Is the Earth getting heavier and heavier with so many people being born and cities built?

Mass arrives from space, and departs to space. But also energy arrives from space (mainly from the sun) and is converted into mass through biological processes.

The Earth is in danger of becoming almost totally inhospitable for most higher life forms.  Unless we start being more intelligent and get population and resource management under control, the Earth will do if for us.

Every day 400000 babies are born, 150000 people die for a net increase of 250000 human beings a day.\n\nCurrently the worldpopulation increases with 90 million a year, or about 1.4%. We are crowding 6500 million people on the planet.

Good question.  I think you may be on to something.  Our ancestors went from small clans roaming from cave/tree to cave/tree.  Then grew from towns and cities to states and countries in just several hundred years.  So as beliefs between people become more assimilated we may see a further melding of the worlds population into larger and larger countries.  Might take hundreds of years?

I don't know about loading and unloading or building skyscrapers, but the last two definitely put stress on the earth that could contribute to earthquakes.\n\nFilling reservoirs behind dams adds an enormous weight of water where there was little water before and this weight can put pressure on the earth below.  This is a concern with the Three Gorges Dam in China.\n\nTaking out ground water can also have an impact because it leaves nothing behind, so you are left with dry rock with lots of holes in it that is less stable than it was before with all the water inside of it.

it's impossible to count. new islands are forming all the time and others are sinking. these islands are all very small. but even manhattan will sink eventually.

well city has tons of buildings and the buildings have weight. so they will add more pressure to the tectonic plates and cause them to move faster i guess. There are tectonic plates which meet at one point and they either slip, slide or grind agaisnt each other. and when they slip, this causes the earthquake. so then the more weight on the plates means also more pull. so the plates move faster or something. my guess. but i doubt it has any effect

a lot, over a  billion people

Partly.\nThe increasing emission of Green House gases in causing Global warming which is making the world's climate go topsy-turvy\n\nNow you have Summer heat waves in Europe, Snow fall in Dubai, the killer Hurricanes\n\nPerhaps it is time for Mankind to step back and think as to why these are happening\n\nBut I should state that Earth Quakes are not quite related to this effect (but then again, you would never know)

Scientists are now saying the Earth is a little lighter than we thought. The calculated weight is 5.978 sextillion metric tons, or 5,978 followed by 18 zeros. But the latest measurements show the true weight is actually 5.972 sextillion metric tons. So, does this mean the Earth is losing weight? \n\nActually, the answer is no. The truth is, one of the constants used to calculate the weight of the Earth was off. The force of gravity, shown as the capital letter G, is a little tricky to measure. Scientists have come up with many different numbers, and each one gives us a different number for the Earth's weight. \n\nScientists at the University of Washington found a more precise way to measure G. And now that they have this more exact measurement, they have found the real weight of the Earth - they think. They warn that their findings may still change, so don't use the new weight in your science homework just yet. \n\nWho knows, maybe the Earth is losing weight!

yes, there are too many people living in this earth. if it continues to be this way, then sooner or later the whole earth will be crowded! and the only way to stop it is if people used protection! and if they are too young to have sex then they should wait until they are older or at least use protection or else. no way do i want too live in a crowded world! do you? but we might already be dead before it even happens, but our children or our children's children, etc., might still be alive and they will have to live on a crowded earth and there will be less space for everything. maybe movie theaters will be knocked down to make houses for the overpopulated earth and many other fun places will have to go to make room for people.so remember people, use protection!!!! unless you are married and you want to have kids and you have all the things neccecary to take care of them, but if you don't have anything to support a child, then don't have unprotected sex! ever! unless you are married and...never mind, you read it already and i don't want to repeat myself again, but i do want to remid you of this, NEVER HAVE UNPROTECTED SEX!

The mass of the earth is increasing, but not\nby very much... the only way mass could leave\nthe earth is for example by rockets that are\nsent out into space (like the Voyager missions,\nwhich are on a no-return trajectory).  The\nway mass is added to the earth is meteorites\nwhich fall from time to time, but are rarely\nlarge enough to make a significant impact\n(although the one that fell creating Hudson's\nBay millions of years ago, for example, would\nhave definitely been measurable!)

Yes, and other countries should follow their example.  There are already too many people on this planet and we need to take action on population growth.

I have no doubt about the fact that the planet is warming up. But it has warmed up and cooled down throughout the history of the planet. It even did this before humans were around. Who was to blame for it then? Nature, same as today. More greenhouse gases are released by natural means (without human involvement) each year than what humans have contributed over the last 10 years.

Earth gains about 40,000 tons of mass each year from infalling cometary debris and meteorites.\n\nGod should be spelled B-I-G B-A-N-G\nPBrax@netscape.com

Projections have the world population hitting six billion sometime around the middle of next year. Beyond that, it's hard to give you an exact answer. We can tell you that there are approximately 25 more people in the world than there were when you started reading this paragraph. That's because current research indicates that about five people are born every second, while two people pass away, leaving us with a population rate of three new humans per second.\n\nhere I found this site also... this is better and this can show your 8 year old alot more!  Have fun!\n\nhttp://www.census.gov/population/www/popclockus.html

Yeah, if you think about it, there is really no way to "add" weight to the earth unless it comes from another planet or moon.  Everything on earth at some point was derived from existing matter.  This is a rule of nature.  Matter cannot be created nor destroyed!
