Design for the Environment “Dfe” is the concept of including
environmental considerations in manufacturing and construction. Both design and redesign of products and systems are included.

Design for the Environment Business leaders are encouraged to
consider the environment when making decisions about: Product design-possible environmental
impact? Materials- using environmentally friendly
materials? Purchases- buying materials either recycled
or recyclable, and produced with minimum environmental impact?

Life Needs 1. Food2. Water3. Air 4. Space 5. Shelter & Protection
![Page 8: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/8.jpg)
Life Needs: Food Material consumed and needed to carry
out life processes Nutrient is a substance needed for an
organism to live and grow Ex) Proteins, carbohydrates, fats, minerals
and vitamins
![Page 9: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/9.jpg)
Life Needs: Water Essential for all of life’s processes Humans need about 2 quarts per day
![Page 10: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/10.jpg)
Life Needs: Air All living things need some part of air to
survive Animals need oxygen & plants need carbon
dioxide Respiration is the process an organism uses
to provide its cell with oxygen so energy can be released from digested foods
Plants provide oxygen for animals, and animals provide carbon dioxide for plants, thus the relationship is interdependent.

Life Needs: Space All living organisms need and occupy
space Space is the area around an organism
that is used for living Territory is the area an animal used
and protects as its own
![Page 12: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/12.jpg)
Life Needs: Shelter & Protection Organisms need protection from certain
elements in the environment that can injure or destroy them
Some animals adapt, some hibernate and some migrate
Plants generally only grow in an environment that is suited to them
![Page 13: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/13.jpg)
Roles of Humans Humans have three major roles in
maintaining the quality of the environment…1. Users- humans use the resource to support
life functions2. Decision makers- humans decide which
resources are used, and how they are used3. Conservationists- humans can prevent
waste. Humans should not be an abuser of the environment.

The Environment as Home Every living organism requires an
environment that sustains life Ecosystem: a natural environment has
many ecosystems, which are all components of a particular environment
Habitat: the physical area where a plant or animal lives under natural conditions Proper arrangement of 4 essential
elements: food, water, shelter, and space
![Page 17: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/17.jpg)
Energy Transfer Ecosystems need energy to exist Energy is the ability to be active and do work An ecosystem has a complex process for
transferring energy that originates from the sun to organisms, specifically from one organism to another
Food Chain is the ranking of species into successive levels where each feeds on the one below
Food Web is all the interconnected food chains of an ecosystem

Conservation VS. Preservation Conservation: Wise use of a natural
resource Prevent unnecessary damage/loss
Preservation: Nonuse of a natural resource
![Page 19: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/19.jpg)
Human Effects on the Environment Can have positive & negative effects on
environment Symbiotic relationship
Different species of organisms live together and benefit each other
Debated issue One problem…humans give little thought
to the resources they use each day, including where the resource came from, and where it ends up
![Page 20: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/20.jpg)
Planning Ahead Humans must plan to preserve and
protect our resources 1. Human Impact2. Chemicals are not always bad 3. Maintaining Habitats 4. Abuse of Resources 5. Conservation Measures
![Page 21: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/21.jpg)
Human Impact Humans affect all natural resources Often, we only consider the aesthetic
benefits Plants not only have aesthetic value, but
keep hot areas cooler and provide shelter from winds as well
![Page 22: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/22.jpg)
Chemicals are not always bad… For example, fertilizer
Provides nutrients for plant growth Problems come from overuse or misuse One chemical that caused
environmental problems is the insecticide DDT. The major problem with it was that it did not break down and, therefore; it accumulated in the food chains
![Page 23: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/23.jpg)
Maintaining Habitats The major affect humans have had on
the environment has been habitat destruction
Resource most effected=wildlife Some species can adapt to changes in
their habitat
![Page 24: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/24.jpg)
Abuse of Resources When resources are abused, they are
depleted
![Page 25: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/25.jpg)
Conservation Measures Many conservation measures have be
put in place Measures must be proven not only for
conservation of the resource, but for economic and productive purposes as well Example) Flow restrictor on a
showerhead…saves $$ and conserves water
![Page 26: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/26.jpg)
Developing Personal Beliefs About the Environment How one feels about the environment is
influenced by: Age Gender Culture Education Other factors
Become properly and thoroughly informed from various sources

Human Population Growth World population is “exploding”
More people being born, living longer, wanting more things
Increase in demand for life’s necessities Currently 6.2 billion people US=284 million people NC=8,050,000 (11th in the nation)
![Page 28: Sustainability & Conservation Obj: Discuss the importance of sustainability and conservation in relation to humans](https://reader035.vdocuments.us/reader035/viewer/2022062423/56649ed95503460f94be7728/html5/thumbnails/28.jpg)
