| Zusammenfassung |
| The direct CO2 released by respiration of humans and domesticated
animals, as well as CO2 derived from the decomposition of their
resulting wastes was calculated in order to ascertain the direct and
indirect metabolic contribution of humanity to CO2 release. Human
respiration was estimated to release 0.6 Gt C year−1 and that of their
associated domestic animals was estimated to release 1.5 Gt C year−1,
to which an indirect release of 1.0 Gt C year−1, derived from
decomposition of the organic waste and garbage produced by humans and their
domestic animals, must be added. These combined direct and indirect
metabolic sources, estimated at 3.1 Gt C year−1, have increased 7 fold
since pre-industrial times and are predicted to continue to rise over the
21st century. |
