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!

Chuck Norris\n\nContrary to popular belief, Chuck Norris, not the box jellyfish of northern Australia, is the most venomous creature on earth. Within 3 minutes of being bitten, a human being experiences the following symptoms: fever, blurred vision, beard rash, tightness of the jeans, and the feeling of being repeatedly kicked through a car windshield.

The most dangerous animal, besides man, is the mosquito.  They carry malaria and other diseases that kill 1 million Africans a year.  Bug repellent, mosquito nets and staying away from standing water is probably the best bets in avoiding them.

Urtica dioica (common name stinging nettle)is one of the most nutritious plants around.  Be careful of the irritating hairs which protect the plant from foragers.  I would be surprised if you can find a more nutritious plant than this one in the wild.

The deadliest and most venomous snake is without a doubt the Rhinocerous Viper of Africa. Man, that thing is SOOO colorful! Looks nice, but it is DANGEROUS. Watch out for it next time you visit Africa! \n\nGold is impossible to decompose, by the way.

tetrachlorodibenzoparadioxin (TCDD) also called dioxin. the most harmful known form of dioxin.  It is produced inadvertently during manufacturing processes that use chlorine, such as paper and pulp bleaching. It is also given off by incinerator fumes.  TCDD, an ingredient of Agent Orange, which was linked to health problems in Vietnam veterans and local villagers exposed to it. Chronic exposure is believed to multiply the risk of several cancers, increase the chance of immune system disorders and liver problems.\neffects from high dioxin doses in humans include decreased liver function, an enlarged liver, and slight increase in blood fats, though both effects tend to be mild and short-lived. Dioxin poisoning can also increase the risk of diabetes.

1) Ugliest Plants\n\nNo... Never come across ones and to me all plants are pretty lot...\n\n2) Sickening Plant:\n\nRafflesia (corpse flower/meat flower)  found in Sumatra and Kalimantan (Indonesia), Sabah and Sarawak (East Malaysia).\n\nI see one in Riau (Sumatra)... It can attract flies too.. The flowers smell like rotting meat.\n\nRafflesia is an official state flower of Sabah in Malaysia, as well as for the Surat Thani Province, Thailand.

The worst job I ever had was working in a chemical plant making worm killer for international agricultural use!  The stuff looked like runny peanut butter, smelled horrible & ruined six pairs of work boots in six months!  Needless to say, I got out of there at the first available opportunity!

The most poisonous spider by far in the US is the black widow. This is the only US spider with even a remote chance of killing a human. And yes, it's found in Texas.\n\nThe most poisonous spiders in the world are the Australian funnelweb spiders. There are several species, and usually the Sydney funnelweb is listed as the  most poisonous thoughthatmay be simplybecause it lives near the most people so more people have an opportunity to be bitten.

The poison from the skin of the world's most poisonous known creature-the tiny, 1.5-inch, Golden Poison Frog (Phyllobates terribilis)-kills the monkey.\n\nAn average P. terribilis contains about one milligram of poison, which is enough to kill 10,000 mice-perhaps enough to kill 10 to 20 humans if the poison reaches their bloodstreams.\n\nThis extraordinarily lethal poison (a steroid alkaloid, called batrachotoxin) almost does not occur in nature. We have found this poison only among three poison frogs in Colombia and two poison birds in Papua, New Guinea.\n\nThe yellow frog stores the poison in skin glands, as do most frogs. Due to their poison, frogs taste awful to predators but P. terribilis' poison kills whatever eats it-except for a snake (Liophis epinephelus). This snake is resistant to the frog's poison but not immune.\n\n"We fed one juvenile frog to a snake and the snake showed great distress and was rendered helpless for several hours," says John Daly, chief of the National Health Institute's bioorganic chemistry laboratory.\n\nThe poison frogs are perhaps the only creatures immune to this poison. The poison attacks the sodium channels of the cells. Through the ages, the clever frog has evolved special sodium channels that the poison can not harm.

The Daily Mail in the UK says:\n\nPolonium 210 is one of the most toxic substances known to man, with a particle the size of a speck of dust enough to cause the sort of slow, agonising death suffered by Alexander Litvinenko. \n\nWeight for weight, the rare radioactive isotope is 250billion times more toxic than cyanide, and more than a billion times more radioactive than uranium

My high school chemistry teacher made sure we were all warned about this dangerous chemical.\n\nH20. Water.
