In the 15 and 16 centuries, Brazilian mahogany was an important raw material for making red dyes in the world at that time, mainly produced in Asia, so it was a very rare and expensive material in Europe; During the Renaissance, the demand for expensive textiles (such as velvet) increased greatly, and most of the red dyes needed were transported from the East to Europe in powder form. /kloc-When Portuguese navigators discovered the new continent in the early 6th century, they immediately noticed that there was a country with a large number of Brazilian redwoods, which were mined on a large scale and transported back to Europe. Over time, everyone forgot their original name and called this country Brazil.

Within a few years, because the Portuguese royal family allowed a few businessmen to monopolize the mining and transportation of Brazilian mahogany, the prosperous business situation attracted the envy of other countries, which led to the increasingly serious piracy, smuggling and even piracy activities of Portuguese merchant ships. Overexploitation (it is estimated that about 50 million trees will be cut down in the next two centuries) led to a sharp decline in the number of Brazilian redwoods, so this economic activity eventually collapsed in the18th century. So far, this species has disappeared in most parts of the country and is listed as an endangered species by IUCN. Therefore, the sale of Brazilian sequoia is likely to be banned soon, and the bow-making industry will be directly affected. At the same time, in order to meet the demand of the international market, local residents began to plant Brazilian mahogany. I hope this will not only protect rare tree species, but also won't lose the wonderful violin sound of the symphony orchestra. However, the planting of mahogany has just started, and it will take at least 25 years for the tree to meet the requirements of making bows.
