=Energy Conservatio **n** = ENERGY: Is the ability to do work. Electricity, fuel and water is energy used in our every day lives. Some examples of how energy is used today are...
 * heat building
 * produce goods
 * process foods
 * transportation



ENERGY CONSERVATION: The effort made to reduce energy consumption. A few examples of how to conserve energy are...
 * Turning off lights when not in use
 * Not leaving water running when not in use
 * Not leaving plugs in outlets when not in use
 * Not over heating or over cooling rooms
 * Using fluorescent light bulbs. (they use 1/4 the energy of an ordinary incandescent bulb and last 8-12 times longer)
 * Walking, biking, car pooling or using mass transit instead of driving (every gallon of gasoline saved also saves 22 pounds of carbon dioxide polluting the air)
 * Avoiding using so many disposable batteries. (they contain harmful substances such as lead, arsenic, zinc, cadmium, copper, and mercury.)

=Energy= ENERGY PRODUCTION: There are several different energies that can be produced such as wind energy, solar energy, and fuel as energy



WAYS TO PRODUCE ENERGY:
 * Burning coal, petroleum and natural gases (fossil fuels)
 * Using wind turbines ("Wind Power")
 * Solar panels that absorb the suns rays

=Biotechnology= The science that is applied to the production of biological products or processes
 * It can alter the DNA in living organisms
 * In future scientists expect to use gene therapy to cure some diseases.
 * ex. When genes from humans are inserted into bacteria, the bacteria act as factories, generating chemicals that are important to people.

=Agriculture: Productivity= To track productivity is to measure the amount of edible food that has grown in a given unit of land
 * Chemists test soil to see if it contains the right chemicals to grow a particular crop
 * They use biochemistry to develop plants more likely to survive a drought or insect attack
 * Chemists help to conserve water
 * Finding a reliable way to determine when a crop needs water
 * ex. If the gene that causes a jellyfish to glow is inserted into the potato plant, the potato plant grows when it needs water



// **Agricultural chemistry** // focuses on chemical compositions and changes involved in the production, protection, and use of crops and livestock.

**Agricultural chemists** work with food producers to increase yields, improve quality, and reduce costs. They also study the causes and effects of bio-chemical reactions related to plant and animal growth, seek ways to control these reactions, and develop chemical products that provide help in controlling these reactions.

 * Agricultural productivity is measured as the ratio of agricultural outputs to inputs.
 * Total factor productivity (TFP) is a method of calculating agricultural productivity compares an index of agricultural to an outputs. For example, a year with unusually good weather will tend to have higher output, because bad weather hinders agricultural output.
 * The productivity of agriculture is very important. Aside from providing more food, increasing the productivity of farms affects the region's prospects for growth and competitiveness on the agricultural market, income distribution and savings, and labor migration.

=Agriculture: Crop Protection=

Crop protection chemicals help farmers manage crop "pests," including weeds, insects and fungi that threaten crop. Crop protection plays important role. Used properly, crop protection chemicals help growers provide a safe, nutritious bounty of affordable foods. Applying crop protection can effectively to increase productivity and save input costs.

Agricultural chemist - The job of an Agricultural chemists is to develop "potions" to protect crops, Such as Pyrethroids.


 * Pyrethroids' chemical structure are very similar to the natural pyrethrins of chrysanthemum flowers. Pyrethrins broken down by sunlight rapidly. They can only last for one to two days. Base on experiment, pyrethroids is more effective, it can last for a few months before they are degraded.

=Identify Pollutants=

Pollutant is a material found in air, water, or in soil that is harmful to humans or other organisms.

T hree factors that determine the severity of a pollutant
 * its chemical nature
 * its concentration
 * its persistence.

Three types of pollutants:
 * Stock pollutants
 * Fund pollutants
 * Notable pollutants

Pollutants can also be defined by their zones of influence, both horizontally and vertically.

=Prevent Pollutant= Each year American produce over 285 pounds of waste. Over 80% of the land field can be recycle, but they are not. A study estimated that litter-ers are responsible for over 2800 asthma attacks, 550 emergency room visits and 41 early death EVERY YEAR.
