Earth toDay

AS we speak, billions of people across the Earth are cooling heels at home, practicing own methods of social distancing based on their own understanding of the severity of the Coronavirus pandemic.

This unique situation imposed upon us by the potentially dangerous pathogen, proliferated by human excesses and abuse of nature, its resources and constituents or just stupidity. Now, whether it is man-made or nature’s gift is subject to speculation and various debates are on both scientifically and politically motivated. Whatever be the case, as on date 25+ lakh people are infected, ~7.5 lakh have recovered, and ~1 lakh have died, majority in the most powerful nation, the US followed by Europeans. All this mayhem in a just over 100 days since it was discovered in Wuhan, China, and ~80 days since WHO declared Covid-19 as a pandemic – the coronavirus has spread to every continent, except Antarctica, affecting 211 countries. Each country has reacted differently, few instructed with force, some advised its citizens to keep away from each other.

Social Distancing is the new normal. Covering up and practicing hygiene is not even an option any more.

World economy suffers terribly, Countries would lose Trillions, if not Zillions in trying to keep businesses afloat, to ensure people out of jobs are supported in some way, the poor and homeless would get food to eat – while fighting to keep the virus in check. The new Coronavirus isn’t as bad as it is made out to be – with an infection rate of 4k/ml in Spain to XX% and a death rate ranging between 13.3% in Italy to 0.56% in Iceland; common seasonal influenza virus claims 6.5 lakh people worldwide.

The rainbow in this worldwide storm: Nature, undisturbed by human activities and interventions, aided by countries under various stages of lockdown in the past month, is cleaning up, and the environment starts to feels fresh again. Rivers, flowing with urban wastewater for decades and declared dead, are now clean and water is fit to drink! Air pollution is at its lowest, with clear skies. Hopefully, once the virus’ imperious march stops in its tracks, humans will emerge healthy, fit and immune to Covid – and more importantly, very concerned to protect and improve the environment.

Meanwhile, the world is continuing to witness the impact of unsustainable and sometimes dangerous practices – vanishing rainforests and graveled hills, drying up lakes and under groundwater streams, polluted air- water-land, farming, (agri-poultry-aqua), soil degradation and beach erosion, ethnic tribes losing ancestral abodes, hundreds of species staring at extinction, dying bees and butterflies, man-wild conflict, unbridled change of land use, waste generation, unsegregated disposal and landfills, hoarding essentials, excess consumption, plastics manufacture, usage and unethical disposal, burgeoning cities scrambling to feed increasingly migrating labour and what not!

Is Coronavirus the catalyst that our Earth desperately needs, to mitigate centuries of misuse and exploitation, to rejuvenate?

The Arctic Ocean in summer will very likely be ice free before 2050, at least temporally, according to new research. A new study says a megadrought worse than anything known from recorded history is very likely in progress in the western United States and northern Mexico. Himalayan glaciers are melting faster than previously thought,

Actually, it could be worse. Powerful companies, from developed countries, impoverished with weeks of lockdown and Govts with economic inactivity in addition to sustaining their economies will look to rebuild on the rebound and capitalise the increasing demands of markets. Environment conservation and related budgets take a back seat, since in the short term the resources visible at hand are perceived to have improved. The climate could become even more degraded than it was in December 2019.

It will be challenging, as it has been over the years. Now, with the respite provided by Coronavirus, Govts could be influenced with concerted efforts by the society, combined with great political will, the environment can be further improved and clean climate can sustain. We must realise the and take advantage of this unexpected window of opportunity that has been provided to humankind.

On the 50th anniversary of the Earth Day, let us take the pledge to adopt sustainable lifestyle, adopt earth friendly products and practices,

Respect Nature, Plant native trees, Conserve water and energy, Buy local, Stop buying/using plastic, Use public transport or Car pool, Use renewable energy, Reduce dependency on fossil fuels, Build with sustainable materials.

Stay Home, Stay Healthy, Be Positive!

A new dawn for a cleaner greener future!

