What is the biggest problem in the world?

Global warming.... It is a long term problem that is not going away, it affects the whole planet and all forms of life, most of the other problems mentioned above affect mainly the selfish human populous.\n\nWhat can you do?....\n\nStop buying products with palm oil is a good start (most rain forest is cleared for palm oil plantations)\n\nTurn off the lights you are not using\n\nDon't leave your PC on all day\n\nDon't leave things on standby (almost the same as leaving a light on)\n\nTry not to use your car quite so much\n\nSome informative and useful sites\n\nhttp://www.mec.ca/Apps/ecoCalc/ecoCalc.jsp;jsessionid=G1TlbhpQxHXzQ0wym1V5DcwxpwC1SGG7QvGYYR1XMsfSJJLk8qhK!-790721544?page=ecofootprint&FOLDER%3C%3Efolder_id=2534374302881659&bmUID=1144345509405\nhttp://www.earthday.net/Footprint/index.asp\nhttp://resources.yesican-science.ca/energy_flow/energy_menu.html\nhttp://www.footprintbc.com/

It has the potential to fix a lot of problems. Maybe we can stop worrying about fighting that battle and work on healing the continent/country(at that point). It would help to better the world as a whole and allow many new points of view and plans to better the world come to fruition.

Are you asking, "What variety of health problems effect the modern world on a global scale"? If so I'd cite:\n\n- AIDS\n- Bird Flu\n- West Nile\n- Lack of sanitation in the "second world"\n- Lack of adequate nutrition in the "third world"\n- Obesity

i think the biggest threat in america is stupidity.  there are just so many stupid people in this country and its whats causing so many problems.  if people actually cared more about their lives and their education, instead of trying to be cool and popular and not care about anything but marrying into money and stop being lazy and actually TRY to learn something, our country would be MUCH better off.

I'm pretty afraid.  I don't know where we're headed economically, politically, environmentally, anything...and I'm not even sure what will be the biggest problem first.  For instance, it's relatively clear that climate change will be an issue, but when?  And is it even possible at this point for us to turn some of these things around?

For me mine would be the (WORLD)...how to get along...stop the killing, racism, and the war.

Sad to say, but I think America is probably one of the greatest problems this world is facing.\n\nIt's not terrorists.. jeeze krapoleze. They've been around forever, it's only America that has stirred them up with our corporate greed and the Bush Administration.\n\nTerrorists.. they are the ones with the nasty nuclear bombs. right? I don't think most Americans know how many nuclear warheads we ourselves have!!!\n\nWe have over 5,000 ACTIVE nuclear warheads in our possession! almost 10,000 in total. WTF do we need with 10,000 nuclear warheads?!?! freaking good grief. In the past three years, we've killed thousands.. whoze the terrorists? I'm losing track. I support the troops, but I don't support the decision maker.\n\nAside from the war crud.. we have the power (resources) to be the most powerful nation around. But we use it in what I feel are the wrong ways. I mean come on, we're taxed beyond belief and yet our school systems, public transportation, healthcare is freaking out of control, good freaking bloody hail! We spend more money and resources on military than all other countries put together. And where do you think all that money is going? Who's pocketing the profits? Big freaking corporations. If we just took 5% of the military spending and put it into the other issues, we could be finding cures and helping those that need it. We have starving people, homeless people right here. 5% cut in military is not going to stop our country from defending ourselves from attacks and whatnot.\n\nI think being proud to be an American is more difficult for every American to say anymore. We consume a gigantic percentage of the worlds resources as compared to our population.  That's sickening in itself. I watch the learning channel where they rip up perfectly good household kitchens - throw it in the dump - and make new kitchens just because it's more visually appealing. We're so dam spoiled rotten it's sick. We buy groceries and throw half of it away when it spoils. We build mansions for one person to live in. We buy brand new appliances because the corporations make it too expensive to fix the old ones. Things last 5 years instead of 50. How long do you think things would last if we required the corporations to take back the appliances and cars after their life cycle was up to recycle the goods? SUVs are used primarily for moving one person to and from work and everywhere else. The Hummer? \n\nMoney / corporate greed have become the American way - that's the primary problem with respect to everything. And most of it revolves around our judicial system. When you award millions of dollars to one person for a spilt cup of coffee, it's screwed.\n\nI asked a person who moved here.. does she like it better here or from the third world developing nation she came from.. she had to think for quite a while. That's pathetic. We get the same score as a third world nation? When I ask why... her response was "here it's nuts. all the rules and regulations and people winning crazy lawsuits.. at least in my country you can live your life."\n\nI don't think America is seeing the changes we're going through and what we could be doing to the entire world. We're just going through life.. day by day.. the American throw-away society. Throwing away our freedoms, throwing away our rights, and throwing away our future so we can live the now.

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.

Humans are their biggest challenge... dealing w/ our nets, pollution and global warming for example.

I'd say one of the most pressing issues would include the US occupation of Iraq.  I'm sure you can find lots of historical data and speculations about the future conclusion.

Your question is so broad you are asking for\nan answer that could earn someone a Master's degree!\n\nI would say that resources is the major problem in these areas.  Lack of water, food, shelter, education, housing, medicine, doctors, ...
