What is A.) Methane
Methane is a greenhouse gas that is 86 times more powerful than carbon dioxide when it comes to global warming potential.
How does agriculture affect the soil? A.) Increases water retention of soil B.) Improves soil fertility C.) Deprives nutrients from soil
What is C.) Deprives nutrients from soil
Growing crops uses up nutrients from the soil, decreasing its fertility.
How can we decrease the amount of wasted food?. A.) Donate food to food pantries B.) Landfill food C.) Forget about the food
What is A.) Donate food to food pantries
Donating food to food pantries can help people in need to have access to food, which saves food instead of having to send it to a landfill.
How much water is nationally lost due to food waste? A.) 10%-19% B.) 21%-33% C.) 37%-45%
What is B.) 21%-33%
Water is used to produce fruits, vegetables, and meat. Approximately 40% of food produced is wasted.
About how many pounds of pesticides are used for agriculture in the United States? A.) 100 million pounds B.) 200 million pounds C.) 300 million pounds
What is B.) 200 million pounds
Pesticides are used to protect produced food. Since 40% of food is wasted, about 80 million pounds of pesticides is wasted.
What do greenhouse gases cause? A.) Reverse Osmosis B.) Global Warming C.) Nitrogen Fixation
What is B.) Global Warming
Greenhouse gases cause global warming through absorbing and emitting infrared radiation, heating the atmosphere.
How much of produced food is landfilled due to not meeting the aesthetic requirements? A.) 5% B.) 10% C.) 20%
What is C.) 20%
Crops that do not meet the aesthetic requirements are landfilled because they do not have the "perfect" size, shape, or color.
How does deleting unpopular food from the school menu decrease food waste? A.) students will stop eating food from the cafeteria B.) students will bring their own lunches instead C.) students will less likely waste a food that they don't like if it's not offered
What is C.) students will be less likely waste a food that they don't like if it's not offered
Vegetables like bagged carrots are unpopular on campus, so removing them from the menu would cause less students who are forced to get them to throw them away.
How many shower minutes equate to the production of 1lb. of beef A.) 160 shower minutes B.) 225 shower minutes C.) 370 shower minutes?
What is C.) 370 shower minutes?
To yield 1lb. of meat, water is used to produce both feeding and drinking purposes for livestock
What is the national cost of fertilizer used on wasted food? A.) $4.6 million B.) $5.3 million C.) $6.7 million
What is A.) $4.6 million
1/5 of fertilizer is used on wasted food, amounting to $4.6 million.
What does the rotting of wasted food cause? A.) Oxidation B.) Decomposition C.) Photosynthesis
What is B.) Decomposition
Anaerobic bacteria decomposes food, which releases greenhouse gases.
How many acres of cropland is nationally used on wasted food? A.) 10 million acres B.) 20 million acres C.) 30 million acres
What is C.) 30 million acres
The average American consumer wastes about 422 grams per day, amounting to 30 million acres wasted per year.
How can share bins be more encouraged as a way to redistribute food instead of wasting it? A.) Replacing them with refrigerators B.) Removing share bins C.) None of the above
What is A.) Replacing them with refrigerators
Replacing share bins with refrigerators would increase its aesthetic appeal and encourage more students to place their uneaten food there as an alternative.
What percent of water used to produce 1 lb. of chicken is used to 1 apple? A.) 127% B.) 242% C.) 349%
What is B.) 242%
104 shower minutes is used to produce a pound of chicken while 43 shower minutes is used to produce an apple. (104 shower minutes/43 shower minutes)(100)= 242%
What does the use of fertilizers on growing food cause? A.) Photosynthesis B.) Cultural Eutrophication C.) Oxidation
What is B.) Cultural Eutrophication
Fertilizers can run off into local water ways, causing an algal bloom. The algae will eventually decompose, lowering oxygen levels and increasing BOD.
Food waste nationally contributes to how much of the greenhouse gas footprint? A.) 2.6% B.) 7.9% C.) 13.2%
What is A.) 2.6%
Food waste has nationally produced as much emissions as 37 million passenger vehicles.
Why are a lot of crops wasted? A.) Lack of storage space B.) Pests C.) All of the above
What is C.) All of the above
Crops can go bad when they are not stored properly and may be eaten by pests, which lowers its aesthetic appeal, so less are willing to buy the crops.
Why is composting better than landfilling? A.) It's cheaper. B.) It uses less space. C.) All of the above
What is C.) All of the above
Composting is cheaper because it can be processed by student volunteers and uses up less land used for landfilling
What sources of water can be polluted as a result of food waste?: A.) groundwater B.) surface water C.) all of the above
What is C.) all of the above
Runoff containing animal feces and fertilizers can enter surface water or percolate into the ground. Water sources are in vain when food, which pollutes the water throughout its production, is wasted.
The use of pesticides to produce food can cause which of the following? A.) Cultural Eutrophication B.) Pesticide Treadmill C.) Respiration
What is B.) Pesticide Treadmill
Pests that are continuously exposed to chemicals may gradually become immune to them. Pesticides used to protect fruits and vegetables would be used in vain when people waste them.
How does meat production contribute to greenhouse gas emissions? A.) cattle belch B.) pigs snort C.) horses neigh
What is A.) cattle belch
Cattle belch methane, a greenhouse gas that contributes to climate change.
What percent of America's cropland is used to grow uneaten food? A.) 7%-13% B.) 18%-28% C.) 30%-39%
What is B.) 18%-28&
18%-28% of America's cropland is equivalent to the area of New Mexico
How does composting to reduce food waste improve the soil? A.) Adds nutrients to soil B.) Improves water retention of the soil C.) All of the above
What is C.) All of the above
Composting adds both macronutrients and micronutrients to the soil while allowing soil to hold more water, reducing runoff.
