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.

what do you think would happen if all of
the trees in the rainforest were cut
down or if chemicals were spilled in a
river or if snow and rainfall increased
drastically these are some of the many
topics that are studied in the field of
environmental science overall
environmental science is the field of
science that studies the interactions of
the physical chemical and biological
components of the environment and also
the relationships and effects of these
components with the organisms in the
environment the field of environmental
science can be divided into three main
goals which are to learn how the natural
world Works to understand how we as
humans interact with the environment and
also to determine how we affect the
environment the third goal of
determining how humans affect the
environment also includes finding ways
to deal with these effects on the
environment environmental science is
also referred to as an interdisciplinary
field because it incorporates
information and ideas from multiple
disciplines within the Natural Sciences
such Fields as biology chemistry and
geology are included in environmental
science when most people think of
environmental science they think of
these Natural Science aspects but what
makes environmental science such a
complex and Broad field is that it also
includes fields from the social sciences
and the humanities the social science
fields that are incorporated into
environmental science include geography
economics and political science
philosophy and ethics are the two Fields
within the humanities that are also
included in environmental
science by combining aspects of the
Natural Sciences social sciences and the
humanities the field of environmental
science can cover more Concepts and also
examine problems and topics from many
different points of view
at this current time the world around us
is changing at a very rapid Pace some
changes are beneficial but many of the
changes are causing damage to our planet
the field of environmental science is a
valuable resource for learning more
about these changes and how they affect
the world we live in let's examine a
major change that is currently occurring
and its relationship to environmental
science the large change is the dramatic
increase in the number of humans on
Earth for most of human history the
population has been less than a million
people but the current population has
skyrocketed to over 7 billion people
this equals out to 7,000 times more
people due to this increase in the human
population there has also been an
increase in pressure on the natural
resources and ecosystem services that we
rely on for
survival natural resources include a
variety of substances and energy sources
that we take from the environment and
use natural resources can be divided
into renewable and non-renewable
resources renewable natural resources
are substances that can be replenished
over a period of time such as sunlight
wind soil and Timber on the other hand
non-renewable natural resources are
substances that are in finite Supply and
will run out non-renewable resources
include minerals and crud oils due to
the increase in the human population
natural resources are being used up at a
more rapid rate than in the past
although renewable natural resources can
be replenished when they are used too
rapidly they cannot be replenished fast
enough to meet human demand even worse
when non-renewable natural resources are
used too rapidly they become closer to
running out completely and being gone
forever natural resources have been
referred to as the merchandise produced
by the environment and in this respect e
