Is Overpopulation Humans biggest disaster ?

Question

Think about it, if we had less peopkle we would stop using so much energy. Are Humans out of wack with Nature ? do you expect a correction soon ? IE mass die offs,

With Less Humans we would have less global warming .

Answer 1

no not really if your that concerned...kill yourself.

Answer 2

A quick lesson on population dynamics: all living creatures (plant, animal, otherwise) will increase in population at an exponential rate if allowed to do so. While critters with a high reproductive rate (such as, for instance, fruit flys or mice) will have a much steeper exponential curve, even critters with slow reproductive rates (elephants, whales) will over time achieve an exponential population increase curve. The important words here are 'if allowed to do so'.

Predation, competition, and other factors serve to provide natural 'checks' on the population of critters. While these checks remain in place, the overall health of a population (and, indeed, the ecosystem) remain in balance. However, cyclical changes in predator-prey relations, desease, or other outside forces can change the dynamic, some with dramatic results. A good example of the preditor-prey dynamic would be the lynx-horseshoe hare data gained from trappers in Canada from the 1800's through the middle 1900s.

Humans are destined to have the same sort of exponential growth curve as any other animal (yes, we are animals). War, desease, and competition for finite resources have been checks on the population growth in the past, but technology (among other factors) have eliminated or reduced the effect of some of these checks. With no other 'natural' preditors, human populations have risen essentially unchecked over time.

Reality states that we cannot grow exponentially forever. Forces such as food availability and desease cannot be conquered by technology forever. Worldwide growth rates are slowing as the result of increased education in the third world, global health issues, etc. Some scientists believe that eventually the growth will tend toward zero, but this will not happen for many years.

What effect does this have on the rest of the world? The greater the human population, the greater the stress on the global system. Resources are finite, and if we as humans use them, it reduces the amount available for other critters. As some previous answers have stated, there are some that care not for the plight of other creatures nor the ultimate damage that humans are inflicting on the globe. While it is their right to do so, I sincerely hope that the world that we will give to our decendants will be rich and full of life, and not a bland, uninspiring globe dominated by humans and the creature that benifits from humans the greatest, the rat.

Answer 3

just about everything comes from that
peoples bad habits are multiplied billions of times over

over popúlation and some related effects

in Mexico ,South America,Asia etc. the expanding
populations are consuming forrests for agriculture and habitat.
In the last 50 years world population has doubled a faster growth ever since we became homo sapian.
the effects on the environment are
,erosian,over pumping of carbon aquifiers(deep wells)
desertification,rising seas,land loss,deforrestation,watershort...
excess carbon emissions,mass extinction of species and global warming.

DEFORRESTATION if it continues ,is that we could end up looking like Mars.Without an atmosphere ,without water,without air,with out life

the forrests make most of the water that we can drink or use for plant growth(sweet water)
some is condensed from the sea but that reaches only the coastel aereas .
the bulk ,comes from the forests ,and the rivers come from the rainfall which comes from the trees ,
and the trees with precipitation,feed the rivers when it is not raining and keep them running all year round.

If we kill all the trees,we kill the rivers .we kill the rain. we kill us.
the trees also absorb the heat in the day and heat up the place in the night ,so they keep the temperature confertable to live in.

in the dessert the nights are freezing cold and during the days you burn up

CARBON MONOXIDE
the trees absorb carbon emisions ,which is poison to us and they produce oxygen which we need to breathe.

so in short the trees produce the air that we need to breathe.
they also produce wood which is usefull and a wide range of food such as fruits

deforestation must be stopped before desertification goes out of control and consumes the planet.

DESERTIFICATION
the sahara is growing by 7 kilometres every day.
two major desserts in northern china are growing together making one giant dessert and,causing dust storms so making thousands of people refugeese

the trees evaporate a mist which ,which protects us from the strong rays of the sun .

the planet is drying out at an alarming rate.

in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth ,and there were no desserts .
Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.

Bad agricultural practises is turning vast teritories into desserts ,because of over grazing and the exessive pumping of carbon aquifiers ,the surface aquifiers already having been depleted.
And the use of fertilisers and heavy machinery that compacts the ground which raises the salt in the soil.
Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.

And because agricultural lands are lost, farmers are forced to cultivate highly erodable lands, to keep up with the growing demand for food.an extra 70 million people each year and this is increasing
the world population has doubled in the last 50 years the fasted increase ever since the first homo sapian.

EROSION
soil erosion is almost always as a result of human intervention.
the trees are cut down and these trees existed to provide a cover against the rays of the sun which now dries out the soil ,and the wind can than easily blow away the dust that is formed ,------this is wind erosian

because the trees are no longer there, whose roots bound the soil together ,and because their canapies of foilidge no longer exist the rain now has easy acces to the unprotected ,now dry surface and the rain waters wash away the top soils ,------this is water erosian

In Mexico indigenous peoples are cutting down trees to plant corn ,this land is productive for a few years before it becomes poor and useless for farming.

MUD SLIDES
the roots of the trees that have been cut down rot and tunnels are created with their diaaperance ,with heavy rains thes tunnels fill up with water and the soil lift and moves down wards .

mudslides are caused and large parts of the mountains are exposed to the rock.

the mud destroys the lands beneath and the exposed areas NEVER recover leaving the area with out vegetation forever

WATERSHORTAGE,OVERPOPULATION
each year 70 million more people are consuming water but this is ,but a small part of what agriculture uses.

so our consumption of water is ever increasing and our drinkable water supply is shrinking because of polution ,and the production of potable water is less all the time because of deforestation.

Answer 4

The entire population of the planet could be housed in Texas with a population density less than that of Paris. There is no overpopulation.

Answer 5

Well as the population continue to increase it will reach a point where we have a war that could kill 3 billion people.

Answer 6

1) out planet is in no danger, global warming is bullshit
2) there is more then enough land on this planet to hold everyone
3) mess die offs? what the hell does that mean

Answer 7

The hand that rocks the cradle rules the world.

Educate females.

Answer 8

Unwillingness to aspire to greatness is the greatest loss.

Yes, there will be a genocide.

Live well, and you will suffer no regrets as you perish.
