Should we use GMO trees to slow climate change?

I believe that it is more complicated than they think, because giving such advantage to an species would alter ecosystem and population dynamics. Say you introduce that mutation to a hundred willow trees and you plant them near a natural reserve, then when they flower, through cross-pollination potentially thousands of willow trees will end up having a mutation that makes them grow faster and that sounds good until you consider the fact that trees requiere sunlight to grow and faster growing trees would shade the slower ones, which could slow their growth and thus reaching maturity would take longer, which would in the long run decrease their populations. That's the best case scenario because slow growing trees could simply get so much shade they can't even photosynthesize enough and die. I think this could be a good idea for crops since we need them to be more efficient but doing it to other species that will inevitably end in the wild needs to be reconsidered
