There are lots of questions: what do if the meteor hits the Earth? How to survive in such terrible situation? But the most frequently asked question is what are the consequences if large object hits the Earth? The guideline of the paper is to determine characteristics necessary for survival and to determine possible consequences. Preserving the Diversity of Life: Meteor Hit Nowadays it is thought that dinosaurs suffered mass extinctions as the result of the comet or steroid.
Remained craters proved that the Earth was regularly battered by huge meteors or comets. Recent investigations show that the impact may be terrible and disastrous. There are lots of questions: what do if the meteor hits the Earth? How to survive in such terrible situation? But the most frequently asked question is what are the consequences if large object hits the Earth? (Grieve 1990) Firstly it is necessary to say that the positive moment in such situation is that atmosphere of the Earth shields us from objects that are initially below about 100 meters in size because they break-up and evaporate before reaching the ground. It is admitted that the consequences depends on the meteors size.
The possible consequences are: Meteor can destroy areas similar in size to Paris or Washington Meteor can destroy urban areas Meteor can affect ocean and as the result can produce large tsunamis Meteor can affect climatic conditions in the area, can cause destruction of ozone, and coastal communities Meteor can destroy the whole nation and cause fires Meteor impact can cause mass extinction. Long climate changes and global conflagrations (Gehrels 1996) It is seen that the possible consequences are really terrible and people should be taught how to behave in such situation, because meteor can destroy their homes, their things, their lives everything. People living near the ocean should be afraid of tidal waves other should be afraid of earthquakes caused by meteor hit. And only strong and healthy people are able to start their lives from the very beginning. Our society has real chances to protect themselves from such catastrophic impact. All people need is to make an effort.
Firstly people need to evaluate the possible hazard and to identify the consequences more exactly. The necessary characteristic is peace of mind. There is no need to spend large sums of money on investigations if the effects will be anyway the opposite. The next step is to estimate the populations of dangerous objects, and determine the orbits of dangerous objects. And the last step is to develop techniques which will be able to divert potential meteors and to prevent catastrophic situations. For example solar sails can be used.
The other possible ways are to support of the detection programs, to perform laboratory tests and to establish information systems. (Dickinson's 1994) But what should people do in such situation? It is necessary to prepare yourself and the family for possible consequences and actions. Family should plan emergency procedures and work out plan for family reuniting. Family members should know how to turn off electricity, water and gas and know emergency telephone numbers. It is very important to stay calm in such situation. One can stand away from electrical lines, telephones, trees and buildings, because meteor can cause short circuit while hitting. (Grieve 1990) The necessary survival suppliers are water, extra eyeglasses, can opener, blankets, spare batteries for radio, plastic bags, ground cloth, feminine suppliers, hand soap, toothpaste, etc.
all these things are needed if meteor hits the house. For safety it is necessary to prepare heavy shoes, heave gloves, candles, razor blades and clothes. One has to take also axe, broom, shovel, screwdrivers, pliers, hammer, rope, plastic tape, paper and pen. These things are of first necessities.
The positive traits are orderliness and calmness whereas negative are haste, panics and hysterics. If meteor hits the Earth it is necessary to preserve diversity of life in the Earth. Evolution and selection are natural processes of nature. Only organized and strong people can survive n difficult situations. Heredity would be also affected, because disasters cause serious changes in the lives of all people. (Dickinson 1994) References Gehrels, T. (1996).
