Which human activitiy produces more CO2?
B. The exhaled breath from politicians debating the issue.
C. Hyperventilating alarmists
Answer:
That would be C if you are looking at per capita production, since many of C follow in the hypocritical ways of their spiritual leader, Al Gore, and burn more fossil fuels than the average person.
Al Gore has A, B, and C so covered that he skews the curve for all the other alarmists.
A. Without question. The amount of carbon dioxide exhaled by politicians and alarmed people is minute compared to the amount produced by the combustion of fossil fuels.
A. of course
The answer is C, and it's getting worse every day.
Surprisingly it matters most where the CO2 comes from. A. is the cause of global warming, B. and C. are unimportant. Here's the science of why that is true.
There are a great many natural sources and sinks for carbon dioxide. But the present global warming is (mostly) the result of man made CO2 from burning fossil fuels.
There is a "carbon cycle" that recycles natural CO2. But it's a delicate balance and we're messing it up.
Look at this graph.

The little squiggles are nature doing its' thing. CO2 falls a bit during summer when plants are active, and rises during the winter. The huge increase is us, burning fossil fuels. The scientists can actually show that the increased CO2 in the air comes from burning fossil fuels by using "isotopic ratios" to identify that CO2. The natural carbon cycle buried carbon in fossil fuels over a very long time, little bit by little bit. We dig them up and burn them, real fast. That's a problem.
Man is upsetting the balance of nature. We need to fix that.

A.
it is a fact that CO2 is a product of forest fires, rotting vegatation, exhaling animals, etc.
CO2 is used, and oxygen is produced by plants.
that process has been active for millions of years, relatively in balance.
the fact that the levels of atmospheric CO2 have nearly doubled indicates that something has changed.
that something is our use of coal and oil.
the problem is not, which is the greatest source of CO2.
the problem is what is different, and is causing the excess CO2 in the atmosphere.
it is a troll question.
it is also, an honest answer.
I prefer to go with D... smart aleck FunQA.com question submitters.
d. constant farting and burping
Probably farting.hang on. that's B!
My best answer will be A) Burning fossil fuels
B. Because the others can be filtered. And I have yet to find a way to shut a politician up.

Here is one that is causing more havoc on our environment than buring fossil fuels or the rest.
The raising of cattle for beef consumption causes more global warming than all of the cars exhaust on this planet. It starts with thousands of sq. miles of tropical rainforest being cut down and burned to raise much of the cattle. Then the amount of methane gas(a global warming gas) that is expelled by cattle. 100 million tons of methane gas a year is expelled by cattle just in the U.S. alone. The amount of water to raise these cattle is beyond belief also. It takes about 20 acres of land a year to supply the protein a person needs by eating beef and over 2500 gallons of water. For a vegetarian it takes 1 acre of land to supply the protein they need for one year and about 40 gallons of water. Stop eating beef and you will be doing more to stop global warming than many other opitions.
