Tony McMichael - Human Frontiers, Environments and DiseaseNo one has the full picture of the damage we're doing to our planet, says Debora MacKenzie. But we've never needed it more.
Everyone knows about the three blind men who investigated an elephant. Each came back sure the entire beast must be like the bit he had felt: the tail, the trunk, the leg. No one had the whole picture.
Humanity is now faced with an elephantine crisis of its own making made of bits that aren't always obviously related. Our physical domination of this planet is altering all our fundamental life-support systems. These are the processes that give us our food and water and air, our social stability, and ultimately our health. It's happening so fast and on such a scale that comprehending the whole process is almost impossible.
Scientists deal with this elephant in their methodical, piecemeal way, feeling their way around a collapsing fishery here, an emerging disease there, epidemics of obesity and starvation, climate change and population growth. And with each discovery comes yet another warning that something else that we do threatens us all, from driving cars to eating meat.
It's become fashionable to mock all this doom1 and destruction. If you don't realise that most of the problems are bits of the same enormous, onrushing elephant, it can seem as though the doomsayers are merely competing for attention and grant money.
But they aren't, as Tony McMichael's book tries to show us. There is enough in Human Frontiers, Environments and Disease to show that all these diverse warnings are not merely a trick to upset the optimists. They all stem from the same, huge fact: that having taken over the planet, we aren't running it in our collective best interests.
Perhaps we don't know what our best interests are. McMichael says we need to understand human ecology —our relationships with nature and the way we evolved— before we can know what makes for a healthy population.
To reach this comprehension, McMichael attempts to bring into focus a vast range of subjects, from hunter and gatherer2 diets to the history of germ theory. He even includes topics such as workplace safety and income3 distribution, social factors that can be crucial to health and to a global economy.
This brings into welcome perspective our obsession with free trade. Under current trade agreements, industries can compete by spending so little on wages and infrastructure, such as decent sewerage4, that their labourers end up in very poor health. The result: Guatemalan farm workers inadvertently contaminate New Yorkers' strawberries with a nasty intestinal pathogen.
This should turn the battle for minimum work conditions in trade agreements into intelligent self-interest. But this is a fact even epidemiologists usually forget.
Sometimes McMichael manages to pull things together —how trade, migration, poverty and dirty water spread cholera, for instance. And he knows a lot. The book is worth reading if only to learn more about these important, yet little taught subjects.
