How Many Types of Plastics Exist and Why?

Plastics are one of humanities most critical inventions, and one of its most dangerous and fierce threats to public and health and wildlife. Critical for transportation, medicine, and food safety its overuse has beared its very negative aspect. One that is specially harsh on Oceans, that now continuously move tons of waste plastics and with it millions of animals die because these things are outside their natural habitat and have not evolved to suvive them.

Plastics are classified according to its layers of plastic and special properties according to market demand.

  1. Polyethylene Terephthalate: Also called PET, it is the common plastic used for household activities. It is the common plastic to be recycled in most countries.
  2. High-Density Polyethylene ( HDPE) is a plastic known to not transmit any chemicals in the food it contains. It is recommended not to use any container of this type of plastic that originally did not contain food to store food.
  3. Polyvinyl Chloride: Also named PVC is the plastic used for tubes and pipes. It can be very harmful if ingested so it is preferable to avoid contact with food.
  4. Low-Density Polyethylene: Is a plastic sometimes recycled. Some of its characteristics are the durability and flexibility. Plastic grocery bags are made from this type of plastic.
  5. Polypropylene: PP is a strong and durable plastic resistant to high temperatures. Plastic bottle caps, lunch boxes and yogurt pots are made from this type of plastic.
  6. Polystyrene: A common but difficult to recycle plastics. Plastic cups and food boxes are made from this type of plastic.
  7. Code 7: Polycarbonate and polylactide are included in this category because of the difficulty in recycling them. Baby bottles, CD´s and medical containers are made of this Code 7 plastics.

What are The Most Expensive Liquids In The World?

The most expensive liquids in the world! From LSD to channel n°5, you better have some serious cash money to buy the things on this top list, because they are crazy expensive! Venoms from Scorpion or the precious horseshoe crab blood.

Scorpion Venom
The notorious Scorpion roams the desert sands and is well known for its dangerous bite. Though There are close to 2,000 scorpion species each species has specialized venom to suit its environment. Not many people though know how lucrative the venom can be. At close to $10,000 per liter, it is one of the most expensive liquids on the planet. This is due to the obvious dangers of acquiring the venom, the rarity of the specimens and the medical uses of parts of the venom. In fact, Some of the toxins are immunosuppressants which are chemicals that suppress the immune system. These can help in diseases where the immune system is not functioning as it should and in the right doses, Scorpion venom toxins can help treat diseases such as multiple sclerosis. Interestingly scorpions are not prone to using their venom and would much rather catch prey with their claws due to the difficulty in creating it. However, They will use the venom to escape larger predators and various situations they cannot flee from. Though often painful, scorpion bites are rarely fatal and many antivenoms have been made for the various types of scorpions in the United States alone.

GHB
Known scientifically as Gamma Hydroxybutyric Acid, and non-scientifically as the ´Date Rape drug, GHB is a very interesting drug. As a drug, it is a depressant and therefore dampens the central nervous system. At $660 per liter, legitimate uses for GHB include treatment for narcolepsy, alcoholism, and cataplexy. It is used illegitimately and most famously as a drug that especially when mixed with alcohol can cause rapid intoxication and sedation. Side-effects can even include memory loss after use. The rapid intoxication effects are sometimes used by teenagers for a powerful high, and users describe it having a salty or soapy taste.

Mercury
This amazing liquid metal is also known as quicksilver and before its toxicity became widely feared, it was used in many devices around the world. The most popular were thermometers, thanks to its quick expansion during temperature changes. In fact, some historians believe that The first emperor of China died after exposure to Mercury that was ironically supposed to give him eternal life. To ancient alchemists, mercury was a pure state from which other metals could be created by simply adding sulfur. Today, however, mercury poisoning is a well-documented occurrence and is actively avoided at all costs. Still, as an element, Mercury is particularly rare and exists only in small amounts within the Earth’s crust. It is still used today in some kinds of electrical switches and some kinds of blood pressure monitors. The price? Around $900 per liter.

Horseshoe Crab Blood
Through our human blood can look blue in our veins, that is only because our eyes see the blue light that has a different wavelength than red. Our blood is red in part thanks to the segment of our blood called hemoglobin, which is iron-rich and helps distribute oxygen to the cells. The living fossils that are Horseshoe Crabs don’t have this. Instead, they have something called Hemocyanin, which is copper-rich and makes their blood appear blue. This blue blood is highly valued at close to $16,000 per liter and has led to the creation of many harvesting farms. Most crabs survive, though Up to 30% may die depending on the harvesting center. The blood is so highly valued as it contains specialized cells which are amazingly powerful at fighting bacteria. They are not only more effective than vaccines but much faster and Have helped horseshoe crabs survive for almost 450 million years. Unfortunately over harvesting is having an effect on crab populations, though vaccines are being developed that may save countless human lives. As we are learning to take the best of other species to improve our own we seem to be leaving some hurt animals in our wake.

LSD
This is the Drug that would become synonymous with the sixties as a whole and the flagship of psychedelics. Also known as acid, LSD can provide vivid visual effects and hallucinations and was a popular recreational drug. A powerful and well-researched substance, It has been used by many pop-culture icons after its invention in 1938. Its mental effects were discovered when it´s creator Swiss chemist, Albert Hoffman accidentally consumed a number of doses by licking his fingers after working with the chemical.