Indoor Air Quality

a note on how IAQ impacts health, immunity and COVID

  • The newCoronavirus has certainly had a worldwide impact.
  • It has become more important now to ensure higher levels of hygiene at our homes and offices.
  • Indoor air quality is directly correlated with respiratory health and immunity.
  • It has been documented that bad indoor air quality can enhance Covid-19 risk, especially among elderly and those with pre-existing respiratory problems.

Tips to improve Indoor Air Quality

Keeping it clean –

  • Avoid floor covering, if you have wall-to-wall carpets then vacuum once a week at least.
  • False ceilings, panel boards, plastic-plasters, etc., are dust traps; made of artificial gypsum, the heavy metals and chemicals that leach into the air can be troublesome, especially upper respiratory system..
  • Regular cleaning of bedding, sheets, drapes, cushions, is necessary; with pets at home, frequency may be increased.
  • Most window blinds, and furnishings, made of base plastic/synthetic fibers, are not desirable since they harm the earth and all living beings; bamboo / wooden chik blinds or furnishings of natural fibers may be used instead. These too must be dusted / vacuumed / washed periodically.
  • Clear the clutter. Items lying around gather dust and if left uncleaned will attract dust mites which affect the health. Dusting and wet cleaning once a while keeps mites away.

Aerosols –

  • Aerosol products come in many varieties – spray, deodorant, paint, e-cigarette, and cleaning liquids are just a few that release nanoparticles into the air.
  • Eliminating using such products can keep the air free of pollutants. Even if the air appears clear, tens of millions of air-suspended solid particles and liquid droplets get inhaled. Despite their minute size, they have major impact on our health and our climate.
  • Paints have volatile organic compounds that release toxins and particles of heavy metals into air by evaporation. Choosing products with zero VOC is one part, keeping indoors naturally ventilated is ideal.

Ventilation –

  • Improved ventilation, less mechanical more natural, is recommended to improve air quality.
  • Efficient buildings are oriented in right direction, designed to allow light and fresh air, cutting off heat. Natural ventilation.
  • Air-conditioners permit just 1/5th of fresh air per hour necessary for good health. Increased usage causes fatigue, breathing troubles, dehydrated skin and sinusitis. Filters and drip pans need periodical cleaning and replace when worn-out, which also improves product’s efficiency and energy management.
  • Air purifiers, and Dehumidifiers are effective, but consume energy and require frequent maintenance too.
  • Smoke particles get trapped into furniture, furnishings and indoor fabrics. Micro carbon and sulphuric compounds pollute indoor air causing cancer.

Houseplants –

  • Few Houseplants are considered beneficial in eradicating toxins and increasing oxygen indoors.
  • Plants should not be over-watered because constant damp soil could promote the growth of microorganisms which affect allergic individuals.
  • Sunning the plants periodically, keeps them healthy.

Pets –

  • Dander and fur too could affect air quality. Pets need to be cleaned regularly and rid of excess fur. Take care of their health which could affect overall IAQ.

Plug leaks –

  • Leaking appliances not only drip water, but also promote growth of mold and bacteria – which cause respiratory illnesses like asthma among others. Plug the leaks to promote life of the appliances and good health of self.

Natural ventilation improves air circulation and enhances indoor air quality by reducing indoor pollutants in all seasons. Graded vegetation (tall/medium/short trees, shrubs, creepers, climbers) outside the home is pleasing to the eye, invites a large amount of fauna; tall trees not only keep indoors cool but also mitigate pollution. Shaded windows too keep the summer heat away! (and that’s another topic, coming up)

Keeping doors and windows open as much as possible – is recommended to avoid immune inhibiting causes, that aids in fight against newCoronavirus as well – while washing hands regularly with soap and water, social distancing, and maintaining good personal hygiene are all added bonus to this end.

While this piece is being written, 9.5 lakh people are infected worldwide, increasing by the tens of thousands each day; 48k have succumbed, majority of them elderly and vulnerable with pre-existing health conditions (diabetes, heart, renal, asthma, high bp, etc). There is no known medicine yet, and a vaccine (though under human trials in many countries) is many months away. enhancing immunity or maintaining a good health is imperative to keep COVID-19 at bay. Eating whole-cooked vegetarian food does help, as does robust hygienic practices.

Prevention is best, immunity is the key
