Renowned scientist Dr. Ajai Kumar Sonkar, awarded with Padmashree, told our correspondent in a conversation that recently, during the study of species diversity of organisms in the South Andaman sea, an investigation was conducted by him, collected samples from 3 feet below the sand of the bottom of the sea about 150 feet deep. Laboratory testing revealed the presence of hydrogen sulphide in the sample.

Hydrogen sulphide is a very poisonous gas for all living beings and plants including humans, but for some bacterias, Hydrogen Sulphide is a life-giving gas, and oxygen is a deadly gas for them.

Naturally, Hydrogen Sulphide is produced by decomposing organic matter, dying and decaying organisms, crude petroleum, natural gas, volcanic gases, liquid manure, sewage and in the absence of oxygen.

If only 500 of its molecules are mixed in 1 million molecules of air, it can kill a person within five minutes, and a concentration of more than 700 ppm can cause the death of even the largest organisms in less than a second. This dangerous chemical is sitting at the bottom of the ocean.

Dr. Ajai told that the ocean has a circulatory system under which the water at the South and North Pole collects oxygen from the cold winds blowing from the Arctic and Antarctic. Cold water, being heavy in desity sinks to the dark bottom of the ocean, where it also takes oxygen with it to the bottom. There it is used by the organisms living on the bottom, from there this oxygenated water flows in the dark bottom of the ocean and reaches the equator and as the temperature increases, it comes to the surface and comes out. In this way this life-giving cycle continues. Through this excellent circulation system, oxygen is supplied to the dark bottom of the sea.

But due to our destructive development activities the environment has become sick and the earth is continuously getting warmer.

When the surface water of the ocean becomes warm, it becomes less dense than the water at the bottom and cannot sink to the bottom. Due to which such a system is formed that stops oxygen reaching the bottom.

When in the coming time, the surface water of the sea at the North and South Pole would get heated, then that water will stop going to the bottom of the sea, due to which oxygen will stop reaching the bottom. If oxygen does not go to the deep water, then the bacterias producing hydrogen sulphide will proliferate very fast. They will grow and fill that sea with poisonous violet sludge, then a cloud of yellow hydrogen sulphide will rise due to which there will be mass destruction of all the animals and plants in the sea and on the earth.
