Was there any bacteriogical bomb use in Africa? Why they cannot grow anything to feed themselves?

Deforestation led to poor soil quality led to the formation of deserts. Don't be an idiot.

For pure profits...an example being...Africa produces enough food to feed its self...but exports are essential to the economy so they sell there food to rich countries and have their own people suffer.

theres a whole bunch of conspiracy theorys on this if you search around.  I found this one article though that was kind of interesting http://archives.cnn.com/2002/WEATHER/05/27/bugs.weather/index.html\n\nif we can use microbes to make medicine why not control the weather with them... really both concepts are pretty crazy but the medicine one is already done.

Small microorganisms (bacteria or protists) that are unable to survive outside a host cell. This may be due to their cellular membranes/walls that are very permeable and do not allow them to maintain homeostasis (internal balance). Sometimes they require substances that they cannot produce themselves and must obtain from the host's metabolism.\nExamples: Legionella pneumophila (bacteria causing pneumonia)\nMycobacterium leprae (the bacteria causing leprosy)\nPlasmodium (protist that causes malaria)

if i remeber correctly archaebacteria are the ones that live when none should. like near volcanic vents on the ocean floor and in the subzero of antartica and the like. so if one can be found to survive in a toxic area they can be used to clean up a place. thats the only thing i can think of in economic terms.

There is an agricultural economics scientist G. Ntoukam in Africa doing research on cow peas.  I also believe he co-authored a paper on economic impact of insects! See link below

Those answsers are wrong. It is a bacteria that lives on an aphid. Here is the link to prove it:\n\nhttp://phylogenomics.blogspot.com/2006/10/worlds-smallest-genome-of-cellular.html

>>>>>(IT IS NOT HOMEWORK! i am competing with a friend for the >>>>> best example)\n\nAnd cheating by asking strangers on the internet. I like the way you think.\n\nThe most extreme example of bacterial endosymbiosis amongst mammals is without a doubt the presence of mitochondria. You might not relaise it but mitochondria are stable line bacterial endosymbionts, complete with there own genetic structure. It's hard to top that.\n\nAfter that probably comes the entire rumen structure of ruminants. Its incredibly cmmplicated, but basically the stomach of cows and sheep is one massive bacterial fermentor. The cow eats grass but is totally unable to digest it. Instead it grinds the grass up fine and swallow sit to wet it. It leave sit in the stomach to fermenta while then brings it up to shew again after the bacteria have softened it. The food then goes back down for even more fermentation in the other three chambers of the stomach. To add to the elegance of this system cows don't just excrete their urea through their kidneys like other mammals. Urea is  a waste in mammals and is poisonous, but it is also a good fertiliser. Ruminants excrete their urea through their salivary glands. It then passes into the stomach and what was a poison to the cow becomes fertiliser for the bacetria, who convert the waste urea into protein that the cow can use. As a reuslt ruminants are the only mammals in the world tht can survive with no protein input intheir deit at all. Which explains why they have been so extraordinarily successful at surviving in harsh and low nutrient environments.\n\nLast comes the biosynthesis of vitamins. Mammals can't   make their own vitamins, they normally need to take it in on the food. However numerous mammals species from dogs to horses are able to harvest those vitamins from bacteria that grow in their guts. So although a dog lives on a diet that is horrendously deficient in 3 or four vitamins it never gets ill or needs to take vitamin tablets. Which is pretty clever.

Yes, the scenerio depicted in "Mad Max Beyond Thunderdome" was true in theory.  Any organic material like food or poop can be used to generate methane.\n\nIf given sufficient oxygen, bacteria will oxidize hydorcarbons like sugars, proteins and fats to carbon dioxide and water.  But if there is not enough oxygen (like under the mud of a swamp, in a landfill, or a septic tank) then the bacteria power themselves off the "food" and produce methane.\n\nCan you heat your house off your septic tank.  No.  You might make 1% of your energy needs and it wouldn't be worth the bother.\n\nCan anyone make useful energy by generating methane from waste?  Yes.  A lot of landfills extract methane and run engines on it and produce eletricity.  Often they are forced to in order to reduce methane emisssions or explosive hazards but they do produce tens or hundred of kilowatts at a large landfill.\n\nCow poop to methane?  The only place cows are concentrated are at a feedlot.  Their focus is on making skinny range cattle into fattened cattle for slaughter in a few weeks.  They want to get rid of the manure quickly and devote their attention to the core business.  Energy prices would have to rise a lot to interest them in the process.\n\nHog, chicken, turkey and other CAFOs (concentrated Animal Feeding Operations) are denser, stinkier sources of poop.  The winning play there might be that sequestering away the manure to make methane also cuts down the smell A LOT and that keeps the neighbors happy.  But until enough states and countries ban current-practice CAFOs, most will go with what they've always done, IMO.\n\n-David\nKenai, Alaska

No.  It started in Africa.  I mean, anything is possible, but why the government would want to play around with diseases is beyond me.  Realistically, no.

