The Bioremediation Imperative
In 2009, a team of scientists from around the world came together to create what they called a ‘Planetary Boundaries Framework.’
This framework identified nine processes that must be monitored to maintain life on Earth, including ozone depletion, biodiversity loss, chemical pollution, climate change, ocean acidification, freshwater composition, land systems change, nitrogen and phosphorus flows, and atmospheric aerosol loading.
Crossing the recommended thresholds for any of these processes could result in abrupt and possibly irreversible environmental changes.
We have already exceeded the safe threshold for four of these boundaries, researchers say.
The rate and scale at which we are degrading the planet have been unprecedented in the last 10,000 years.
Most people see environmental issues as something that happens in another dimension.
Most think we can stop and remedy the situation at any time.
The crisis is not looming large, ready to explode into a doomsday scenario, but the hysterical imaginings of a few.
This study, however, reveals that the problems are not linear, as most people tend to perceive them.
If we inflict enough damage on our planet, we risk shifting it to a whole new state, and the damage spirals out of control in an irreversible multi-scenario domino effect.
Our environment, the food we consume, and our general health are all directly correlated.
We can’t protect one without also protecting the other two.
Conversely, if we don’t protect one, we are also harming the other two.
As individuals, communities, and economies, we each have a responsibility to protect and safeguard life as we know it for future generations.
When it comes to matters like the environment, we humans tend to react rather than take action.
As individuals, we can all do our bit: we can recycle, carpool, or use public transport, reduce our carbon footprint, and compost food waste.
Not so difficult to implement if there is a will.
Within our communities and economies, we face the more substantial challenge of building consensus around affirmative environmental action and the imperative to combat apathy.
Even if we can build consensus at all levels, the damage to our environment has crossed the threshold where it is possible to reverse without intervention.

Common intervention techniques, such as burning, incineration, burial, and landfill dumping, are expensive to implement and have a significant environmental impact.
In most cases, they do not even solve the problem but compound it by merely delaying the inevitable.
The solution is bioremediation, a technique as old as time.
Bioremediation is a process used to treat contaminated media, including water, soil, and subsurface material, by altering environmental conditions to stimulate the growth of microorganisms and degrade the target pollutants.
Simply put, bioremediation is the use of either naturally occurring or deliberately introduced microorganisms to consume and break down environmental pollutants, thereby cleaning a polluted site.
Bioremediation employs microbial technology. The first lifeform on Earth, microbes, are essential to life.
They have always broken down waste, and humans have always used them, whether knowingly or unknowingly, in agricultural, domestic, and industrial activities.
They can protect crops, promote sustainable farming, and treat wastewater. Nothing is a challenge for these microscopic powerhouses.
Environmental regulations are increasingly making bioremediation the preferred intervention.
It is also a cost-effective solution without unfavourable implications on the environment.
In most cases, it provides a more permanent solution.
Several successful, large-scale projects have utilized bioremediation to mitigate ecosystem damage.
These include the cleanup of the Ganga at 52 sites using ‘sewage-eating microbes’ or the treatment of sludge from last year’s Chennai oil spill.
Many companies are seeking to innovate solutions to stem, if not reverse, the tide of environmental damage.
One such company on the cutting edge of remedial innovation is VolkerWessels’ subsidiary, KWS, which, in 2015, introduced a unique concept for building plastic roads as a sustainable alternative to traditional asphalt roads.
The PlasticRoad concept involves recycling plastic waste into lightweight modules with hollow interiors that can be fitted with cables and plastic pipes, allowing excess water to drain.
Bioremediation is the most sustainable alternative and by far the most promising solution to the environmental degradation time bomb.
They say we don’t inherit the earth but borrow it from future generations.
It is imperative, therefore, that we act now to repay this debt in the future.
