Live a personal life appropriate for an age of climate change: fly as little as possible (one person’s trip to New York is the equivalent of leaving a 1kw electric fire on 24 hours a day for a year).  But that doesn’t mean not flying at all.  A very occasional  trip to Australia won’t bring about the end of the world. And a solar plane has already flown round the world.  It’s hard to imagine a jumbo jet fuelled by solar power.  But lighter planes might well be, given enough research and investment.  Help to create the climate of opinion which is urgently determined to see that happens.

Eat less meat – that doesn’t necessarily mean eating no meat. Cattle fed on grass produce less methane and long established meadows store carbon. It’s industrially produced milk and meat that we should avoid. Consider being a vegan. In a world already short of food it takes 12 times less land and water to produce the same nourishment as it does if the nourishment comes from animals (though don’t forget the important part animal manure plays in organic husbandry). Go organic. Of all the shocking statistics, agronomists forecast that at present rates of soil erosion most of the earth’s topsoil will have been lost within sixty years.

Drive as low an emissions car as possible. Reuse and recycle.

For a long time now the default social principle has been to make society as wealthy as possible. We need to change that attitude.   Instead we need to put love and concern for the earth and all the creatures and people in it as our principle inspiration for life. We cannot afford to let Bangladesh go under water. If it does so eventually Norfolk will too. We need to realise how deeply connected we are to every person and every creature on earth.   At present rates of extinction millions of beautiful species that took millions of years to evolve will disappear between now and the end of this century because of human activity. How can we let that happen on our watch?

Above all, cultivate determination and optimism. We can beat this. Let’s not just lie down and die as we will if the politicians don’t do more. Once we can halt carbon emissions there are new technologies that will help us to support a world of even 10 billion people – electric and eventually hydrogen cars, artificial bacteria, lab cultured meat, hydroponic vegetables grown in tower blocks in cities. Above all we want you to feel the excitement of moving into a new and better post-fossil fuel age. But to do it we have to get out of fossil fuels. Let’s do it. Let’s go all-out. Let’s save the earth for our children.
