unit 6: environmental Flashcards
how do humans change the earth
intentionally by modernizing lifestyle, to make life easier
Air pollution
Burning fossil fuels
how does air pollution affects the environment
respiratory problems, bad for wildlife, acid rain
water pollution
lack of waste water management system
examples of water pollution
human waste, factory waist, agricultural waster
land pollution
burying trash in landfills
why are landfills negative
Poor landfill contaminate groundwater, how does materials make areas unlivable
sustainability
living a lifestyle that is not deplete the earth’s resources
how do we move in the direction of a more sustainable lifestyle
Morae fission cars, less reliance on fossil fuels, more renewable energy
crowdsourcing
giving the world a problem for people to solve
Micro approach
small effect by everyone to make a difference, solar panels
institutional approach
Big to replace big, solar farms
dependence on fossil fuels
cool for burning primarily to generate electricity, natural gas burn to generate electricity, petroleum greatest use is for fuel
Metal production
Iron, used to make steel products aluminum, lighter and stronger than steel rare earth minerals, use largely in advanced technological applications
biofuels
made from renewable resources, ethanol and biodiesel
renewable resource
resource which is replaced naturally and can be used again, t
examples of renewable resources
oxygen, freshwater, solar energy, timber, biomass
how if humans use renewable resources unsustainably
modernizing, pollution, frequent changes
nonrenewable resources
A resource of economic value they cannot be readily replaced by natural means
examples of non-renewable resources
fossil fuels oil natural gas and coal
how if humans used non existent renewable resources unsustainably
used too much and damaging the environment
sustainability
The capacity to Indore how biological systems remain diapers and productive in efficiently
examples of sustainable practices
Green building, wind energy, organic food
examples of non-sustainable practices
farming, mass consumption, loss of farming soils, pollution, human population
how to live more sustainably
reduce the use of nonrenewable resources, identify alternatives, reduce stress on renewable resources, reduce population, change consumerist lifestyle
fossil fuels
deposit of organic materials form from Decatur plants and animals that of been converted
uses for fossil fuels
Power, vehicles, heating and cooling, running appliances
why are we become dependent on fossil feels
so much of it, used to it
alternatives to fossil feels
biodiesel, chemically stored electricity, vegetable oilers
causes of air pollution
Burning fossil fuels and construction activity, exhaust
effects of air pollution
aggravate the conditions of individuals, long-term health effects
causes of water pollution
sewage and wastewater
effect of water pollution
human health, health of organisms
causes for land pollution
D4 station, agricultural activities, mining, landfills
affects of wind pollution
climate patterns, human health, wildlife
how can crowdsourcing uses all problems
several people offer best ideas, select the best result
how do humans interact with the earth
adapt to the earth, hunters and gatherers come early agriculture
