Many things are wrong...

Explanation:

Old trees provide a better environment for new trees. If you cut down old trees, you loose suitable conditions there.

One old tree is capable of providing huge amount of oxygen. One young tree (2 years old) is not. Nobody can guarantee all young trees will reach maturity in the future even under the best management practice. But old trees allow new trees to grow.

Clearcutting practice is especially dangerous. If this practice is selected, soil organic matter, that is necessary for new trees, as well as nitrogen and phosphorus, and other factors will most probably go away due to erosion.

There are many issues but to be concise I provided only some important facts here.
