A documentary or any feature film, like a good dessert, needs good texture. Some docs offer light delicate flavors, while others serve up crisp tawdry offerings but Crude, the latest feature documentary from director Joe Berlinger (Brother’s Keeper, Metallica: Some Kind of Monster) brings a feel so viscous its some wonder that the film and the emotions within it don’t just ooze into the theater.

And why wouldn’t the film be viscous with center of the film swirling around a legal case about the black gold being pumped out of the jungles of Ecuador. Some have called the case the “Amazon Chernobyl” but whatever the name, Berlinger delves head first into this the David versus Goliath story that circles around one of the longest and most controversial legal (not to mention environmental and human rights) cases ever.

Most of you know by now that deforestation, and the emissions that cleared forestlands add to the atmosphere, exacerbates climate change. But it may come as a surprise to learn that the opposite is true. New scientific findings suggest that climate change is threatening remaining forests more dramatically than previously suspected.

Until recently, climate scientists thought that trees, and the biodiversity they support, could withstand a temperature rise lower than 3C. New findings, announced at last month’s Copenhagen “Congress” to discuss climate issues, estimate that a 3C temperature rise will result in a 75% loss of forests. The report’s sponsoring organization, the UK Meteorological Office’s climate change research division, has said that a 4C temperature rise - consistent with current human activities - will cause 85% of trees to disappear.

Under even the most conservative climate change scenario - a 1C temperature jump - will kill off one third of Amazonian forests, which alone contain one tenth of total carbon stored in land ecosystems.

Scientists now estimate that the chance of staying below a 2C temperature rise are only 50%, even if drastic cuts in emissions take place over the next ten years. Already, a .75C temperature rise above pre-industrial has been locked-in, with another .6C expected, based solely upon current levels of greenhouse gases in the atmosphere.

Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on reforestation.

There is a vast unrealized potential in all countries to lessen the demands that are shrinking the earth’s forest cover. In industrial nations the greatest opportunity lies in reducing the quantity of wood used to make paper, and in developing countries it depends on reducing fuelwood use.

The rates of paper recycling in the top 10 paper-producing countries range widely, from China and Finland on the low end, recycling 33 and 38 percent of the paper they use, to South Korea and Germany on the high end, at 77 and 66 percent. The United States, the world’s largest paper consumer, is far behind South Korea, but it has raised the share of paper recycled from roughly one fourth in the early 1980s to 50 percent in 2005. If every country recycled as much of its paper as South Korea does, the amount of wood pulp used to produce paper worldwide would drop by one third.

The use of paper, perhaps more than any other single product, reflects the throwaway mentality that evolved during the last century. There is an enormous possibility for reducing paper use simply by replacing facial tissues, paper napkins, disposable diapers, and paper shopping bags with reusable cloth alternatives.

In early December 2004, Philippine President Gloria Macapagal Arroyo “ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people,” according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the heavy loss of life in landslides. And in August 1998, following several weeks of record flooding in the Yangtze River basin and a staggering $30 billion worth of damage, the Chinese government banned all tree cutting in the upper reaches of the basin. Each of these governments had belatedly learned a costly lesson, namely that services provided by forests, such as flood control, may be far more valuable to society than the lumber in those forests.

At the beginning of the twentieth century, the earth’s forested area was estimated at 5 billion hectares. Since then it has shrunk to just under 4 billion hectares, with the remaining forests rather evenly divided between tropical and subtropical forests in developing countries and temperate/boreal forests in industrial countries. Since 1990, the developing world has lost some 13 million hectares of forest a year. This loss of about 3 percent each decade is an area roughly the size of Greece. Meanwhile, the industrial world is actually gaining an estimated 5.6 million hectares of forestland each year, principally from abandoned cropland returning to forests on its own and from the spread of commercial forestry plantations. Thus, net forest loss worldwide exceeds 7 million hectares per year.

Unfortunately, even these official data from the U.N. Food and Agriculture Organization (FAO) do not reflect the gravity of the situation. For example, tropical forests that are clearcut or burned off rarely recover. They simply become wasteland or at best scrub forest, yet they still may be counted as “forest” in official forestry numbers. Plantations, too, count as forest area, yet they also are a far cry from the old-growth forest they sometimes replace.

Next Wednesday night, March 25th, tune into HBO2’s premiere of the documentary They Killed Sister Dorothy at 8 pm if you want to begin to understand the violence and injustice that surrounds the destruction of the Amazon rainforest. If you aren’t going to be home, then set your Tivo.

I was fortunate enough to see Daniel Junge’s film last month at the City of the Angels Film Festival in Los Angeles. The documentary follows the aftermath of the murder of 73 year-old Sister Dorothy Stang, known as the Angel of the Amazon, a Catholic nun and rainforest activist shot in the back while trying to empower local communities to set up sustainable farms while fighting illegal logging and land grabs.

