Kiobel and other environmental activists were arrested, tortured, and executed by the Nigerian military in 1995. They had been protesting Shell\'s oil exploration in the Ogoni region of Nigeria. A lawsuit was brought by Kobel\'s widow and others under the Alien Tort Statute (ATS) in the United States...
The loudest sound produced by a living organism on Earth is made by the bowhead whale (Balaena mysticetus). These whales can produce a sound that, if heard in air at a distance of 3.00 m, would have an intensity level of 127 dB. This is roughly the equivalent of 5000 trumpeting elephants. How far...
