Max Gerber] I am often asked whether I agree with the new group selectionists, and the questioners are always surprised when I say I do not. After all, group selection sounds like a reasonable extension of evolutionary theory and a plausible explanation of the social nature of humans. Also, the group selectionists tend to declare victory, and write as if their theory has already superseded a narrow, reductionist dogma that selection acts only at the level of genes. In this essay, I'll explain why I think that this reasonableness is an illusion.
Changes in atmospheric composition and consequent global warming. Rich countries with high population densities have low rates of infant mortality. It results in human threats including the evolution and spread of antibiotic resistant bacteria diseases, excessive air and water pollution, and new viruses that infect humans.
Increased chance of the emergence of new epidemics and pandemics.
However, rich countries with high population densities do not have famine. Poverty and inflation are aggravated by bad government and bad economic policies. Many countries with high population densities have eliminated absolute poverty and keep their inflation rates very low.
However, this problem can be reduced with the adoption of sewers. For example, after Karachi, Pakistan installed sewers, its infant mortality rate fell substantially. Laws regulate and shape politics, economics, history and society and serve as a mediator of relations and interactions between people.
It was even speculated by Aldous Huxley in that democracy is threatened due to overpopulation, and could give rise to totalitarian style governments. David Attenborough described the level of human population on the planet as a multiplier of all other environmental problems.
According to Paul R. We want to build highways across the Serengeti to get more rare earth minerals for our cellphones. We grab all the fish from the sea, wreck the coral reefs and put carbon dioxide into the atmosphere. We have triggered a major extinction event A world population of around a billion would have an overall pro-life effect.
This could be supported for many millennia and sustain many more human lives in the long term compared with our current uncontrolled growth and prospect of sudden collapse If everyone consumed resources at the US level — which is what the world aspires to — you will need another four or five Earths.
Williams  argue that third world poverty and famine are caused in part by bad government and bad economic policies. Resources[ edit ] Youth unemployment is also soaring, with the economy unable to absorb the spiraling numbers of those seeking to enter the work force.
Many young people do not have the skills to match the needs of the Egyptian market, and the economy is small, weak and insufficiently industrialized Instead of being something productive, the population growth is a barrel of explosives. It also depends on how resources are managed and distributed throughout the population.
The resources to be considered when evaluating whether an ecological niche is overpopulated include clean waterclean air, food, shelter, warmth, and other resources necessary to sustain life.
If the quality of human life is addressed, there may be additional resources considered, such as medical care, education, proper sewage treatmentwaste disposal and energy supplies. Overpopulation places competitive stress on the basic life sustaining resources,  leading to a diminished quality of life.Anchor baby" is a term (regarded by many as a pejorative) for a child born in the United States to a foreign national mother that unlawfully resided in the United States at the time of the child's birth.
A ccess, whether to someone or to something, is a valuable commodity these days.

But the phrase is angering some groups, including the National Association of . Trump said, "Many of the great scholars say that anchor babies are not covered" by the 14th Amendment. There are respected academics who argue that the 14th Amendment allows but does not require children of illegal immigrants to receive citizenship just by virtue of having been born on American soil.
