The problem is trees are short-term (even the long-lived ones) and only a part of the solution because they are a part of the carbon cycle. We need to remove carbon from the carbon cycle.
Another part of the solution is pyrolysis of industrial plant waste into biochar/charcoal. This stable form of carbon can last thousands of years underground and does not need any fancy technology or equipment.
