First they build all these fast food joints, then they litter the countryside with all the packaging from the fast food joints.  Then, they build all these stick houses all over and put the odd tiny park space for their children to play.  Then smog fills the air and everybody gets asthma, and hay fever.  And the overcrowded areas cause road rage and people are impatient with each other for not moving fast enough when they are in a hurry.

Pollution and DDT can cause poor environments.  All the oil and logging industries causes detriment to fishing of salmon for eagles.  As civilization expands their habitat shrinks.

If the human race is going to evolve any further we must look for a new place to live.  We are destroying this planet.

I do.  What are we going to do though?  With a rising population you have to put them somewhere right?  I'm for setting aside large chunks of land as reserves now while we have them to set aside.  Unfortunately, our culture's attitude towards land usage and the environment in general is ignore, ignore, ignore, panic.  I don't think we've reached panic yet, but we will. I'm not for the grid system either.  I think that is one of the worst ideas of all time.  Like in Arizona, for example, the land that can be developed, and the land that can't, are arranged in a checkerboard.  So what happens to animals that roam or migrate?  When all the 'boxes' of land have been developed around the reserved block the animals inside are cut off - the population either has to move to another block or it dwindles and possibly dies off.  Plus they have all kinds of run ins with the surrounding communities.  Some people that live in these communities think that it doesn't adversely affect the environment but it does.  They say "What do you mean?  The deer aren't dying off - I just had one in my backyard the other day."  They don't see how that is a problem.  The checkerboard is not a solution - it just worsens the effect of development.  And Phoenix is a classic example of urban sprawl.  Like a cancerous tumor its neverending grid of streets spreads out in all directions.  We aren't there yet - and we may not see it in our lifetimes - but the earth is so going to kick all of our a**e* eventually.   And, as a cultural, we will stand bug-eyed and bewildered - scratching our collective empty head over how it came to this.

The population tends to increase faster than the food supply.\n\nIn general, at least with humans, the population increases exponentially while the food supply increases linearly leading to shortage/hunger.

The man's name was Thomas Malthus.\n\nBasically, that unless human population would introduce severe limiting factors, the exponential growth would lead to a catastrophe.

compare the rate of it now to 50 years ago (many people will be alive in 50 years).  Then compund that to what it would be in 2056 (eek, I'd be 75) and tell what would be affected.  Or just tell them how hot their ass are going to be when they are old and trying to stay alive.

Honestly, the effects are endless. I'm currently working on this topic for my Master's (that what I should be doing right now) and when you really start to delve into the study of it, it's really quite disgusting because it affects everything we rely on to live.  But to sum it up, when the land is polluted, it really leads to pollution, destruction, and loss of everything else. The pollution makes it way into our water sources, kills plants, and  consequently, that is one cause that leads to the loss of animal species.  Polluted land is often treated with chemicals to "clean it up" that ends up in the soil and poisons our food sources.  The issue really is complex, but I encourage you to study it further.  You won't look at this world the same.

It's short term gain for long term pain. We need to think about the future inhabitants of our planet, rather than doing things like polluting the earth, just so we can make more products, etc. Sometimes people are shortsighted, and that is one reason the environment is in danger.

Each ecosystem has what is called a "carrying capacity" for the organisms. This is where birth rate = deaths.\n\nThis is because organism's grow in number until the demand or limit of one (or more) factors for life become exceeded.\n\nSome factors are things like water, living space, nutrient source (food) and waste build up.\n\nPopulations can exceed the carrying capacity for a short time but eventually the limit of the environment brings the population back down.

INTRODUCTION\nPollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.\n\nThere are two main categories of polluting materials, or pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. \n\nNondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation.\n\nTYPES OF POLLUTION\nPollution exists in many forms and affects many different aspects of Earth’s environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions.\n\nThe effects of these pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds.\n\nA  Air Pollution \nHuman contamination of Earth’s atmosphere can take many forms and has existed since humans first began to use fire for agriculture, heating, and cooking. During the Industrial Revolution of the 18th and 19th centuries, however, air pollution became a major problem. As early as 1661 British author and founding member of the British Royal Society John Evelyn reported of London in his treatise Fumifugium, “… the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs. This is that pernicious Smoake which fullyes all her Glory, superinducing a sooty Crust or Furr upon all that it lights.…”\n\nUrban air pollution is commonly known as smog. The dark London smog that Evelyn wrote of is generally a smoky mixture of carbon monoxide and organic compounds from incomplete combustion (burning) of fossil fuels such as coal, and sulfur dioxide from impurities in the fuels. As the smog ages and reacts with oxygen, organic and sulfuric acids condense as droplets, increasing the haze. Smog developed into a major health hazard by the 20th century. In 1948, 19 people died and thousands were sickened by smog in the small U.S. steel-mill town of Donora, Pennsylvani
