~ Doomsday., Who was not afraid of the coming day. Various theories flourish about how the apocalypse is coming. Ranging from climate change, disease, and even aliens invaded the earth.
Many examples of science fiction film depicts how fearful doom. One of them After Earth, describing the apocalypse caused by natural disasters as earthquakes, floods, and tsunamis. However, many scientists worry that the film scenario becomes a reality.
Here are some causes of doomsday scenarios, according to the scientists:
Global warming.
Many scientists say that the worsening global warming could result in 'the world ends'. Climate change may alter extreme weather, drought in various places, to rising sea levels. Of course this can affect human survival that may lead to the apocalypse.
Asteroids.
Many science fiction film depicts how frightening to asteroid impacts Earth, the one that tells Armageddon. Meteor hit the earth to even make the dinosaurs extinct. In 1908, in a meteor smash Siberian forest land with an area of 2,000 square kilometers.
Attack the plague.
Whether we realize it or not, that the development of disease outbreaks can eliminate the human race. Outbreak of Severe Acute Respiratory Syndrome (SARS), Mers which originated from Saudi Arabia, and the latest Ebola. The spread of viral or bacterial disease outbreak is more apt to occur in view of international relations. "The threat of disease outbreaks is real," said Joseph Miller, in the textbook Biology.
Mushrooms.
Maybe people think that the really deadly bacteria humans, but also to note the presence of mold. Curator Museum of Vertebrate Zoology, David Wake said, "The threat of potentially dangerous bacteria, but the threat is more terrifying mushroom"
Engineering diseases. Not only penyakitalami dreaded plague, but also engineered disease. In 2011, the community of scientists discovered the evolution of the H5N1 bird flu virus.
Nuclear war.
Many scientists are concerned about the classic problem in the past recur, nuclear war. North Korea and Iran continues to develop nuclear power and feared to destroy the world.
Robot Attack.
You surely know the science fiction film The Terminator, the story of a robot that attacks humans. Apparently, scientists predicted the future will no longer be imminent. Many scientists think that human intelligence to create robots is increasing. But creating a robot to assist human performance still continues to be debated.
Human population explosion.
Fears rise in the number of people has occurred since that time the 18th century Thomas Malthus predicted growth would lead to famine and chaos on earth. Currently, the earth is inhabited by about seven billion people and growing. Population explosion problem really be a threat the world. There is also a debate that increasing population growth will actually make the world a stable 30 years.
Snowball effect.
Of the various possibilities apocalypse happens, scientists have suggested that the snowball effect most likely to occur. Snowball effect occurs due to the increasing global warming so that climate changes, too. Ecosystem be destroyed resulting in a decrease in food production. "Doomsday occurs not because of a big thing, but small things that continue to grow," said Miller.
Doomsday may be unavoidable, but the occurrence can be slowed. Always be alert and loving environment is the key.