There is an optimal evirnment for bacteria growth. Honney is too sugary (too much food) and pickels have too much acid in the liquid. This does not mean that they will never grow though.

The reason for this is the history of mankind for the last 10thousand years.\n\nFarming started in the fertile crescent and branched off from there in an east west direction.  For the same crop to be grown at a different lattitude it had to go north and south, at a substantially slower rate, because the plant would have to adjust to the change in sunlight.\n\nTo go east and west from the fertile crescent to france or to china is didn't have to change that much, the plants.\n\nThere were also animals in europe and asia the could be domesticated, like cows and pigs, the animals in africa are zebras or tigers, and can't be domesticated. Modern attempts in other places besides africa haven't proven successful.\n\nSo the farming only hit egypt originally, and maybe spread to ethiopia, but it didn't last to modern times because of the culture of hunter gather that was dominant throughout africa spread and didn't choose to continue farming.\n\nNow the Europeans came in the 1700s and 1800s with guns and germs, and eliminated some of the population and divided the remaining populations,\nyou've seen hutu and tootisy and know that this has to do with an artifical division.\n\n\nSo theres no agricultural base, which is prerequisite to capitalism, which is prerequisite to a nation having wealth.\n\nInstead the continent seems content on the genocidal whims of whoever has the guns left over by the europeans.\n\nGod has nothing to do with it, and anyone who says so, I really question their intelligence.

Bascially they killed themselves as they could not live in our world as it is . They were not prepared for the new diseases,bacterias, etc that had come into being since they began there trek...\nApparently they gave the human race more credit than they deserved. Just look at what we put into our systems on a daily basis, even just walking outdoors can be unhealthy for us, imagine someone who did not have any immune system to speak of. How quick would they die?\n Great movie by the way!!!

There  ate tons of mediums commercially available to culture bacteria, they come in the from of liquid (broth) or  solid media (agar). They can be non selective, selective or to differentiate.\nBut is you are looking for a household material you can use  baby food or gelatin. It depends on what you want to cultivate.\n For example if you use the baby food there will also grow fungi and other microorganism.

I made several of these in Africa attempting to make something simple that the people could use.. the dwindling supply of wood in the Sahel regions is very very serious and they have to come up with something else other than using wood... so. the solar oven??\n\nA solar cooker or solar oven is a way of harnessing the sun's power to cook food. A metal box forms the simplest solar cooker. A set of large mirrors or a large Fresnel lens to focus sunlight to a single point may also be added. On a sunny day a black baking tray or cooking pot can convert hundreds of watts of light into heat, in addition to any infra-red. Temperatures in a typical oven can reach 200 °C (400 °F).

You cant really guarantee it, but I am sure it can be argued that it could be a solution. This example that I am gonna give is gonna be really vague, but there could be a way to speed up the growth rate of gen modified food and therefore creating more food to eliminate hunger and starvation. It could also be made to resist certain unfavourable conditions that could make plants resist extreme temperatures. I heard of [i think] strawberry being grown in warmer climates becuase they are gen. modified (Their preffered climate is in colder areas). I cant remember much about it tho.. I got this from my bio teacher.... it could be a possibility.

Check out this very straighforward website:\nhttp://en.wikipedia.org/wiki/Francesco_Redi\n\n"Pasteur boiled meat broth in a flask, heated the neck of the flask in a flame until it became pliable, and bent it into the shape of an S. Air could enter the flask, but airborne microorganisms could not - they would settle by gravity in the neck. As Pasteur had expected, no microorganisms grew. When Pasteur tilted the flask so that the broth reached the lowest point in the neck, where any airborne particles would have settled, the broth rapidly became cloudy with life." \nHere's a picture of this setup:http://en.wikipedia.org/wiki/Image:Ballon.gif\nBoth experiments disproved spontaneous generation (abiogenesis); Redi disproved it in larger organisms, and Pasteur disproved it in microorganisms.
