countries in this region are amongst the largest release year of plastic pollutants into Bay of Bengal Large Marine Ecosystem (BOBLME) ecosystem

Summary

INTRODUCTION

Earth’s nickname “The Blue Planet” derives from the fact that oceans cover two-thirds of the surface of earth. The sustainable future of mankind depends largely on the dramatic reduction of influx of pollutants into them and to maintain the biodiversity therein for sustenance of ecosystem services from them (“Classification of marine ecosystem services,” 2016; Palumbi et al, 2009; Sultan, n.d.; United Nations, 2017). This importance is manifested from the declaration of sustainable development goals (SDGs) as Goal 14 explicitly call to “Conserve and sustainably use the oceans, seas and marine resources for sustainable development” and outlined 7 main and 3 associated targets in order to attain the goal (Neumann et al, 2017; Vierros, 2017).
