It is estimated that 27,000 species become extinct each year, about 3 an hour. Since 1996, scientists calculated that 124 types of amphibians, 1,108 types of birds, 734 types of fish, 1,096 types of mammals, and 253 types of reptiles became endangered.
35,150 animals become extinct every year.
Cheetahs aren't extinct...
Spider monkeys are not extinct.
That isn't a simple question to answer. Animals don't become extinct in a matter of months or even years. Long-term factors slowly reduce the population. The fewer animals there are, the more congested the gene pool becomes and the smaller the knock that is needed to push the species over the edge. Extinction is a gradual process, and there are many cases where 'extinct' animals have been rediscovered, tens or even thousands of years after they were believed to have died out. Cases in point: Caelocanth and Leadbeater's Possum. An animal is classified as extinct when no living specimens have been (reputedly) sighted for more than (I think this is accurate) ten years. So it's impossible to say what animals have died out this year. If the last sighting of the species was last year and in ten years time there has not been another, that animal will be said to have become extinct this year.
lets say alot because they get killed or sick that is sad :< p.s. like thousands!!
Extinction rates vary and can sometimes be rapid, and some times slow. Extinction rates are affected by biotic, competition between species, hunting etc, and abiotic factors, volcano eruptions, weather etc.
no one knows what will happen. if the do eventually become extinct then probably in the year 9000 some one who is a scientist will find a fossil that is a humpback whale and technology will be be able to recreate extinct animals and then they can have more humpback whales again. you never know. besides that was an educated guess.
There are lots of animals that will

Gemstones are not alive, and therefore cannot become extinct. There are plenty of gemstones around, and more are found each year.
five or six species...
