The diverse discipline of environmental science is dedicated to examining how people and the environment interact. Modern techniques to solve complicated environmental concerns and encourage sustainable practises have arisen as a result of the increasing awareness of environmental difficulties. In order to solve environmental issues, this study presents an overview of several contemporary environmental science methodologies. Remote sensing, Geographic Information Systems (GIS), environmental modelling, and sustainable technology are some of the techniques covered. Effective environmental management strategies have resulted from the adoption of these methodologies, which have permitted enhanced data collecting, analysis, and decision-making processes. Additionally, these techniques have helped us better understand ecological systems, foresee environmental effects, and develop mitigation strategies. Modern approaches in environmental science play a critical part in creating environmental sustainability and a brighter future for our planet by using the power of technology and scientific discoveries.
