Explanation:
Environmental science can be defined as an interdisciplinary field of science that comprises of chemistry, economics, engineering, zoology, geography, geology, biology, ecology, physics, etc., used for the study and understanding of various environmental factors, issues in relation to human life.
Our understanding of both biology and geology is based on the idea that living things and environments have changed slowly, over billions of years.
This understanding is made possible through the study of the relationship between living organisms and their environment, as well with other forms of life found in the ecosystem.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Basically, scientist have been able to study the remains of various living organisms (fossils) from billions of years ago and discovered that the change between the living organisms and the environment occured slowly.
