Humans exist because of nature and everything we have, everything we are comes from nature. Nature is important for our mental and spiritual health and well-being, our food supply, our wealth, our science and security. And yet political and business decisions, as well as many of our personal decisions, are taken treating nature as a ‘nice to have’.
The World Wildlife Fund has published its ‘2018 Living Planet Report on the state of the Earth’. Scientific research from across the world has contributed to the findings of this report and it all points in one direction – nature is vital for our existence.
Painkillers, treatment for heart conditions and high blood pressure and cancer cures are all inspired by wild species. The International Union for Conservation of Nature (IUCN) estimates that there are as many as 50,000 to 70,000 medicinal and aromatic plants used industrially. 70 per cent of new small molecule drugs introduced worldwide over the past 25 years have come from, or have been inspired by, a natural source.
Wild animals, plants, fungi and microbes have always underpinned human well-being. We can now see how intelligent nature is and through the process of biomimicry we hope to be able to copy nature’s processes to solve human problems such as those relating to resource efficiency and renewable energy. The tragedy is that we are destroying this intelligent source of life that is in fact that which keeps us alive.
We are beginning to understand that the indigenous communities that have long been persecuted to extinction or near extinction, hold a most valuable understanding that has a rich social, cultural and spiritual significance for us. The changing planetary conditions are being increasingly linked to socio-economic disruptions.
We are living through what is being called the Great Acceleration, a phenomenon that is unprecedented in the 4.5 billion years of Earth’s existence. This is a period in which one species, humanity, has an exploding population and an economic growth that is driving planetary change through the increased demand of energy, land and water. Since the 1800s global population has grown seven-fold to 7.6 billion and the global economy has increased 30-fold.
Such is the impact of the Great Acceleration that scientists are calling this the Anthropocene Age or the age of humans. We should realise that this Great Acceleration has only been possible because of nature. Without healthy natural systems we are like a car driving at an insane speed towards a brick wall.
In a recent paper published in the journal Nature, researchers have analysed that of the major threats to the 8,500 species on the IUCN Red List are overexploitation and agriculture that is driven by human consumption. Overexploitation is the politically correct term for ‘killed by humans’.
Invasive species introduced by human activity, pollution, dams, deliberate fires to clear forests and mining are other contributors to biodiversity loss. Our consumption of natural resources has gone up by 190 per cent in the past 50 years.
We are in a state of emergency and we should behave like we understand this
Wherever there is an exploitation of Earth’s resources we are destroying the ability of that particular ecosystem to renew itself. Moreover as the product of the exploitation is not consumed where it is manufactured, grown or extracted we are irreversibly harming a number of ecosystems along the supply chain.
For example massive deforestation is undertaken in order to make way for the soy and oil palms plantations. Soy and palm oil are used as ingredients in animal feed and processed foods that are distributed worldwide.
The WWF report talks of the use of technology and big data that should help us understand the impact and the remedies to biodiversity loss. We are really losing the plot here. We all know what we are doing wrong. The idea that we need to spend time collecting and collating data before we can act while we continue to destroy nature at an exponential rate is ludicrous and is the fruit of the mentality that has caused this tragedy in the first place.
We should stop burning fossil fuels and producing single-use plastic. We should cut our meat consumption by at least half. We should go out into the seas and oceans and get all that toxic plastic out. We should start massive reforestation and wild habitats restoration works. We should stop all hunting and trapping. We should deploy the military to safeguard and protect nature.
We should have fishing moratoriums on large portions of the oceans and seas so that marine life populations can recuperate, grow and thrive. This just for starters. We are in a state of emergency and we should behave like we understand this.
Temperate, tropical and boreal forests cover only 30 per cent of the Earth’s land area. Importantly, however, they are home to 80 per cent of the planet’s terrestrial species.
Habitat disruption in the form of forest fragmentation is a major threat to biodiversity. It is estimated that in 70 per cent of forest mass on Earth the forest edge can be found within a mean distance of less than one kilometre. This has a huge impact on the structure and quality of wildlife habitat. It hinders the ability of wildlife to move from one forest mass to another.
It has a massively negative effect on forest microclimate and water flow as well as on the ecological dynamics between the greater forest mass ecosystem’s open spaces.
There is a direct correlation between forest fragmentation and an increase in hunting and trapping, logging, fuel wood collection, exploitation of the forest for bushmeat and plants, for food and medicines. A recent assessment found that only a quarter of the land on earth is substantively free of any human activity. By 2050 this is expected to decline to one-tenth.
There is a harmful interaction between land degradation and poverty, between conflicts and human migration. Degraded lands bleed sediments and nutrients in rivers or exports windswept dust to distant locations. Land degradation is a big contributor to global warming.
Habitat loss is a key driver to the biodiversity losses that have now catastrophically snowballed into the sixth mass extinction of life in Earth’s history, this time around totally caused by humans.
The report plainly states that urgent coordinated local, national and international action is necessary to slow and reverse the pervasive undermining of the basis of life on Earth.
People have always cleared forest for food and farming and the harvesting of forest resources in order to sustain their livelihoods and local economy. With the advent of globalisation, however, the forest clearing processes have become industrial in order to satisfy global demand. Tropical forests in South America, sub-Saharan Africa and South East Asia are most under threat.
Between 2000 and 2010 commercial and local agriculture were responsible for 40 per cent and 33 per cent respectively of forest destruction in tropical and sub-tropical areas. The remaining 27 per cent of forest clearance was due to urban development, mining and roads, communication and telecommunication infrastructure expansion.
Forests are slowly but surely suffering death by a thousand cuts. In a few hundred years we have destroyed what has been millions of years in the making. We exist in a vast universe and the wholesale extinction of life on Earth will pass unnoticed – the fact is, ultimately, we are the biggest losers.
