I chose the subject because environment is a high priority subject today. This topic is up-to-date, since scientists, governments and people in general have become aware that we have to preserve the Earth to live in a healthy space. My plan is divided into three parts.

It burns slowly and only burns between 428 degrees Fahrenheit and 572 degrees Fahrenheit. At the beginning of combustion, the flames will speedily assail the surface of the wood. In return, the speed of propagation of combustion will be very quickly slowed down by the absence of oxygen in the material: it is the effect of coal-mining. [...]
