Microorganisms as Eco-Engineers in Mitigating Global Warming: A Short Review from Bangladesh Perspective

Abstract

Microorganisms are the unseen architects of our ecosystems. They are the key players in maintaining the ecological balance through nutrient cycling, waste degradation, bioremediation, and even climate regulation. Microbes control the greenhouse gas flux by consuming and producing CO2, CH4, and NO2 during their metabolic processes. They also protect plants from abiotic stress via carbon sequestration. Thus, microbes help safeguard both the atmosphere and life. To better understand and leverage this microbial contribution to combat climate change, biostimulants and other strategic environmental interventions must be improved with a suitable climate model and policy framework. Especially in Bangladesh, where climate vulnerability is high and heatwaves strike more frequently, using microbial resources can significantly enhance resilience. This review outlines the major roles of microorganisms as eco-engineers, examining recent studies and developments that emphasize their importance in ecosystems and in reducing greenhouse gases.
