Is wood a renewable or nonrenewable resources?

Answer 1

Renewable is the key word here. Resources like gold, silver, oil, coal are not renewable, at least on a time scale we could recognize. When you use up a non-renewable resource, it's gone.

So some forests are renewable, that is, trees can be replanted and grown to maturity in place of those that are cut down.

Others are not renewable, like rain forests that have taken thousands of years to grow.

If you cut one tree down, you can plant one in its place. In forestry, this is called rotation. Many forest lands in, for example, the south of the USA, are on a 35 year rotation. The timber will be selectively harvested up to 35 years of age, then cut and replanted. This timber is a renewable resource, also called plantation forests, which are planted and then cut down to make paper. It is sometimes called a sustainable resource, so long as we keep planting and growing trees at the same rate or better as we cut them down.
