Deadly Climate Change Impact On Human Health: How Prepared Is India?

It’s not uncommon to find many people, including heads of countries, expressing their serious apprehensions in public, about the scary impact of climate change. Just the last year, on November 26, 2018, BBC News captured one of such incidences with the astonishing headline: “Trump on climate change report: I don’t believe it.” The findings of this report have underscored, ‘unchecked global warming would wreak havoc on the US economy.’

Similarly, a few years ago, on September 05, 2014,CNN News 18 quoted Prime Minister Narendra Modi as saying: “Climate has not changed. We have changed. Our habits have changed,’ while answering to a question on climate change. Regardless of the outcome of any split-hair analysis of the rationale behind such statements from the world leaders, such public discourse could trivialize the possible catastrophic impact of climate change on the planet earth.

Be that as it may, that climate change is taking place, carrying all its ill-effects, is real now, without any ambiguity. There is also widespread consensus among the members of the United Nations that ‘the Earth is warming at a rate unprecedented during post hunter-gatherer human existence.’

It is worth noting that way back in 2001, the ‘Third Assessment Report of the Intergovernmental Panel on Climate Change’, further recorded: “There is new and stronger evidence that most of the warming observed over the last 50 years is likely to be attributable to human activities”, most importantly the release of greenhouse gases from fossil fuels.

Several ‘International Agreements’, including the Paris Agreement on Climate Change - all supported by hard scientific data, have called for immediate, quantifiable measures in each country to address the ‘wide-ranging environmental threats, such as ozone depletion and long-range transboundary air pollution.’ Against this backdrop, in this article, I shall focus on the dreadful effect of climate change in the proliferation of a wide-variety of ailments, especially infectious diseases, within a few decades. While doing so, let me first have a quick recap on what is ‘Climate Change’, in a simple language.

Climate Change – a quick recap:

According to the United Nations, ‘Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.’

It’s important to note, although, the planet Earth’s climate is constantly changing over geological time, the current period of warming is occurring more rapidly than many past events. Scientists are concerned that the natural fluctuation or variance, is being overtaken by a rapid human-induced warming, as they emit more greenhouse gases. As these gases get trapped in the atmosphere, more heat is retained that has serious implications for the stability of the planet’s climate, even impacting human health with grave consequences. The World Health Organization (W.H.O) has also warned that the health of millions could be threatened by increases in malaria, waterborne disease and malnutrition.

Its impact human health:

The direct and indirect impact of climate change on human health is profound. Before I go into the specifics, let me indicate some of the direct ones, as captured by the Center for Health and the Global Environment (CHanGE), University of Washington. This is sans any charts and maps, unlike the usual practice:

  • Increasing temperatures are causing poor air quality that can affect the heart and worsen cardiovascular disease.
  • Increasing exposure to pollen, molds, and air pollution, all of which can worsen allergies and other lung diseases, such as asthma.
  • Changes in the geographic range of disease-carrying insects, such as mosquitoes, ticks, fleas and other similar ones, which can fast spread many tropical ailments, such as dengue fever and malaria to humans.
  • Increasing frequency and severity of extreme weather and climate events can cause, besides many physical illnesses, several kinds of mental illnesses – increasing both morbidity and mortality.
  • Frequent flooding events and sea level rise can contaminate water with harmful pathogens and chemicals, potentially causing food-borne and waterborne illnesses.
  • Changing weather patterns affect the quality and quantity of nutritious foods with increasing incidence of under-nutrition and micronutrient deficiencies.
  • Additional stress placed on hospital and public health systems, could limit people’s ability to obtain adequate health care during extreme weather events and disease outbreaks.

Most specific and the deadly one:

The World Health Organization (W.H.O) publication - ‘Climate change and human health – Risks and Responses,’ clearly flagged that ‘Changes in infectious disease transmission patterns are a likely major consequence of climate change.’

Citing a pertinent analogy to explain the reason, it said: “Humans have known that climatic conditions affect epidemic diseases from long before the role of infectious agents was discovered, late in the nineteenth century. Roman aristocrats retreated to hill resorts each summer to avoid malaria. South Asians learnt early that, in high summer, strongly curried foods were less likely to cause diarrhea.”

Would pharma players convert these problems into opportunities?

