Yet another reason to not use facebook.
Yes people like you are too stupid to be able to change a setting and your only option is failure. Obviously even the most simple of tasks is well beyond your capability.
Facebook sucks by default, no settings can change that.
Oh, and you are dead wrong on the your methane also, but nice attempt with the 'might'. its almost as if you dont know that normal land with mammals living on it also produce methane, and that lake bottoms are notoriously anaerobic..
You didn't even try to check, did you? Here is one source of many.
Also, decay of plant material under hyrdo reseviors and active aquatic microbial digestion is a source of added methane emmissions. Studies show these emissions may be quite high.
No headlines make these emissions sound "quite high" relative to every other energy source they're in-line with solar and wind. They aren't perfect, but they aren't worse than fossil fuels by a factor of 10.
Actually we don't have the data yet to make those claims. Also, if you just look at electrical generation sources you get a different balance as much fossil fuel burning is for transportation and other.
You know you've been spending too much time on the computer when your friend misdates a check, and you suggest adding a "++" to fix it.
