If there were 8. Maybe meat chickens in developing countries tend to live for several months before slaughter? Noah Strycker estimates that there are 24 billion domestic chickens worldwide.

Birds Gaston and Blackburnin a paper titled "How many birds are there? The different methods yield surprisingly consistent estimates of a global bird population of between billion and billion individuals" p.

I think these numbers count all birds, not just breeding birds, based on two hints in the paper: The authors write p. We ignore such details and seek order of magnitude estimates only. To some unknown extent fluctuations in different parts of the globe will be out of synchrony, so that fluctuations in the overall total number of individuals will be less than fluctuations in regional totals.


In contrast, Gaston et al. The "typical" estimate for the global breeding-bird population in is Seabirds are ignored, as they contribute little to the overall total number of breeding birds [ Hence, the lower bound of billion from Gaston and Blackburn still seems to me potentially reasonable.

That said, these figures might also be biased a bit high because "Areas chosen for study may well[ Our calculations put the true figure at the lower end of this range. This piece roughly agrees with the bird density for tropical forest specified above, since it says p.

Two dozen birds per hectare is birds per km2. Smil reports p.

Applied to other continents, this is probably a significant underestimate, as Petersp. Multiplying a global bird population estimate of to billion by 2.

A separately calculated estimate is based on Derek W. In other countries, particularly those with less development and more rainforest, I would conjecture that the mammal-to-person ratio is higher. And then we need to add the mammals in the ocean.

Gaston and Blackburn estimate that there are roughly 40 to 60 birds per human worldwide, while "in Britain there are approximately 2 to 3 birds per head of human population" p.Wild animals are neither good or bad, important or useless.

Importance Of Wild Life Saving

Wild animals simply exist because of God or some event in primordial history. Humans took wild animals and made a different group of animals. The first complete sequence of the pig genome provides a genetic comparison of the domesticated pig and its wild cousins and offers clues to how the animal evolved, according to the cover story in the Nov.
