why growth of population can't be controlled by proper way which is surly the cause of human imbalance?

For one thing, different people have different notions of what the "proper way" is.  Those with religious reasons will refuse to wear condoms.  The Catholic Church prohibits this as a birth control measure but, recently, Pope Benedict is advocating it to stop AIDS but only to stop AIDS from spreading.  Half the problem is access to birth control measures and the cost. Poor people are the ones who procreate all the time and they can't afford birth control. The other half of the problem is ignorance. Some people are just not informed about birth control.

Overpopulation, all problems can be tied into population increase...think about it.

Nature will take care of that problem. Once the Earth's resources are depleted and human population starts to wane then economies will crumble (a healthy economy is built around a growing population), famine and disease will be rampant. At least 80% of the human population will perish.\n\nNow aren't you glad you asked.

I've also heard of studies similar to those you're referring to; I agree 100% w/ you that high population density is a pretty feasible reason for homosexuality and violence, these may well be nature's "control mechanisms" for avoiding LOCAL overpopulation. As far as the whole world being overpopulated, I don't agree w/ you.... food production nowadays, for example, could feed more than 100% of the world's population adequately if equally spread among all human beings; furthermore, global birth rates are rapidly declining, which could actually lead to global UNDERpopulation just a few centuries from now.

The human population did NOT start out as two (this readily confirmed by analysis of genes found in different groups of humans across the globe).  Also, Earth is some 4.57 billion years old.  Additionally, humans have existed for several million years.\n\n\nOkay...I'll humor you...\n\n-a human generation is 20 years\n-there are only 300 generations in 6000 years\n-before healtcare each generation more or less had enough time to mature and then have offspring\n-human births are risky compared to other animals and can possibly kill the mother\n-average lifespans before healthcare is estimated 20-35\n-sexual maturity generally occurs between 12-14\n-lifespan has only started increasing since 1800 so that is 200 years or 10 generations\n-Therefore to get and maintain 6.5 billion each successive generation had to have an increase of 21,666,666.667 individuals or more per generation to get from 2 to the 6.5 billion in the necessary time AND maintain population size.\n\nTherefore it is NOT possible for humans to have started from a population of 2 and increase up to 6.5 billion considering all factors involved.

Think of it this way - not everybody in the world is having a child, or 2 children. And besides, there are ways that our world can cope with an expanding population. It's in countries where we can't cope that there's a problem. Have all the babies you want, so long as you can nurture them and care for them. Just don't build a giant house and don't support subdivisions. That's where it starts to hurt the Earth.

None at all. The human gives himself too much importance. Essentially, the role of mankind is as unimportant as the role of rocks, mosquitos and, actually, anything in the universe. However, mankind would not survive had it accepted the absolute pointlesness of its existance and so, our elevating of humanity's status above something what it really is seems only natural.

More births than deaths per year leads to population growth.\n\nIncreased human longevity; improved healthcare; reduced child mortality.\n\nCordially,\nJohn\nhttp://www.GodSci.org\n[God and Science]

There is definately a correlation between the increase in the population of the world and the destruction of the environment.  But remember that correlation is not causation.  Just because two things increase at a similiar rate, does not mean that one causes the other.  The causes of the destruction of the environment, stems from our inability to responsibly advance our society.  It comes from our poor practices as a global society and as local communities.  It comes from our inability to think about how to do things efficiently and effectively while taking into account the environment and our long term comfort and survival.  It also comes from our rapidly increasing technology, combined with our not so rapidly ability to deal with the waste and biproducts that come along with technology.  Simple example: car and smog.  I hope this can start your thought process in the right direction.

It is the theory that - and pardon the layman's use of terms and simplification - man's population growth will overcome the ability of its agricultural resources to feed it. Given two groups of roughly equal people, the one with superior agricultural resources will grow faster than the one without (or with fewer) resources. \nThe theory appears to hold validity when applied to the animal world, but becomes more difficult to predict when the point of overbudening will occur with human beings. This may be due to a number of reasons, not the least which of them are technological advances in agriculture.

The only thing that comes to mind is population growth.  The more people (or whatever organisms) there are, the faster their population grows.

Immigration of people to the planet causes world population to rise.  Emigration of people leaving the planet causes world population to fall.\n\nDuh!

I'm in total agreement with you. it's the same for any country. over population will create problems with jobs. are system would not be able to support everyone in need of help.

High birth rates are a global problem.  It would be better if everyone limited themselves to one or two children.  That kind of global thinking won't happen, though, until education is valued by governments and all people are made aware of the world overpopulation crisis.

it is the survival of the species. gal n guys are created to make sure that mankind don't become extint on the earth. so all are created to have as much sex as possible with as many diffirent people as they can. so that they can make as many babies as possible. but there is a mis calculation in the natural process we had over produced. but any how as happened in Japan the population is shrinking now. it could be that the natural process is working.

There is a phrase that scientists use called Carrying Capacity which is the amount of a species that the environment can hold due to limiting factors which are any biotic (living factors) or Abiotic (nonliving factors)factors that restrict the existence, reproduction, or distribution of organisms. When the number of a species reaches or exceeds the carrying capacity then limiting factors begin to take effect such as the amount of food available. Also when the carrying capacity is exceeded competition begins for food, shelter, and reproductive rights. There are three types of growths: stable  growth, rapid growth, and slow growth.An example of stable growth would be the U.S. an example of rapid growth would be China. Since not all countries have the same growth rate it is hard to say whether there are too many people in the world. So really it is a matter of opinion. In some countries there are to many people, such as third world countries, but in other countries there are not too many people. As for what we can do about it, there is nothing we really can do besides what China does (limits each household to one child). What happens is when the carrying capacity is exceeded there is not enough food, shelter, etc. for all the individuals in a population. As a result those individuals die and the population's size eventually falls below the carrying capacity(which is what happens in most third world coutries). This is referred to as 'Survival of the Fittest'. It's horrible to imagine but it's the truth and theres not much we can do about it.

Matter and energy is constant in the Universe.  The fact that more people are born doesn't necessarily mean that the total mass of all compounds on the Earth has increased.  The compounds have simply been redistributed.  Therefore there would be no increase in weight