The theme of China’s annual National People’s Congress taking place this week – the proceedings of which remain highly secretive beforehand – has been largely an economic one.

Although the environment is hardly the priority issue du jour, China has not entirely changed its course with regard to the environment, despite the economic turmoil, as a “worst case scenario” might have suggested. Legislation on the management of electronic waste, signed into effect this week by China’s cabinet, the State Council, is a key example of China’s continued commitment to making progress on environmental protection.

The new law mandates the establishment of centralized funding for enlargement and improvement of safe electronic recycling facilities in China. It also places responsibility on manufacturers, retailers, repair and customer service providers and recycling companies to collect and responsibly handle electronic waste; though the wording of the scope of their responsibility as well as punitive measures for noncompliance is vague.

These regulations aim to reduce a stream of pollution that builds each year. The problem of industrialized countries’ illegal exportation of e-waste on China and other developing countries has generated significant attention and debate in recent years, both inside and outside China. While advocacy groups like Greenpeace point fingers at the corporations for not taking efforts to control the disposal of their products or designing them with fewer toxic components, insufficient legislation and monitoring by both sending and receiving countries has exacerbated the problem.

A recent study shows that Alaska’s coast is melting faster than ever, and that along with the melting ice, more and more of the land is eroding into the ocean as well. The causes of the erosion also seem to be changing — in the past it was largely due to storms but that is no longer the case.

From 2002 to 2007, Alaska’s coast eroded at a rate that was more than twice that of the years 1955-1979. It is not just land that the sea is taking in these days either. It has swallowed a historic ghost town (Esook) and a historic whaling boat as well as an oil well (and probably more soon).

Paper appears to be high on the agenda of a number of organizations this week. It’s necessary. Paper is so ubiquitous – from tissues to toilet paper to memo pads to catalogs to the mess on your desk - that it is easy to forget, or perhaps more convenient to ignore, that paper manufacturing has significant environmental repercussions.

Paper production is the third largest contributor to climate change, the biggest source of deforestation and has a significant impact on water issues. It’s a dirty business, from the use of toxic chemicals and chlorine bleaches to clear cutting of forests like this one on the North Carolina Coast:

As land and water become scarce, competition for these vital resources intensifies within societies, particularly between the wealthy and those who are poor and dispossessed. The shrinkage of life-supporting resources per person that comes with population growth is threatening to drop the living standards of millions of people below the survival level, leading to potentially unmanageable social tensions.

Access to land is a prime source of social tension. Expanding world population has cut the grainland per person in half, from 0.23 hectares in 1950 to 0.10 hectares in 2007. One tenth of a hectare is half of a building lot in an affluent U.S. suburb. This ongoing shrinkage of grainland per person makes it difficult for the world’s farmers to feed the 70 million people added to world population each year. The shrinkage in cropland per person not only threatens livelihoods; in largely subsistence societies, it threatens survival itself. Tensions within communities begin to build as landholdings shrink below that needed for survival.

The Sahelian zone of Africa, with one of the world’s fastest-growing populations, is an area of spreading conflict. In troubled Sudan, 2 million people have died and over 4 million have been displaced in the long-standing conflict of more than 20 years between the Muslim north and the Christian south. The more recent conflict in the Darfur region in western Sudan that began in 2003 illustrates the mounting tensions between two Muslim groups–camel herders and subsistence farmers. Government troops are backing Arab militias, who are engaging in the wholesale slaughter of black Sudanese in an effort to drive them off their land, sending them into refugee camps in neighboring Chad. At least some 200,000 people have been killed in the conflict and another 250,000 have died of hunger and disease in the refugee camps.

Hey, you know that old conflict between religion and science? Remember the Scopes monkey trial in 1925 or the 1960 film about the case? How about the legislative battles of the last few years in Georgia, Pennsylvania, and Kansas over the mandatory inclusion of intelligent design alongside evolution in public schools?

Waiting for worldviews to change to accommodate new science is like watching the emergence of multicellularity. Keep in mind that Darwin’s On the Origin of Species is only 150 years old. Copernicus’s On the Revolutions of the Celestial Spheres was published in 1543. That book wasn’t completely dropped from the Vatican’s list of banned books for another 300 years. (I wonder if foundation-shattering books would fly under heresy radars if the titles didn’t start with “On the…”)

Chuck, on the other hand, just got fast-tracked! On Darwin’s 200th birthday, the Vatican is officially on board with evolution! Also, more than 800 pastors and rabbis are celebrating “Evolution Weekend” following Darwin’s 200th birthday February 12.
