The Holy Peepal Tree, etc.

Is conservation of nature a way of life for us? It may sound a bit surprising but the answer is more a ‘yes’ than a ‘no’. Yes, we cut trees, waste water and pollute the air with our cars. But sometime, we also participate in conservation of nature, though may be unknowingly. Let me make my point clear. Every time we pass by that neighbourhood peepal tree, we do a pranam. Yes, the tree boasts of a trishul placed by some holy saint long back and we are devotees of Lord Shiva. So we pay our tribute each time we pass by it. But let us look at this subject of our everyday worship a bit more closely.

India has thousands of such holy peepal trees spread in our cities and villages and towns. Now it is interesting to note that these peepal trees (Ficus Religiosa) are actually endemic to the Indian sub-continent (i.e Ficus trees are found only in the Indian sub – continent) and has great ecological and medicinal significance. Various parts of this tree is used in traditional medicine for about 50 types of disorders including asthma, diabetes, diarrhea, epilepsy, gastric problems, inflammatory disorders, infectious and sexual disorders. This is a tree that bears fruit all-round the year, thus supplying a continuous supply of food to the wildlife of the place where it is flourishing. Besides, it is home to many birds and animals like squirrels. This aspect of the tree assumes great importance specially in a city where wild life habitat and wildlife food are scarce. And such is our way of life that by attaching a religious sentiment to the peepal tree, we have always tried to ensure that these trees are not cut down.

This recent news, published on 22nd of May 2012 in an English daily called Greater Jammu (http://www.greaterjammu.com/2012/20120523/state.html) proves the point:

Jammu, May 22: Cutting of a ‘Peepal’ Tree at Cremation Ground sparked protests by various organizations including political, social and religious. Greater Jammu in its Tuesday’s edition published a news item under the title ‘Cutting of ‘Peepal’ in cremation ground evokes resentment’ following which various bodies and associations were today up in arms in one voice.
The protestors including the Rashtrawadi Shiv Sena today expressed anger against ‘Sewa Samiti’ and Jammu Municipal Corporation (JMC) for allegedly hurting sentiment of the community.

It is difficult to believe that the importance of these trees and their “sacredness” is a mere coincidence. Generally it is seen that species which give value oriented services to the ecology, economy and the community of a region are deemed as sacred by the people there. Of course, on the face value of it, their belief is not steered by any economic or ecological perspective; rather the whole guiding force for the people has always been religious.

This kind of ecological ethos are most common among the tribal people of the country. The North East region of India is home to many tribal and ethnic groups. The religious practices and folklores of most of these indigenous societies maintain a conservationist ethos which in turn has helped them to sustain their base of natural resource. There is the famous example of the Sacred Groves of Meghalaya. The trees in this grove are considered holy by the local people and it is believed that bad luck will befall the person who harms these trees. According to local belief, one, however does not face any harm if they utilize assets of such sacred groves (say, eat a fruit, etc.) right at the spot but it is considered ominous to carry the assets away from the sacred spot. Also, interestingly, if one unknowingly breaks the religious code, no harm will strike him. Such beliefs, no doubt, endear the concept of sacred groves to its immediate influence circle.

This kind of conservationist religious sentiment is not confined to the plant kingdom alone. A cursory look at our mythology will prove the point. The rat and the elephant are associated with Lord Ganesha, the owl belongs to Goddess Lakshmi, the swan is always seen with Goddess Saraswati, Goddess Durga is incomplete without her ferocious lion, the bull and the snake are the favourite of Lord Shiva, the cow is the friend of Lord Krishna, and so goes on the list. We hold these animals sacred and are opposed to harm them because their partners are our Gods.

We Indians are religious people and since ages, religion has made a conservationist out of us. What we need to do is consciously realize the conservationist sentiment behind our religions and try to incorporate them with greater meaning and greater role in our daily life.

