Natural resources are raw materials we use to make other products.
These include trees, minerals, aquatic life, gravel, coal, and many
others. How can businesses remove these resources from an area and
still maintain a working landscape? Responsible businesses know that
they can make money producing products or gathering natural resources
while they minimize the damage to their surroundings. Take a look
at some products and possible damage from forestry, mining, and aquaculture.
Forestry
The forest industry is made up of businesses involved in the growing
and harvesting of trees and other plant life from forests.
| Products |
Damages |
| wood products |
They provide
lumber or timber for building houses, boats, decks, and furniture. |
clearcutting
|
Removing
a large block of trees exposes ground, which is vulnerable to
soil erosion. |
| paper |
They create
pulp to make paper and paper products. |
log jams
|
Over cutting
may result in logs piling up and blocking the natural flow of
water. |
| Christmas
trees |
They grow,
cut, and sell Christmas trees. |
lost recreational
value |
Forest
landscapes are degraded. Who wants to visit a forest with no
trees, or a river clogged with trees? |
| landscaping
|
They fulfill
our landscaping needs with trees and plants. |
lost renewable
resource |
New trees
may not be planted. Forests are not renewable resources unless
trees are planted to replace the trees cut down. This also displaces
wildlife. |
Mining
Mining is the process
or business of removing ore, soil, rock, and minerals from the ground
or from mountains.
| Products |
Damages |
| Coins |
Historically
and currently used as money. |
Reclamation
Reclamation means restoring land that has been altered. Mining
pits must be reclaimed after mining operations cease. Poor
mining practices can destroy the environment and cost taxpayers
a lot of money in clean-up.
Habitat
destruction
Animal habitats are destroyed and biodiversity is compromised.
Pollution
Mining by-products, called tailings, can pollute our air and
water.

Standards |

the value of currency. |
| Fossil
Fuels |
Provide
fuel by burning. |
| Nutrition |
Minerals
are often used in vitamins. |
| Building
Materials |
Provide
materials used in construction like aluminum and concrete. |
| Jewelry |
Gold, silver,
diamonds and other precious stones provide material for jewelry. |
| Gravel |
Gravel
is used to build roads and is mixed into cement to form concrete.
|
Aquaculture
Aquaculture is the business of raising marine or freshwater fish
or shellfish under controlled conditions.
| Products |
Damages |
|
Oyster
|
Netpens
Areas of waterways that are lined off by nets; these result
in large quantities of waste (just like other forms of intensive
animal production).
Aquaculture Waste
Processing wastes are often released directly into natural
bodies of water.
Protein
Many fish are carnivorousthey eat meat. The food provided
in fish farms may not contain meat protein. The fish who eat
this food do not possess the same amount of protein as their
natural counterparts. This can result in a less healthy fish.
Mangroves
Fishing operations (shrimp farms in particular) have damaged
mangrovestrees and shrubs forming buffering boundaries
between land and saltwater environments. (This is an important
ecosystem along coastlines.)

Making Commercial
Uses a Part of a Working Landscape
Trees can be replanted every time trees are removed. Paper and aluminum
can be recycled. Recycled materials can be used in place of lumber
for building materials.
Mining
businesses can devote some of their profits to the reclamation of
landscapes they damage.
A
wide variety of technologies and practices are available to make
aquaculture facilities more environmentally friendly, and many of
these are now used on commercial fish farms.
Sustainable use of natural resources such as forest harvesting,
mining, and aquaculture considers the economic, ecological, and
social elements that are part of a working landscape.

Mining
the Missing Loess Hill
Mining,
for fill dirt and limestone, is a controversial topic in the Loess
Hills. Most residents believe the heart of the Hills is the front
facethe west side. It's the most visible and the most fragile.
