Human health \n\nEating clams, mussels, oysters or scallops contaminated by red tide can cause severe illness and even death to humans. Federal regulations now require toxin monitoring programs that are implemented during red tide outbreaks. While some illnesses related to shellfish consumption occur, the highly cautionary regulations have been quite effective. \n\nAerosols from red tides can produce respiratory ailments. However, no studies have been done to determine if there are long-term consequences of inhaling potent neurotoxins from algae. Also, it is difficult to assess long-term effects of acute exposure among tourists who leave the area. \n===============================================\n\nPlease see a doctor right away! In the mean time, don't eat any sea creatures and protect yourself from common colds. The treatment that I found includes infussion of antibiotics and being in an oxygen tank.\n\nGood luck!

My sister owns one. At first, I thought it would be horrible, but the level of salt is so low, you can hardly taste it. And she says it saves them a bundle on chemicals. And you don't tend to have the chemical smell of clorine either.

bats are beneficial - they kill mosquitoes and other insects so I would suggest you encourage them rather than discourage them - unless of course they are inside....\nI dont know the answer in that case I think everybody is mostly guessing here - would think something that messes up their sonar would be a problem for them or leaving lights on

I guess Yahoo Answers has asterisked-out your word, but if you're asking about m-a-s-t-u-r-bation, no, it is not harmful. In fact, it is beneficial because by so doing, you learn about your own sexuality, and when you are ready for a sexual relationship with another person, you will be in a better position. Good luck, and have fun with yourself! ;)

Yes, but they are probably too weak to do any harm.\n\nA strong whirlpool needs a lot of water with considerable temperature differential to feed it so the hurtful ones won't occur in shallow water.  Of course, there are seashores with considerable drop-offs near shore so just watch out for them.

Not if you pull them.  However as this is in Diet maybe you mean mussels???

use a clam rake instead of a gun.  You don't have to get the expensive one at the tackle shop just get a wide toothed one at the hardware store.  you will pull in a lot more.  I like to put them in a bucket with clean water to let them work on spitting out the sand before cooking.  Don't mind the mud go barefooted it makes it easier to clean up after wards.  May sure to get a shellfish license and follow the rules and regs.  It is a pretty good fine depending on which coast your on.

i do not recommend it. essentially you have both good and bad bacteria in your vagina. when you douche, it kills all the bacteria. But the good bacteria eats the bad bacteria. If you kill it all, the bad bacteria will overrun you with nothing to counter it and will cause a yeast infection. i really don't understand how anyone uses them. they always caused me problems and i had no idea until someone told me this.

not at all , its very healthy!   the only time you have to limit  your  ingestion of seafood is when you are pregnant , due to the possibility of mercury, but other than that , enjoy!

I've only found one reference to this behavior, and the original publication is in Russian. Orcas are social mammals and it would take extremely stressful circumstances for cannibalism to occur.

Erm... not a whole lot. I don't think they're generally all that smart.  Sorry, I know that's not what you meant...\n\nSome species of molluscs are being studied in a laboratory at LSU because they apparently have some interesting defense against a certain state of V. vulificus (which I assume is some sort of paracite, although I don't know for sure).  For more information see http://www.upei.ca/cai/mollusc-june05.htm\n\nThere was also a new antibiotic was isolated from the common do whelk mollusc at some point (the article doesn't actually give a date).  A little more information at http://media.uow.edu.au/archive/oldbytes10/extra/extra9.htm\n\nThere are also several species of molluscs that are posionous (I think most produce neurotoxins), and are studied as the cause of rather than the cure for conditions.\n\nAnd for entertainment purposes: medical advances *for* mulluscs\nhttp://www.upei.ca/cai/mollusc-june05.htm\n\nOK kunwarrarra, you may have won the bird question (taxonomy rather arbitrary anyway if you ask me), but I beat you here. :)

well i believe that its not harmful or produce any decease but it can make a person addicted to it. that is harmful in the way the person gets addicted to it, lets say he prefers masturbation then normal sex. its a hard situation for those who do it, they don't feel satisfaction during sex and then in the end masturbate because they are used to it.

of course not. The lobster market is one of the fastest growing markets.  Yet, it is kept in check by regulations. Only so many can be caught and it in no way hurts the population. Actually helps it. Less lobsters on the ocean bottom means healthier lobster. Not having to compete for food.

Take live snails to the mall, blindfold passersby, and feed them snails.  Hypothesis, snails taste gross. Prove or disprove. Discuss.  Alternate hypothesis, life gives life.  If snails ate humans, then humans would kill snails.  Since they don't eat humans, there is no good rational for killing them.  Unless you have too much salt and are bored :)

harmful: parasitism\n\nit feeds off plants, no benefit to plant
