le: What You Should Know About Lesser-Known Facts There are many lesser-known facts out there that can be fascinating and even mind-blowing. In this article, we explore some of these cold, hard facts that might change the way you perceive the world.
1. Venomous vs Poisonous Did you know that there is a difference between "venomous" and "poisonous"? Venomous organisms inject toxins into their prey using specialized delivery mechanisms like fangs, stingers or spines, while poisonous organisms have toxins that are usually ingested or absorbed through the skin. This means that a venomous animal is harmful when it bites or stings you, while a poisonous one is harmful when you touch, eat or breathe it in.
2. The largest living organism on the planet is a fungus The world's largest living organism is not a blue whale or a giant redwood tree, but a fungus called Armillaria ostoyae. This underground creature covers over 2,200 acres in the Malheur National Forest in Oregon, USA. It is believed to be over 2,500 years old and weighs an estimated 605 tons.
3. There is a country that's smaller than New York's Central Park The Principality of Monaco, bordering France's Mediterranean coast, is the second smallest country (after the Vatican City) in the world, with an area of only 0.78 square miles or
2.02 square kilometers. For comparison, New York's Central Park is over twice its size at
1.34 square miles.
4. Human saliva can heal wounds It might sound gross, but human saliva has properties that can promote wound healing. Saliva contains antibacterial agents like lysozyme that can fight off bacteria and enzymes like growth factors that can stimulate tissue regeneration. However, it is not recommended to apply saliva directly to open wounds as it may also harbor harmful germs.
5. The Sun is actually white We often depict the Sun as a bright yellow or orange ball, but in reality, it is white. The reason we see it as yellow or orange is because only the longer wavelengths of light (red, orange, yellow) are able to penetrate the Earth's atmosphere and reach our eyes, while the shorter wavelengths (blue, violet) get scattered away. However, if you observe the Sun from space or through a special filter, it appears as a blazing white star. These are just some of the lesser-known facts that can make you see things differently. Keep an open mind and who knows what you might discover next!
