I’ve been involved in several on line debates regarding this actually little debated topic. A lot of people on one side of this discussion have professed that the debate is clear that humans have irrevocably harmed the environment and have caused the planet to heat up to our ultimate demise.
I was doing a little thinking on this subject, particularly since the big culprit that environmentalists hang their hat on is the amount of CO2 emitted by cars into the atmosphere as being one of the leading causes. I was thinking about this and wanted to crunch some numbers. The data that I’m using was found on the internet so there could be some pretty big errors due to originating data errors. First, let’s look at cars and some facts that I found:
- The average American drives around 12000 miles per year.
- Let’s assume that 45% of the US population drives (I arrived at this figure by backing into some other figures that were released by a department of the US gov’t under Clinton)
- Let’s assume that 40% of the miles driven in the world are driven by an American (personally I think that’s high)
- The current EU emission goal is 499 grams per kilometer.
All of these figures will calculate out to about 3,270 billion kilos of CO2 emitted by automobiles around the world every year. That’s a lot.
Now, let’s look at what our basic survival emits per year. I found a stat out on the web that the average person exhales about 1.98 pounds of CO2 per day. Now if the world population is now 6.6 billion, that will calculate out to 2,166 billion kilos of CO2 emitted per day — JUST BY BREATHING.
I honestly don’t see what the fuss is all about about what we’re doing to the environment with all of our cars. The worldwide use of automobiles only adds 50% more CO2 into the atmosphere than just breathing does.
Personally, if the environmental crowd is so hepped up on what we as humans are or are not doing to the environment they really need to start off by looking at population control as the first line of defense.
