Environmental Science for Students provides a fascinating look at Earth's
environment and some of the most important environmental issues of our time. From
the quality of the air that we breathe and water that we drink to the lasting effects
of our reliance upon fossil fuels to power our lives, everyone is affected by
environmental change. Accurate explanations, global examples and balanced viewpoints
guide students in an exploration of topics that range from global climate change to
the degradation of soil. Environmental experts speak about topics of interest and
noteworthy case studies showcase real-world examples. The environment's link to human
health, the economy and society is also examined, making clear the interconnected nature
of these components. This series will help students to understand the science behind
their changing world while considering multiple perspectives.

Do you know the quality of the air that you breathe? Air pollution
from both natural sources and human activity can affect humans, plants
and animals in many ways. Learn about primary and secondary sources of
air pollution, explore how outdoor air quality is monitored by government
agencies and see how climate, geography, industry, automobiles and other
factors can contribute to the formation of photochemical smog. Does your
community face air quality issues? The enormous challenge of regulating
and reducing air pollution can be tackled at local, national and
international levels. From green roofs to the Clean Air Act to the
Kyoto Protocol, improving air quality in one part of the world can
have a positive effect the world over.

Dive into an in-depth exploration of global climate change, and see how
both natural events and human activity, particularly since the Industrial
Revolution, have played a role in changing our climate. See how climate data
is collected, learn about the role of the greenhouse effect and discover some
familiar and some unexpected sources of greenhouse gases. Consider experts
views on the potential effects of global warming－from relatively mild changes
in the weather to more extreme scenarios, such as intense storms, warming oceans
and melting ice caps. Investigate efforts to combat climate change at international,
national and local levels. Weigh the effects of these efforts and consider what else
can be done because the fact remains that global climate change could possibly be one
of the most important issues of the 21st century!

Energy has powered the advancement of civilizations and the growth of technology
throughout history－from the nonrenewable energy sources that helped to power the
Industrial Revolution to the utilization of renewable energy sources. Discover what
green energy is and learn about its potential to meet our energy needs in an ongoing,
sustainable way. Green energy includes solar power, wind turbines, biomass fuels and
much more. Some forms of green energy are more suited to certain locations than others.
Observe how geothermal energy helps to power much of ReykjavÍk, Iceland, and see elements
of green energy, sustainable design and conservation in action at the headquarters of the
Chesapeake Bay Foundation in Maryland. From the choices and efforts of an individual to
that of an entire city, rethinking where we get our energy and how we use it is important
in ensuring that energy needs of future generations will be met.

Although soil may seem plentiful, it can be polluted and depleted by natural and
human activities. Examine sources of soil pollution and discover some of the efforts
taken to prevent this, such the construction of sanitary landfills and the long-term
storage of hazardous waste. Visit Love Canal, an area dramatically affected by soil
pollution, and see the state of that community today. Although soil erosion is natural
and necessary, human activity can hasten and magnify this process. Learn how “America's
Bread Basket” was transformed into the “Dust Bowl” during the 1930s, and see what farming
methods have been implemented as result. Finally, travel to Shirley Plantation in Virginia,
and observe how several ambitious projects have reclaimed degraded land to transform
potential wastelands into valuable farmlands. Soil is much more than dirt beneath our feet.
It is an essential component of life on Earth.

Sustainability refers to the capacity to provide for the needs of the world's
current population without harming the ability of future generations to provide
for themselves. Explore some of the challenges and successes of sustainability
starting in one of the world's most diverse habitats－the rainforest. Then,
consider some factors that can affect sustainability: carrying capacity,
population density and ecological footprint. Weigh the impact of suburban
sprawl, and visit Portland, Oregon, to see how this city has worked to
combat sprawl through smart-growth policies. Observe sustainability in
action at a school that has employed green building practices － from their
playing field made from recycled plastic and rubber tires to the photovoltaic
panels on the roof. By studying and understanding the idea of sustainability
and putting that concept into practice, we can begin working toward building a
responsible and sustainable future.

More than two-thirds of the planet is covered by water. Because water is vital
to all life, both the quality and availability of this precious nature resource
is critical. Investigate point and nonpoint sources of pollution, consider the
potential environmental, economic and health effects of water pollution, and
see what scientists look for when they test the water quality of North America's
largest estuary－the Chesapeake Bay! When the supply of available fresh water is
overused, polluted or affected by climate change, a whole new problem arises－water
scarcity. Learn what can happen when an area's water supply dwindles, and see how
conservation and innovation can help to combat this problem. From the passing of
the Clean Water Act in 1972 to the building of desalination plants, discover some
of the tremendous strides that have been made in maintaining the quality and quantity
of the world's water supply.
