C in the Trees: Junk in the trunks

how many cheese­burg­ers does your tree com­pete with?

Hug a tree and what do you get?  Splin­ters from the bark?  A happy feel­ing?

Maybe.

But if you hug a tree while hold­ing a Tree-Tape, you can get both the happy feel­ing of splin­ters and also a mea­sure­ment of how much car­bon the tree is remov­ing from the atmos­phere!  Bonus!

What is car­bon?  Car­bon is an ele­ment that is present in every liv­ing thing.  Sci­en­tists call Car­bon “C”.  Think of it this way.  Your par­ents named you James, but call you Jim.  Or Gertrude but call you Trudy.  Jim, James, Gertrude, Trudy, Car­bon, C, right?

When C gets changed into a gas state, it becomes car­bon diox­ide.  Car­bon diox­ide is also known as CO2.  Sci­en­tists believe that we humans are putting too much CO2 in the atmos­phere by chang­ing the state of C from things like coal and petro­leum, burn­ing it to pro­duce elec­tric­ity and power cars, planes, and so on, and releas­ing the CO2 into the atmosphere.

So many activ­i­ties cre­ate CO2. Mak­ing cheese­burg­ers. Eat­ing candy bars. They require car­bon to be burnt and released, because so much effort is required to make candy, make a burger.

CO2 and C are nec­es­sary to live. But too much CO2 is a waste. It is trou­ble!
Here is an inter­ac­tive map to see more about CO2 on the planet:

But trees, ah trees!  Trees use pho­to­syn­the­sis to take CO2 out of the atmos­phere.  They pro­duce oxy­gen as their waste gas, which is no waste for us.  But they store C in their trunks.  There it stays until some­thing like a for­est fire burns the tree, and then C is released back into the atmos­phere as CO2.

Impress your friends. Use the tree tape to mea­sure how much CO2 that tree in your back yard bal­ances out the C that is used to make a cheese­burger. Tell them, “I am con­duct­ing a very impor­tant study and need to get data about the junk in the trunks.”
