Necrosis and snake bites

What type of snakes cause these bites?

Death adders and Gaboon vipers are most commonly known for these types of wounds. Death adders live in Australia, whereas Gaboon vipers are found in Africa in the rainforest areas. Other snakes that also cause necrosis are:

What is Necrosis?

Necrosis is when premature cells or tissue dies due to a Snake bite, other injury, lack of blood flow, or bacteral infection. bacteral infections that cause this are mostly Clostridium Perfringens, Streptococcus pyogenes, and Staphylococcus aureus. The science behind Necrosis is pretty interesting, for instance toxic production: whenever bacteria such as the ones listed enters the body, they release toxins and enzymes that basically break down the tissue, for example Streptococcus pyogenes produces exotoxins that cause cell damage, while Clostridium perfringens produces enzymes like collagenase and hyaluronidase, which weaken the tissue (like collagen and hyaluronic acid), allowing the bacteria to spread way faster and easily.

there is also Tissue death, when infection gets more and more severe and the tissue starts to die because of the lack of oxygen (also called hypoxia), the tissue becomes "necrotic", which means it starts to rot. Think of it as if you tie a rubberband too tightly on your wrist and leave it there for several hours/days, oxygen isn't able to reach the rest of your hand therefore the those cells start to die.

Probability Theory

Introduction

If a person were to randomly teleport anywhere on Earth, several factors would determine their death. These include whether they land on water or land, which continent they appear on, and their chances of survival if dropped from a random height. This essay will analyze these probabilities and assess the likelihood of survival given the conditions of such an event.

Probability of Landing on Water vs. Land

Earth is covered by approximately 71% water and 29% land. This means that the probability of randomly teleporting into a body of water is 71%, while the probability of landing on solid ground is 29%. If the teleportation includes oceans, seas, rivers, and lakes, then the vast majority of water landings will occur in the open ocean. Large lakes and rivers make up only a small percentage of the total water surface, meaning the probability of landing in a large body of inland water (rather than the ocean) is relatively low.

Probability of Landing on Each Continent

Continent Surface Area (million km²) Probability of Landing
Asia 44.58 29.8%
Africa 30.37 20.4%
North America 24.71 16.6%
South America 17.84 12.0%
Antarctica 14.2 9.5%
Europe 10.18 6.8%
Australia 8.56 5.7%

Probability of Landing in a Cave

Since caves cover only a fraction of Earth's land surface, the probability of teleporting directly into a cave is much lower. Estimates suggest that about 10% of land has significant cave systems. Therefore, the probability of randomly appearing in a cave is: 0.29 x 0.10 = 2.9% This means there is a 2.9% chance of landing in a cave upon teleportation.

Survival Chances When Teleporting to Land

One of the greatest dangers of random teleportation is the height at which a person appears. If the teleportation occurs anywhere between ground level and the stratosphere (~50 km / 164,000 ft), survival becomes a major concern.

Given these conditions, the estimated survival rate for falls onto land is only 2% (0.02 probability). Since there is a 29% chance of landing on land, the combined probability of landing on land and surviving is: 0.29 x 0.02 = 0.58%

1. North Sentinel Island, India

North Sentinel Island is one of the most isolated places on Earth, home to the indigenous Sentinelese people, who actively reject contact with outsiders. The tribe has lived on the island for thousands of years, maintaining their ancient way of life, and their hostility toward intruders is well-documented. Anyone attempting to approach the island is met with spears and arrows, making it one of the most dangerous islands in the world. The Indian government has recognized the island’s risk and has declared it illegal to visit. The dangers aren't just from the tribespeople, but also from potential diseases to which the Sentinelese have no immunity. The island’s protection helps preserve the tribe's autonomy and shields them from modern threats, but it also keeps their way of life untarnished by the outside world.

2. Ilha da Queimada Grande (Snake Island), Brazil

Ilha da Queimada Grande, or Snake Island, is located off the coast of Brazil and is notorious for its high population of golden lancehead vipers, one of the most venomous snake species in the world. The island is home to around one snake per square meter, making it incredibly dangerous to even step onto its shores. The snakes are highly aggressive, and their venom can cause death within hours if bitten. Because of the extreme risks, the Brazilian government has banned visitors from setting foot on the island. Even with specialized equipment, the venomous creatures make it almost impossible to safely navigate the island. Despite its natural beauty, Snake Island is considered one of the most hazardous places to visit due to the deadly reptiles that call it home.

3. Gruinard Island, Scotland

Gruinard Island, located off the coast of Scotland, is infamous for its dark history as a site for biological warfare testing during World War II. The British government tested anthrax on the island, contaminating the soil and making it unsafe for habitation for decades. In 1981, the island was declared free of anthrax, but it still carries a lingering risk, with traces of the disease potentially remaining in the soil. The island was isolated for many years due to its toxic contamination, and though there are efforts to restore the land, its reputation as a site of biohazardous experiments has made it off-limits to the public. Gruinard Island is a somber reminder of the dangers of biological weapons and the long-lasting effects they can have on the environment. Visitors, even today, are urged to stay away from the island to avoid the potential health risks.

4. Farallon Islands, USA

The Farallon Islands, located off the coast of San Francisco, are considered one of the most dangerous islands due to their proximity to shark-infested waters and the presence of hazardous materials. The islands are home to a vast colony of sea birds and marine life, but they also house dangerous creatures, including great white sharks. Additionally, the islands were used as a dumping ground for radioactive waste in the past, which has contributed to their dangerous reputation. Today, the Farallon Islands are largely off-limits to the public due to these risks and the fragile wildlife ecosystems. The surrounding waters are also treacherous, with rough currents making navigation difficult. Despite the natural beauty of the islands, the combination of toxic waste, dangerous predators, and harsh conditions makes them a perilous destination.

5. Fraser Island, Australia

Fraser Island, located off the coast of Queensland, Australia, is famous for its diverse ecosystems, including rainforests, sand dunes, and beaches. However, it is also home to a variety of dangerous wildlife, including the dingo, a wild dog that is known to attack humans. The island is also home to venomous jellyfish, known as box jellyfish, which can be deadly if stung. The combination of dangerous animals, hazardous terrain, and unpredictable weather conditions makes Fraser Island a risky place to explore. While the island is a UNESCO World Heritage site, visitors are warned to take safety precautions and be aware of the island's potential dangers. The wild environment of Fraser Island requires careful preparation, as the island’s beauty can quickly turn dangerous without the proper precautions.

6. Rockall, United Kingdom

Rockall is a small, remote granite islet in the North Atlantic, known for its treacherous weather conditions and rough seas. The islet is uninhabitable due to its size and the dangerous environment surrounding it. The weather is unpredictable, and the strong ocean currents make the surrounding waters dangerous to navigate. The islet has no fresh water or natural resources, making it an unappealing destination for humans. Despite its desolation, Rockall is occasionally visited by adventurers and researchers, but the risks involved make it a perilous journey. The island’s isolation and hazardous conditions ensure that it remains one of the most dangerous places on Earth.
