A typical light bulb wastes what percent of electricity?
a. 5 percent
b. 30 percent
c. 65 percent
d. 90 percent
The answer is d.
The typical incandescent light bulb turns only about 10 percent of its electricity into light. A typical light bulb, when on, is hot. That's because 90 percent of the energy is wasted as heat, which means it isn't very energy-efficient. ENERGY STAR-qualified lighting, such as compact fluorescent bulbs, uses two-thirds less energy and generates 70 percent less heat than an equivalent incandescent light bulb.

Mercury should be carefully cleaned up and disposed of when you
a. visit the innermost planet
b. break a thermometer
c. transmute lead into gold
d. deliver messages quickly
The answer is b.
When liquid mercury (also known as elemental or metallic mercury) is spilled, it forms droplets that can accumulate in the tiniest of spaces and then emit vapors into the air. Mercury vapor in the air is odorless, colorless, and very toxic! Most mercury exposures occur by breathing vapors, by direct skin contact or by eating food or drinking water contaminated with mercury. Any amount spilled or leaked must be treated with extreme caution and cleaned up or removed immediately and very carefully so as not to spread any contamination.

In case of oil or chemical spill, who you gonna call?
a. the neighbors
b. the marines
c. the national response center
d. the garbage collector
The answer is c.
To report an oil or chemical spill, call 1-800-424-8802. An environmental
emergency is a sudden threat to the public health, or the well-being of the
environment, from the release or potential release of oil, radioactive materials,
or hazardous chemicals. Environmental emergencies may happen from transportation
accidents, events at chemical or other facilities using or manufacturing
chemicals, or as a result of natural or man-made disasters. They can be large
spills in the ocean or small spills along a neighborhood street. While there
are many serious environmental problems EPA is concerned with, an emergency
response generally focuses on a sudden, immediate threat.

What's one cause of hypoxia in the environment?
a. Spicy food
b. Greenhouses
c. Nutrient runoff
d. Drought
The answer is c.
Hypoxia means there isn't enough oxygen in the water to support aquatic life. The condition is often caused by excess nutrients that run off into waterways, causing plant and algae blooms that consume oxygen in the water. Hypoxia occurs in the bottom waters of gulfs or sounds where there is less flow to the open ocean. Read more about runoff "nonpoint source" pollution.
If your skin burns in ten minutes, what SPF sunblock should you use if you plan to be outside for 5 hours?
a. SPF 4
b. SPF 15
c. SPF 30
d. Just stay inside
The answer is c.
Sun Protection Factor, or SPF, is a multiple of how much time you can stay
in the sun without burning your skin. If your skin burns in ten minutes,
and you use SPF 30, you should be able to stay in the sun for 300 minutes
(5 hours) without burning (length of time for your skin to redden x SPF =
length of time you're protected. . The higher the SPF value, the greater the
protection. It is recommended that you apply several times a day, especially
if you sweat or are in the water. Sunscreen lotion with SPF prevents the
absorption of UV-B rays from the sun. Overexposure to the sun not only causes
sunburn, but can also cause eye damage premature wrinkling, skin cancer,
and damage to your immune system.

What's the number one trash item found on beaches?
a. cigarette filters
b. plastic bottles
c. seaweed
d. food bags
The answer is a.
From 1996 to 2000, international marine debris collectors found over 6 million cigarette filters on beaches, followed by over 3 million food bags. Where do all the cigarette filters come from? Much of the blame must be placed on careless beachgoers, but they are not the only source. Smokers who flick cigarette filters out of a car window, stamp cigarettes out on a sidewalk, or dump out their car ashtrays in a parking lot contribute to the marine debris problem. Cigarette filters can wash or blow down storm drains that lead into our local waterways and eventually, the ocean.

