Answer:
A. Genetic Biodiversity
Explanation:
All in all, many products that make up food, medicine, and supplies for humans are enhanced by the components of biodiversity.
Similarly, a lot of components that make up our medicines usually come from environments that have extravagant amounts of biodiversity.
Case in point, the country of Madagascar is where most of the formulas of our medicines come from, and it has some of the most vibrant & biodiverse tropical forests in the world.

Explanation:
Sediment discharge was historically approximately 270 million cubic meters/year of suspended load and 130 million cubic meters/year of bedload. This has decreased 80% since 1850 and can be divided into three periods: historical period (pre 1900), pre-dam period (1932-1952), and post dam (1963-1982). Suspended sediment loads declined 43% between the historical and pre-dam and 51% from pre-dam to post-dam periods. The size of sediment also decreased drastically including a 72% decrease in the sand fraction. Most of this is due to dams on the tributaries acting as sediment traps primarily for the coarser sediments. Large-scale land clearing for agriculture contributed to increased sediment loads in the historic period.
