Where native large crocodilians and humans live close to each other, crocodile attacks on humans occasionally occur. In fact, only 9 out of 23 crocodilian species are considered dangerous to adult humans. Notes 1 And in those six species, only individuals 2 meters (6.6 feet) and longer in length are capable of killing adult humans. Two species, which are also the largest and most aggressive, saltwater crocodile and Nile crocodile have a well-known reputation for preying on humans. These two also have the most documented cases. Each year, hundreds of people die of either Nile or saltwater crocodile attacks. The mugger crocodile, which can be found throughout the Indian subcontinent and the surrounding countries, also very dangerous to humans, killing many people in India every year. Despite the American crocodile is considered to be less aggressive, a few (unverified) fatally attacks reported. Also, species/individuals smaller than 2 meters can inflict painful and dangerous bites on adult humans and they even capable of killing children. Even then, according to the Worldwide Crocodilian Attack Database most interactions between crocodiles and humans are non-eventful.

Carl Sagan’s famous quote says “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” In that famous quote, Sagan makes reference to the whole universe started off with hydrogen and helium, all stars produce helium, and then stars over a certain mass threshold produce carbon, nitrogen, oxygen and lots of heavier elements – which are also the source of the life. The star stuff is inside us – every living thing on Earth.
But, even stars aren’t powerful enough to create heavy elements like silver, gold, and cesium. Since the 1950s, scientists have wondered: where do most of the elements in the periodic table come from?

On May 12, 2008, a huge 7.9 MW earthquake hit Chengdu, a sub-provincial city which has served as the capital of China’s Sichuan province. Over 69,000 people lost their lives. 374,176 were reported injured, with 18,222 listed as missing as of July 2008. The earthquake also left about 4.8 million people homeless.

Sichuan earthquake is only one example of (but the deadliest by far, though) many earthquakes that triggered by the human activities, according to a study published in the journal Seismological Research Letters, titled “Database of earthquakes triggered by human activity is growing – with some surprises”.
