Tropical deforestation
* is currently a significant environment and development issue.
* occurs for a number of reasons.

Deletion
* Describe the kind of mutation that is called a 'deletion'.
* Most deletions affect expression
  - are terminal, vary in extent, and remove a gene for myelin basic protein
* Some deletions become so large that they are visible on well stretched metaphase chromosomes.
  * rationale no longer applies.
  * A couple of things, first off when you submit something to the wiki it gives a warning at the bottom of the page to not submit if you do not consent to have your content edited in any way. Deletion form of editing. Secondly, this is simple.wikipedia. Are you sure your article wasn't at english.wikipedia. If this is the case that is probably why you cannot access your account.
  * is one option, but there are always alternatives.
* are genetically devastating because of their permanence
  - removals
* can also cause frameshift mutations
  - occur in different parts of the gene and can be almost any size
* have effects
  - opposite effects
* is redaction
  - the type of mutation most frequently caused by radiation
* occurs when a portion of a chromosome is lost.
* provide valuable clues to the location of genes on chromosomes.
* range in size up to several centiMorgans.

Denudation
* is where weathering and erosion wears away and lowers the rocks and land.
* therefore acts to lower all continental surfaces to a flat featureless landscape.

Dermabrasion
* also leaves severe scarring and the pigment usually seeps back
  - produces a lot of bleeding
* are removals.
* is achieved by sanding the skin with a power sander
  - considered good for the improvement of acne scars
* is the sanding of scars and the smoothing of skin scarred by acne or other conditions
  - off of the outer layers of skin
  - used for improving scars and fine wrinkles
  - when a surgeon sands the skin to remove the pigment
* procedure used to level uneven areas of face.
* removes the upper layers of skin with an electric burr.
* revitalizing treatment that can reverse the outward signs of aging.
* scrapes off the outer layers of skin, but gives similar results to laser treatment.
* surgical technique where by some deeper scars and wrinkles can be smoothed.
* treatment that involves physically scraping off the top layer of skin.
* uses a high-speed, rotating brush to remove the top layer of skin.

Drainage
* are an often-used path of travel.
* carved by glaciers form steep canyons that open into the valley floor.
* ditches that fill during storms
  - traverse open fields are likely spots for bucks to use on opening day
* has effects
  - impact
* has indirect effects
  - negative effects
* is also a technique used extensively by farmers
  - an evacuation
  - another important factor in the growing process of vegetables
* is caused by construction
  - road construction
  - critical to the health of a cactus plant's root system
  - important to forest roads
  - inhibites by the natural healing process
  - key to healthy plants and herbs
  - only a small quantity of sanitary wastewater
  - slow, since water and nutrients move through the pore spaces slowly
* is the ease of removing water from pulp fibers, either by gravity or mechanical means
  - removal of excess water from the soil
  - used to a greater extent in Ontario and Quebec on soils that have poor natural drainage

### action | separation | removal | drainage:

Acid drainage
* can and does occur naturally at specific sites.
* is water containing acidity, iron, manganese, aluminum, and other metals.

Artificial drainage
* can help increase the number of trafficable days on poorly drained soil.
* is the weapon against salinization
  - used to increase aeration to the roots of growing plants
