At the BBC's annual Reith Lectures, physicist Stephen Hawking predicted some reasons that could lead to the end of the world. However, to a large extent it made in human. "Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or ten thousand years," he told the BBC. "By that time we should have spread out into space, and to other stars, so a disaster on Earth would not mean the end of the human race," Hawking says.
According to Oxford’s reports, there are 12 reasons may lead to the end of the world. Among them, The Worldwide Epidemic and Environmental Degradation remained the top of the reasons. “ We must prepared early on.” Hawking said, “ It may not happen in the last hundred years. It’s going to happen, but it’s not unavoidable. I am a optimist and I believe that advances in science and technology will avoid crisis in the future.”
The Worldwide Epidemic
Hawking warns that genetically engineered viruses could wipe out entire populations. Genes operate in ways that are not fully understood. Modifying one part of DNA doesn't always have the intended result—instead, it can create other unintended consequences, like the development of uncontrollable viruses. It could be only a matter of time before antibiotic-resistant viruses that we never imagined could exist actually develop, Hawking says.
But the really scary part is that the prediction is happening.
May 26th 2016, American scientist found the first case of super bacteria which has all the features of The Worldwide Epidemic: Incurable (as Ebola virus) , has much more lethal form (as hydrophobia) , has more strong infectious ability (as influenza) , has long incubation period (as Aids).
The Centers for Disease Control reported this May that this strain of bacteria has now been found in a 49-year-old woman in Pennsylvania. The supervisor of The Centers for Disease Control and Prevention, told the meeting the outbreak is "not winding down" and "widespread transmission" continues. “ It’s very dangerous.” the supervisor said. The CDC says there have been 5,469 confirmed cases across most of the United States, but Schuchat has said this is only the tip of the iceberg.
But how to solve this problems? The scientists could not find a way to help this. The World Health Organization has declared the super bacteria a "public health emergency of international concern" that could become a pandemic, or global outbreak of serious disease.
Environmental Degradation
The end of the world in various editions has massive natural disasters. Environmental Degradation will take global warming, toxic oceans, species extinction and so on. We have ourselves to blame most of the time, scientists and disaster experts say.
According to AP, more than food crises, global warming threatens to create serious harm to the planet. Intergovernmental Panel on Climate Change said that we are generally thought that high temperature and carbon dioxide has the benefit for plants, but actually it reduced grain production. Because of global warming, the data show that the rate of production increase has been ratcheting downward, even some regions consecutive months the production rate of zero phenomenon.
“ It is a disaster.” the supervisor of Intergovernmental Panel on Climate Change said, “ An developed country can supply food to its citizen, but the developing country cannot always produce enough food for its own need.”
But the influence is not restricted to earth surface, oceans have also been deeply reflecting. Rising sea-surface temperatures and increasing acidification only exacerbate marine ecology problem.
This is not a problem of shortage. As everyone knows,global warming could result in a significant rise of sea levels. That means 40% of human who live near the ocean will have turbulent life of swaying. Their very existence is now endangered by changes in ocean movement and rising sea temperatures, which also threaten the entire reef ecosystem.
Worst of all, by 2100, this could have altered two-thirds of the rainforests in Central and South America, about 70 per cent in Africa. Besides climate change, the collapse of the earth's ecology is also a future danger. The greenhouse effect, the acid rain, the pollution and the felling tropical rain forest can change the ecosystem. Whole populations of animals are in danger of disappearing.
“ In this case, reduce the carbon emissions and developing low-carbon economy become a pressing task for every country. Carbon emissions must be reduced (worldwide) at 10% annually if catastrophic climate change is to be avoided.” the supervisor of TCG said.
According to investigation, when car is working, spark plug ignites fuel and combustion produces power. This process will produce a large number of nitrogen dioxide, it will increase acidic material in atmosphere and cause acid rain.
Fortunately, every government is acutely aware of the severity of the problem and is working to fix the problems. “There are no two ways about it: to have any chance of avoiding the disastrous consequences of exceeding our carbon budget, we must usher in a new era of low-carbon societies.”
In China, Mexico, USA, Canada, Singapore, India, Malaysia and etc, they used a newest technology to solve the problem of excess carbon emission. “ It’s a newest carbon clean machine. If the car carbon emission is the 60% of global carbon emission, the HHO Carbon Clean Machine can reduce the carbon emission as much as 80%. “ The director of Singapore environmental protection agency said, “ We are plan to introduce the HHO carbon Clean Machine into our market and wish to make a contribution to our environment.”
