What is Environmental Science? Definition and Scope of the Field

Summary

Environmental science is a multidisciplinary field that examines the interactions between physical, chemical, and biological components of the environment and their effects on organisms. It aims to understand the natural world, human interaction with it, and the impacts we have. As the human population surges to over 7 billion, the strain on natural resources, both renewable and non-renewable, intensifies. This field is crucial in addressing the rapid changes affecting our planet, offering insights into sustainable management and conservation.

Q & A

What is environmental science?

Environmental science is the field of science that studies the interactions of the physical, chemical, and biological components of the environment, as well as the relationships and effects of these components with the organisms in the environment.

What are the three main goals of environmental science?

The three main goals of environmental science are to learn how the natural world works, to understand how humans interact with the environment, and to determine how humans affect the environment, including finding ways to deal with these effects.

Why is environmental science considered an interdisciplinary field?

Environmental science is considered an interdisciplinary field because it incorporates information and ideas from multiple disciplines within the natural sciences, social sciences, and humanities.

Which natural science fields are included in environmental science?

Fields such as biology, chemistry, and geology are included in environmental science as part of the natural sciences.

Which social science and humanities fields are incorporated into environmental science?

Social science fields like geography, economics, and political science, and humanities fields such as philosophy and ethics are incorporated into environmental science.

How does the rapid pace of change in the world impact environmental science?

The rapid pace of change in the world, both beneficial and damaging, makes environmental science a valuable resource for learning more about these changes and how they affect the world we live in.

What is the relationship between the increase in human population and environmental science?

The increase in human population leads to increased pressure on natural resources and ecosystem services, which is a significant area of study within environmental science.

What are natural resources and how are they categorized?

Natural resources are substances and energy sources taken from the environment and used by humans. They are categorized into renewable resources, which can be replenished over time, and non-renewable resources, which are in finite supply.

Why are renewable natural resources still at risk despite being replenishable?

Renewable natural resources are at risk because they are being used up at a more rapid rate than they can be replenished, which cannot keep up with the high human demand.

What are the consequences of using non-renewable natural resources too rapidly?

Using non-renewable natural resources too rapidly brings them closer to running out completely and being gone forever.

How have natural resources been described in relation to the environment?

Natural resources have been referred to as the 'merchandise produced by the environment,' highlighting their role as products of natural processes.
