Environment minister: Because of our concern about global warming, this country has committed itself to reducing its emissions of carbon dioxide substantially over the next ten years. Since trees absorb carbon dioxide, planting large numbers of trees will help us fulfill our commitment.

Summarize Argument
The environment minister concludes that planting lots of trees will help her country fulfill their environmental commitments. This is because trees absorb carbon dioxide, and the country has committed to release the carbon dioxide emissions.

Notable Assumptions
The environment minister assumes that planting a large number of trees wouldn’t itself contribute more carbon dioxide to the atmosphere than the trees would absorb, perhaps in the form of transportation emissions. She also assumes the country in question has tracts of land suitable for planting trees.

A
Owners of large tracts of private land are usually unwilling to plant trees unless they are given a financial incentive for doing so.
Perhaps the government can give them that financial incentive. Besides, there might be government-owned land suitable for the tree-planting project.
B
Over the last ten years the proportion of land that is deforested annually has not increased as much as has the proportion of carbon dioxide in the atmosphere.
The environment minister never said deforestation was the problem. She simply says planting trees is part of the solution.
C
When ground is disturbed in the course of planting trees, more carbon dioxide is released into the atmosphere by rotting organic matter in the soil than the new trees will absorb in ten years.
The environment minister overlooks the fact that there are other carbon dioxide-related effects of planting trees besides trees absorbing carbon dioxide. Merely planting trees releases a significant amount of carbon dioxide into the atmosphere.
D
Many climate researchers believe that global warming is such an urgent problem that carbon dioxide emissions should be substantially reduced in less than ten years.
The environment minister might agree. That doesn’t mean that a longer-term solution isn’t helpful, as well.
E
Gases other than carbon dioxide contribute to global warming, and trees do not absorb any of these other gases.
Perhaps the environment minister has other solutions for those gases. For carbon dioxide, the tree-planting project seems like a sound idea.
