Human decrease the natural resources.

the human population is growing and we are wiping out other species. We are also polluting the air and killing off animals.

If fertility remained at current levels, the population would reach the absurd figure of 296 billion in just 150 years. Even if it dropped to 2.5 children per woman and then stopped falling, the population would still reach 28 billion.

pollution (thank you coal), Trash in landfills, using up resources.

The Human Population has grown tremendously since the Black Death and The Great Famine in 1350 when it was about 370 million. Human Population is effecting earth in a bad way we are using up all if earth's resources!

"Go Forth And Multiply!" That's what the human population has successfully been doing for thousands and thousands of years, expanding, exploring, migrating, conquering, utilizing, evolving, civilizing, industrializing, and now, destroying the very land upon which we live.

Many feel (as has been the case throughout history) that the major international wars to be fought in the future will continue to be over natural resources. Power conflicts and self-interest will perhaps mean that there will be gross violation of basic rights and death or misery for millions of innocent people. Throughout history, most wars have had trade and resources at their core (leading to ideological battles) fueled by imperialistic motives. In the future, while this pattern is likely to continue, as resources get depleted and wasted in these wars (hot and cold), additional conflicts and contention will arise through access to even more limited resources.

Many of us have grown up learning and being told that 6 billion is too much and this "over population" is primarily impacting the planet's ability to cope. But is that really the case? Sure, the planet is facing incredible stress. But how much of that is due to large populations, and how much is based on other factors, such as how we choose to live, how we produce, consume and waste our resources? The poor are numerous, but as we shall see, consume far less resources of the planet, for example.

Studies point to ecological limits to sustain people, but these limits can be different, based on the way we consume resources etc so it is hard to say for sure what over population means let alone if we are at some threshold, below, or above it. The information understood so far provides valuable insights and is very important to consider, nonetheless. Yet, the figure of 6 billion and literature about over-population naturally looks to the poor regions where there are high populations and environmental degradation as the problem.

In the poverty section of this web site, we see numerous causes of poverty, and many are found in unfair economic and trade agreements from wealthier nations and institutions. While it might be an oversimplification to say the poor are victims, a lot of poverty, if not the majority is caused by factors which the poor themselves often have no control or choice over. Yet, at the same time the poor seem to get the blame for burdening the planet. Is this the case? While the concern for the environment and the planet's health is usually the central issue here, is there a risk of addressing the issue in ways that may not get to the root causes of any problems that are perceived to require serious attention? This section of the globalissues.org web site attempts to look at and introduce some of these issues.

The effects of population growth are varied and vast. While population growth, of any species, may be beneficial to a certain extent, there may come a time when the number in the population exceeds the natural resources available to sustain it. This is referred to as overpopulation. The consequences of such an event are severe and major.

The population growth of any animal, if left uncontrolled can become burdensome. Farmers have noted, for many centuries, what the effects of an uncontrolled predator population can do to livestock. Once their natural prey run out, or are harder to find, the predators may turn to domesticated animals, despite the risks. This can cause a severe hardship on any family depending on those animals for survival.

However, when most think of a growing population, they do not think of other animals. The prime fear in most people's minds is the population growth of their own species. As humans leave a much larger footprint on the environment than any other creature, uncontrolled overgrowth can be especially devastating.

First, as the population grows the opportunities for quality, available housing may become an issue. More people crowded into less space is not a good combination in any locality. As space is taken up, it becomes more valuable. Eventually, it begins to affect to poorest in the area. In the long run the effect of population growth may be substandard housing or homelessness.

The human population grows every day, and we are using more nonrenewable resources.

The higher the population, the more resources used.

The world population is the total number of living humans on Earth. As of today, it is estimated to number 7.13 billion by the United States Census Bureau (USCB).[1] The USCB estimates that the world population exceeded 7 billion on March 12, 2012.[2] According to a separate estimate by the United Nations Population Fund, it reached this milestone on October 31, 2011.[3][4][5] The median age was 30.4 years in 2012 and is expected to rise to 37.9 years by 2050.[6]
The world population has experienced continuous growth since the end of the Great Famine and the Black Death in 1350, when it stood at around 370 million.[7] The highest rates of growth – global population increases above 1.8% per year – were seen briefly during the 1950s, and for a longer period during the 1960s and 1970s. The growth rate peaked at 2.2% in 1963, then declined to below 1.1% by 2012.[8] Total annual births were highest in the late 1980s at about 138 million,[9] and are now expected to remain essentially constant at their 2011 level of 134 million, while deaths number 56 million per year, and are expected to increase to 80 million per year by 2040.[10] http://en.wikipedia.org/wiki/World_population

The higher the population on Earth, the more resources there are being used up.

There are now over 7 billion people living on earth.
Approximately 4.7 billion people live in low and middle-low income economies. In contrast, 65 high-income countries have a combined population of about 1 billion less than one-sixth of the world's population.
Nearly one in four people in the world is young, between age 10 and 24; while 85 percent of all adolescents live in developing countries.
The world population is growing by about 0.8 percent, or almost 80 million people, per year.
As of 2006, approximately 48.8 percent of the world's population lived in urbanized areas. In developing countries more than one third of this growing urban population lives in slum conditions.
Every second 4.3 people are born worldwide; while every second 1.8 deaths occur. The world population has a net gain of 2.5 people every second.
In Sub-Saharan Africa 55 percent of children under 5 have never been registered; worldwide nearly 50 million children each year are not registered and begin life with no identity.
