What are you saying? Perhaps first you may take Marsden book and give it a complete read.
Here is another source to back up that statement
According to data from Global Forest Watch, an online mapping platform that tracks tree cover loss and gain in near-real time, industrial development and forest fires in Canada’s tar sands region has cleared or degraded 775,500 hectares (almost two million acres) of boreal forest since the year 2000 (Map A). That’s an area more than six times the size of New York City. If the tar sands extraction boom continues, as many predict, we can expect forest loss to increase

As far as the wood pellet industry, apparently just makes matters even worse.
Natural gas being praised by Greens, not if they read the complete life cycle
Furthermore, all those power plants that burn natural gas will still spew CO2, albeit less than the equivalent coal-fired power plant. In a world aimed at zero emissions, that reduction is not good enough ultimately. In fact, the more than 1,000 gigawatts of natural gas–fired power plants built around the world would spew roughly 300 billion metric tons of CO2 if operated over the next 50 years—or more than half of the world's remaining carbon budget. Exceeding that budget may lock in the worst of climate change, whether fast sea level rise or extreme weather. Cheap natural gas may even slow the shift away from heavy industry in the U.S.: New fertilizer plants and chemical plants have already been built as a result of cheap and abundant natural gas and new steel plants may not be far behind. Finally, natural gas can leak, adding methane to the atmosphere, which also exacerbates global warming.
