Restoration of Ecological Community Kate Rawles ‘There is no more urgent intellectual task facing the human species… than thoroughly to reimagine its relationship with nature.’ Robert Macfarlane I’m on the Sea Dragon, a 72-ft yacht en route from England to the Azores. We’re about to lower a couple of fish-mouthed trawls into the grey waves. There, they will funnel sea water into glass jars at their base. We haven’t seen land for days. Yet after each brief daily trawl, alongside the writhing plankton, tiny pieces of plastic float in the glass. From above the waves, the vast and ever-shifting mass of the sea often looks just fine. It isn’t. Plastic has pervaded the ocean. Even from a ship, the ocean can be a powerful provider of that strangely positive feeling that comes with suddenly understanding yourself to be a tiny irrelevant being in the vastness of nature. Individually we are specks on the ocean. But collectively, for the first time in the history of humans on Earth, we have become gargantuan. Our impacts on nature are staggering, immense, decimating and global. Half the world’s tropical and temperate rainforests are now gone. Deforestation in the tropics continues at about an acre per second. Half the wetlands and a third of the mangroves are gone. 75 percent of the world’s fisheries are overfished. Wild species are disappearing about 1000 times faster than the normal rate and the latest estimates strongly suggest we’ve underestimated species loss so far, upgrading our current impact on mammals, birds, amphibians and reptiles to a staggering 50 percent lost since 1970. The sixth great extinction is being caused, uniquely, by a resident species. We’re altering the composition of the atmosphere, conducting an immense experiment on our climate. Our cumulative impacts on Earth are now so great that geologists are debating whether to rename the current era ‘Anthropocene’. The human era. It’s not a compliment. Our ways of life are, collectively, utterly unsustainable. If everyone on Earth enjoyed the lifestyle of an average Western European, by 2050 we would need three planets. ❙ 69
