自然災害是人類生存和發(fā)展的巨大障礙。那么，自然災害究竟該怎么去定義呢？有沒有什么可行的預測方法用來避免或減少災害帶來的人員傷亡和損失？

The definition of natural disasters is any catastrophic event that is caused by nature or the natural processes of the earth. The severity of a disaster is measured in lives lost， economic loss， and the ability of the population to rebuild. Events that occur in unpopulated areas are not considered disasters. So a flood on an uninhabited island would not count as a disaster， but a flood in a populated area is called a natural disaster.

All natural disasters cause loss in some way. Depending on the severity， lives can be lost in any disasters. Falling buildings or trees， freezing to death， being washed away， and heat stroke are just some of the deadly effects. Some disasters cause more loss of life than others， and population density affects the death count as well.

Then there is loss of property， which affects peoples living quarters， transportation， livelihood， and means to live. Fields saturated in salt water after tsunamis take years to grow crops again. Homes destroyed by floods， hurricanes， cyclones， landslides and avalanches， a volcanic eruption， or an earthquake are often beyond repair or take a lot of time to become livable again.

Scientists， geologists， and storm watchers work hard to predict major disasters and avoid as much damage as possible. With all the technology available， its become easier to predict major storms， blizzards， cyclones， and other weather related natural disasters. But there are still natural disasters that come up rather unexpectedly， such as earthquakes， wildfires， landslides， or even volcanic eruptions. Areas that are not used to disasters affected by flash floods or sudden hail storms can be affected in an extreme way.

However， despite the many natural disasters the world over， mankind has shown amazing resilience. Many people talk about when a disaster has hit and their neighbors and countrymen have come to aid regardless of their own loss. People will step in and donate items， time， and skills in order to help those affected by a natural disaster. Celebrities will often do what they can to raise money through concerts， phone marathons， and visiting affected areas with aid. People have also shown that they can rebuild and lives can be remade or start over.

Its clear that natural disasters are a part of life as we know it. However， science is making it more possible to predict， aid is faster at coming， and people are learning how to rebuild in safer areas.
