Learn About Biofuels!

A biofuel is any fuel derived from biological matter.  Here are some examples:

GASOLINE & PETROLEUM
The most commonly used biofuel today - made from biomass that died millions of years ago (think dinosaurs and ancient jungle growth!)  Also, the leading cause of global warming.  Hmmm...  What are some other options?

CORN
Yup, fuel made from corn!  Emissions are lower, but not by much.  Growing all that corn may also require more energy than it actually produces.

SUGAR CANE
A totally sweet fuel!  Fuels made from sugar cane crops can reduce greenhouse gas emissions by up to 56%!  A big success so far in Brazil.

SWITCHGRASS
This amazing plant turned biofuel can reduce greenhouse gas emissions by up to 90%!  Some kinds of switchgrass can also remove CO2 from the atmosphere and store it in the ground.

USED COOKING GREASE
The cooking oil used to deep fry things like french fries and chicken wings can be recycled into fuel!  Fuel made from used cooking grease releases fewer gases and is a great way to REUSE something that would have been thrown away.

KELP
Scientists have recently found that seaweed can be used for fuel as well.  Breaking down the sugars in kelp can create five times as much ethanol as corn.

WHAT IS GLOBAL WARMING?

"Global climate change" or "global warming" began with the Industrial Revolution.  Scientists say that global warming is primarily caused by the "greenhouse gas effect."  Greenhouse gases are the toxins (mostly CO2) released into the air when we burn fossil fuels--oil, coal and natural gas.  Another contributor to global climate change is deforestation (the destruction of trees), illustrated in the photograph below.

During the Industrial Revolution, lots of amazing new technology came along and we've been inventing cool things ever since!  But all this new technology--things like trains, cars, lightbulbs, computers, airplanes and electric toothbrushes--need energy to make them go!  The energy we use to power our cars and our homes comes mostly from burning fossil fuels.  It took millions of years for fossil fuels to be created, but humans have burned much of them up in just a few hundred years and the Earth can't handle it!

The more CO2 we have in the air, the more oceans try to suck it up to balance it out.  The more CO2 the oceans suck up, the warmer they become.  The warmer the oceans become, the more strange weather and wacky temperatures we get!  Strange weather leads to dangerous situations for humans.  Wacky temperature changes leads to the inability of many species of plants and animals to adapt quickly enough, which can lead to extinction.

On land, trees are an amazing natural way to get rid of CO2.  Plants soak up CO2 and store it for energy.  The combination of the greenhouse effect and deforestation has created a problem twice the size!

Obvious solutions:  1) PLANT TREES!  2) STOP BURNING FOSSIL FUELS!
