What is the difference between man made wood and natural wood?

man made wood is made by wood it can be created and destroyed. natural wood cant be created or destroyed its natural. this is just a guess.

Answer:

Man made wood (also called composite wood) is engineered from wood chips, pulp, dust, fibers etc; the aforementioned material(s) is then mixed with resin and pressed into sheet goods and/or boards, some decking lumber have high percentages of plastic material mix, it's often referred to as plastic lumber.

Natural wood is what you find in a tree. Even if cut down and sawed into lumber, it still is natural wood, no additives have been mixed with the wood.
