Human activities release ______ tons of CO2 per year.3737,00037,000,00037,000,000,00037,000,000,000Human activities release 37 billion tons of CO2 per year. This is in the form of vehicle emissions, factories, and deforestationhttps://www.nrdc.org/stories/how-you-can-stop-global-warming

True or false: Carbon in the atmosphere makes oceans acidic.TRUEFALSETRUEWhen carbon dioxide dissolves in this ocean, carbonic acid is formed. This leads to higher acidity, mainly near the surface, which has been proven to inhibit shell growth in marine animals and is suspected as a cause of reproductive disorders in some fish.

What percent of food ends up uneaten in a landfill?
10%20%30%40%40%Around 10 percent of U.S. energy is used to produce food. Unfortunately 40% of food is wasted. You can help by not buying or taking more than you need, and composting your leftovers.^

What fact about global warming is not true?A Japanese study showed that producing a kilogram of beef leads to the emission of greenhouse gases with a global warming potential equivalent to 36.4 kilograms of carbon dioxide (CO2).Methane, a greenhouse gas like carbon dioxide (CO2), negatively impacts the environment 23 times more than CO2.Emissions like carbon dioxide, nitrous oxide and other greenhouses gases will remain in the atmosphere for about a year.A kilogram of beef is responsible for the equivalent of the amount of CO2 emitted by the average European car every 250 kilometres, and burns enough energy to light a 100-watt bulb for nearly 20 days.Emissions like carbon dioxide, nitrous oxide and other greenhouses gases will remain in the atmosphere for about a year.Emissions like carbon dioxide, nitrous oxide and other greenhouses gases will remain in the atmosphere for many years making impossible to eliminate global warming for several decades.https://www.nrdc.org/stories/global-warming-101

There has been a “pause” or a “slowdown” in rising global temperatures.TRUEFALSEFALSEOver the past 50 years, the average global temperature has increased at the fastest rate in recorded history
8
everyoneWhat fact about global warming is not true?It's caused by CO2 and other greenhouse gases that absorb sunlight and solar radiation. This traps heat on earth.Global temperatures always fluctuate, so the current global rise isn't actually a problemEach year of the 21st century ranks amongst 14 hottest years since 1880Global warming can lead to huge food and water shortages and has a life threatening impact on the wildlife.BYou can reduce your carbon footprint, the total amount of greenhouse gases produced to directly and indirectly support your activities, by reducing your meat consumption.

iceThe production of which food releases the most carbon dioxide?FruitsMeatGrainsVegetablesMeatLivestock farming produces 20-50% of all human-made greenhouse gases. If everyone eats less meat, we can reduce our bad emissions by a quarter!http://www.greeneatz.com/foods-carbon-footprint.html

iceWhat benefits does sea ice have? Choose all that apply.Sea ice reflects 80% of sunlight, keeping the Earth coolerSea ice provides a home for 130+ mammal speciesSea ice regulates polar heat, affecting ocean currents and weather worldwide.Strong sea ice prevents frozen deposits of methane from leaking out and hurting the environment.All of themYou can help save sea ice by raising awareness of how lifestyle changes can make a difference, by taking part in local green initiatives like planting trees, recycling drives, or bike to work days—or starting your own.https://nsidc.org/cryosphere/quickfacts/seaice.html

iceIt's estimated that all the Arctic ice will melt by which year?20402060208021002040The Arctic is one of the places affected the most by global warming. Temperatures there have risen 2x as fast as the rest of the world.http://www.conserve-energy-future.com/various-global-warming-facts.php

iceHow many pounds of carbon dioxide can a single tree absorb in a year?1030507050You can help the environment by planting trees! Trees absorb carbon dioxide and other pollutants, which saves human lives. In fact, trees save roughly 8 lives in New York City every year. https://www.arborday.org/Trees/treefacts/

The most abundant greehouse gas in Earth's atmosphere is ______carbon dioxidemethanenitrous oxidewater vaporwater vaporDid you know that cows fart methane, which is 23 times worse for the environment than carbon dioxide?
14
How much CO2 (in pounds) is released in the atmosphere each day?.4 billion.8 billion1.4 billion1.8 billion1.4 billionCarbon dioxide is just one of many gases that spread around the planet like a blanket, capturing the solar heat that would otherwise be radiated out into space, futhering global warming.
15
What is false about Ozone? An ozone molecule is made of 3 chemically bonded oxygen atoms.It's a pale blue gas with a pungent smell. It reflects ultraviolet radiation from the sun.it absorbs ultraviolet radiation from the sun, thereby protecting living organisms below from this dangerous radiation.It reflects ultraviolet radiation from the sun.There is a growing ozone hole where the ozone layer is weak, allowing solar radiation to reach the Earth's surface and harm people, plants, and animals.

Name 3 of the easiest ways you can change the way you eat to fight global warming.Possible answers: Buying and cooking only what you'll eat and not wasting food, eating foods that are minimally processed and packaged (e.g., potatoes vs. potato chips), purchasing food grown locally, avoiding products that result from tropical deforestation, consuming less meat by eating at least three meatless meals per week.By buying food grown locally, you prevent the economic and environmental costs of transporting the food to you!
17
Name 3 of most common ways yo ucan change the way you travel in order to fight global warming.Possible answers: walking or riding a bike if your destination is close enough or you have the time, using public transportation intead of private cars, using an electric car or other fuel-efficient vehicle.Burning one gallon of gas creates 20 pounds of carbon dioxide. Some people reliably get 58 miles per gallon in their hybrids, while others who drive less carefully are lucky to get eight miles per gallon.
18
Name 3 of the most common ways you can fight global warming by changing the way you buy things.Possible answers: Only buy what you need, reuse what you can, and recycle, avoid products with extra packaging, buy products made closer to home (reduce shipping costs)

What is the average person's carbon footprint?5 metric tons10 metric tons20 metric tons50 metric tons20 metric tonsOf all the greenhouse gases in the atmosphere, carbon dioxide accounts for up to 26 percent of them,[1] which is why people are concerned with reducing their carbon footprint.
20
Which of the following are ways humans produce carbon dioxide?cement productiondeforestation
burning of fossil fuels
all of the aboveall of the aboveCarbon emissions from cement production is so high is because cement has to be heated to very high temperatures, which consumes a large amount of fossil fuels. Furthermore, laying cement is a slow and energy consuming process.
21
Which of the following are natural ways carbon dioxide is produced?decompositionocean releaserespirationall of the aboveall of the aboveWhen organisms die and their body decompose, carbon is released back into the environment. As the world’s oceans warm, their massive stores of dissolved carbon dioxide may be quick to bubble back out into the atmosphere and amplify the greenhouse effect. Respiration is the process of creating energy by taking in oxygen and producing carbon dioxide.
