Ok, tema muy bien desarrollado
el humano tiene expectativas sobre la capacidad de mantener a la población. pero dados los factores naturales y biológicos en poco tiempo el aumento dramático de la población hará que sea insoportable vivir con tanta gente. ya que actualmente somos 6.000.0000.000 de personas que diariamente deben alimentarse y diariamente nace mas población.
What is Urbanization?
What is rural Migration?
What is Scarce resources?
What is the effect of urbanisation on the standard of living?
Given the wherewithal to do so, humans have aesthetic expectations in their daily lives. While the earth might be able to hold many more than the current human population of six billion (estimates of the human K with current technology go as high as 50 billion) at some point people will find it unacceptable to live with the crowding and pollution issues associated with a dramatic increase in population.
The qualitative measure of a person's or population's quality of life is called its standard of living. It is associated not only with aesthetics of surroundings and levels of noise, air and water pollution, but also with levels of resource consumption.
Americans have one of the world's highest standards of living. While there are many who live in poverty in the United States, on average they have relatively small families, large homes, many possessions, plentiful food supplies, clean water and good medical care.
This is not the case in most of the developing world. While many nations have larger average family sizes, they have smaller homes, fewer possessions and less food. Supplies of clean water may be scarce and medical care may be inadequate. All people desire to have adequate resources to provide good care for their families, and thus population in most developing countries are striving for standard of living of developed nations.
Is it possible for all six billion people on earth to live at the same level of resource use as in the United States, Japan and Western Europe? With current technology, the answer is "no". However, this does not mean that the people of one nation are more or less entitled to a given standard of living than those of another.
What it does mean for citizens of nations like the United States is that we must reduce our current use of resources. Of all of the food purchased by the average American family, 10% is wasted. In addition, because most Americans are not vegetarians, they tend to eat high on the food chain, which requires more resources than a vegetarian diet.
Humans also produce a great amount of "quick waste". Packaging that comes on food in the grocery store is a good example of quick waste. The good news for the environment (from both a solid waste and a resource use standpoint) is that we can easily reduce the amount of goods and resources that we use and waste without drastically affecting our standard of living.
For example, the amount of packaging used for goods could also be reduced. Reusable canvas bags could be used for shopping and plastic and paper grocery bags could be reused.
