Environmental science is basically an interdisciplinary field that analyses physical, informational and biological sciences (including physics, zoology, chemistry, biology, ecology, physical geography, soil science, plant science, mineralogy, atmospheric science, and oceanography) for studying the environment and seeking solutions to environmental issues and problems. Today, it offers a quantitative, interdisciplinary and integrated approach towards studying the systems of the environment.
Environmental Science gives us an overview of the ways in which science affects the environment we live in. It focuses on the interactions between the Earth, its air, its air and also its living organisms as well as on interdependent, dynamic relationships between the four components mentioned above.
The job of environmental scientists
Scientists researching on earth and environmental science take into account how these different relationships affect our environment and change it at varied timescales. For doing this, they combine models, methods knowledge gathered from physics, biology, chemistry, and geology. They conduct researches to control, identify and eliminate hazards that disrupt the ecological balance and affect the lives of living organisms. Some environmental scientists also take care of environmental problems that affect human health.
Geologists, on the other hand, aim to understand our planet’s history. They try to foresee how processes and events of the past can influence the future of the earth and its creatures.
Components of the environmental science
These are the main components of the earth and environmental science:
- Ecology- Ecology is basically the study of the way in which organisms interact with each other and with the environment. Ecologists investigate the connection between organisms and physical characteristics of the environment, for instance, a chemical’s concentration. They might also investigate the connection between two populations of multiple organisms through some competitive or symbiotic relationship.
- Atmospheric sciences- Atmospheric sciences always focus on the atmosphere of the earth, with additional emphasis on the interrelation of atmospheric sciences to several other systems. Atmospheric sciences include research studies of greenhouse gases, meteorology, sound propagation, noise pollution, and light pollution.
- Geosciences- Geosciences mainly include environmental geology, volcanic phenomena, the earth’s crust’s evolution and soil science of our environment. In some systems of classification, geosciences also include oceanography and hydrology.
As an instance, we may cite the example of soil erosion. While studying soil erosion, soil scientists make calculations based on surface runoff. Fluvial geomorphologists play their role by examining the overland flow’s sediment transport. Physicists contribute by assessing the alterations in light transmission. Biologists analyze impacts to aquatic fauna and flora from enhancements in water turbidity.
- Environmental chemistry- Environmental chemistry is nothing but the study of the environment’s chemical alterations. Principal areas of this study include water pollution and also soil contamination.
This was all about the environmental sciences and their necessity on the earth. In Wales and England the EA (Environment Agency), established in the year 1996, is a body that protects and improves our environment and enforces certain regulations listed on the sites of the local government and the communities. The agency abides by the principles of the Environment Act of 1995. The nations need to start more environment-centric movements and organizations for the sake of the environment.