Why Some Gases Are Deadly Dangerous – Odours

Everyone knows the dangers to health and the environment of spitting, rubbish-throwing, urinating and defecating on our streets. What we don’t know is that apart from hygiene issues, it badly affects our olfactory (smell) and other systems.

Odours, not only from garbage but also from sewage, and industrial processes disturb concentration and diminish productivity as our disgust with our environment remains uppermost in our minds.

At the same time, we tend to stoically ignore and not complain about our symptoms of discomfort. Productivity in such an environment goes down considerably. Our ability to perform tasks may decrease as our dislike for particular odours increases. Work force populations vary in levels of discomfort from odours because of exposure history and habituation. But whether we may, or may not realize the possible risks of consistent bad odours, they affect human health and well being.

We have varied reactions like eye irritations and sore throats, coughs, drowsiness, asthma and even depression.

“Unless we realize the vital need for planned urban development India will become the largest slum in the world. And, sooner than we think.” A dire warning from Tavleen Singh, if ever there was one.

When our cities get overcrowded by migrants, the well-off get assimilated more easily and their adding to the burden on the city’s finite resources is less visible. What problems do the poor face and how do they affect the city’s resources? Their living quarters are crowded and cramped. They either have relations in our slums or they encroach on our footpaths. They have nowhere to carry out their daily ablutions. It has to be public places.

One of the most obvious outcomes of unplanned migration to our cities has been garbage. The poor have no place to throw their garbage so it collects on our roads or clogs our waters. Come to think of it, our kachrawalis might take away our garbage from our flats but who knows where she takes it? In December 2010, when I was in Mumbai, I saw at least five huge MOUNTAINS of garbage in just one suburb, which were definitely not there the last time I was there. Our municipality doesn’t clear it away.

A Possible Action Plan: Perhaps we should all inundate them with phone calls or emails to come and clear it away from outside our homes. Perhaps we should get together, plan, organise and act in unity to ensure it is done. Perhaps we should find out who’s in charge of taking away our garbage and publish this person’s contact details online.

Garbage dumps shouldn’t be on our doorsteps to start with, but in designated places far away from where most of us reside. The municipality should take away our garbage regularly to these designated dumps. But it doesn’t happen. The garbage piles get higher and more densely compacted with their own weight causing all the above symptoms in our health.  Methane – a greenhouse gas that captures heat and causes global warming is one of the end products of these dense piles of garbage. This might be an appropriate place to mention how, with the advance of science, this methane from garbage is being used to make new energy. A very worthwhile investment once it is made. Who knows, we might see the last of garbage clogging our city streets yet. Whether the government and business get together to exploit the benefits of garbage to create new energy or not, garbage from our city streets has to go or we have to keep paying megabucks to doctors for our health.

Want to get involved? Getting together with other like minded people and speaking with one voice is one effective way to get our point across to the government. After all, whose voice is more effective? A billion lone voices or a billion strong force?

The Nature of Business

As we become more and more modern, our culture too becomes more and more modern. Yet more often than not, we cling on to our old culture and norms; we just wrap them with a modern cloak. We cannot discard the old ones so easily.

This is the age of business. Big business and small business. They cross our path and interact with us everywhere. They often overpower us and make us behave according to their will. (So we believe Lakme’ is good but still buy Revlon.) These businesses want to be as human as possible so that we accept them as our own kin. So much so, that these business, in the shape of companies, have started exhibiting human habits and have adopted human culture into their fold of actions. So they commit crime and so they redeem. So we get upset with them and so we forgive them. And sometime, we cannot but help being amused too at the same time.

