In absolute terms, the planet has lost 52% of its biodiversity since 1970 according to a 2014 study by the World Wildlife Fund. The Living Planet Report 2014 claims that "the number of mammals, birds, reptiles, amphibians and fish across the globe is, on average, about half the size it was 40 years ago". Of that number, 39% accounts for the terrestrial wildlife gone, 39% for the marine wildlife gone, and 76% for the freshwater wildlife gone. Biodiversity took the biggest hit in Latin America, plummeting 83 percent. High-income countries showed a 10% increase in biodiversity, which was canceled out by a loss in low-income countries. This is despite the fact that high-income countries use five times the ecological resources of low-income countries, which was explained as a result of process whereby wealthy nations are outsourcing resource depletion to poorer nations, which are suffering the greatest ecosystem losses.

Ah, so.. unanswerable

When infection attacks the body, anti-infective drugs can suppress the infection. Several broad types of anti-infective drugs exist, depending on the type of organism targeted; they include antibacterial (antibiotic; including antitubercular), antiviral, antifungal and antiparasitic (including antiprotozoal and antihelminthic) agents. Depending on the severity and the type of infection, the antibiotic may be given by mouth or by injection, or may be applied topically. Severe infections of the brain are usually treated with intravenous antibiotics. Sometimes, multiple antibiotics are used in case there is resistance to one antibiotic. Antibiotics only work for bacteria and do not affect viruses. Antibiotics work by slowing down the multiplication of bacteria or killing the bacteria. The most common classes of antibiotics used in medicine include penicillin, cephalosporins, aminoglycosides, macrolides, quinolones and tetracyclines.[citation needed]

There is confusion currently as to the name of the eldest Vinaccia luthier who first ran the shop. His name has been put forth as Gennaro Vinaccia (active c. 1710 to c. 1788) and Nic. Vinaccia. His son Antonio Vinaccia was active c. 1734 to c. 1796. An early extant example of a mandolin is one built by Antonio Vinaccia in 1759, which resides at the University of Edinburgh. Another is by Giuseppe Vinaccia, built in 1893, is also at the University of Edinburgh. The earliest extant mandolin was built in 1744 by Antonio's son, Gaetano Vinaccia. It resides in the Conservatoire Royal de Musique in Brussels, Belgium.
