While we marvel at Nasa’s discoveries, we destroy our irreplaceable natural resources – so we can buy pre-peeled bananas and smartphones for dogs
Evidence for flowing water on Mars: this opens up the possibility of life, of wonders we cannot begin to imagine. Its discovery is an astonishing achievement. Meanwhile, Martian scientists continue their search for intelligent life on Earth.
We may be captivated by the thought of organisms on another planet, but we seem to have lost interest in our own. The Oxford Junior Dictionary has been excising the waymarks of the living world. Adders, blackberries, bluebells, conkers, holly, magpies, minnows, otters, primroses, thrushes, weasels and wrens are now surplus to requirements.
In the past four decades, the world has lost 50% of its vertebrate wildlife. But across the latter half of this period, there has been a steep decline in media coverage. In 2014, according to a study at Cardiff University, there were as many news stories broadcast by the BBC and ITV about Madeleine McCann (who went missing in 2007) as there were about the entire range of environmental issues.
Think of what would change if we valued terrestrial water as much as we value the possibility of water on Mars. Only 3% of the water on this planet is fresh; and of that, two-thirds is frozen. Yet we lay waste to the accessible portion. Sixty per cent of the water used in farming is needlessly piddled away by careless irrigation. Rivers, lakes and aquifers are sucked dry, while what remains is often so contaminated that it threatens the lives of those who drink it. In the UK, domestic demand is such that the upper reaches of many rivers disappear during the summer. Yet still we install clunky old toilets and showers that gush like waterfalls.
