The answer that best identifies a product made from natural capital is jet fuel.
Jet fuel is derived from crude oil, which is a natural resource, making it a product that can be linked to natural capital. However, since jet fuel is specifically processed from crude oil, it represents a direct conversion of natural capital into a usable product.
While forests, crude oil, and coal are all forms of natural capital, they are not products made from it in the same way that jet fuel is a processed product.
