Each day unravels before me many reasons why environmental science continues to be interdisciplinary. The branch of science has got strong linkages not only with the natural science, but also with humanities and social sciences. Globalism, eco-writing, environmental laws… there is a long list of instances when there occurs a marriage between environmental science and other schools of knowledge. On the other hand, laws of the land, culture, customs, mindset of the people, new inventions, historic discoveries and technological revolutions – all continue to have due impact on our environment. 

I was just thinking of these in the wake of the current surge of epidemics. Morbidity of living organisms, in short, leads to the morbidity of the environment, too. Epidemics thwart our green dreams. Virtuous life is fostered only when members of a society is healthy and happy. Preaching about environment to a perished society won’t earn desirable results. 

With Ebola outbreak, epidemic has become a hotly debated subject world over. Epidemic means the spread of infectious disease to a large number of people or other livings within short period of time. A disease is called an epidemic if the affected population crosses the expected number of infected people in a particular area.  Ebola, HIV/AIDS, Avian bird flu, Malaria, Cholera, Plague, Meningitis etc are some of the examples.

Connection between epidemic and environment is intertwined. For example, according to World Health Organization, a number of manmade and natural environmental factors including water supply, sanitation facilities, food and climate change influence the chances and spreading of epidemics. In case of diarrheal outbreaks most of the time, improper environmental hygiene is the main curse.  In case of many of such epidemics like Malaria or Ebola, natural hosts or vectors play a major role in their spreading.  Climate change can either favour or suppress the spread of vectors. 

It is a well known truth that fruit bats of the Pteropodidae family are natural Ebola virus hosts. But isn’t it also a truth that when climate change, fertilizer prize and dire lack of irrigation together take a villains’ role, poor people cannot find any better food than bush meat? Any epidemic outbreak weakens the physical and mental strength of the workforce. When there is no healthy agricultural workforce, there would be a concomitant crop loss and income loss. Consequently, there will be poverty, famine and diseases. 

Epidemics of livestock and poultry have also proved decisive.  November 2014 avian influenza virus attack on ducks in my homeland, Kerala in India, was reported to have brought a loss of over Rs.125 million to farmers. Though the disease outbreak could be successfully controlled due to timely intervention of the authorities, the money lost is lost; the peace of mind gone is gone. Definitely, such times of havoc drain away one’s eco-friendly enthusiasm. The reason should not be different for some countries having high prevalence of HIV/AIDS to lag behind socioeconomic developments. 

For such epidemics like HIV/AIDS, usually the victims come under the young age groups, who constitute not only the main workforce but also the major actors for positive social change, environmental wisdom and so on. When young adults face such catastrophe, there would be consequent turmoil in economy, farming, land use and natural resource management. When life itself is eroding, who would care about soil erosion!  

At the lash of an epidemic, people are thrown to stiff poverty. Naturally, for their minimal sustenance, they start seeking some shortcuts to make money. Thus becoming rampant would be sale and consumption of charcoal, timber, fuel wood and wild fruits duly exploiting their proximate natural resources. 

When society’s establishments fail to provide timely attention, epidemic victims resort to traditional healers, who would tax indigenous plant species in the localities for medicine and income. As the exploitation crosses limits, such plants fall under threatened category. Some studies have even pointed to the increased use of timber for making coffins in most affected localities. Not only that, fake traditional healers could prove detrimental, too.

There were certain findings that HIV/AIDS patients think that their lifespan is shorter and hence there is no need for any commitment to the slogan, sustainable development. This underlines the need for social counseling for enhancing optimism among epidemic victims. Another finding is that premature deaths due to epidemics have stopped transfer of certain traditional knowledge about sustainable management of natural resources. 

Thus the issue is complex. When epidemics further mar the lives of the poor, how could they be eco-prudent? One thing is clear: wide gap exists in unraveling the intricate connections between epidemics, natural environment and its resources. But let’s not step an inch back in our struggle for the wellbeing of the environment to assure the wellbeing of its members; and vice versa.
