Because they eat it.
The Guano Island Act of 1856 allowed the United States to claim unclaimed islands containing guano deposits for the purpose of mining the valuable bird droppings. This act aimed to secure a domestic supply of guano, which was used as a fertilizer and was in high demand during the 19th century.
There is no actual "Guano Island". There is a Guano Island Act, which is a federal legislation passed by the US Congress on 18 August 1856. It enables US citizens to take possession of islands containing guano deposits. Guano is the droppings of bats, seabirds, and seals. It is a highly prized fertilizer.
The Batu caves were being excavated for guano by Chinese settlers in the 1860's. However they were considered officially discovered by American naturalist William Hornaday in 1878.
Guana is word in the Spanish language. It is used to describe the feces and urine of certain animals such as bats that live in caves, seabirds and seals.
I assume you mean caves well decorated with stalagmites etc. They are in most limestone caving areas but if you want to visit them either take up caving properly - for both your safety and to learn to protect the caves you visit - or visit show-caves.
Phosphorous may be found in the sea, and in bones. As a consequence of it being in the sea, it my also be found in some limestone deposits, and in seabird guano.
Be reassured, there is no guano in Oreos.
yes it's poop
Bat droppings, also known as guano, are used as a natural fertilizer due to their high nutrient content, including nitrogen, phosphorus, and potassium. They can improve soil quality and promote plant growth. Additionally, guano has been historically used as a component in some traditional medicines and in the production of gunpowder.
Guano is bat faeces and they are NOT dangerous.
Guano Apes was created in 1994.
That is the correct spelling of "guano" (bird droppings used as fertilizer).
