Environmental Science

The revolution introduced new tech,crop varities and farming practices to the developing world. Advanced crop yields and prevented starvation.Also created problems through by overuse of water,fossil fuels,pollution from fertilizers and pesticides,worsened erosion,salinix=zation and desertfifcation.

chemicals that kill pest organisms

small fraction of these pests may have genes that enable them to be immune to pesticides.Surviving insects after applications will increase in number.

fewer pesticide applocationsreduced use of fossil fuel, better products, however, some feared the food may be dangerous to eat. Another concern-they dont have to be labeled for the consumers

huge warehous or pens designed to deliver energy rich food to animals living at extremely

allow for greater production of food but they contribute to water and air pollution, animals are injected with steriods to stimulate growth and antibiotics to control disease

help ensure a reliable protein source, reduces overharvesting of fish and declining wild stocks, can be energy efficient. However, can increase disease and virsus outbreaks,may spread disease to native stock

dosent deplete soils faster than they forms, dosent reduce the amount of healthy soil, clean water and genetic diversity essential to long term crop and wildstock production.

crops grown free of synthetic fertilizers or pesticide, not genetically engineered, livestock does not get hormone or antibiotic treatment, animals must have access to the outdoors

natural phenomenon greenhouse gases trap heat and warm the lower atmosphere

atmospheric gases that asorb heat

organisms that have been genetically engineered using a technique called recombinant dna technology

dna that has been patened together from dna of multiple organisms

biological science to create products derived from organisms

causes dirrehea, blindness

cycles natural, cyclical changes in the earths rotation and orbit around the sun

the sun varies in the amount of radaition it emits

absorbs CO2, but slower than were adding to the atmosphere

normal conditions winds puch warm water towards western pacific. contitions winds weaken, warm water flows backwards towards s.america. alters weather patterns worldwide

giant heat pump in the atlantic if shut down, N.America and Europe would be colder.

trap bundles that contain small samples of the antient atmosphere
