Human Impact on the Carbon Cycle
“The red arrow, representing rapid fossil fuel burning, indicates the main way in which
humans affect the natural carbon cycle. Carbon dioxide (CO2) levels are increasing because
the natural system cannot keep pace with this new emission source. The natural processes
that permanently remove this additional carbon - ocean uptake and sedimentation - work
extremely slowly.”

Major Human-Produced
Greenhouse Gases
“Many natural and human-made gases contribute to the greenhouse effect that warms the
Earth's surface. Water vapor (H2O) is the most important, followed by: Carbon Dioxide
(CO2), Methane (CH4), and Chlorofluorocarbons (CFCs).
This diagram shows the relative importance of the major human-produced greenhouse
gases to current warming. CO2 is the most important followed in descending order by CH4,
CFCs, Ozone (O3), and Nitrous Oxide (N2O).”

Human Activity and
Greenhouse Gases-1997 Data
“The world’s economy runs on carbon: the
“fuel” in fossil fuels. Coal, oil, and natural
gas contribute energy to nearly every
human endeavor in industrialized nations,
and carbon dioxide (CO2) is a by-product
of burning these fuels.
This graph containing data for the U.S.
illustrates how thoroughly fossil fuels and
CO2 emissions are integrated into
American life.
CO2 contributes more to the recent
increase in greenhouse warming than any
other gas. CO2 persists in the atmosphere
longer and longer as concentrations
continue to rise.”

Reducing Other Greenhouse Gases
“Methane is the second most significant cause
of greenhouse warming, behind carbon dioxide.
Cows are one of the world's greatest methane
emitters because they exhale methane, a
byproduct of the digestion of their grassy diet.
The sheer size of cow herds makes a significant
contribution to global warming.”

What You Can Do to Reduce
Your Footprint
•
Whether you are at home, buying food, on the road or at work, the energy you
use in your daily life has an impact on climate change.

Take Action - At the Office
•
Recycle glass, paper, aluminum and plastics.
•
Buy recycled paper products and supplies.
•
Telecommute if possible.
•
Turn down the air conditioning.
•
Shutting off your computer at closing time will reduce its carbon
dioxide emissions by 83%.
•
Install a programmable light timer that reduces light usage
during off-peak hours.
•
Install a programmable thermostat

Take Action - Inside the Home
•
Get a home energy audit to find out if your home is poorly
insulated or energy efficient. Many utility companies offer this
service for free. Go to www.energystar.gov for more information
or contact your local utility company.
•
Replace a regular incandescent light bulb with a compact
fluorescent bulb (CFL). Check for possible rebates from your utility
company.
•
Move your thermostat down 2° in the winter and up 2° in the
summer.
•
Clean or replace filters on your furnace and air conditioner.
•
Install window shading.
•
Install a programmable thermostat.

Take Action - Inside the Home
•
Look for the Energy Star® label when choosing appliances.
•
Use less hot water, by installing a low flow showerhead and
washing your clothes in cold or warm water, instead of hot water.
•
Turn off and unplug appliances not in use. Avoid using your
appliances during peak hours, from 4pm to 6pm.
•
Turn down the thermostat on the water heater and wrap your older
model with a water heater blanket.
•
Switch to Green Power.

Take Action - In the Kitchen
•
Support your local farmer. Buying locally will save fuel and keep money in your
community. To find a farmer's market in your area, visit Local Harvest www.localharvest.org/
•
Mind the tap. Conserve water in the kitchen and around the house and garden.
•
Buy fresh foods instead of frozen. Frozen food uses 10 times more energy to
produce and deliver.
•
Avoid heavily packaged products and cut down on your garbage. Give back
that extra napkin or sugar packet. Carry the gallon of milk by the handle instead
of using a bag.
•
Buy organic foods. Organic soils capture and store carbon dioxide at much
higher levels than soils from conventional farms.
•
BYOB, Bring Your Own Bag, when you visit the grocery store.
•
Clean your refrigerator's coils and give it some breath
American Chemical Society
12
Take Action – On the Road
•
Cut back on driving by walking, biking or taking public transportation.
•
Start a carpool with your coworkers, classmates or friends.
•
Keep your car tuned up and your tires properly inflated. Giving your engine a
tune-up can improve gas mileage by more than 4%. Replacing a clogged air
filter can boost efficiency by 10%. And keeping your tires properly inflated can
improve gas mileage by more than 3%.
•
When purchasing a car, choose a fuel efficient vehicle.
•
Fly less and purchase "Carbon Offsets" to balance out your travel.
•
Travel Green. When going on vacation or on a business trip, take your "green
principles" with you.

Consider a Career in Chemistry
•
In simplest terms, chemistry is the science of matter. Anything that can be touched,
tasted, smelled, seen or felt is made of chemicals.
•
Chemists are the people who transform the everyday materials around us into
amazing things. Some chemists work on cures for cancer while others monitor the
ozone protecting us from the sun. Still others discover new materials to make our homes
warmer in the winter, or new textiles to be used in the latest fashions. The knowledge
gained through the study of chemistry opens many career pathways.”
