Animals Live Nes 5, Here's one simple check of the above numbers. Many broiler chickens in the US are killed at weeks of age. Say it's 6 weeks. So these estimates seem pretty close. The global numbers don't match as well. Over 65 billion land animals were killed for food globally aroundcompared against If the proportions of types of animals globally are the same as in the US, this would imply that 9.
If there were 8. Either this discrepancy is a symptom of bad data, or global proportions don't match US proportions, or chickens outside the US live longer. 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. This seems reasonable in light of Gaston et al. Mammals Matheny and Chanafter discussing Gaston et al. Based on a British study by Gaston and Evans and Harris et al. 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. Yalden's article " A History of British Mammals ". Yalden compares against Britain's adult human population rather than its entire human population "for fairer comparison with just the breeding populations of other mammals".
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. Great Britain has a land area ofkm2. Smil roughly agrees with this number p.
Smil adds regarding this and other abundance estimates pp. However, it's important to point out that the high zoomasses of large herbivores are reported in Africa.ALMOST SIX THOUSAND LINKS TO WEB SCIENCE FICTION RESOURCES!

History and Theory, Theme Issue 50 (December ), This essay argues that concerns about historical distance arose along with modernist historicism, and they disappear with postfoundationalism. David Hume (—) “Hume is our Politics, Hume is our Trade, Hume is our Philosophy, Hume is our Religion.” This statement by nineteenth century philosopher James Hutchison Stirling reflects the unique position in intellectual thought held by Scottish philosopher David Hume.
Part of Hume’s fame and importance owes to his boldly skeptical approach to a range of philosophical subjects.
