How many of us think  about the Sun and Sea, when you drink ‘Mineral water’ from that ‘PVC bottle’; or think about the PVC cables that transmit power to your home; or  eat  meal with a pinch of salt or bicarbonate; or when your municipal water treatment plant use Chlorine to disinfect your drinking  water? All these come from sea water energized by sun’s light, day after day, for several decades.

Every year 111 billion liters of seawater are evaporated using solar energy to produce 1.1 billion liters of brine. The amount of solar energy required to produce this, is equal to 11 million tons of coal, valued at US$ 1.10 billion. The brine is then crystallized to produce 2 million tones of solar salt, the essential raw material for 18 basic inorganic chemicals, including soda ash. Soda ash and Caustic soda are two fundamentals raw materials to chemical industries, as steel is to the engineering industries. This above statistics applies to one single manufacturer, and there are hundreds of manufacturers around the world.

Sun and sea are two great gifts of Nature to mankind. But industries use three great resources  namely Sun, seawater and a vast stretch of land often free of cost. Companies convert  seawater  into  salt using sun’s energy, manufacture valuable chemicals, sell them with profits   and then dump all toxic wastes on the soil and discharge all the industrial effluents back into the sea, polluting not only the source of their raw materials but also killing thousands of marine species they call ‘sea’ as their home.

Governments and EPA (government agencies) turn a blind eye to such pollution and give them clearance year  after year in each country for several decades, because they depend on taxpayer’s money to run their Governments. The manufacturer use these natural resources free of cost or at a fraction of  cost and make huge profits to their shareholders and pay tax to the Government, to make sure  that Governments don’t interfere with their activities. What is really happening is few rich and powerful are able to exploit the natural resources and enrich themselves with the help of Governments  at the cost of earth, water and air, we human beings habitat.

This avaricious exploitation of Nature has driven not only human beings but many animals and species to extinction. Basic needs of life such as water and air are polluted, man-made waste are dumped indiscriminately on soil, polluting the earth and ground water. The plastic manufactured using Nature’s sun and sea water, are dumped back on earth as non-biodegradable pollutants. This is how we repay Nature.

Human beings have caused an irreversible damage to Nature in the name of science, technology and industrialization at the cost of future generation, while enriching few rich and powerful. The damage is irreversible,  because we are forced to continue the same path to avert any disruption to our growth story. As long as we value materials over morals and ethics, there is no future and Nature will eventually turn its back with vengeance. We value how much a person is worth financially  rather  than, what a person can contribute to the uplifting of human beings and Nature. This is the crux of all problems in the world, including the financial crisis we are currently facing. We created the monster called ‘materialism’ and the same monster is now destroying humanity.

 

 

 

Carbon is the backbone of an organic life on earth. Every life from the smallest microorganism to human beings is made up of carbon. A cycle  called ‘carbon cycle’ that decomposes carbon into carbon dioxide which is used to synthesis Carbohydrates by the  process known as  ‘photosynthesis’ in presence of water and sunlight, as described in the following equation:

6CO2+ 6H2O   + sunlight →  C6H12O6 + 6O2

The oxygen generated during the above process and carbohydrates sustains life of animals and microorganism on earth. These lives consume oxygen and carbohydrates and releases Carbon dioxide by respiration into the atmosphere. The released carbon dioxide breaks down carbohydrates and other organic matters and regenerates carbon dioxide for reuse by animals and other lives. Not all organic matters are decomposed and part of it is stored as carbon biomass in the roots of plants and other organic matters and buried under earth. After millions of years these organic matters turns into fossil fuels under pressure and higher temperature. Carbon is distributed on earth, in water and in atmosphere. Due to increase in population and industrial growth over several decades the carbon dioxide increased gradually in soil, water and atmosphere. Carbon dioxide is also released by natural events like volcanic eruptions.

But the level of carbon dioxide in the atmosphere increased rapidly after industrialisation, when industries unearthed buried fossil fuels and burnt. In fact we are burning carbon at a faster rate than it is regenerated. It is purely man-made and it increases the presence of carbon dioxide both in atmosphere as well as in oceans. The rapid increase of green house emission started 240 years ago when industrial revolution started. The consequences of this unabated greenhouse gases due to combustion has caused ‘global warming’ with many consequences.

As I have mentioned in my previous articles, power generation and transportation are the two major industries that emit bulk of the greenhouse emission. Both industries use age-old technologies of combustion. The world has been complacent about fossil fuels and grossly indifferent to industrial pollution for decades. Global warming is looming as the biggest threat of the twenty-first century, yet we are not acting. Politicians deny global warming and they want to carry on the business as usual, at the peril of the future generations.

Powerful countries like US, China and India are reluctant to pass a unanimous resolution to set target for carbon emission, while smaller nations remain as powerless onlookers. These powerful nations can drag the rest of the world with them to face the wrath of the Mother Nature with disastrous consequences for their inaction.

It is quite obvious that world have no choice but switch to cleaner energy sources and leave the fossil fuels buried deep under the earth. A new paradigm shift in the way we generate energy and use them is the key for the survival of mankind. We need to develop Hydrogen as an alternative fuel source and Government should encourage innovations in such technologies, while they simultaneously price carbon. In the absence of a concrete legislation and mechanism to penalize polluters, industries will continue to use fossil fuels. A simple cost benefit analysis will show that taxing on polluters and simultaneously introducing renewable technologies will benefit the world in the long run.
