Survival of the smallest!

In a billion years from now, the Earth will be inhabited just by microbes. Not animals, not cockroaches but microbes. This conclusion is a result of a computer model used by researchers to predict the status of life on Earth after a few billion years.

As years pass by, the augmenting luminosity of the Sun will create an unfavourable rather intolerable environment for humans, plants and animals alike on our planet. The increased temperatures of up to 100 degrees Celsius  will lead to the evaporation of oceans which in turn will lead to increased salinity of large water bodies, high atmospheric pressure and a drastic reduction in oxygen and carbon dioxide content. The poisonous, high pressure, high salinity and zero-oxygen condition will only be withstood by organisms that already survive under such extreme conditions and are called “extremophiles”.
Desert ants sprinting on scorching sand, spiders in snowy areas and beetles with antifreeze blood are some of the creatures identified as ext…
