Would Jesus vote green? II

As I mentioned back here, tonight I gave a talk titled 'Would Jesus vote green?' at a restaurant in Harbord. Over the next few days, I'll post the talk in a short series.
What has Jerusalem to do with Athens the Amazon?
Human beings are currently causing the greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago. If present trends continue one half of all species of life on earth will be extinct in less than 100 years. A total of 11,046 species of plants and animals are listed as presently threatened or endangered. Current extinction rates are estimated to be around 1,000 times the normal background extinction rate. Within 50 years, one-third of all land-based species could face extinction. According to the United Nations, 71-78 per cent of the world's fisheries are 'fully exploited', 'over exploited' or 'significantly depleted'. All wild seafood will have disappeared from the world's menus within 50 years if current trends in overfishing continue according to one of the most comprehensive studies of marine life. In just 60 years the Antarctic blue whale population fell from 220,000 to just 1,000. One-quarter of the Earth's bird species have been driven into extinction by human activities.

Somewhere between a third and a half of the land surface of the earth has been transformed by human action. More than half of the fresh water sources of the world are now put to use by human beings.

Ancient forests are home to around two-thirds of all plant and animal species found on land. More than 2,000 tropical forest plants have been identified by scientists as having anti-cancer properties. Less than one percent of the tropical rainforest species have been analyzed for their medicinal value. Nearly 90 percent of the 1.2 billion people living in extreme poverty worldwide depend on forests for their livelihoods. Yet 80 percent of the world’s ancient forests have already been either destroyed or degraded, and half of that has been in the last 30 years. An area the size of a football field of ancient forest is destroyed every two seconds. That’s an area bigger than France and Spain combined in the last ten years. At current rates, all tropical forests may be gone by the year 2090.

Demand for oil and energy resources from industrialized nations like China are expected to almost double by the year 2030. Two thirds of all energy generated in power stations is lost as waste heat – up the chimney and along transmission lines. The energy use per capita of high income countries is more than 10 times higher than that of low income countries. The world has a finite supply of oil. We are roughly halfway through using it. At some point within the next few years, it is likely that the rate of oil extraction will fall into decline. With ever-growing demand, once this point of ‘peak oil’ production is passed, prices are likely to rise rapidly, with possibly disasterous consequences for the global economy. For every kilojoule of energy we gain from eating food, we spend ten kilojoules of (mainly oil) energy to fertilise, harvest, transport, refrigerate and cook it. If we were to replace all fossil fuels with nuclear power, world uranium supplies would be depleted in four years.

More than one billion people lack access to safe drinking water, 2.6 billion lack access to adequate water for sanitation. Water-borne diseases are the leading cause of death worldwide. This situation is getting worse. Two thirds of the world population will be without safe drinking water and basic sanitation services by 2025.

The Sahara desert in Africa currently expands southwards at the rate of 5-10 km per year.

Australians are ranked 7th worst in the world for our average ecological footprint. The total human ecological footprint is estimated to have exceeded the biocapacity of the planet by 25%.

And I haven't even mentioned climate change, toxins in the air and water, soil loss or nuclear waste.

How does this make you feel?

UPDATE: When I first posted this, I avoided discussion of climate change because it is so politicised at the moment and seems to distract from the bigger picture. However, here is a useful site answering 26 common myths about climate change. H/T OSO.
