Cerro Rico is located in Potosi, Bolivia. About eight million people are estimated to have died in the mountainous region. The death rate of Cerro Rico is high which made it earn the nickname, the Mountain that Eats Men.
The death is caused by the dangerous mountain terrain and the job hazard of mining which takes place in the area.
About eight million people are reported to have died in the Cerro Rico since the year 1545. Reason being why the mountain has it second name to be popularly known as "the mountain that eats men".
It was also reported that four to five workers are being killed every month from mining accidents and mining related illness. Also, as miner numbers are increasing so the number of deaths.
Moreover, as more men are dying from mining accidents, another major causes of death in the Cerro Rico is silicosis. Silicosis is an incurable lung disease caused by inhaling large amounts of silica dust. It is was unfortunate that this is the biggest occupational hazard ever throughout the entire world.
If you want to look at it from an academic standpoint then the most valuable fossil is the Holotype; the single specimen that was used to describe a species.
Explanation:
Holotypes are priceless, as they are the single specimen that defines the species.
Buffered solutions or buffers are solution which resist a change in PH when small amounts of acid or base are added. Buffers contain an acidic species to neutralize OH- ions and basic species to neutralize H+ ions Buffers are therefore made of weak acid-base conjugate pairs , such as HC²H³O² and C²H³O².