How can a plastic bucket help protect the environment?
a. warning bell
b. recycling tote
c. scientific anchor
d. diaper pre-soak
The answer is c.
Conventional anchors that are used to hold scientific instruments on the sea bottom can sometimes disrupt or damage surrounding sea life. A new type of scientific anchor, using only a plastic bucket filled with sand, was invented that hold instruments securely in place, but also minimizes impacts to the environment. A lid on the bottom of the bucket keeps the sand inside while the anchor is being lowered to the seafloor. However, when the anchor is lifted up, the lid flops open, releasing the sand onto the seafloor. Detailed information about the new anchor from the National Oceanic and Atmospheric Administration.

Cruise ships generate a large volume of waste due to
a. exotic destinations
b. spicy food served
c. numbers of passengers
d. multiple time zones
The answer is c.
Large cruise ships provide overnight accommodations for 3,000 or more passengers for multiple days. In contrast to similarly-sized cargo ships, cruise ships generate a substantially larger volume of wastewater due to the higher number of passengers and crew. In addition, cruise ship passengers have access to special services such as fine dining, dry-cleaning, photo processing, salons and spas, medical services, and others, all of which can add to waste streams not usually present on other vessels.
Vessels are responsible for proper trash disposal. It is illegal to dump plastic refuse, and garbage mixed with plastic, into any waters; and dumping non-plastic trash and other forms of garbage is restricted. The law applies to all U.S. vessels wherever they operate (except in waters under exclusive jurisdiction of a U.S. state) and to foreign vessels operating in U.S. waters. With 3,000 or more passengers, cruise ships have potential to cause a large environmental impact if they do not dispose of waste properly. Report suspected illegal dumping to the National Response Center at 1-800-424-8802 or the Coast Guard at 1-800-368-5647.

How can scrap tires help save the environment?
a. better education
b. make lots of swings
c. drive fewer miles
d. burn them for fuel
The answer is d.
In 2003, 130 million scrap tires were used as fuel, up from 25.9 million in 1991. Tires can be used as fuel either in shredded form - known as tire derived fuel (TDF) - or whole, depending on the type of combustion device. Scrap tires are typically used as a supplement to traditional fuels such as coal or wood. There are several advantages to using tires as fuel:
- Tires produce the same amount of energy as oil and 25% more energy than coal
- The ash residues from TDF may contain a lower heavy metals content than some coals.
- Results in lower NOx emissions when compared to many U.S. coals, particularly the high-sulfur coals.

What's one way you can fight mosquitos?
a. Use tiny swords and shields
b. Install a protective force-field
c. Empty standing pools of water
d. Move to a cold climate
The correct answer is c.
While moving to a cold climate is a possibility, it's an extreme one at best. However, a serious consequence of some mosquito bites may be transmission of certain serious diseases such as malaria, West Nile fever, and several forms of encephalitis. Not only can mosquitoes carry human diseases, they also can carry several diseases and parasites of dogs and horses. Fortunately, there are many things you can do to reduce risks from mosquitos, for example:
-
Empty standing water in old tires, cemetery urns, buckets, plastic covers, toys, or any other container where "wrigglers" and "tumblers" live.
-
Empty and change the water in bird baths, fountains, wading pools, rain barrels, and potted plant trays at least once a week if not more often.
-
Drain or fill temporary pools with dirt. Keep swimming pools treated and circulating and rain gutters unclogged.
-
Use mosquito repellents when necessary and follow label directions and precautions closely.

A "red tide" or "harmful algal bloom" is natural event
caused by rapid growth of microscopic, single-celled algae that makes the
ocean looks red or brown, especially in summertime, and especially when rains
wash more nutrients into rivers and the sea. Most kinds of algae are harmless
plants but some types produce a natural toxin that can contaminate shellfish
that eat the algae. Animals or humans who eat the contaminated shellfish
can be poisoned. Local fishing areas are usually closed during major red
tides to prevent harvest and sales of contaminated shellfish. Local fish
advisories tell you when to avoid buying or eating shellfish.