For example, we are absolutely allowed to be amused if we get to know that one way of such redemption is manufacturing dry shampoo. Yes, dry shampoo. For the uninitiated, this comes in the form of a spray. You just spray this dry shampoo on your hair and bingo, the criminal oil is gone and the bounce is back. No water needed. And fast too. One big (actually very big) company to introduce dry shampoo in the market is Unilever. So what is the crime here? The answer is environmental. Rain forest destruction, exploitation of water table for massive manufacturing plants, greenhouse gas emission, etc. Is dry shampoo actually the redemption? Yes, one among many. 2 billion consumers use Unilever products every day. If all of them use this dry shampoo, think of the amount of water the world saves! So, for all the environmental harm that Unilever has done, they give us a dry shampoo so that we save water on their behalf. This is how companies behave; they make us behave according to their will. If you resist, Kareena Kapoor and ShahRukh Khan will insist that you use this dry shampoo. And everyone knows how bad we are at refusing Kareena Kapoor and ShahRukh Khan . But let’s look at it the good way. If we can, then why not? Yes, the whole idea is totally futuristic, optimistic and slightly overrated. But the idea is already borne and is in the market. The name is Suave – Dry Shampoo. Now in USA, soon to be in India.

We all have our bad hair day with no time to go through the long process of shampooing our hair; we are busy people. We all have our after-office parties. We all need to look good all the time. The answer is dry shampoo. So when Suave Professionals talk to consumers, they do not tell consumers that this shampoo saves water. They tell what the consumer is interested in: quick hair remedy. This is how business operates. It tells only what sells.

Necessary follies and redemption (read corporate social responsibility) – this too is how a business operates. Some say, these redemptions too are business. This too may be true.

The point is we have come a long way. While earlier redemption was a holy dip in the Ganga, now it has been bottled as dry shampoo. This is the case of old culture, modern cloak. And everyone wins. Unilever gets to redeem and its consumers get a quick fix of a shampoo with no strings attached. And if this is successful, it helps the environment as well, besides bringing profit to Unilever. All of these are good reasons for a company to innovate and thus find new ways of redemptions. The hope is that – in the process, nature too gets redeemed. This is the age of business and companies and profits. Business will have to find profitable means to save nature. And we all need to support such initiatives. Otherwise, we all are doomed.

The Persian Worry

“A sudden decline of the birds was noticed since 1995. Surveys in different parts of India carried out by the Bombay Natural History Society (BNHS) proved that the vulture population, especially the Indian white-backed, long-billed and slender-billed ones had declined by more than 99.9 per cent.” – 12 Feb 2011

The Persians, in many ways, are quite different from the followers of other religions. What deserves special mention is that they do not bury or burn the body of their dead ones; it is against their religious ethics to pollute the air, water, earth or fire while performing ones last rites. Instead they have tall towers called “tower of silence” where they put up the bodies of the dead – to be eaten up scavenger birds like vultures. But there has been a nose dive decline in vulture population in the recent times which has made the performance of this ritual quite a difficult task for the Persians. The problem is of such paramount importance to them that they have now started captive breeding vultures in an attempt to solve this issue.

Vultures, because of their food habit, act as a natural cleanser of the environment. But with reduced number of vultures, disposing of dead body has become a problem. Also, they are a competitor to the feral dogs. But with less number of vultures, the population of feral dogs is rising rapidly leading to rise in incidence of rabies. The chief suspect behind this mayhem is the Non – Steroidal Anti-Inflammatory Drugs (NSAIDs), Diclofenac which compared to other NSAIDs is cheaper and hence widely used for treatment of livestock. Vultures which feed on dead bodies of livestock earlier treated with Diclofenac are believed to suffer from diseases like Kidney failure, Drooping Neck Syndrome and Avian Malaria.This Diclofenac is one of the major reasons for unknown deaths of vultures. Ofcourse, Diclofenac is banned. Ofcourse it is widely used; as said, it is cheaper than its safer counterparts.

