firstly, all of the evidence suggests the most important thing is to protect what you ve already got. the most important thing is to protect existing forests. however, reforestation or restoration of forests can play an incredibly important role. i met the director of forestry in tanzania. i know the scale of what they need to do there. the key thing is is you plant the right tree in the right place for the right outcome. and, crucially, you plant trees that are going to be climate resilient over 50 or 100 years, as the climate might change. even if they re not native? even if you re not respecting what was the ecosystem before man s exploitative greed ruined it? so, i think this is on a case by case basis. in some cases, non native trees will be justified, if not essential, if the climate is going to change to such a point that native trees simply won t survive. in other cases, non native trees can be hugely damaging. there are many parts of the world where there s been mass plantatio
