Wood is a renewable energy resource and contrary to general belief wood burning does not contribute to the catastrophic climate changes we are starting to witness around the planet. Fossil fuels like oil, gas and coal which are extracted from deep beneath the earth surface are the main source of greenhouse gases that destroys the environment. Trees recycle CO2 from the air to grow, using the carbon to build its structure to about half the weight of wood. When the tree dies, it rots on the forest floor and slowly releases the carbon back in the air completing the natural carbon cycle. When wood is burned, it quickly releases similar amount of carbon in the form of CO2 thus completing the same carbon cycle.