What's the number one trash item found on beaches?
a. cigarette filters
b. plastic bottles
c. seaweed
d. food bags
The answer is a.
From 1996 to 2000, international marine debris collectors found over 6 million
cigarette filters on beaches, followed by over 3 million food bags. Where
do all the cigarette filters come from? Much of the blame must be placed
on careless beachgoers, but they are not the only source. Smokers who flick
cigarette filters out of a car window, stamp cigarettes out on a sidewalk,
or dump out their car ashtrays in a parking lot contribute to the marine
debris problem. Cigarette filters can wash or blow down storm drains that
lead into our local waterways and eventually, the ocean.

What percent of U.S. morning traffic consists of students being driven to school?
a. 5
b. 10
c. 20
d. 35
The answer is c.
Based on national studies, 20 percent of weekday morning traffic in the
US is students being driven to school. These trips can cause increased traffic
congestion around schools, which can prompt even more parents to drive their
kids to school. In addition, short motor trips contribute significant amounts
of air pollution because they typically occur while an engine's pollution
control system is cold and less effective. Safe walking routes for school
kids help alleviate traffic congestion and related pollution.

How can a plastic bucket help protect the environment?
a. warning bell
b. recycling tote
c. scientific anchor
d. diaper pre-soak
The answer is c.
Conventional anchors that are used to hold scientific instruments on the sea bottom can sometimes disrupt or damage surrounding sea life. A new type of scientific anchor, using only a plastic bucket filled with sand, was invented that hold instruments securely in place, but also minimizes impacts to the environment. A lid on the bottom of the bucket keeps the sand inside while the anchor is being lowered to the seafloor. However, when the anchor is lifted up, the lid flops open, releasing the sand onto the seafloor. Detailed information about the new anchor from the National Oceanic and Atmospheric Administration.
Mercury should be carefully cleaned up and disposed of when you
a. visit the innermost planet
b. break a thermometer
c. transmute lead into gold
d. deliver messages quickly
The answer is b.
When liquid mercury (also known as elemental or metallic mercury) is spilled, it forms droplets that can accumulate in the tiniest of spaces and then emit vapors into the air. Mercury vapor in the air is odorless, colorless, and very toxic! Most mercury exposures occur by breathing vapors, by direct skin contact or by eating food or drinking water contaminated with mercury. Any amount spilled or leaked must be treated with extreme caution and cleaned up or removed immediately and very carefully so as not to spread any contamination.

How did old subway cars land in the Atlantic Ocean?
a. The "F" line didn't end at Coney Island
b. Creating calamity movie scenes
c. Put there to create artificial reefs
d. Sea salt is a natural exfoliant
The answer is c.
Reefs provide a home for fish and other ocean wildlife. When an artificial reef is placed on the ocean floor, sea life such as sponges and coral begin to cover the material. Then small fish and animals take up residence, attracting larger animals. Many different types of materials can be artificial reefs, such as the bodies of vehicles, old ships, or large pieces of construction rubble. In August 2001, New York City subway cars were slid off a barge into the Atlantic Ocean 10 miles east of Rehoboth Beach, Delaware, to become an artificial reef.

Water-efficient fixtures can save about how much water per home annually?
a. 1,500 gallons
b. 9,300 gallons
c. 54,000 gallons
d. 99,000 gallons
The answer is c.
Residential demands account for about three-fourths of the total urban water demand. Indoor use accounts for roughly 60 percent of all residential use. Low-flow plumbing fixtures and retrofit programs are permanent, one-time conservation measures that add little or no additional cost over their life. The City of Corpus Christi, for example, has estimated that an average three-member household can reduce its water use by 54,000 gallons annually and can lower water bills by about $60 per year if water-efficient plumbing fixtures are used.

Household waste in the U.S. generally increases by how much over the holidays?
a. 50 thousand tons
b. 100 thousand tons
c. 1 million tons
d. 10 million tons
The answer is c.
Over the holiday season, consumers flock to malls, department stores and
outlets to search for that perfect gift, that one card that says it all,
that tree to end all trees. But as we feast, give gifts, decorate and travel,
we also consume lots of resources and generate lots of waste. A recent report
noted that the amount of household garbage in the United States generally
increases by 25 percent between Thanksgiving and New Year's Day, from 4 million
tons to 5 million tons.

