A new global study concludes that 90 percent of all large fishes have disappeared from the world’s oceans in the past half century. Another cause for extensive fish extinction is the destruction of coral reefs. This is caused by a combination of factors, including warming of oceans, damage from fishing tools and infections of coral organisms promoted by ocean pollution. It will take hundreds of thousands of years to restore what is now being destroyed in a few decades.
