The United States mined Baker and Howland Islands for which natural resource?

Explanation:
Guano—bird droppings rich in phosphate—was a highly valued fertilizer in the 19th century. Islands with large seabird colonies, like Baker and Howland, accumulated thick guano deposits, making them attractive to harvest. The United States even passed the Guano Islands Act in 1856, allowing claims on uninhabited islands with guano deposits, which led to mining on these atolls. The actual extraction focused on the guano deposits themselves, supplying phosphate for fertilizer. Oil and coal aren’t associated with these islands, and while phosphate is a component of guano, the resource mined was the guano itself.