Curiously, some pharmaceutical investors are researching to fathom potential business opportunities lying underneath the above problem, especially for vaccines and newer antimicrobials. It’s probably a blessing in disguise not just for the drug companies, but also for the general public, considering the following two issues, prevailing in the current scenario:

  • According to W.H.O, Antimicrobial Resistance (AMR) is an increasingly serious threat to global public health. It threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi, causing the success of even major surgery and cancer chemotherapy seriously compromised.
  • ‘Pharmaceutical companies are backing away from a growing threat that could kill 10 million people a year by 2050’, reported a July 19, 2018 article. This is because, ‘Antibiotics Aren’t Profitable Enough for Big Pharma to Make More,’ wrote another article, published in Bloomberg Businessweek, on May 3, 2019.

Interestingly, a recent report analyzed and evaluated how this can be done, and which companies will be benefitted most in that process. 

“Climate change to fetch a big business opportunity for pharma”:

As reported on July 25, 2019, Morgan Stanley told investors that climate change will cause an increased prevalence and rapid spread of infectious diseases that may be a boon for some drug companies with big vaccine portfolios. It also highlighted, between 383 million and 725 million more people may be exposed to Zika, dengue and other diseases by 2050, depending on the pace and severity of global warming.

The analysts estimated, especially 7 pharma companies will be critical to fighting infectious diseases brought on by climate change. According to the research note of thebank, ‘the USD 500 billion infectious disease market could see demand for an added USD 125 billion in new vaccines, or as much as USD 200 billion assuming premium pricing for more complex new treatments.’

The top possible gainers:

Identifying the top possible gainers, Morgan Stanley apprised, vaccine development being more difficult and expensive, companies that are already in that business will have an upper hand.

Hence, Sanofi and GlaxoSmithKline are expected at the top, given their existing pipelines and manufacturing capacity. Takeda and Merck both have vaccines in the works for dengue fever, one of the diseases that climate change is likely to exacerbate. Janssen and Pfizer are both active in the vaccines market, but would need to establish new research programs to take on tropical diseases. ‘Moderna’ is also in a good position because it has demonstrated a potential pipeline for drugs combating the Zika virus., as Morgan Stanley further elaborated.

Nevertheless, Morgan Stanley isn’t the only bank looking at investment opportunities from climate change, on July 24, 2019, Goldman Sachs also, reportedly, said it was hiring a sustainable-finance group that is looking into issues related to sustainability. Thus, on the positive side, climate change could fetch a big business opportunity for many pharma players, across the world.

600 million people at risk for climate change in India:

On June 24, 2019, a reputed national business news daily of India reported, “600 million people at risk: Climate change may soon turn critical in India.” Against this threat, the current public health care infrastructure in the country, continues to remain fragile, as stated in India’s National Health Profile, 13th Issue.

It also states, the cost of treatment has been on the rise in India and it has led to inequity in access to health care services. Intriguingly, the country spends around 1.02 percent of its GDP towards public health, which has remained static to declining over a long period of time. Although, health insurance is a growing segment, it hasn’t taken off fully. Several measures are needed to improve and expand insurance coverage.

Further, according to the report by the Center for Disease Dynamics, Economics & Policy (CDDEP) in the US, India is facing shortage of 600,000 doctors and 2 million nurses. This report was widely quoted by the Indian media, on April 14, 2019.

These facts give a perspective on what is India’s level of preparedness to address the critical health issues related to climate change, especially the havoc that the dreaded infectious diseases can cause to so many.

Conclusion:

Astute health policy makers, including a large section of the top political echelon of the country are, apparently, aware of various ill effects of climate change. They also seem to be cognizant that these are likely to accelerate the worsening health problems of the population, including infectious diseases, asthma and other respiratory diseases.

Assuming, new and modern drugs will keep coming to help treat these ailments, do we have a functioning and efficient public health infrastructure to grapple with such issues. What about high out of pocket expenditure towards healthcare for a large section of the population, regardless of Ayushman Bharat?

As the (W.H.O) publication - ‘Climate change and human health – Risks and Responses’ recommended, ‘early planning for health is essential to reduce, hopefully avoid, near future and long-term health impacts of global climate change. The optimal solution, however, is in the hands of governments, society and every individual—a commitment to a change in values, to enable a full transition to sustainable development.’

That said, as India is also a signatory to the latest Paris Agreement on Climate Change, can we assume, India will walk the talk to significantly contain its deadly impact on human health? How is India preparing itself to meet this great challenge of Probably it is anybody’s guess, at least, as on date?

Worsening Health Effect Of Climate Change In India: A Perspective

At present, out of the top five most pressing global and local environmental challenges, ‘Climate Change’ features at the top.

It has been broadly defined as, “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” 

The impact of Climate Change’ is so profound that, if not addressed immediately, it would most likely to cause extinction of human life from the planet Earth and that too in the most agonizing and painful way, lasting over a long period of time.

