I came to know about this on David Attenborough: A Life on Our Planet: While it is good to know that we have more trees than we did 35 years ago, the biodiversity of coverage has been seriously damaged. This basically means we do not have that massive variety of trees anymore. A lot of trees we grow today are mostly coming out of secondary commercial purposes. I remember a huge forest in Cambodia was cut down and repopulated with nothing but an oil plantation which isn't necessarily a great thing. The ecological imbalance caused was great enough that animal numbers decimated quickly and never returned to the original level. It might have helped offset some CO2 levels, but again, it had other adverse effects such as requiring huge amounts of water to keep it going.
