Changes in the weather.

Nick Brooke, senior research assistant of the Research Center of the weather conditions, the Dallas Times. It is located in East Anchorage, Jagiellonian University. UK. Commented that "in the end of this century. The greenhouse is deteriorating. The average global temperature will increase by at least 2 degrees Celsius, the heat level is higher than the world has ever faced on one million five hundred years ago. The worst thing that could have happened in many parts of the world climate change entirely. Which may affect food production to feed the world population. And the social system that is currently in widespread erosion followed by a massive exodus of people. Problems of conflict and competition for resources. The area suitable for human life is running low, I do not think this change will make the air that humans extinct yet. But of course it will cause heavy casualties ".

Deterioration of Heritage Mir.

Rain hard in Stinson Beach Medical University of Vienna. That all living species. "Evolutionary clock" in the time of this biological clock. Be passed from generation to generation. It went back to the time leading up to the inevitable extinction of the "Heritage Mears is a closed distal chromosome present in all, if not at Lausanne and Mears. Chromosome may not be stable. Each time a cell divides, it will not. Carbons Heritage Mears completely and throughout generations Our Heritage Mears shortened shortened due to cell proliferation on its own eventually shortened penis. We began with diseases associated with aging such as cancer threats to Alzheimer's disease, heart disease and stroke, reflecting the poor condition of the individual. Heritage Mears and be passed on for thousands of generations, until it begins to erode the critical level on the day we met. That diseases associated with aging are dispersed throughout. Early age. The final population will cause shortages. Erosion of Heritage Mears may explain. The extinction of certain species such as Neil Anderson's allege. Without taking external factors into account changes in the weather. "

The outbreak of the virus.

Professor Maria Sam Bon virologist and influenza laboratory chief of the Office of Health Protection of the Kingdom of England, that "at the end of the previous century. Outbreak of serious influenza fourth round with an outbreak of HIV infection and SARS worldwide pandemics occur every hundred years. And the inevitable to happen again in the future, at least now believe that the most fearful strain of bird flu outbreak in the H 5 chickens in Southeast Asia. If this virus to learn how to submit. Infection from person to person then. The outbreak spread rapidly spread worldwide. The outbreak of the flu in 1918 killed 20 million people to the world population in one year than those who died in World War I, even. If the outbreak is now stronger than the impact. "

Rebellion

Professor Paul Wilkinson, Johnson, Chairman of the Advisory Board of the Center for the Study of Terrorism. And Political Violence, University of St. Andrew's. UK attitude that "society today is much more vulnerable to terrorism. Because that malice can be used for promotional material easier, including technology and expertise in creating highly destructive weapons. Terrorism that resulted in the deaths of a number of biological weapons and chemical weapons is now believed by some to release a number of things such as anthrax, smallpox virus could impact hugely. And communication. Boundary between the new era will quickly become an international problem "in an open society where we can come and go freely. We were unable to stop the attack at all. And there is a strong possibility that The attack took place somewhere in the world in our generation. "

Nuclear warfare

Air Chief Marshal Lord Garden Pentagon spokesman for the Liberal Democratic Party of the United Kingdom. And author of the book Can Deterrence Last? "In theory, then. Might undermine the glory of man. But in practice. I think that the danger may have passed the point where it may cause a nuclear war in the Middle East, including 3 of the India - Pakistan And North Korea. Of course, North Korea is the point. Most worrisome due to the old format and will trigger an accidental war. But I want to believe that there are still barriers that prevent the use of nuclear weapons is because we have developed the use of nuclear weapons against countries that "the possibility that a global nuclear war is very low. Although there is still the possibility that there may be a country opposed. Or is it extremist ".

Meteor hitting Earth.

Donald Yau Mansfield manager of NASA's Near-Earth Object Program Office. Jet Propulsion Laboratory in California, the U.S. has seen. "The risk that we will die of a meteorite hitting a rough edge. We would like the chance of death from a plane crash. Meteorites to make. The glory of man is lost, it must be a meteorite wide. Or approximately 1.5 km, we estimated that such events are likely to occur every million years on average. Hazards associated with meteor strikes Earth is a huge amount of dust that float up into space to block the sun shining down on the ground for several weeks. Which will affect plants and crops. Sustaining fire creatures may be the result of heat coming out from under the earth. And acid rain damage heavily. As mentioned, although this effect. Takes place in the short period of time, so the organisms that can adapt itself to the way humans have cockroaches and survive. "

Robots rule the world.

Professor Hans Mora vector of Robotics Institute. Carnegie Mellon University in Pittsburgh, PA. Discussed this issue. "With the robot control system. Complex processing increases. Doubling every year or every two years, but the complexity of it now remains only Vertebrate classes, but in the next 50 years, the ability to imagine the complexity of the robot to catch up with men in the year 2050, I predict that there will be a powerful robot. Equal human brain. They can think in the abstract. And comments.

The blast of cosmic rays from exploding stars.

Oldies Chawi physics professor at the Hebrew University of Jerusalem in Israel, said that every few decades. Massive stars in the Milky Way galaxy would run out of fuel and explode, which is called superclass Nova cosmic rays (high energy particles and gamma rays) will radiate out in all directions, and if the world is in the path of radiation. Will cause the ice age. If the world is cold weather anyway. Cosmic rays from the explosion of a star could become the world's ice and could cause species extinction risk when the orbit through the Milky Way spiral galaxy. This is a super site. Most Nova. Supernova explosion will occur every 150 million years.

Volcanic eruption.

Professor Bill McCormick, Mary Guido, director Ben Disaster Research Center Field of University College London and is a member of the Working education disaster, British Prime Minister Tony Blair. Talk about that. "On average, every 50,000 years, the world would be a massive volcanic eruption which sent volcanic ash ejected will cover approximately 1,000 square kilometers. Adjacent continents. Are filled with ashes. And sulfur are. Rise into the atmosphere. Sulfuric acid is a veil covering the light around the sun can not shine down upon the earth. Lunch will look no different from Twelfth Night. Chat damage major volcanic eruption in human history, the volcano Toba in Sumatra, Indonesia on 74,000 years ago due to an explosion close to the equator, the gas spread to the northern hemisphere and south quickly when studying ice cores indicate that event that resulted in a sudden drop in temperature after 5-6 years. By the Tropical region are cold as ice. "The opportunity to be a major volcanic eruption is possible over a large meteor hit Earth 12 times, but the possibility that it will happen in the lifespan of the current is only 0.15% of the property is to be policed. The area had been an explosion in the past, such as occurs in the U.S. and the Manitoba area. Another concern over the world. Potential volcanic eruption of violence in areas that had never happened before. Such as the Amazon rain forest. "

Black hole

Richard Wilson, Professor of Physics Research Mullin's survival or function. University of Harvard, said about seven years ago, National Laboratory Brooke Haven in New York has created the Heavy Ion called Relativistic Heavy Ion Collider is due to concerns that the material density. may form up like never before. In those days, that is the largest particle accelerator ever built. For gold ions collide with tremendous force. This could cause a dense enough to cause a black hole to suck up the energy of matter outside. Lab Brooke that cause fear. The new reactor would cause the black hole and the end of the world or not. "Based on what we have learned from the black hole in outer space. We conducted a study to calculate the particle accelerators of Brooke Haven can cause a black hole or not. We are quite sure. The lab will not cause a black hole. And the world will not be lost from the collision of these particles.