Also, cutting of trees, specially the Ficus (peepal) tree and Shimalu trees, which are the favourite nesting sites of this bird, has also affected its population. The sadder story is that these trees are cut down mostly because vultures nest on them and the superstitious local people want to get rid of this ‘dirty” and “unlucky” bird. The irony is that because of people’s superstitions, not only the vultures but economically and ecologically valuable trees also suffer. Irony does not end here. Earlier, people used to leave dead animals in open fields for vultures to eat them. But with decline in vulture population, to avoid foul smell, people now prefer to bury dead animals. Thus the remaining vulture population is left with scarcity of food, leading to their further decline!

But are vultures actually dirty birds? Because vultures live on carcasses, many of us regard it as a big, old, dirty bird. But we cannot be more wrong! If we notice, we will find that most vultures have almost no hair on their head. So though their head often gets smeared with blood etc. of the carcasses they eat, one or two dip in the nearby pond is enough to make their bald head as clean as ever. They are not just clean birds; these birds also keep our vicinity clean! But we human beings are always slow at understanding others help!

Innovative “vulture restaurants” are proposed to combat this food scarcity of vulture. These “restaurants” could be a part of a field near slaughter houses or some designated places where villagers may be asked to keep their dead animals instead of burying them. The first vulture restaurant was set up in South Africa in 1966. Maharashtra is to set up five vulture restaurant soon; one has already opened for its customers (http://articles.timesofindia.indiatimes.com/2012-01-25/nagpur/30662409_1_vulture-population-vulture-conservation-programme-vulture-species ).

We can do so many things. Stop using dicofenac. Start captive breeding of vulture; it can be quite successful (http://articles.timesofindia.indiatimes.com/2012-05-29/flora-fauna/31887551_1_vulture-population-vibhu-prakash-diclofenac). Start disposing the dead bodies of livestock in the open. Stop cutting down the nesting trees of vultures. And those, on whom reasoning do not work, they may just care to remember that Jatayu, who once helped Rama in the rescue of Sita, was but the king of vulture. Can we have a bit more reverence for this divine bird please?

Why Some Gases Are Deadly Dangerous – Ground Level Ozone

The last post asked what we’d do if we had to make a choice between the environment and some of our life giving activities. It is a tough choice to make. At a certain point in time will we have to make that choice? Not if we modify our activities to benefit both – us and the environment.

This article tells us why certain gases like ground level ozone are deadly dangerous for our health. It helps us understand why these gases shouldn’t be the end product of our activities.

Ground level ozone shouldn’t be confused with stratospheric ozone which is a protective layer of ozone. 

Stratospheric (or Protective) Ozone

Ozone or O3 is naturally present in the stratosphere – high above the earth. This ozone layer acts like a shield and prevents dangerous parts of UV light from the sun to reach the Earth. This ozone layer is highly desirable. It is the beneficial layer of ozone. Unfortunately, due to human activities, the ozone in our stratosphere is getting depleted.

In New Zealand, they inform us there is a hole in the ozone layer and we are advised daily that “burn time” is so many minutes (this number varies). This means that we should remain in the sun only for that many minutes, say seventeen minutes, and then move into the shade. We are constantly advised to slap on “sun block”, wear hats, thin long sleeves in summer and take precautions so that we aren’t exposed to the dangerous parts of UV light from the sun.

There is a high risk of skin cancer in places whose ozone layer has been depleted by human activity. The harmful UV rays could also give us cataract, impaired immune systems, destroy plants and plankton which is food for marine life and the most effective carbon absorber on planet Earth.

Which Human Activities cause ozone depletion in the Stratosphere?

Ozone-depleting agents are used in coolants, foaming agents, fire extinguishers, solvents, and aerosols. It sometimes takes these ozone-depleting chemicals years to reach the stratosphere. Substances released into the air today will contribute to ozone destruction well into the future. The main culprits are chlorine and bromine compounds.

One chlorine or bromine molecule can destroy 100,000 ozone molecules, so ozone is currently being destroyed much more quickly than nature can replace it.

Ground Level (or Dangerous) Ozone and Smog

The ozone that is dangerous to human health is ground level ozone. It is exactly the same chemical formula as stratospheric (or protective) ozone – O3. Yet, it is a major health hazard and a major constituent of photochemical smog.

