Environmental Issues
If woodchips are harvested through sustainable forestry practices, then this is considered a source of renewable energy. On the other hand, it is clear that some harvesting practices, such as clearcutting large areas, are often highly damaging to forest ecosystems.
Theoretically, whole-tree chip harvesting does not have as high a solar energy efficiency, as compared to short rotation coppice; however, it can be an energy-efficient and low-cost method of harvesting. In some cases this practice may be controversial when whole-tree harvesting may often associated with clear cutting, and perhaps other questionable forestry practices.

Famous quotes containing the word issues:
“The current flows fast and furious. It issues in a spate of words from the loudspeakers and the politicians. Every day they tell us that we are a free people fighting to defend freedom. That is the current that has whirled the young airman up into the sky and keeps him circulating there among the clouds. Down here, with a roof to cover us and a gasmask handy, it is our business to puncture gasbags and discover the seeds of truth.”
—Virginia Woolf (1882–1941)
