Does it seem that most of the world's news and opinion media are pro-corporate and religiously fundamentalist? Desperate to discredit the International Panel on Climate Change, for business and/or ideological reasons, many in the media are grasping at icicles. They wish to divert nature-lovers from attention to human effects on nature with a lot of hoopla about the speed with which Himalayan glaciers are or aren't receeding.
The IPCC consists of hundreds of scientists and reviews thousands of research papers, and as has been the case since science began, they aren't all going to agree with each other. Science moves ahead by challenging conclusions, by contesting data. It takes much work and study for Average Citizen to comprehend the science of climate change -- the geology, oceanography, climatology, paleontology, chemistry, evolutionary biology, epidemiology, botany -- but some of the public want one easy definitive formula that explains all, sort of like what religion provides. Otherwise, such people claim, they are being "tricked." Then, they demand that top science people should resign, the latest of the condemned being Dr R Pachauri, the IPCC's Chair.
Don't do it Dr. Pachauri! He tells BBC News that he doesn't intend to, and for that we should be grateful. Pachauri takes a big-picture view of global warming, looking at how humanity fits in with and affects the biosphere. He reminds even the "greens" who only want to talk about oil and cars that there is more to a sane response to global warming than simply driving less. Pachauri looks at our relationship with other animals, especially the ones we eat. For meat eating we create inhumane factory farm behemoths and tons of atmospheric methane, and we cut down climate-stabilizing forests so as to grow animal feed. Become vegetarian, says Dr. Pachauri! No wonder he has enemies - the ranching and slaughterhouse industries make a powerful lobby, and the public has been largely brainwashed into believing they would shrivel up and collapse without steaks and ham, even though obesity and heart disease are major health threats throughout the world.
Alongside of obesity, there is also starvation and lack of water. The planet's natural resources cannot feed and shelter the 6.8 billion people already here; how will it sustain another few billion by 2050? You cannot go very far into climate change data without realizing that all problems are worsened by one factor: the pressure of human overpopulation -- the 6.8 billion consuming, building, driving, flying, manufacturing people gobbling up resources and spewing out pollution. Persons and industries committed to the dream of endless growth do not want to look at this; it's much easier to discredit climate change research by fussing about glacier measurements of four years ago.
Looking at other animals gives us special insight into climate change. The more we take over their habitats for paving and building, industry, dams and factory farms, the fewer species and ecosystems there are room for. Yet it is through natural ecosystems that Earth's atmosphere is maintained and the planet balances itself as a dynamic self-adjusting whole.
The heartening thing is that in theory, all people have to do from now on is have only one child each -- that would mean one for every two and population would decrease exponentially. It would take only a couple of generations to cut our numbers in half and to reverse the damage of the past sixty post-war, late-industrial years. What would happen if there were three billion instead of almost seven billion people on Earth? And how would that affect other animals? To look at the health of animal species is to look at the health of plants, oceans, forest and grasslands and the environment as a whole, everything in nature being tied into a single dense and varied tapestry. Half as many humans would mean:
Fish stocks and coral reefs rebounding; the whales and seals once again finding enough to eat
Half as much wilderness space being sacrificed to farming (monoculture crops)
The rebounding of biodiversity
Half as many cattle, pigs and chickens tortured in factory farming (even fewer if people go vegetarian) and commensurately fewer rivers being polluted by animal wastes
Less natural landscape being paved over (i.e. going dead). Cities would shrink: park space expand, built-over areas be reclaimed for living species
Reforestation, which would secure water-retention in the soil and the cloud-forests: the reversal of desertification
The comeback of bird species that depend on forested or meadow land
The comeback of pollinators (bees, butterflies, birds) that would in turn increase the range and density of flowering plants
Fewer cars, trains, planes spewing exhaust and greenhouse gases into the atmosphere
Smaller airports, fewer runways, fewer birds killed by planes
Fewer goods being transported by exhaust-spewing trucks
Fewer goods being transported by freighters at sea -- the underwater world less filled with whale-killing engine noise and sonar
Less manufacturing required, so less mining tearing apart Earth's habitats for minerals
Less power needed for construction, industry and heating buildings: fewer rivers dammed, oil wells drilled, tankers spilling, forests clearcut, concrete produced (a major source of greenhouse gases), and nuclear plants built
No destruction of the ocean floor by deep sea mining and oil drilling
Fewer oil pipelines disturbing animal migration routes, fewer windmills killing birds
Smaller markets for trophy-hunting and fur: more wildlife survival
Less destruction of estuaries and shorelines by development
A shrinkage of harbours and reduction of attendant pollution
Less demand for bushmeat: elephants and our primate cousins might not go extinct, leaving us the only large primate on Earth
Less competition for ever-scarcer natural resources would create less occasion for war
Being able to de-militarize, nations could spend more money on health care and education of populations
Jobs of the Future:
Innovators and inventors, of technology to get rid of the Great Pacific Plastic Garbage Patch
Inventors of ways to get rid of overflowing landfills: recyclers of used (de)construction materials
Land reclamation biologists
Researchers: medical, pure sciences, psychology
Teachers: to train tomorrow's researchers and inventors
Medical practitioners of all types
Farmers
Artists, writers, musicians, performers
Tree planters en masse
Ecotourism operators
Eldercare workers
Bankers, diplomats, lawyers, service providers of all types, labourers
Philosophers, theologians, media people
Add your own career ideas -- this is just a broad-outline suggestion, and of course all depends on how the world economy would be managed and regulated. The point is that when animals benefit, humans benefit. Over-crowding is the common factor. Over half the human race already live in cities; in 2050 virtually all will. The planet's equatorial band may well be all desert, and the rest an endless city. Where will wildlife go? Crowding them out means crowding ourselves too. Wouldn't it be great not to have gridlocked freeways, long waits in hospital emergency rooms, overcrowded classrooms, residential neighbourhoods so dense a child can grow up without ever putting feet off pavement?
If population decreases, where will the jobs be, people often ask? As much wealth can be created, money circulated and talent nurtured by putting Earth's natural treasures back, as has been made by ripping them out. Our "footprint" has sickened, polluted and unbalanced the atmosphere, oceans and landscapes alike. Continuing population growth can only lead for the next generation to a humanity divided into warring camps of haves and have-nots, living without wild companions on a paved, artificial, poisoned, lifeless planet. How alone and desolate we will be. Reversing population growth could lead so elegantly to the opposite. What are we so afraid of?
