I think that this graph is actually more illustrative of how much support humans need to maintain themselves (the amount of cattle is astonishing). [[User:Lcarsos|lcarsos]]<span title="I'm an admin. I can help.">_a</span> ([[User talk:Lcarsos|talk]]) 07:58, 5 March 2014 (UTC)

:According to [http://www.psychologytoday.com/blog/canine-corner/201209/how-many-dogs-are-there-in-the-world] there are 525 million dogs, assuming 20 kg as average weight, this should give 10 squares in the diagram. I can't find reliable numbers for cats, but there are more cats than dogs, but they don't weigh as much, so their total weight could be similar to that of the dogs. --[[Special:Contributions/108.162.254.160|108.162.254.160]] 08:42, 5 March 2014 (UTC)

Is it mass or weight? --173.245.53.119 06:38, 5 March 2014 (UTC)

It says weight. Since most land animals live on the... land, there is not much difference. I suppose if a lot of aninimals lived near a prime pole vaulting location it could skew the results. 108.162.246.117 06:40, 5 March 2014 (UTC)