Previously smog was a combination of just smoke and fog. Today smog is a chemical mixture of various gases and particulate matter (PM) that forms a brownish-yellow haze primarily over urban areas.

Nitrogen oxides and hydrocarbons (except methane) react in the presence of heat and sunlight to form ozone. It is a white haze that can be seen over many modern cities, especially the ones with sunny, warm, dry climates and a large number of motor vehicles. Because it travels with the wind, it can affect sparsely populated areas as well. It is close to the Earth in the troposphere and is called tropospheric ozone. This ozone is one component of smog.

It reacts with other components like sulphur dioxide, VOCs etc in various ways to form the brownish yellow haze, the modern day smog, that we see over so many cities with a poorly controlled environment. As the smog levels build, polluted air can be trapped and re-circulated for days so that car exhaust fumes are found in our atmosphere even when we aren’t driving.

Ground level ozone becomes a threat to the functioning of all living things after it reaches 82 ppb (parts per billion).

What are the effects of ground level ozone on our environment and health? 

Human exposure to ozone can produce shortness of breath and, over time, permanent lung damage. Research shows that ozone may be harmful at levels even lower than the current federal air standard Excessive ground level ozone can cause breathing problems, irritation, congestion, coughing, chest pain and swelling in the lungs. It triggers asthma. Even healthy adults and children get affected.

It affects the immune system. Many of the chemicals that cause ground-level ozone also contribute to other health effects, including cancer, and tissue and organ damage. High ozone concentrations also cause damage to the leaves of plants, resulting in the loss of agricultural crop yields and forest ecosystems.

Why Some Gases Are Deadly Dangerous – Particulate Matter

The last post asked what we’d do if we had to make a choice between the environment and some of our life giving activities. It is a tough choice to make. At a certain point in time will we have to make that choice? Not if we modify our activities to benefit both – us and the environment.

This article tells us what Particulate Matter or PM is and why it is deadly dangerous for our health. It helps us understand why it shouldn’t be the end product of our activities.

Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. The variety of PMs is huge.

  • Sulfates, nitrates, ammonia, sodium chloride, carbon, mineral-dust and water.
  • Dust, dirt, soot, smoke and liquid droplets directly emitted by factories, power plants, cars, construction activity, fires and natural windblown dust.

Sources of particulate matter can be manmade or natural. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray.

Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes (déjà vu?) also generate significant amounts of PM. Sulphur compounds react with other compounds in the atmosphere to form particulate matter or PM.

Why is the presence of PM dangerous to human health? 

PM affects more people than any other pollutant. These particulates penetrate deeply into sensitive parts of the lungs because they are easily inhaled and can cause or worsen respiratory disease, such as emphysema and bronchitis, and can aggravate existing heart disease by penetrating deep inside our arteries, leading to increased hospital admissions and even premature death. The smaller the PM, the greater its ability to penetrate deep inside our bodies.

Besides affecting our health PM can also

  • damage materials
  • clog stomata openings of plants and interfere with photosynthesis. This can stunt the growth of plants or even kill them.
  • contribute to acid rain formation.
  • form atmospheric haze that degrades visibility.

Some facts and figures that are a cause for concern:

  • The most concentrated PM pollution tends to be in densely populated metropolitan areas in developing countries.
  • The primary cause is the burning of fossil fuels by transportation and industrial sources.
  • Traffic exhaust is the single most serious preventable cause of heart attack in the general public.
  • Children, seniors, and individuals with pre-existing respiratory diseases are most susceptible to these health risks.
  • In developing countries, exposure to pollutants from indoor combustion of solid fuels on open fires or traditional stoves increases the risk of acute lower respiratory infections and associated mortality among young children.
  • Indoor air pollution from solid fuel use is also a major risk factor for chronic obstructive pulmonary disease and lung cancer among adults.