About how much can you save each year by installing a programmable thermostat?
a. $15
b. $40
c. $75
d. $100
The answer is d.
One great way to save energy and money in winter is to install a programmable thermostat. When installed and used with the four pre-programmed temperature settings for weekend and weekdays, you can save about $100 each year while staying comfortable. Before leaving for vacation, turn down your thermostat (to "hold" a lower setting) so that you don't waste money and fuel by fully heating an empty house. Due to the potential fuel savings, your programmable thermostat will likely pay for itself in its first year.
More tips for weathering the winter
A common misconception associated with thermostats is that a furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings. This misconception has been dispelled by years of research and numerous studies. The fuel required to reheat a building to a comfortable temperature is roughly equal to the fuel saved as the building drops to the lower temperature. You save fuel between the time that the temperature stabilizes at the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

EPA was originally created by which US president?
a. John F. Kennedy
b. Lyndon Johnson
c. Richard Nixon
d. Jimmy Carter
The answer is c.
President Nixon created the US EPA on December 2, 1970. In his message to Congress earlier that year about the plan to create EPA, President Nixon wrote, "As concern with the condition of our physical environment has intensified, it has become increasingly clear that we need to know more about the total environment--land, water, and air. It also has become increasingly clear that only by reorganizing our Federal efforts can we develop that knowledge, and effectively ensure the protection, development and enhancement of the total environment itself."

Cruise ships generate a large volume of waste due to
a. exotic destinations
b. spicy food served
c. numbers of passengers
d. multiple time zones
The answer is c.
Large cruise ships provide overnight accommodations for 3,000 or more passengers for multiple days. In contrast to similarly-sized cargo ships, cruise ships generate a substantially larger volume of wastewater due to the higher number of passengers and crew. In addition, cruise ship passengers have access to special services such as fine dining, dry-cleaning, photo processing, salons and spas, medical services, and others, all of which can add to waste streams not usually present on other vessels.
Vessels are responsible for proper trash disposal. It is illegal to dump plastic refuse, and garbage mixed with plastic, into any waters; and dumping non-plastic trash and other forms of garbage is restricted. The law applies to all U.S. vessels wherever they operate (except in waters under exclusive jurisdiction of a U.S. state) and to foreign vessels operating in U.S. waters. With 3,000 or more passengers, cruise ships have potential to cause a large environmental impact if they do not dispose of waste properly. Report suspected illegal dumping to the National Response Center at 1-800-424-8802 or the Coast Guard at 1-800-368-5647.

What is the most environmentally friendly way to get rid of garbage?
a. recycling
b. composting
c. use less stuff
d. landfilling
The answer is c.
Source reduction is a basic solution to the garbage glut: using less material means less waste at the end. Because source reduction actually prevents the generation of waste in the first place, it comes before other options that deal with trash after it already exists. Recycling (or re-using) and composting are the next best options because they reduce the amount of waste going to landfills and also let materials be re-claimed and used again when possible. Landfilling is the last option, when waste and materials are simply discarded.
For businesses, there are many ways to reduce waste in specific materials or industry sectors. Businesses can save energy and resources, prevent pollution, and find financial incentives for waste reduction. States can get technical assistance, small business assistance, and other similar forms of support for local organizations. RecycleMania is a competition among colleges and universities to see which schools can collect the most recyclables over a 10-week period, with 49 institutions participating in 2005.

How can scrap tires help save the environment?
a. better education
b. make lots of swings
c. drive fewer miles
d. burn them for fuel
The answer is d.
In 2003, 130 million scrap tires were used as fuel, up from 25.9 million in 1991. Tires can be used as fuel either in shredded form - known as tire derived fuel (TDF) - or whole, depending on the type of combustion device. Scrap tires are typically used as a supplement to traditional fuels such as coal or wood. There are several advantages to using tires as fuel:
- Tires produce the same amount of energy as oil and 25% more energy than coal
- The ash residues from TDF may contain a lower heavy metals content than some coals.
- Results in lower NOx emissions when compared to many U.S. coals, particularly the high-sulfur coals.