The Paris Summit and its objectives: 

To effectively address the ‘Climate Change’ issue, nearly 150 world leaders of 196 countries, including Prime Minister Modi, deliberated in the Paris summit earlier in December 2015. Their representatives and negotiators ultimately succeeded, at the fag end of the ‘Paris Summit’ to arrive at a global consensus for inking a new ‘Climate Change’ agreement.

Prior to this, a report titled, “Paris 2015: Getting a global agreement on climate change”, published in August, 2014 by the Green Alliance Trust, United Kingdom stated that the agreement, expected to be signed in this Paris summit should ensure a meaningful united global action on climate change, covering the following key points:

  • A strong legal framework and clear rules
  • A central role for equity
  • A long term approach
  • Public finance for adaptation and the low carbon transition
  • A framework for action on deforestation and land use

Experts opined that a strong deal will make a significant difference to the ability of individual countries to tackle climate change by ensuring the following:

  • Give a clear signal to business for desired environmental protection and pollution control
  • Guide investment toward low carbon outcomes
  • Create a simpler, more predictable framework for companies operating in different countries
  • Help meeting international development aims, which are at increasing risk from rising global temperatures.
  • Help reducing poverty
  • Help improving health and building security
  • Fetch huge benefits to the natural environment by helping to avoid biodiversity loss and the degradation of ecosystems upon which the existence of human life depends

India’s position on ‘Climate Change’:

India’s position on ‘Climate Change’ has been clear and is well captured in Prime Minister Modi’s reiteration in the Paris summit as follows:

“Climate change is not of our making. It is the result of global warming that came from an industrial age powered by fossil fuel. Yet, we face its consequences today, and that is why the outcome in Paris is so important and we are here today. We want the world to act with urgency. Agreement must lead us to restore balance between humanity and nature. We want a comprehensive equitable and durable agreement in Paris.”

Worsening health effect:

‘Climate Change’ could even drive the human race to extinction in its final outcome. Meanwhile, besides its devastated environmental impact on the planet Earth, it would gradually but surely worsen human health conditions.

In this article, I shall focus only on human health perspective on ‘Climate Change’. 

Direct and indirect health impact:

I would classify the adverse impact of ‘Climate Change’ on health basically into two categories:

- Indirect

- Direct

Indirect impact: 

Many of the indirect health impact events of ‘Climate Change’ either go unnoticed or are still considered as an ‘Act of God’. Although this issue relates to our ultimate survival, even today in India not many debates are taking place on the subject, mostly in the Television Channels. This amazing medium continues to remain obsessed with competitive high decibel shouting and slanging matches to strengthen the viewers’ appetite, even more, mostly on trivial sensationalism.

Fortunately, global awareness of the disastrous impact of ‘Climate Change’ is increasing, slowly but surely. 

I shall give below just a few examples of indirect health impact of this change:

- Extreme weather events, such as floods, droughts, tsunamis, heat-waves and other disasters would keep increasing the mortality rate. Many experts attribute the cause of the recent deluge in Chennai to ‘Climate Change’, though there are other view points too. 

- Extreme weather conditions have also started causing frequent crop failures, especially in the developing world like India. As a result, many people go hungry and children suffer from malnourishment, mostly in rural areas, precipitating adverse health consequences.

- The impact of all these on mental health is also at times devastating and should in no way be ignored. Frequent incidences of farmers’ suicide in India due to crop failures could possibly be due to their deteriorating mental health, which needs to be studied in detail.

Direct impact:

According to ‘Big Picture’ – a free and impartial educational resource that explores the innovations and implications of cutting-edge science, rising temperatures and pollution levels may act together to directly worsen various health conditions, a few examples are as follows:

- Researches say, air temperature is more likely to affect cardiovascular function, when ozone levels are high, including the heart’s electrical activity and airflow into the lungs.

- A recent review has established that air pollution sets off nearly as many heart attacks as physical exertion, alcohol or coffee. Belgian researchers examined 36 studies conducted in various countries between January 1960 and January 2010 to examine the percentage of heart attacks attributable to the common risk factors and found that air pollution increased a person’s heart attack risk by 5 percent.

- Higher temperatures may also make the body more sensitive to toxins, such as ozone.   

- Studies show allergies are on the rise in developed countries, including the United States, which could partly be rising carbon dioxide levels and warming temperatures. 

- A number of notorious diseases, such as, malaria and cholera, thrive with the increase in temperature and rainfall. To give an example, the mosquitos that carry the malaria parasites grow rapidly in hot and humid conditions. The increasing prevalence of such weather conditions in climate change is likely to spread these diseases in a much wider population.

