FUTURE EARTH

By Aditi Jori and Isha Lawate (VI C)

The earth is 4600 million years old and is expected to have a natural life of another 6000 million years. What will the future hold? Living things, in one form or another, have existed for atleast 3500 million years, undergoing constant change and evolution. What will the future living things be like? How long will the human survive?
In the short term, the one thing scientists have agreed upon is that the earth will become much warmer. This is known as GLOBAL WARMING. The average temperature has risen by more than 0.5 C in the past century. This is predicted to rise to 2 C by 2050. The effects may be felt as more violent storms, shifting rainfall patterns and rising seas, which could submerge many of the worlds coastal areas. Many scientist believe that the emissions of certain gases-chlorofluorocarbons (CFCs), carbon-di-oxide and methane from factories, cars and power stations may contribute to “green-house effect” , a likely reason for the rise in global temperatures.
In the longer term – millions of years into the future- the earth itself will continue to change. Rivers and glaciers will erode upland areas, creating new lowlands. These may then be uplifted, creating in turn new uplands. The continents will go on drifting around the globe, creating or destroying land-masses and ocean floors. Despite the probable destruction of a number of living environments by humans, life will go on evolving.
How will human kind cope with this change? The reduction of green house gases, by a switch to alternative forms of energy, could arrest global warming. A new approach to conservation may save some well known species from immediate extinction. In the longer term, it would seem very little could save our planet from an anteroid impact or cataclysmic volcanic eruption. The search for new planets to inhabit may provide a safe haven for people to survive such a catastrophe.
