Pest control Earth
Pest Control/ earth
Integrated Pest Managment Chemical
Converrtial pesticides will remain in use,but they must be screend carefully to aviod harmful ones.
amounts & at a time when they are most effective to minimize their envio. impact
requires monitoring crops and infedtations.
Advantages and Disadvantages of pesticided use
1. portect crops 2.save billions of $
1.cause illness/death 2.crop demage 3. water pollution in rural communitites 4. cleanup costly.
Integratedo Pest Managment cutural control
Controlled by many techniques that dont require chem.
: weeds, noise makers to frigten birds and manual removal of insects from crops.
Mechanism of Earth crustal plate movement
: Alantic ocean is getting bigger bc tectonic movement.
4. Sea floor:
ocean crust movement
Integrated pest managment environment
Pest control gaining pop.
reduce or eliminate pesticide use
Alter biotic/abiotic conditions in crops making them inhospitable to pest.
Integrated Genetic control
1.Sterile male technique
: intro o sterile males of pest into the enviro. w/ certain chem.
Prevents union of fertilization
2.plants are resistant to pest and diesase can b developed through genetic engineering and artificial selestion.
Brownish orange shroud of air pollution
Complex mixture of photochemical oxidants and nitrogen oxides
Chemical pollutnat from natural or anthro pogenic source that undergoes chemical change as a result of reacting w/ another pollutant, sunlight atomosphere moisture or other enviormental agents.
Air pollution from natural and anthropogenic sources
Primary pollutants often react w/one another or w/ water vapor.
Anthropogenic pollution and biogenic
1.Pullutants from human sources
create long-term threat bioshere.
: autos, power plants
: produce by living organisms or biological process
: Volcanos, dust strom, forest fires
Brown- air cites
located in warm, dry, and sunny climates and are generally new cities w/few polluting industries.
Source pollution comes from automobiles and electrice power
Major pollutantion> carbon monoxide, hydrocarbons,& nitro oxides.
: LA, Denver
Organic molecules containing hydrogen and carbon released during incomplete combustion of organic fuels.
React with nitrogen and sunlight.
located in cold, moist climates
Major pollutants are surfur oxides and particulates from factories
pollutants combine with atmospheric moisture to from grayish haze called smog.
Air pollutant cause shortness of breath to eye irritation to death to headaches
Persistent inflammation of bronchial tubes which carry air into lungs.
Includes coughing, mucus buildup,difficult breathing
: Emphysema> lung disease
Permit issued by gov't that allows companies to relase certain amount of pollution.
Companies reduce pollutions by selling permits to other companies.
1. remove harmful substance from emission gases.
2. convert them into harmless substance.
Its a sustainable strategy and its acts like a 1st aid.
Air pollutants arise from vaporization or evaporation attrition (friction)& combustion with is the major producer.
Fossil fuels consist primarily of carbon&hydrogen atoms linked by chem. bonds.
heat released brakes other bonds permitting combustion.
incomplete combustion produce carbon dioxide, monxide and unburned, hydrocarb.
