Question

Until a few thousand years ago a man was merely a hunter on the earth. Not until the

Neolithic period did he begin to settle down to agriculture. By tending the soil he was

able to increase his food supply without roaming over large areas in search of it. And

he has continued to improve his practice of agriculture; until today he is able toproduce greater and better yields from the soil than it ever gave before. But as far as

the seas are concerned, he is still almost entirely a hunter. He catches fish and other

aquatic animals but does little to encourage their growth and continued supply. So far,

his under-water hunting has yielded him considerable supplies of highly nutritious

protein to supplement the supply he gets from his farming of the land. But with the

growing increase in world population Man may soon need so much protein from the

sea that its supplies, enormous but not inexhaustible, will be in danger of running out

unless Man takes steps to maintain adequate supplies through some form of sea-

farming.

Fish- farming on a small scale had already been successfully carried out in fish ponds

and in lakes, especially the artificial lakes created by the construction of dams for

hydro-electric projects. Already the protein supply has been increased by the yield

from fresh-water fishponds. Some of them developed in rural communities with the

help and supervision of agricultural officers.

Once fish ponds have been stocked with young fish, it is fairly simple to give the fish

healthy surroundings to grow in, and see that they have an adequate supply of food

The basis of all water feeding is plankton, the name for very minute plants and animals

which float in great numbers on the water. The small fishes feed on this, and in their

turn serve as food for the bigger fishes. Since plankton itself depends for its growth

on the presence of certain minerals in the water, the amount of the plankton can be

increased by the addition of fertilisers to the water, just as we fertilise the soil for

growing plants.

However, several problems will have to be solved before the farming of the oceans

can be both practicable and profitable, for instance, there would be no point in

fertilising a portion f the sea if the sea currents are going to scatter the fertiliser away

over miles and miles of unproductive water. Even if the fish-farmer could restrict the

fertiliser to a definite area he would still have to find a way of keeping within his

‘own’ area the fish which his fertilisers had fed to maturity. And to get the maximum

returns for his expenditure he would have to find a way of keeping the food to the fish

he wants to feed. This would involve some sort of weeding – removing the numerous

inedible water creatures which would be sharing the sea-food with ‘his’ fish.

Obviously these problems will not be very easy to solve, especially when we

remember the vastness of the ocean nearly three-quarters of the surface of the Earth.

And the water of the seas, unlike those of ponds and some lakes, are constantly

moving about in currents. Most probably the problems will be solved gradually; in

the foreseeable future Man may start fish-farming on a small scale in the shallow off-

shore waters near the continents. A further development of the aqualung already in

use with some form of under-water tractor for moving out and doing simple jobs, he

could fence off and area of water, he could then stock the area with the particular

types of fish he wants to grow, ’weed’ it by removing undesirable aquatic animals

which may reduce the food of his fish, fertilise the area when necessary, and finally

gather in a harvest of mature fish from time to time.

Even when this stage has been achieved however the problems to be solved before

the open seas can be similarly turned into fish farms will still be tremendous, But if

the time ever comes when of necessity they have to be solved to obtain sufficient food

for a greatly increased world population, then Man will certainly solve them, as he

has solved similar difficult problems in the past.

Answer 1

Answer:

The epistemology of loss of the ball is that every one loses things in life but one has to forget it . Loss is an abstract idea. In a world of possession, there will be losses. No matter how many times one gets another thing innthe place of the thing he hast lost, the experience is always new and fresh.
