Hillary Clinton voted 95% rated among these environments at the LCV. I agree with the funding to stormwater cleanup and regulations on Mercury emissions but I don’t agree with what she said in reference to fuel economy, she wants to stifle the oil industry in new york by raising prices. Change will come but not overnight. The correct alternatives haven’t been developed properly.

The funnel metaphor shows demand and supply. The funnel is pinching at the moment and there is a diminishing amount of resources. Through innovation, creativity, and the unlimited potential for change, we can open the walls of the funnel. Supply and demand and innovation are the keys to this philosophy. Life may change if the innovations occur. The individual may have to give up certain privileges for a time but they should eventually return. This method doesn’t increase concentrations of substances extracted from the Earth, concentrations of substances produced by society, degradate by physical means and in that society people are not subject to conditions that systematically undermine their capacity to meet their needs. The textile industry is huge. If these methods were to be changed in current business, transportation will have to change or business will start have to focus closer to the country which is being sold too.

The issue at hand is taking advantage of compact building design. In summary, incorporating ideas of less land consumption in the building of structures will benefit the environment. It would be beneficial to build up instead of out. The more green, the better off the situation. This idea is more for urban development than anything else however it can be applicable to any area. Current zoning practices limit the use of compact building design. There is a size minimum on lots, along with community perceptions of higher density development both limit the use of this idea.
Actions of compact building design in the community is shown by Inderkum High School in Sacramento California. The building has been built higher and narrowed its perimeter. Sports fields are the public fields. We use the last idea in Watertown. IHC uses the Duffy Fairgrounds for baseball, soccer, and hockey.

chapter 20 questions for review

slofberg — Mon, 27 Mar 2006 01:55:06 +0000

1.) Drive less, take the stairs, insulate your house and add more insulation to the existing amount, turn thermostats down in the winter and up in the summer, eat locally grown food in season.

2.) Net energy yield is based on the total useful energy produced during the lifetime of an entire energy system minus the energy required to make useful energy available. Nuclear power, and hybrid cars are good examples.

3.) Active solar energy generally pumps a heat-absorbing, fluid medium through a relatively small collector, rather than passively collecting heat in a stationary medium like masonry. Passive uses natural materials or absorptive structures with no moving parts to simply gather and hold heat.

4.) Capture solar energy and convert it directly to electrical current by separating electrons from their parent atoms and accelerating them across a one way electrostatic barrier formed by the junction between two different types of semiconductor material.

5.) Fuel cells are devices that use ongoing electrochemical reactions to produce an electric current.

6.) Problems with burning wood in industry are the film it creates on things near the source, also the high amounts of carbon monoxide and hydrocarbons emitted.

7.) Methane is produced by anaerobic decomposition of any moist organic material. It is a fuel that burns efficiently.

8.) Hydroelectric dams are very efficient and don’t hurt the air, however they do affect water flow, and can damage aqueous habitats.

9.) Ethanol, methanol, and bio fluid.

10.) Tidal power or ocean wave power generate electricity by tidal stations’ turbines spinning as the tide flows through them.

chapter 17 questions for review

slofberg — Mon, 06 Mar 2006 23:34:34 +0000

1.) Withdrawal is the total amount of water taken from a lake, river, or aquifer for any purpose. Consumption is the fraction of withdrawn water that is lost in transmission, evaporation, absorption, chemical transformation, or otherwise made unavailable for as a result of human use. Degrading is polluting or heating so that it is unsuitable for other uses.

2.) Withdrawal of water in each section increases as time increases. Agriculture does this on a much larger level than domestic and industry but they are all in proportion. Trends show that withdrawal levels never meet consumption, they are always way higher.

3.) Places with the highest water irrigation are those lining the Mississippi River, and the Midwest.

4.) Some problems with damming and water diversion techniques are that they flood areas above the dam, drowning communities and graveyards. Other problems with dams are that they restrict the migratory patterns of indigenous fish who mate upstream.

5.) Water molecules would move by transpiration, it would evaporate and turn into a gaseous form. When it becomes humid enough and there is enough pressure and water molecules in the air condensation will occur. The water molecules would then runoff into bodies of water that increased in size until it reached the ocean again.

6.) Starting at the largest river; the Amazon in Brazil and Peru; the Orinoco in Venezuela and Columbia; the Congo in the Congo; Yangtze in Tibet, China; and the Bramaputra in Tibet, India and Bangladesh.

7.) Mountains block some rainfall from reaching other places. They cause a rain shadow which creates a dry leeward side of the mountain. This doesn’t really affect my area, there aren’t many mountains.

8.) Three consequences of over-pumping aquifers are subsiding ground levels, sinkholes and saltwater intrusion as well as depletion of water supplies.

9.) 97 percent of water is salt water, 3 percent is freshwater.

10.)An aquifer is a porous layer of gravel, stone or sand that is below the water table. Water enters these aquifers by a seeping process and it stays there.

Chapter 16 notes

slofberg — Thu, 02 Mar 2006 15:09:14 +0000

Air Pollution- physical or chemical changes brought about by the natural processes or human activities that result in air quality degradation
Primary pollutants are released into the air in a harmful form. Secondary pollutants are created or converted into hazardous form after they enter the atmosphere, usually by photochemical reactions.
Clean Air Act of 1970 established seven “criteria pollutants(sulfur dioxide, carbon monoxide, particulates, volatile hydrocarbons, nitrogen oxides, photochemical oxidants, and lead)- greatest threats to human health; over 660 other pollutants have been added to this list.
More than 200 million Americans live in an area where the risk of death from air pollution effects is greater than the acceptable level of 1 in 1 million. Indoor air is a major part of this health risk, with pollution levels often greater than those outdoors.
Globally, some 2.5 billion people (mostly women and children) are exposed to hazardous levels of smoke from poorly ventilated heating and cooking fires. All together, air pollution constitutes for more deaths per year than any infectious disease.
Aerosols and air toxins can be carried long distances by wind currents. Dust from Chinese deserts, for example, often falls out of the American West. Through a process of sequential evaporation and precipitation, hazardous air pollutants are accumulating in tha Arctic and Antarctic, where they concentrate through food chains to reach dangerous levels in both humans and top predators like polar bears and whales.
Chloroflurocarbons(CFC’s) and other long lasting chlorine containing compounds migrate into the stratosphere where they destroy the ozone layer that protects us from harmful ultraviolet solar radiation. The Montreal Protocol, which called for a phase out of these chemicals, is one of the best examples of international cooperation to fight global air pollution.
Sulfur and nitrogen oxides react in the air to form sulfuric and nitric acids, which fall to earth as acid rain, snow, or dry precipitation. These acids pollute surface waters, kill aquatic organisms, harm vegetation, destroy building materials, and reduce visibility. Pollution controls have greatly reduced these emissions but more needs to be done.
Clean Air Acts passed in most developed countries and in many developing countries are among the central tools for environmental protection. Greatly decreasing global air pollution. Highly controversial facet of this act is the “new source review,” which requires that modern pollution control equipment be installed when old power plants or factories are expanded or upgraded.
Market based approaches to pollution control have been proposed as solid alternatives to government mandates for specific equipment requirements or emission limits. Determining the best way to regulate air quality remains a controversial question.
Air quality has improved dramatically over the past 30 years in most developed countries. Air pollution remains a grave issue however in many poorer countries, especially in the megacities or the developing world and the former Soviet Union.
