Human Impact: How It Works A Survey You are assigned one aspect of human impact to investigate and report on.

You will report on your investigations in the frame that has your aspect as a title. What you can do:
Include all of the information/items required (really, you have to do that).
Change colors, font orientations, select from the three font options in the text window.
Insert any shapes, lines, arrows, etc., as necessary.
Move and resize any elements in your frame. You must include:
A description of what the impact is, and its cause.

Can also be snow, fog, water vapor, or dry material that settle on earth. -Air Quality is unwanted gaseous amounts of high quantities in the atmosphere population crashes exploitation of wild populations for food -Causes can include burning fossil fuels, such as industrial plants http://www.urbanheatislands.com/
http://www.weatherquestions.com/What_is_the_urban_heat_island.htm Light Pollution is the result of bad lighting design, which allows artificial lights to shine upward and outward into the sky, where it is now wanted, instead of focusing it downward, where it is. Poorly designed lighting washes out the darkness of night and radically alters the light levels and light rhythms to which many forms of life have adapted. Wherever human light spills into the earth some aspect of life is affected. In a simpler explanation, Light Pollution affects how the sky looks. The removal of trees and forested areas from
the Earth. The main cause of this is all related to money. http://www.livestrong.com/article/170951-the-causes-effects-solutions-for-air-pollution/
-low air quality can create harmful chemicals such as smog and acid rain. habitat destruction The Picture to the left show a great example of Light Pollution. The left half of picture is the sky not affected by Light Pollution. The right half is the sky when it is affected by Light Pollution. As you can tell there is a huge difference between the two. Humans burn fossil fuels, sulfur dioxide and nitrogen oxides are released into the atmosphere. These chemical gases react with water, oxygen, and other substances to form solutions of sulfuric and nitric acid. Winds can spread these acidic solutions across the atmosphere and over hundreds of miles. When acid rain reaches Earth, it flows across the surface in runoff water, enters water systems, and sinks into the soil. Pictures impact Loss of habitat for animals
Global warming
Dramatic weather changes -carbon monoxide, sulfur dioxide and nitrogen oxide react with the sun Text minimize waste http://www.epa.gov/hiri/about/index.htm -creates greenhouse effect -no room for places to grow Acid rain makes waters acidic and causes them to absorb the aluminum that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals. Those animals that aren't directly effected are indirectly effected by the impact on the food chain.
Acid rain also damages forests, especially those at higher elevations. It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees and plants to take up water, less able to withstand cold temperatures, insects, and disease, and affects their ability to reproduce -ozone layer serves as a filter limiting the sun’s ultraviolet Urban Heat Islands are the result of areas with high pavement heating up more quickly than the vegetation in rural areas. -limited resources for a community http://ngm.nationalgeographic.com/2008/11/light-pollution/klinkenborg-text

•It is caused by ozone depleting substances like CFCs. CFCs are chlorofluorocarbons, things like paints, hairspray, perfumes and many other household products. Consumerism is the purchasing

Ex.: In a light polluted site, birds are continuously chirping throughout the night, in anticipation of a dawn that will not arrive for many hours. http://environment.nationalgeographic.com/environment/global-warming/acid-rain-overview/ The only way to stop acid rain is to stop the release of the pollutants that cause it which means using less fossil fuels. Many governments have tried to reduce the amount of fossil fuel used and have had mixed results.
Individuals can help stop the amount of pollutants by conserving energy in their homes and using vehicles less.
Even if we stopped pollutants today, it would take many years for all the harmful effects to disappear.

number of genetic characteristics
in the genetic makeup of a species.
It is caused by mating patterns,
distributions, and migration. In order to increase the diversity,
governments should ban poaching
and hunting of rare species of animals.
This would lower the death rates and
possibly help the species multiply,
causing a greater genetic diversity. Genetic diversity helps in natural
selection by eliminating negative
effects of inbred hybrids. The risk
of congenital disorders as a result
of mutation is gets minimized by
genetic diversity. •http://www.biology-online.org/dictionary/

