       | a strong case that the environmental risk from such modifications
       | is smaller than the risk of alternative paths (spray more
       | chemical pesticides, clear more land, etc.) to achieve the same
       | total yields.
       | 
       | The benefit here is very close to zero, though; one wild-type
       | pothos won't affect indoor air quality in any way known to be
       | significant to human health, and neither will thirty. We've
       | already got escaped transgenic GloFish in Brazilian streams;
       | those haven't caused any significant harm yet, but I'd rather we
       | stopped rolling the dice before something does.

           | 
           | A normal person need about 2000 kcalories per day. That's
           | approximately 500g (1/2 kg) (1 pound) of sugar. Eating only
           | sugar is bad, but most carbohydrates and proteins have a
           | similar kcalories to weight ratio.
           | 
           | If the plant absorbs all the CO2 produced by the person, it
           | must rebuild all that sugar back (and store it as cellulose,
           | or starch or even proteins, but again all have a very similar
           | similar kcalories to weight ratio.) So the plant must grow
           | approximately 500g (1/2 kg) (1 pound) per day.
           | 
           | That is like 15kg (30 pounds) per month, that is a weigh of a
           | small child. Or like 150kg (300 pounds) per year that is the
           | weight of one or two adults. Plant's don't grow so much.
           | (Note that you can reduce the weight to one half is the plant
           | only makes oil instead of as cellulose, or starch or even
           | proteins, but it still too high.)
           | 
           | Edit: Self nitpicking: About the reduction of weigh using
           | oil, I used calories per gram instead of carbon per gram.
           | 
           | Oversimplifiying: In sugar the simplified unit is COH2, that
           | has one carbon per 12+16+2=30 atomic units. In oil, the
           | simplified unit is CH2 that has one carbon every 12+2=14
           | atomic units. So the ratio is aproximately 30/14=2.14 instead
           | of the calories ratio that is 9/4=2.5. Both are very similar,
           | so the end remark is still correct. I'm not sure if it's a
           | coincidence or if I think hard enough about energy per atomic
           | bound it get obvious.
           | 
           | Proteins are harder, because amino acids are more diverse. I
           | left the exact calculation for someone else, but as a rough
           | simplification let's use achain of valine. The building block
           | is C5ONH9 that is a carbon for every (12*5+16+14+9)/5=19.8
           | atomic units, so it's something in between. Anyway, don't
           | expect your plant to make too much proteins. Even soy
           | overdosed with fertilizer has only like a 15% of proteins.

               | that's why the company mutated/fed pothos not snakeplants
               | or peace lily. The most difficult answer is, how to make

             | It is why a small box of baking soda has a pull-off side