Why did they electrify a waterway near the Great Lakes?
a. monitor ship traffic
b. prevent harbor freezing
c. block invasive species
d. stop vegetation growth
The answer is c.
An "invasive species" is a plant or animal that is non-native
(or alien) to an ecosystem, and whose introduction is likely to cause economic,
human health, or environmental damage in that ecosystem. Once established,
it is extremely difficult to control their spread. An electrical fish barrier
was used as a demonstration project in the Chicago Sanitary and Ship Canal
to study the effectiveness of preventing species migration between the River
and the Lake. The electrodes pulse DC current into the water, causing fish
will turn back rather than pass through the electric current. The electric
current poses no threat to people.

What's the leading cause of water quality problems in the U.S. today?
a. factories
b. nonpoint sources
c. water treatment
d. toxic waste sites
The answer is b.
Nonpoint source (NPS) pollution is caused by rainfall or snowmelt "runoff" moving
over and through the ground. As the runoff moves, it picks up and carries
away natural and human-made pollutants, finally depositing them into lakes,
rivers, wetlands, coastal waters, and even our underground sources of drinking
water. States report that nonpoint source pollution is the leading remaining
cause of water quality problems.

If your skin burns in ten minutes, what SPF sunblock should you use if you
plan to be outside for 5 hours?
a. SPF 4
b. SPF 15
c. SPF 30
d. Just stay inside
The answer is c.
Sun Protection Factor, or SPF, is a multiple of how much time you can stay
in the sun without burning your skin. If your skin burns in ten minutes,
and you use SPF 30, you should be able to stay in the sun for 300 minutes
(5 hours) without burning (length of time for your skin to redden x SPF =
length of time you're protected. . The higher the SPF value, the greater the
protection. It is recommended that you apply several times a day, especially
if you sweat or are in the water. Sunscreen lotion with SPF prevents the
absorption of UV-B rays from the sun. Overexposure to the sun not only causes
sunburn, but can also cause eye damage premature wrinkling, skin cancer,
and damage to your immune system.

The average U.S. home can accumulate how many pounds of hazardous waste in one year?
a. 10 pounds
b. 50 pounds
c. 100 pounds
d. 500 pounds
The answer is c.
The average home can accumulate as much as 100 pounds of household hazardous waste in the basement or garage and in storage closets in one year. When improperly disposed of, household hazardous waste can create a potential risk to people and the environment. Because of the potential risks associated with household hazardous wastes, it is important that people always use, store, and dispose of materials containing hazardous substances safely:
-
Use and store products containing hazardous substances carefully to prevent any accidents at home. Never store hazardous products in food containers. Keep products containing hazardous materials in their original containers and never remove the labels. Corroding containers, however, should be repackaged and clearly labeled. This will prevent accidental ingestion and also can help protect sanitation workers.
-
When leftovers remain, never mix household hazardous waste with other products. Incompatibilities may react, ignite, or explode; contaminated household hazardous waste may become unrecyclable.
-
Follow any instructions for disposal and use provided on the label.
-
Take household hazardous waste to a local collection program, if available.

A "red tide" is
a. toxic pollution runoff
b. paprika oil spills
c. single-cell plants
d. marching lobsters
The answer is c.
A "red tide" or "harmful algal bloom" is natural event caused by rapid growth of microscopic, single-celled algae that makes the ocean looks red or brown, especially in summertime, and especially when rains wash more nutrients into rivers and the sea. Most kinds of algae are harmless plants but some types produce a natural toxin that can contaminate shellfish that eat the algae. Animals or humans who eat the contaminated shellfish can be poisoned. Local fishing areas are usually closed during major red tides to prevent harvest and sales of contaminated shellfish. Local fish advisories tell you when to avoid buying or eating shellfish.
