Environmental science is The study of how humans
Interact with the environment.

The major focus of environmentalScience is to solve environmental
Problems that WE created!
The term environment refers To everything that
Surrounds us.

News reports area heard dailyThat sound the alarm of
Health risks from chemicals In the soil, water, and even in
The food that we eat.
Every informed citizen thinks About the changes in our
Environment.

Solving these problems can Become very complicated
And expensive.
This can be done though, The drinking water from
Lake Erie and the CuyahogaRiver are much better than
Even a few years ago.

Although there seems to be An unlimited number of
Environmental problems, They all fall into 3 categories…
Resource depletionPollution
And Extinction

Natural resources can be Considered as any natural
Substance that living things use.
Such as…Sunlight, air, water, Minerals, plants, and
Fossil fuels.
![Page 8: Environmental science is The study of how humans Interact with the environment.](https://reader030.fdocuments.net/reader030/viewer/2022032606/56649eb15503460f94bb6a89/html5/thumbnails/8.jpg)
A nonrenewable resource is Any resource that cannot
Be replaced.
A renewable resource is Just the opposite, those that
Are replaced.

Pollution is the introductionOf harmful levels of
Chemicals or waste materialInto the environment.
Scientists estimate that Thousands of species are
Becoming extinct every year.

Many environmental problems Are global problems.
Such as pollution released fromCoal power plants causes
Acid rain that falls everywhere.

The biosphere is the thin layerOf life that exists around
The Earth.
It is roughly 8 km above andBelow the Earth’s surface.
![Page 12: Environmental science is The study of how humans Interact with the environment.](https://reader030.fdocuments.net/reader030/viewer/2022032606/56649eb15503460f94bb6a89/html5/thumbnails/12.jpg)
No matter what country People live in, they are in
The biosphere.
A developed country is Highly industrialized and
Have high incomes.
Developing countries are lessIndustrialized and their citizens
Have much lower income, Like India - $2700 a year.

Many environmental problems Are linked to increasing
Human populations.
This leads to a population crisisAnd a consumption crisis.

There are 2 basic types Of science…
Pure sciences And
Applied sciences
![Page 16: Environmental science is The study of how humans Interact with the environment.](https://reader030.fdocuments.net/reader030/viewer/2022032606/56649eb15503460f94bb6a89/html5/thumbnails/16.jpg)
A pure science seeks to Answer questions about how
The natural world works.
An applied science usesInformation to solve problems.
Biology - Physics - Chemistry
Environmental – engineering

One of the most important Foundations of environmental
Science is ecology.
Ecologists study how living Things interact with each other
and their surroundings
