The article discusses 10 water sources around the world that may look beautiful and inviting, but are actually dangerous and potentially deadly. These include:
1. Blood Waterfall in Antarctica, which gets its red color from high levels of iron oxide.
2. Blue Lagoon in Buxton, which has a pH level of 11.3 due to high levels of calcium and is toxic to humans.
3. Lake Kivu, which has a high concentration of methane and carbon dioxide that can cause explosions.
4. Queen's Bath in Hawaii, which is prone to strong waves and currents that can sweep people away.
5. Mammoth Lakes in California, which has a high level of carbon dioxide emissions from a nearby volcano.
6. Citarum River in Indonesia, which is heavily polluted with trash and toxic chemicals.
7. The Strid in Yorkshire, England, which has a deep abyss with fast-flowing water that can be deadly.
8. Potomac River in the US, which has strong currents and is home to bull sharks and other dangerous animals.
9. Gafsa Lake in Tunisia, which has high levels of phosphate and radioactive residue that can cause cancer.
10. Rio Tinto River in Spain, which has been polluted by mining activities and has a high level of acidity.
These water sources may look beautiful, but they can be deadly, and it's essential to exercise caution and respect when approaching them.
Here are the key facts extracted from the text:
1. Blood Waterfall is located in Antarctica.
2. The waterfall's red color is due to a high amount of iron in the water.
3. When the iron is exposed to oxygen, it reacts and changes color to red.
4. The water under the ice at Blood Waterfall cannot freeze completely due to its high salt concentration.
5. Blue Lagoon, Buxton, is a turquoise-colored lake surrounded by high hills.
6. The lake's water is alkaline, with a pH of around 11.3, making it highly toxic.
7. The lake's water contains suspended calcium mineral dust, which gives it its bright color.
8. The lake's bottom is filled with trash, old car parts, and animal carcasses.
9. The local government dyed the lake water black to deter people from approaching it.
10. Lake Kivu is one of the largest and deepest lakes in the world.
11. The lake has a high concentration of methane and carbon dioxide at its bottom.
12. The gases in the lake can cause an explosion, affecting the lives of over 2 million people in the surrounding area.
13. The governments of the Republic of Congo and Rwanda are working to extract methane gas from the lake to reduce the risk of explosion.
14. Queen's Bath, located on the island of Kaua'i, Hawaii, is a natural bathing pool surrounded by cliffs.
15. The pool is prone to fierce waves during the months of October to May, which can sweep people away.
16. Mammoth Lakes, California, is a town with many recreational activities, but it also has a volcano that produces hazardous gases.
17. The volcano's gases can cause trees to wither and die, and can also be hazardous to humans.
18. Citarum River in Indonesia is heavily polluted with over 20,000 tons of trash, including non-degradable waste and heavy metals.
19. The pollution has caused the fishery to disappear, and the river is now used for scrap buying.
20. The Asian Development Bank approved over 15.5 billion VND to clean the river in 2008.
21. The Strid, a stream in Yorkshire, England, has a rock crevice with fast-flowing water that can be deadly to those who fall in.
22. The stream's water flows faster beneath the surface than at the surface, making it difficult to swim.
23. The government has posted warning signs to prohibit swimming or jumping into the stream.
24. Potomac River in the Central United States is home to white-eyed bull sharks and has fast-flowing water that can suck people underwater.
25. The riverbanks are also home to poisonous snakes, Indiana bats, and Bold Jumper spiders.
26. Gafsa Lake in the desert has high levels of phosphate and radioactive residue in its water, making it hazardous to humans.
27. The lake's water color changes to turquoise when the fresh water flow stops, indicating a higher risk of impurities.
28. Rio Tinto River in Spain has a high concentration of heavy metals due to centuries of mining in the area.
29. The river's water is acidic, with a pH of 1.7-2.5, making it hazardous to living organisms.
30. Pitch Lake in Trinidad and Tobago is a lake filled with asphalt, with no water present.
31. The lake also contains methane gas, making it a unique and hazardous destination.
32. The lake was formed thousands of years ago due to a converging fault line in the earth's crust.
