Climate Change: The human ecology of climate change
No TL;DR found
Abstract
Given that climate change has been part of, and has helped shape, the biosphere's development, it should not have been surprising that climate change affected human evolution and humanity's historical affairs (see Chapter 5), or that it will do so in the future. That humanity itself has affected the climate – modern technological civilisation significantly so – all the more demonstrates the interconnections between climate and our species. If we are to begin to assess this relationship's future it is necessary to understand the relevant fundamentals of human ecology (the way our species as a population develops and its relations with other species). This includes population demographics (broadly our numbers reflect the amount of biomass of, and hence impact on, the species to which we relate), energy supply (which relates to carbon-cycle short-circuiting), health (mainly with regard to those species that prey on us) and food supply (those species which we harvest). Finally, given all of this, what are the prospects for limiting, or ameliorating, our short-circuiting of the biosphere's carbon cycle? Population (past, present and future) and its environmental impact Population and environmental impact Generally, if one person has an environmental impact of some arbitrary quantification, x , then it is not unreasonable to suppose that two people will have an impact of 2 x , three people an impact of 3 x , etc; in other words, that environmental impact is proportional to population and so may be represented in equation form.
