Card preview (9)
microscopic aquatic organisms in sediments converted by heat and pressure into a mixture of hydrocarbons (animal remains)
Petroleum formation
relatively cheap, easily transported, high-quality energy
Pros of petroleum
reserves will be depleted soon; pollution during drilling, transport and refining; burning makes CO2
Cons of petroleum
peat, lignite, bituminous, anthracite
Steps in coal formation
chlorinated hydrocarbons (DDT); organophosphates (malathion); carbamates (aldicarb)
Major insecticide groups (and examples)
saves lives from insect-transmitted disease, increases food supply, increases profits for farmers
Pesticide pros
genetic resistance, ecosystem imbalance, pesticide treadmill, persistence, bioaccumulation, biological magnification
Pesticide cons
better agricultural practices, genetically resistant plants, natural enemies, biopesticides, sex attractants
Natural pest control
predators, diseases, parasites
In natural ecosystems, methods which control 50-90% of pests