Is there any upside for ‘Climate Change’? 

Available information also points out towards some possible, but limited benefits for ‘Climate Change’, as follows: 

- Reduced risk of dying of the elderly persons from extreme cold in the winters of the temperate countries.

- Longer summers in those countries are likely to improve agricultural yields of the farmers.

Let me hasten to add, all these upsides, if at all, may not help the developing and poorer nations of the planet Earth, as such climatic conditions are mostly prevalent in the developed nations of the world.

Need for further research:

A report titled, “A Human Health Perspective On Climate Change”, published on April 22, 2010 by ‘Environmental Health Perspectives’ and the ‘National Institute of Environmental Health Sciences’, identified the following major research areas that need to be further explored and understood in the ‘Climate Change’ perspective:

The above outcome of the study is exactly in the expected line, which was “to identify research needs for all aspects of the research-to-decision making pathway that will help us understand and mitigate the health effects of climate change, as well as ensure that we choose the healthiest and most efficient approaches to climate change adaptation.”

How can we all contribute individually?

On this subject, by a release on November 26, 2011, ‘The National Aeronautics and Space Administration (NASA)’ of the United States recommended some very easy to follow steps for all of us.

It said, each individual can help in this matter by using less energy and water. For example, one may consider turning off lights and TVs when one leaves a room. Turn off the water, when brushing teeth.

It suggests, another way to help is by learning about Earth and its climate. The more we know about how Earth’s climate works, the more we shall be able to help solve problems related to climate change and that is also the purpose of this article.

In addition, besides many others, we may consider lesser use of our private cars and more of available public transports. Smokers may consider to quit smoking. We can also help by planting trees, which absorb carbon dioxide from the atmosphere.

India’s high stake:

A December 9, 2015 article published in ‘The New York Times’, titled “For Indians, Smog and Poverty Are Higher Priorities Than Talks in Paris” reiterated as follows:

At the climate talks in Paris, “few countries have so much at stake as India. For the last month, the front pages of major newspapers have been dominated by one environmental crisis after another: City-dwellers are up in arms about hazardous levels of air pollution, which has already damaged the lungs of about half of Delhi’s schoolchildren. And last month brought torrential rains and flooding in the southern city of Chennai, evoking the erratic weather that climate experts warn about.”

India’s consistent stand in various ‘Climate Change’ talks is drawing a fine balance between rapid development of the nation, with commensurate new job creation and health safety & environment. However, the apprehension that is being expressed now by many, whether that is feasible on the ground at all, for holistic measures in the right direction, with the adequate funds flow for the same.

Thus, the key concern of the Indian negotiators was, signing of any global agreement to support a strong climate regime, without requisite funding, could seriously impede India’s economic growth and development agenda. The developing nations, such as India, therefore, expect adequate and committed funding from the developed nations for generation of clean energy to drive inclusive economic prosperity of the respective emerging economies.

Developed nations still not quite on the same page?

The developed nations, even in the final text of the deal, do not seem to be quite on the same page, with firm financial commitments. As a result, a ‘Tug of War’ of objectives, as it were, surfaced in the final negotiation process – mainly between sustained economic development and stringent global measures with fund commitment to contain possible extinction of the human race in the world.

The impact of an effective implementation of the agreement is expected to last almost in perpetuity.

Conclusion:                                                                              

Finally, on the last Saturday, December 12, 2015 a new global deal to address the pressing issue of ‘Climate Change’, was agreed in Paris. Unquestionably, this is a critical step forward for all countries to save the planet Earth.

Intriguingly, the deal still does not provide for a binding commitment towards adequate funding by the developed countries, which is so essential for the developing nations to adopt clean and renewable energy to contain the devastating impact of the ‘Climate Change’.

Although, the agreement does talk about funding of US$ 100 billion a year from 2020 to 2025, this is not the legally binding part of the deal, as many people had expected.

In my view, if there is just one statesman who could be singled out for taking exemplary initiative to make the deal come through, it would be President Barack Obama of the United States. He spoke several times to the heads of the several developing nations, including India, China and Brazil, many times to iron out the differences till the last moment, for this key global issue – indeed a statesman par excellence, at least to me.

Be that as it may, the deal has now been inked, Indian Government also has expressed its satisfaction and happiness with the final text of the agreement. Still, a key question haunts: Would it produce the desired results, as expected? Well, that depends on how effectively and time bound manner the global commitments get translated into reality, with required fund flowing smoothly, to contain environmental disasters, leading to natural calamities and jeopardizing human health-safety.

Let’s all keep our finger crossed, as the saying goes, “The proof of the pudding is in the eating.”
