how much carbon dioxide is released from burning coal for electricity each year in the US

3.504x10^16 lb CO2 / 1yr

name and explain 2 ingredients in diesel fumes

NOx- inflames tissue, respiratory issues caused from fuel combustion Formaldehyde- causes nausea, dizziness and headaches

2 other environmental issues that the exhaust from diesel engines are linked to

acid rain- SOx mixes with the atmosphere to form acid rain smog- NOx mixes with H2O to create a yellowish haze

describe one advantage and one disadvantage to using GMO as crops

advantage- increases crop yield with higher tolerance to extreme weather disadvantage- connections to severe allergic reactions bc genes that certain people are allergic to are inserted into foods which then make those same people allergic to those foods without being aware that they are

give one advantage and one disadvantage that urbanization has compared to rural areas

advantage- provides job/ transportation disadvantage- releases large amounts of air pollution

give one advantage and disadvantage to the method above

advantage- renewable, available anywhere disadvantage- less powerful on cloudy day, not useful at night

describe one human health condition that arises from food or vitamin deficiency

anemia- lack of iron that leads to a blood disorder that cause fatigue and weakness

negative impacts urban sprawl has on the environment

displacement of native animals causing a ripple effect on the environment, surface and groundwater pollution, loss of wetland

one environmental and societal disadvantage to conventional pesticides

environmental- the environment accumulates the chemical residue from the pesticides overtime and then become pollutants contributing to air pollution societal- many cases of pesticide poising have ben reported which can lead to cancer, abortion, birth defects, etc

give an economic disadvantage that cities may face as urban sprawl increases

higher taxes to maintain city expenses such as building

one pro and con of concerning use of aquaculture to produce more food

pro- continuous source of food for people and marine life con- increase population of invasive species that are harmful to native species

2 practices that would be emphasized when creating environmentally sustainable cities

relying on renewable energy sources like solar power or wind power, public forms of transportation that rely on renewable resources for energy

identify 2 factors that have lead to the increase of urban sprawl

rise in population growth and lots of available land for people to move into

explain 2 environmental impacts food production has on the ecosystem

soil pollution- pesticides from farmlands runoff into nearby rivers or seep into the soil from lack of biodiversity- when land is cleared to make space for faming or food industries, they reduce the number of native organisms who were living in that land

identify one type of solar heating method

solar panels- particles of light generate electricity and is fed into a solar inverter converting it into a current of electricity which can be stored or used immediately

explain integrated pest management and one disadvantage

the combination of pest control methods using old farming methods combined with new techniques disadvantage- requires massive education to of different methods that most farmers don't have and is very difficult to understand

connection between meat industry and air pollution

the meat industry is responsible for 515 of global greenhouse gases because the the feed given to the animals produces waste which contains very high levels of methane gas causing air pollution.

what is the connection that makes diesel engines more of a threat to asthma

they contain 100x more particulate matter which is able to slip by our respiratory defenses and remain in our lungs

2 sustainable agricultural practices for food production

using waste instead of fertilizer increasing crop diversity through crop rotation which increases nutrients int he land and also breaks the pest cycle giving them less available food
