Reducing our Carbon Footprints

Yesterday we took a few quizzes where we answered questions regarding how we do things in our lives, such as transportation, shelter, electronics, such and such.  For one of these quizzes there were subtotals to each category, then we had to add all those subtotals, after that divide that number by this other number, and that would be the number of planets needed for the human race, if every human lived just like us.  Of course it was individualized, so these numbers were different for everyone.  For me it was 8.21, for this other kid in the class it was like 3.

We then had to list a few things we could do to perhaps make that number lower.  I considered not using a laundry dryer and instead placing my clothes out in the yard below the sun.

Ice Cores

We did this thing where we examined some sticks of ice.  One was pure ice, another had some specks of dirt in it, the last had a lot of frozen dirt.  We found that they all varied in masses and volumes.

We measured the Ph of each one.  The first was quite low, the second slightly high, the last at the highest; 13.  This shows proof of climate change affecting the Earth.

A Jump that is lacking in Sound

Check it.  There was this book in 1964 called Silent Spring.  The writer, Rachel Carson, was concerned about the traces of chemicals in stuff.  This thing call DDT was being used as pesticides, but it was doing more than killing the bugs.  So, Rachel Carson went on for over 300 pages saying a ton of things which basically boil down to, "YO MANE, DDT SUCKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

And then in the 70's everyone was all, "YEAH THIS STUFF SUCKS!!!!!!!! LOOK AT ALL THE ANIMALS THAT GOT CANCER BECAUSE OF IT!!!!!!!!!1!!!!!!!!!!!!!!! WE SHOULD BAN IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