Little natural resources used, much power created
"Breeder" reactors recycle used uranium to create plutonium
Creates nuclear waste, disposal methods disputed
Each country responsible for own waste
Low level waste (90% of all waste) contains 1% radioactivity
Stored in (shallow) underground repositories
Longer waste is stored, the easier it can be handled due to diminution of radiation
High level wastes require a cooling period of 50 years after removal from reactor core
Deep geological disposal is choice method for HLW
Waste containers buried miles into the crust and then placed into repositories
Waste per 1000 MWe is 1.96 meters cubed
No "safe" level of waste

Collection of Marine Debris, mostly plastic in the northern pacific
Located between the U.S. and Hawaii in a Sub tropical Gyre.
Trash gets traped in this vortex and can not escape so it accumulates over time
The plastic is 100% non-biodegradable so it is not going anywhere
Out of the 300 billion pounds of plastic produced a year, about 10% ends up in the ocean, 70% of which sinks to the bottom
The patch is two times larger than the size of texas Over a million sea-birds and one hundred-thousand sea mammals die from consuming plastic or entanglement.
Amount of plastic outnumbers the amount of planktin, which is the primary resource of the enviroment

Less spending on food and supplies that are not going to be used Pollinator Decline is the decline in the population of pollinator species such as bees, butterflies, moths, flies, beetles, hummingbirds, and even bats.
There are many different causes as to why Pollinator Decline is occuring.
+The Weather
+Habitat Loss
+Planting Large Areas of Crops that are unattractive to Pollinators
+Introduced pests and parasites
+Microbial diseases
+Pesticide Drift
*Declines in the pollinator population have been gradual, they didn't all disappear at once. +could damage dozens of commercially important crops
+approximately 3/4 of the 250,000+ species of flowering plants on the planet rely on pollinators to carry out this vital process-lose those plants in pollinator decline
+Pollinator population declines have been reported on no fewer than four continents.
+lose supplies of animal-pollinated foods—most fruit, vegetable, and nut crops, which provide the bulk of vitamins and other necessary nutrients in our diets
+They serve as keystone species in most terrestrial ecosystems. Allow plants to reproduce, which provide food and shelter for animals. In some areas, pollinator-supported plant communities prevent erosion by binding the soil—thereby conserving an important resource and keeping creeks clean for aquatic life.-Losing them loses much of the biodiversity in the ecosystem http://www.washingtonpost.com/wp-dyn/content/article/2006/10/18/AR2006101801712.html http://www7.nationalacademies.org/ocga/testimony/Colony_Collapse_Disorder_and_Pollinator_Decline.asp http://nebsusag.org/newsletters/feature56c.htm Honey Bee Colony Collapse Disorder (CCD) Pesticides and Decline In Pollinator Populations 1.help increase wild pollinator populations by creating attractive nesting sites for them

http://www.globalrestorationnetwork.org/uploads/files/LiteratureAttachments/368_what-is-habitat-fragmentation.pdf Reservoirs are large, un-natural lakes that are caused by upstream damming of a river. The reservoir waters spill out into the surrounding environments, creating floods.

These reservoirs are impacting the environment in many harmful ways. Reservoirs flood natural habitat that existed before the dam's construction and to date, over 400,000 km^2 of the earth have been flooded due to damming and the creation of reservoirs. -In some reservoirs, water mass at the bottom may become deoxygenated and unable to support life, although the surface may be well oxygenated. The tendancy for reservoirs to become deoxygenated is also accelerated in regions where there is a substantial input of nutrients from agricultrual fertilizers, animal wastes, or human sewage, either directly into the reservoir or into the river that feeds it. Deep reservoirs may become permanently de-oxygenated.

-Physical, chemical, and biological changes occur in the water stored in reservoirs also. Reservoirs act as a nutrient sink, storing much of the inflowing nitrogen and phosphorus in the sediment. Water discharged at a dam can be of different chemical composition which leads to a different seasonal pattern to that of the natural river.

-Reservoirs influence the temperature of the river. Water temperature is important for the assesement of impacts of a dam and reservoir on downstream aquatic habitats. Thermal changes may have signifigant effects on the living organisms in the river.

-Reservoirs also impact humans. The building of a dam and the creation of a large reservoir upstream can displace where humans live. Lake Sakakawea in North Dakota, which is the largest man-made lake in N.D. and the third largest in the United States, is an example of the displacement of humans. The creation of this lake displaced members of the Fort Berthold Indina Reservation from the cities of Van Hook, forcing the creation of New Town and Mandaree. www.internationalrivers.org
