World GDP is $70 Trillion per year and world food business is $5 trillion per year. Not possible.
Majority of world transportation and fuel involves food distribution every day.
Either world food is expensive or world people eat more food.
1 lobster costs some $1000 in a expensive hotel (not sure). Tuna fish are expensive and so on....

Bull elephants weigh 8 tons standing 12 feet tall and they eat 300 kg per day which is 3% of body weight. People also eat close to 2% - 3% of body weight per day.
I bet there are tons of other species that as a whole eat far more than humans do.
For example, there are 163,876,428,562 earthworms (source) in the world. Earthworms eat 1/3 of their body weight in a day. So they consume about 0.13 oz a day, for a total of 485 WTCs per year.
