The real sea🌊🌊

 When we look at the sea, we see it as the most beautiful thing created by nature .

But we do not know that there is a very different aspect to it than we can see. I knew it last time i went to see the sea.

one person come up to me while taking a series of photos of the. Ocean and said, "These are more invisible aspects than you see here"

He than went onto emphasize the aspects i had not see in this vast ocean.

" Sea is a storehouse of treasure in the form of uncountable life forms of which a lot more are yet to be discovered. Also it is a storehouse of minerals. Sea is a very mysterious place and due to its vast nature it always drives human beings curious about it.

The nature of sea is different at different places because of various geographical features surrounding it. At some places the salinity is so high that human beings do not drown in that sea. And of course no living thing can survive. The seas and oceans are the reservoir of the most important ingredient in our food. I.e. Salt.

The sea provides livelihood to many fishermen and villages on the seashore. The sea is home to a lot of life forms of which some are very important for humans because of its high demand and nutrition. For example fishes, shellfish, mammals and seaweed. These are both harvested from wild and farmed.

The sea contains some form of life or the other at every part. Of course the sunlit areas are very less in deep sea. Also the penetration of light is effected by turbidity of water, surface tides, etc. So the sea vegetation is adapted to photosynthesis at minimal light available to them. The same goes to some fishes and other marine animal. The oxygen is also very scarce in deep seawater.

Essential aspect of human life such as trade, culture, travel, power generation and mineral extraction are provided by the sea. Sea is important during warfare too.

Sea imposes many weather conditions on the earth such as hurricanes, typhoons, cyclones, tsunami, earthquake, volcano, etc. mainly at lands which are in direct contact with the sea. These areas are very vulnerable to earthquakes especially if the epicenter is in the middle of the sea. Same goes for winds and storms.

However there are various ways in which sea, oceans and the marine life are threatened by man made reasons. Earlier killing of whales was not done judiciously. The fish oil is used for many purposes. This had led to lessening in the number of the whale fish. So now it is not legal to kill whales above a certain limit. The sea is exploited a lot for mineral extraction too. This again seems to exhaust the resources available. So now boundaries have been given to the major countries who are dependent on the sea for resources in the form of few hundred nautical miles counted from their land. Exploiting resources beyond that limit is illegal. Before the imposing of these laws overfishing was also a problem but not now.

Then, releasing of industrial sewages and waste products containing harmful chemicals also effects the marine life available.

Global warming have also effected marine life by increasing the temperature of the seawater and oceans. This increase however small have resulted in lowering of availability of dissolved oxygen. And so the marine animals are affected by it very much.

The sea finds a special mentioning in our tradition and folk tales too. The tales of pirates, traders losing their treasure somewhere at the middle of the ocean or sea is common. Even in our religious Scriptures or epics, there is special mentioning of sea.

So overall we can say that seas and oceans have a lot of secrets still not unveiled properly by humans. It will continue to amuse humans as he will try to reveal those secrets one by one".
