Ecological considerations

If we burn any number of different fuels, we produce pollutants and lots of CO2. Wind and water, both excellent renewable energy sources, carry their own environmental footprints.

Here population nearly doubled in 10 years, and home prices tripled and urban planning circles hailed the boom as the new America at the far exurban fringe.

But others saw it as the residential embodiment of the Edward Abbey line that "growth for the sake of growth is the ideology of the cancer cell. Owners of 1 in 10 mortgages owe more than their houses are worth, and many just walk away.

Without vested owners, vandalism runs rampant and the place becomes a slum. Through immigration and high birth rates, the United States is expected to add another million people by Developers plowed up walnut groves and vineyards to pay for services demanded by new school parents and park users.

A lesson can be learned from cities like San Francisco, Portland, Seattle and San Diego, which have stable and recovering home markets, have fairly strict development codes, trying to hem in their excess sprawl.

Instead, the free-for-all cities like Las Vegas, the Phoenix metro area, South Florida, this valley - are the most troubled, the suburban slums. Build it and they will come, say the developers, confident that growth is always the answer.

They have no idea about carrying capacity. And most people still do not realize that economic hard times are related to carrying capacity. With so many of us burning fossil fuels, gobbling up renewable resources, and generating toxic trash, our life support ecosystems are threatened.

In the central North Pacific Ocean gyre, swirling plastic fragments now outweigh plankton 46 to one. CO2 in the atmosphere is higher today than anytime in the pastyears.

Nearly one in four mammals is threatened with extinction, and worse - one in three amphibians and a quarter of all conifers. In many parts of the world, including the High Plains of North America, human water use exceeds annual average water replenishment; by 1.

Unsustainable farming practices cause the destruction and abandonment of almost 30 million acres of arable land each year.

The number of humans is still increasing by 1. Even though China is only growing by 0. Many argue that a decrease in human numbers would lead to a fiscal catastrophe, seeing that, in the last years, unprecedented economic growth has been accompanied by an equally unprecedented increase in world population.

During the s and s, up to half of world economic growth was likely due to population growth; Georgetown University environmental historian John McNeill explains: More hands, more work, more things produced. Slow population growth, and economic growth will likely slow as well unless advances in productivity and spending increase at rates high enough to make up the difference.

This perhaps explains why population policy is not a popular issue. Instead We should be looking at per capita GDP, which corrects for population growth. Population decline may slow economic growth on a nationwide basis, "but it would not necessarily reduce per capita wealth or, indeed, per capita growth.

An economic "slowdown" that results from slowing and eliminating population growth is distinctly different from that caused by a credit crunch or the messy bursting of a speculative bubble. In many poorer nations, having more children means increasing the supply of labor, and lowering wages.

While reducing population growth in an orderly fashion promises more economic good than ill, it will bring about social and economic challenges that even proponents of shrinking the population do not dismiss lightly. Of particular concern are the challenges associated with reducing the number of working age people relative to retirees.

If we have fewer people, we will be spared the problems caused by overpopulation, save on natural resources, and in the long run be more able to provide for the social security of our aging population. New York Times Population Debate.

It appears The New York Times is attempting to separate the population issue from US immigration and make them into two unrelated issues. On average, over 1 million foreign born people are granted permanent residence status each year.

Environmental Issues in Construction

By adding million people, the US is set to add into its borders the equivalent of all the current citizens of Mexico and Canada combined by This will result in: US population sky-rocketing by over million people. Demand for the ground-water, open-space and farm-land dramatically surging.

Wages for lower-skilled, less-educated Americans plummeting as excess service labor swamps the market. Roads, schools, subways and grocery stores becoming even more crowded. Representative democracy weakening as each elected official serves a drastically inflated constituency.

If Congress were to set immigration policy to allow forpeople to be invited into the nation per year US population would be 80 million less than is it currently projected to be at mid-century. Up to now the US has been a rich nation, but the strain on its resources and that on other countries it takes from is beginning to show.Within a few minutes, flocculation of the solids should begin to occur.

You should start to see a clear layer of water forming very quickly as the solids settle to the bottom. Future Environmental Regulation of Fracking A continuing complaint of the environmental community is that oil and gas production generally, and fracking in particular, is largely exempt from the provisions of most federal environmental laws and their state analogues.

RESISTANCE TRAINING FOR THE MANAGEMENT OF TYPE 2 DIABETES. To examine whether resistance training is an effective form of exercise for managing glucose homeostasis in type 2 diabetes, a comprehensive review of the literature was performed using four electronic databases (MedLine, EMBASE, CINAHL, and Sports Discus).
