Richard Hebda on ecosystems and GHGs and green energy
Posted by bc-creeks under General , Third party articlesDr. Richard Hebda, Schools of Earth and Ocean Sciences and Environmental Studies at the University of Victoria and a respected, published author and presenter on climate change speaks about carbon sequestration in BC forests, and the risk of land developments which may disrupt this and release significant amounts of greenhouse gases. Forests, in particular, old-growth forests in complex ecosystems sequester large amounts of carbon compared to replanted seedlings in a clearcut. Carbon stewardship and full cost accounting, and eco-footprint analysis should be a pre-requisite to province-wide developments of power projects. Do we release more CO2 through the construction process, or modification of the landscape? Do we reduce the environment’s adaptive capacity by changing the way rivers run? Do we influence fish stocks and the way fish use rivers? Disturbing the landscape weakens its capacity to make adaptations.
