Your fireplace and wood stove are major drivers of deforestation
If you burn wood to heat your home, you may not realize how many trees are consumed every year by this choice. It's often difficult to see this since most of us have wood delivered in trucks loaded with smaller and sometimes split pieces. On Gabriola Island, our consumption of wood is the equivalent of 545 logging trucks/year of trees, and this consumes 55 Ha (136 acres) of mature forest every year. Much of this wood is imported from woodlots on Vancouver Island. If parked end-to-end, these 545 trucks (21.5m in length) would be 11.75 km long - almost the length of the island. Here's the math and the hyperlinked references to support these calculations. Forests in B.C. are relatively productive compared to other parts of the world. A Ha of mature forest yields on average 400 cubic meters of wood. Not all of this wood can be used as firewood but we'll use this number since data on actual amounts of usable wood are difficult to come by. A lower number of usable quantities...
