A shard of water

The scene from the balcony of my apartment in the third floor of the building is breathtaking. It harks me back to my childhood. The place where all these apartments have come up were fields earlier. There were rills with gurgling water running through the path which led us from our home into our land.

Now this patch which is remaining reminds me of those times. There are fields in which the cattle graze when the land is fallow. In the rainy season, the cattle roll in the mud and after that go to bath in the pond of water.

This pond looks like a shard of mirror. It is a narrow strip of water. I was surprised why the pond does not get dried. Still there is water. This time I found the answer.

There is a river not far from our place. It is called Ghaghar. It is not a big river like the other mighty rivers of Punjab. In the past, as I have mentioned, there were small streams which ran through the area and distributed the water for irrigation to the landowners on the rota basis.

I have presumed that all those stream must have become extinct but I was surprised to see one in which pristine water was flowing and leading towards the pond and beyond.

There is a narrow path made from the constant walking of the people. It is narrow strip of bald land. People who are walking on the path look tiny specks from our home. During the high sun, the water simmers and it becomes difficult to look at it directly.

From the height of our home, the pond seems to like a broken piece of mirror-placid. But a closer look indicates lots of activity taking place there inside it. Buffaloes wallow in it.

Besides you can see the cormorants and ducks smoothly swimming over the water surface. Water continuously exits the pond from other side.

There is algae over a part of it. The same algae called cyano-bacteria or green algae which is on the surface of the earth since times immemorial when no other form of life existed. This is the same algae which is the precursor of life that is present on the earth.

On the other side is a preserved patch of woods where eucalyptus and poplar trees grow along with undergrowth. There are trodden paths running and getting lost inside these woods. These remind me of the poem “the road less taken” by Robert Frost.

I don’t know how long this patch of remaining land will last. I fear the day is not far when the demon of concrete will overtake it. In the last I present a picture of laborers carrying dried wood stick bundles on their heads for firing their hearths and sitting around the fire for keeping the winter at bay.

Algae: A machine to make energy

In the beginning there was carbon dioxide, water and sunlight on our Earth and its environment. The same carbon dioxide which is the end product of today’s industrial processes. The factories spew carbon dioxide.

Scientists are finding ways to fix this carbon dioxide which is the major cause of greenhouse effect and results in trapping the heat and disallows it dissipate and result in Global warming.

Whereas in the present climate living beings mostly use oxygen to breakup the food and convert it to glucose and energy, in the beginning only organism that thrived on carbon dioxide was called green algae.

It mastered the art of harvesting sunlight by a process called photosynthesis in which it converted the freely available carbon dioxide and water into glucose which it used as food. But along with the glucose, another product was formed which we call oxygen and cannot live without.

Now the families of these algae, again seem to be rescuing us from the crisis of energy. The mineral oil and coal, major sources of energy are not inexhaustible and considering there rate of consumption, there is a concern to find the alternate sources of energy. One example is ethanol manufacturing from the corn.

Algae is holding the promise to save us again. The green covering on the ponds looks very unattractive but these tiny globules contain lipids which can be converted into the biofuels.

Some of these also contain hydrocarbons. These algae sequester the carbon dioxide infused into the environment and helps cleaning the atmosphere.

At this stage, efforts are on to increase the yield of biomass and make it commercially viable. For this favorable conditions are being created to grow the algae into the open ponds where yield shall be more due to availability of sunlight also.

Algae is attacked by some aquatic species called rotifers. Efforts are on to create the media which shall do away with all these problems.

Besides the energy in the form of lipids, there are algae which are excellent diet supplement because they contain a myriad number of minerals and proteins.

One such algae is spirulina which is very popular among the people who want to become slim by shedding the weight.
