Answer:

Natural capital is everything nature provides us for free. It is what our economy is built upon. We add man-made capital in the shape of houses, factories, offices and physical infrastructure, and human capital with our skills, ideas and science.

Natural capital should, therefore, be at the heart of economics and economic policy – but it isn’t. As a consequence we abuse nature, drive species to extinction, and destroy ecosystems and habitats without much thought to the consequences. The damage won’t go away; as we wipe out perhaps half the species on the planet this century and induce significant climate change, the economic growth we take for granted will be seriously impaired. Put simply, our disregard for natural capital is unsustainable – it will not be sustained.

Just as we try to maintain and enhance our own assets – our houses, cars and our knowledge and skills – so too should the broader economy avoid running down its base of natural capital assets. Some natural assets will be used up – such as the non-renewables like North Sea oil and gas – but even here we should be mindful of compensating future generations for what we will not therefore bequeath to them.

The natural assets that really matter are the renewables – the ones nature keeps on providing us for free, forever – provided we don’t deplete them beyond the threshold of sustainable reproduction. We can for example carry on for hundreds of thousands of years harvesting herring from the North Sea, as long as we do not overfish them. The potential value of all those fish forever is enormous.

Think of some of the things you could do today. If your front garden is paved and concreted over, you could break it up and allow wild flowers to flourish, which in turn would help the bees. So barren is much intensive agricultural land , as it is sprayed with pesticides and herbicides and its soils supplemented with nitrogen fertilisers, that bees often find cities much better habitats than the countryside. You could put away the slug pellets and the weed killer.

Explanation:

   et we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit.

   The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled.

   Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.

Medicine: Nature is our greatest medicine cabinet: to date it has provided humankind with a multitude of life-saving medicines from quinine to aspirin, and from morphine to numerous cancer and HIV-fighting drugs. There is no question that additionally important medications—perhaps even miracle cures—lie untapped in the world’s ecosystems. In fact, researchers estimate that less than 1% of the world’s known species have been fully examined for their medicinal value. However the ecosystems that have yielded some of the world’s most important and promising drugs—such as rainforests, peat swamps, and coral reefs—are also among the most endangered. Preserving ecosystems and species today may benefit, or even save, millions of lives tomorrow.

Fisheries: Humankind has turned to the rivers and seas for food for at least 40,000 years but probably even longer. Today, amid concern of a global fishery collapse, more than a billion people depend on fish as their primary source of protein, many of them among the global poor. Fisheries also provide livelihoods, both directly and indirectly, for around half a billion. Coral reefs, mangroves, and seagrass ecosystems provide nurseries for the world’s fisheries, while the open ocean is used for migrating routes and hunting.

Even with the direct importance of the world’s fisheries for food, stewardship has been lacking, allowing many populations to drop precipitously and still permitting ecologically destructive fishing. While the world’s fisheries are primarily threatened by overfishing, including bycatch, marine pollution is also a major problem.
