Gold is used in jewelry and has been used for a long long time. Gold is another good conductor which lets electricity go through the gold.

This natural metal is good for exterior wall and roof cladding. Other uses include cans, foils, kitchen utensils, window frames, and airplane parts.

Timber is found in many different rain-forests and are logged illegally. Timber is used for fuel in fires, in some buildings, and illegally logged for furniture sometimes. Not only is logging illegal but it harms many animals and their habitat. This damages the environment and the rain-forest because the logs are dragged through the forest which damages the other plants and trees around it.
