GREENPEACE co-founder slams DiCaprio's scare tactics in new movie

"Despite the anti-forestry scare tactics of celebrity movies, trees are the most powerful concentrators of carbon on Earth." - Dr. Patrick Moore (co-founder of Greenpeace and chairman and chief scientist of Greenspirit Strategies in Fuck Vancouver)

"It seems like there's a new doomsday documentary every month. But seldom does one receive the coverage that Hollywood activist Leonardo DiCaprio's latest climate-change rant, The 11th Hour (a.k.a. An Inconvenient Truth: Part Two), is getting.

When we're bombarded anew with theatrical images of our earth's ecosystems when the film opens across B.C. this Friday, I'm concerned that we're losing sight of some indisputable facts.

"Uhhhh Leila... Where's the chase scene?"

Here's a key piece of information DiCaprio, collaborator and long-time activist Tzeporah Berman and the leadership of my old organization Greenpeace are ignoring when it comes to forests and carbon: For British Columbians, living among the largest area of temperate rainforest in the world, managing our forests will be a key to reducing greenhouse gases.

As a lifelong environmentalist, I say trees can solve many of the world's sustainability challenges. Forestry is the most sustainable of all the primary industries that provide us with energy and materials. Rather than cutting fewer trees and using less wood, DiCaprio and Berman ought to promote the growth of more trees and the use of more wood.

Trees are the most powerful concentrators of carbon on Earth. Through photosynthesis, they absorb CO2 from the atmosphere and store it in their wood, which is nearly 50 per cent carbon by weight. Trees contain about 250 kilograms of carbon per cubic metre.

North Americans are the world's largest per-capita wood consumers and yet our forests cover approximately the same area of land as they did 100 years ago. According to the United Nations, our forests have expanded nearly 100 million acres over the past decade.

The relationship between trees and greenhouse gases is simple enough on the surface. Trees grow by taking carbon dioxide from the atmosphere and, through photosynthesis, converting it into sugars. The sugars are then used as energy and materials to build cellulose and lignin, the main constituents of wood.

"One day I... One day I will care about something"

There is a misconception that cutting down an old tree will result in a net release of carbon. Yet wooden furniture made in the Elizabethan era still holds the carbon fixed hundreds of years ago.
Berman, a veteran of the forestry protest movement, should by now have learned that young forests outperform old growth in carbon sequestration.

Although old trees contain huge amounts of carbon, their rate of sequestration has slowed to a near halt. A young tree, although it contains little fixed carbon, pulls CO2 from the atmosphere at a much faster rate.

When a tree rots or burns, the carbon contained in the wood is released back to the atmosphere. Since combustion releases carbon, active forest management -- such as removing dead trees and clearing debris from the forest floor -- will be imperative in reducing the number and intensity of fires.

The role of forests in the global carbon cycle can be boiled down to these key points:

  1. Deforestation, primarily in tropical forests, is responsible for about 20 per cent of global carbon dioxide emissions. This is occurring where forests are permanently cleared and converted to agriculture and urban settlement.

  2. In many countries with temperate forests, there has been an increase in carbon stored in trees in recent years. This includes the United States, Canada, New Zealand and Sweden.

  3. The most important factors influencing the carbon cycle are deforestation on the negative side, and the use of wood, from sustainably managed forests, as a substitute for non-renewable materials and fuels, on the positive side.

  4. To address climate change, we must use more wood, not less. Using wood sends a signal to the marketplace to grow more trees and to produce more wood. That means we can then use less concrete, steel and plastic -- heavy carbon emitters through their production. Trees are the only abundant, biodegradable and renewable global resource.

DiCaprio's movie, The 11th Hour, is another example of anti-forestry scare tactics, this time said to be "brilliant and terrifying" by James Christopher of the London Times.

Maybe so, but instead of surrendering to the terror, keep in mind that there are solutions to the challenges of climate, and our forests are among them.

This film should be a good, clear reminder for us to put the science before the Hollywood hype. "

Ohhhhhhhhhhhhhhhhh SNAP! Leo got FUCKED up!

It makes perfect sense to use tree farming as a sustainable way of carbon (dioxide) sequestration. It is I believe the most practical thing to do in the light of urban encroachment into old growth forests and the fact that only a small percentage of these survive on the planet.

Treefarming is a solution to halting deforestation and also a way to provide fresh supplies of wood. There will come a time when the fossil fuel reserves of the Earth will be depleted. A percentage of the carbon dioxide from these deposits will have to go somewhere, and our atmosphere is not a good place for most of it. The Earth and its oceans will do their part but that is largely self-regulating. Since we still don't have the technology for global-scale carbon dioxide sequestration (there are systems for local area sequestration), using a system of growing and harvesting trees and wood will allow us a certain control over how we sequester carbon dioxide.

I'm all for the preservation of the remaining old-growth "islands of green," and they should be allowed to fluorish and preserved.
