the earth now supports 6.5 billion people, the scientific community estimates the most that the earth can support is between 11 and 14 billion. If we are going to do something like this, I believe now is the time.

Where are you going to get a new earth from?

I hope that in 5 billion years. We have somewhat evolved beyond this planet. Besides we won't have enough land or fossil fuels to last the next five hundred. I can hardly imagine five billion years from now.

First: we are constantly being bombarded by millions of asteroids. The only thing that saves us is the atmosphere, which vaporizes them.\n\nI'll do a little math. We'll consider the solar system to end after the Oort Cloud, 100,000 AU or 9,300,000,000,000 miles. Therefore, the solar system has a volume of 4/3*π*(9.3*10^12)^3, or ........ about 3.369*10^39 cubic miles. The Earth has a volume of about 2.08*10^12 cubic miles.\n\nIn short, the Earth takes up 0.00000000000000000000000006% of the solar system. Even with trillions of potential threats, the chances are next to nothing.

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.

The earth had like 20 babies.  They are other planets.  They are all grown up and have moved away to other galaxies.  Now the earth uses birth control, so this doesn't happen any more.

Age of the "world," taking Earth as the "world"...scientists estimate about 4.54 billion years.  Estimate was confirmed by radiometric dating using rubidium (and other decay series).  Radiometric dating is something I study, so that's why I trust this estimate.

Well, that depends.  There is evidence of algae at 3.5 billion, probably photosythetic cells by 2.0, and clear plants by 400 million.  With a 4.6 billion year old earth, that's 76%, 43%, or 8.7% of the time.

6,525,170,264 was the world population in July 2006 .\n\nMaybe they know of some space aliens watching .

Taking the present population of the earth as 6.5 billion, at 2 sq ft per person, we would require 13 billion sq ft.\n\nThis works out roughly to 1207 sq km.\n\nThe Isle of Wight being only 381 sq. km., it would be a tad too small.\n\nGoogling for 1207 sq. km. gets me the city of Los Angeles, or the island of Lifou, in New Caledonia!

not likely- no matter how many humans populate the planet, we make up  a very small fraction of the total mass of the earth,which is the same as it always was, since very little material has been removed from the earth since it was formed. The tsunami didn't affect the earth's orbit, it affected the rotation of the earth around its axis(sped it up by about one-billionth of a mile per hour) but didn't change the speed at which we travel around the sun(orbit) at all.no matter how we redistribute material around the planet we only change the weight distribution of the planet by a very,very small fraction so the effect will be unnoticable. the effect on this planet from human activity of any kind is much smaller than we think- greenhouse gas levels were far higher during the age of the dinosaurs than they are now (and humans didn't exist then). the amount of iron and other minerals we have taken out of the ground accounts for about onemillionth of a percent of the total amount still there. from out in space, you can't look at the earth and see anything that would suggest we live here, except the Great Wall of China and the light from our cities at night, so how great of an impact do we really have?

Don't see... many... Buddhists? Don't live in China, do you? Estimates vary, but even low estimates are around 300 million worldwide. That's a little more than the population of the entire united states, for comparison.

The world's population is following a very standard growth curve, which every population of animal follows.  It begins with a lag phase, then exponential growth, and then, as the species begins to reach equilibrium with what their environment can support, begins to level off.  We are just starting to level off - world population growth is slowing.  It is projected that the world will top out at 9-11 billion people.  This will not be an overcrowded situation - humans currently occupy only a tiny fraction of the planet.  Doubling that will not be a serious problem.\n\nThat being said, obviously there are limits to how many of us earth can sustain.  The biggest problem right now is that the birth rate is way too high in places that cannot support their population.  This problem will correct itself - it has to.

Old age, the Earth will gradually become uninhabitable over a very long period of time until the time comes when the few million people that are left only have legends about how the planet once supported billions.\nNuclear war,  pandemics, possible global warming would be as hiccups along the way.

There are none! Cause the world hasnt even been here that long! This world has only been here lyk ovr 2000 years! Im assuming u eithr believe n evolution or ur jst stupid lol! Cuz seriously y would u think the earth has been here that long! Im not a big god person but sitll god created the world n if it was here 4 more then 180 million years i think he would tell us that! Jst trust me ppl who think our world is that old r jst crazy! Cuz it aint true! Cuz if it was y is our year 2006? Y wouldnt it b 180,000,000!!! Honestly if the world was here that long the year would b that high! N if u dnt believe me then ur crazy cuz ppl who think the earth is that old r jst crazy!
