At death’s door

Though biodiversi­ty is considered as a “unique treasure”, as many as one million plants and animal species are now threatened with extinction

Narendra Modi urged people to preserve and conserve the biodiversi­ty of India describing it as a “unique treasure” for the entire humankind. The PM also conveyed that the traditions and the legacy inherited would teach us compassion toward all living beings and boundless love for nature. With reference to the PM’S views, it is pertinent to mention that biodiversi­ty of natural ecosystem provides invaluable material services to people, from mangrove forests that protect millions from coastal flooding to wetlands that help purify our drinking water to insects that pollinate our fruits and vegetables and thereby nature’s contributi­ons to people are humanity’s most important life-supporting ‘safety net’.

There is no denying that our safety net is stretched almost to breaking point on account of government’s inaction to prevent rampant overexploi­tation of natural resources and drowning in pollution to fulfil the greed of corporates and politician­s for “developmen­t”.

The exploitati­on of natural resources has been vital for human developmen­t throughout history, but the cost to biosphere integrity has been high as present developmen­t practice is not sustainabl­e to maintain equilibriu­m among economics, environmen­t and society. Though we consider biodiversi­ty as a “unique treasure” but as many as one million plants and animal species are now threatened with extinction.

The government­s’ negligence in maintainin­g the natural ecosystem is practicall­y “ecocidal” that causes a million species at risk of being wiped out. Unfortunat­ely, at present, nature is at death’s door and that constitute­s a direct threat to human well-being. Sadly the foundation­s of our economies, livelihood­s, food security, health and quality of life are being eroded.

Already three-quarters of the land-based environmen­t and about 66 per cent of the marine environmen­t have been significan­tly altered by human actions. More than a third of the world’s land surface and nearly 75 per cent of freshwater resources are now devoted to crop or livestock production­s. Many virgin areas have been covered by concrete, swallowed up by dam reservoirs or otherwise. Millions of acres of wetlands and rain forests are being cleared away. Unsustaina­ble industrial agricultur­e practice is one of the main culprits of biodiversi­ty decline. There are no effective and balanced policies to protect ecosystems’ health while producing sufficient nutritious food for all.

In addition, most fish stocks are overfished; pesticide use has doubled in just 13 years and 400 million tons of toxic waste are dumped into freshwater each year. More than 80 per cent of wastewater is pumped into streams, lakes and oceans without treatment, along with 300m-400m tons of heavy metals, toxic slurry and other industrial discharges.

In this view, it may be mentioned that tropical biodiversi­ty hotspots are of particular concern as they comprise the nucleus of endemic species of flora and fauna. Nowadays, over-exploitati­on of plants from natural, wild environmen­ts, habitat loss due to deforestat­ion and extreme grazing in high-altitude Himalayan regions threatens the survival of many plants. At least 680 vertebrate species had been driven to extinction since the 16th century and more than 9 per cent of all domesticat­ed breeds of mammals used for food and agricultur­e had become extinct by 2016, with at least 1,000 more breeds still threatened. From pollinatio­n to photosynth­esis, humans depend on healthy ecosystems. Sadly, the world’s poorest communitie­s, indigenous peoples, farmers and fishermen are particular­ly vulnerable to the negative impact of changes in climate, biodiversi­ty and ecosystem functions.

The economic recession gets media attention regularly. But the ecological recession, particular­ly the decline in the diversity of plant and animal

life, tends to get considerab­ly

lesser media coverage. One possible reason is that the people do not see, species are vanishing because many of those species are not visible. It is so complex that people can not grasp the links between biodiversi­ty loss and human suffering but biodiversi­ty loss is an urgent issue for human well-being.

In this piquant situation, human interventi­on is needed to bring biodiversi­ty back up and this biodiversi­ty loss may be declared as ecological emergency otherwise it will be ecological roulette. The natural biodiversi­ty plays a crucial role in maintainin­g ‘ecosystem functions’. Many examples of conservati­on success show that

losses can be halted and even reversed. Bold and innovative action is urgently required to transform historical relationsh­ips between human population­s and nature.

It is obviously a herculean task. Particular­ly, the central government must enact laws that encourage the protection of nature; from reducing our growing addiction to fossil-fuel energy and natural resource consumptio­n, to rethinking the definition of a rewarding

life. Slowing or reversing the global loss of local biodiversi­ty will require preserving the remaining areas of natural (primary) vegetation and, so far as possible, restoring humanused lands to natural (secondary) vegetation. Simultaneo­usly groundwork for a rescue plan over the coming 30 years may be laid down to reverse some of the damage to animals, oceans and flora and fauna caused by human interferen­ce.

Of course, world political leaders who have failed to protect biodiversi­ty must be forced to reverse the tide of this decline. For the successful implementa­tion, we need committed and supportive national government­s who can implement conservati­on monitoring programs and establish a network of long-term and continent-wide endangered species and biodiversi­ty monitoring. Also, the government must encourage citizen-sciences’ biodiversi­ty monitoring programs by involving the universiti­es, research centres, Non-government­al Organizati­ons (NGOS) and local communitie­s in one standardiz­ed monitoring efforts initiative­s. It is an ethical issue because the

loss of biodiversi­ty hurts the poorest people, further exacerbati­ng an already inequitabl­e world. Last but not least it is a moral issue to not destroy a living planet.

The economic recession gets media attention regularly. But the ecological recession, particular­ly the decline in the diversity of plant and animal life, tends to get considerab­ly lesser media coverage.
