that-weird-breton-girl:Overpopulation DOES indeed harm the environment. When we have more people, food production has no choice but to increase. And people have demands for houses, jobs, wants, etc. The carbon footprint will increase. There are so many other things that will/and are happening. Capitalism as of right now is negatively affecting the environment, but so is overpopulation.Consumption Dwarfs Population as Main Environmental ThreatIt’s overconsumption, not population growth, that is the fundamental problem: By almost any measure, a small portion of the world’s people — those in the affluent, developed world — use up most of the Earth’s resources and produce most of its greenhouse gas emissions.***Take carbon dioxide emissions — a measure of our impact on climate but also a surrogate for fossil fuel consumption. Stephen Pacala, director of the Princeton Environment Institute, calculates that the world’s richest half-billion people — that’s about 7 percent of the global population — are responsible for 50 percent of the world’s carbon dioxide emissions. Meanwhile the poorest 50 percent are responsible for just 7 percent of emissions.Although overconsumption has a profound effect on greenhouse gas emissions, the impacts of our high standard of living extend beyond turning up the temperature of the planet. For a wider perspective of humanity’s effects on the planet’s life support systems, the best available measure is the “ecological footprint,” which estimates the area of land required to provide each of us with food, clothing, and other resources, as well as to soak up our pollution. This analysis has its methodological problems, but its comparisons between nations are firm enough to be useful.They show that sustaining the lifestyle of the average American takes 9.5 hectares, while Australians and Canadians require 7.8 and 7.1 hectares respectively; Britons, 5.3 hectares; Germans, 4.2; and the Japanese, 4.9. The world average is 2.7 hectares. China is still below that figure at 2.1, while India and most of Africa (where the majority of future world population growth will take place) are at or below 1.0.The United States always gets singled out. But for good reason: It is the world’s largest consumer. Americans take the greatest share of most of the world’s major commodities: corn, coffee, copper, lead, zinc, aluminum, rubber, oil seeds, oil, and natural gas. For many others, Americans are the largest per-capita consumers. In “super-size-me” land, Americans gobble up more than 120 kilograms of meat a year per person, compared to just 6 kilos in India, for instance.I do not deny that fast-rising populations can create serious local environmental crises through overgrazing, destructive farming and fishing, and deforestation. My argument here is that viewed at the global scale, it is overconsumption that has been driving humanity’s impacts on the planet’s vital life-support systems during at least the past century. ***Of course, economic activity is not the same as ecological impact. So let’s go back to carbon dioxide emissions. Virtually all of the extra 2 billion or so people expected on this planet in the coming 40 years will be in the poor half of the world. They will raise the population of the poor world from approaching 3.5 billion to about 5.5 billion, making them the poor two-thirds.Sounds nasty, but based on Pacala’s calculations — and if we assume for the purposes of the argument that per-capita emissions in every country stay roughly the same as today — those extra two billion people would raise the share of emissions contributed by the poor world from 7 percent to 11 percent.Look at it another way. Just five countries are likely to produce most of the world’s population growth in the coming decades: India, China, Pakistan, Nigeria, and Ethiopia. The carbon emissions of one American today are equivalent to those of around four Chinese, 20 Indians, 30 Pakistanis, 40 Nigerians, or 250 Ethiopians.Even if we could today achieve zero population growth, that would barely touch the climate problem — where we need to cut emissions by 50 to 80 percent by mid-century. Given existing income inequalities, it is inescapable that overconsumption by the rich few is the key problem, rather than overpopulation of the poor many. -- source link
