This claim is simply and obviously wrong.
Compared to all sources of energy -
Earth’s total “energy budget” - (it’s conventional to discuss such things in units of energy/time, or power, which I shall from here on), human metabolism is not a significant source of power:
Earth’s total power budget: about 1.74*10^17 W
World population: about 6.5*10^9
Power of a typical (about 2500 kcal/day) person: about 120 W
Power of world population: about 7.8*10^11 W, or 0.0005% of total.
Note that the normal
solar variation is about 0.1% (over an 11 year cycle), or about 20,000 times as great as the total human contribution to the Earth’s power budget.
For this reason, well-informed discussions of the effects of human beings on global temperature focus not on the actual heat produced by human beings, but on the effect of human beings on the heat-retaining characteristics of the atmosphere.
Although scientifically invalid, I believe UncleAl’s claim illustrates an important social phenomenon: intense resentment by some members of wealthy societies against people of less wealthy ones. This attitude is, I believe, poorly founded in fact.
As a resource
“the third world” (a 54 year old political term of dubious significance for at least the last 10 year) is of potentially greater value than any mineral resource, because it consists of human beings. At our present level of technology, many essential activities, particularly manufacturing of clothing, and agriculture, can only be efficiently done by human beings. If provided with sufficient trade wealth, large populations can have an invigorating effect on the world economy. The third world also contains large areas of some of the most agriculturally productive land on the planet.
As a result, thoughtful people of many political and philosophical persuasions view the third world not as “parasites”, but as a valuable and under-utilized resource. Efforts to encourage it development is not viewed entirely as charity, but also as sound investment.
