I do understand both of these, and I advocate using managed forest areas with newer growth - perhaps you misunderstood? We simply don't have as many old growth forests that our ancestors have had due to deforestation. The trees being planted in suburbia aren't offsetting what we are using to build the houses either, and definitely aren't replacing them where they were harvested (the forest, in general). We also aren't planting the same varieties of trees that we use to build the houses, as trees in housing development are generally chosen for looks, speed of growth, and size.
