What is Environmental Science
⦿Human population dynamics such as population pressure, economic development are the primary drivers of environmental change.
⦿The environmental science emphasise on the need for equitable, ethical, and sustainable use of Earth’s resources by a global population that nears the carrying capacity of the planet.
⦿Emissions generated by human activity continue to alter the composition of the atmosphere, leading to air pollution, climate change, stratospheric ozone depletion and exposure to persistent, bioaccumulative and toxic chemicals.
⦿Environmnetal Science enables us not only to understand how human behaviors affect the environment, but also the scientific principles that govern interactions between the living and non-living.
⦿The word ‘environment’ is most commonly used to describe nature and means the sum of all living and non-living things surrounding an organism or group of organisms.
⦿The environment includes all elements, factors, and conditions that impact the growth and development of certain organisms.
⦿The environment includes biotic (all surrounding living organisms) and abiotic factors (light, temperature, water, atmospheric gases that influence observed organisms.
⦿The environment is the total of all the conditions (physical, chemical, biological, social, cultural, and economic) surrounding the human being at a given point in space and
time.
⦿The term ‘Environment’ is used for surroundings and is derived from French word ‘environ’ or ‘environner,’ which means around or encircle or surroundings.
⦿The environment may be defined as the complex of climatic, biotic, social, and edaphic factors that act upon an organism and determines its form and survival.
⦿The environment provides resources that support life on the earth and help in the growth of a relationship between living organisms and nature.
⦿The environmental science can be defined as “an interdisciplinary study of how the Earth works, how we are affecting the Earth’s life-support systems (Environment), and how to deal with the environmental problem we face”.
⦿The environmental science is the study of the human impact on the physical and biological environment of an organism. The environment in which we live has been irreversibly affected by advancements in technology, and it has been affected for as long as humans have wielded tools to alter their circumstances.
