Could be, but those fast growing species are sometimes non-native (to the country), not integrated into the native ecological system over centuries of adaptation and symbiosis, huge water suckers, stifle native plant and tree growth, etc. And often the native forests with much greater biodiversity (and multiple plants valuable and tradionally known and used for food, fibre, fuel, firewood, shelter, herbs and medicines, etc., have been chopped down to plant those monoculture tree farms for, say, paper alone. Seen and know of actual cases of this in some parts of India I am familiar with. Even the state goverments now know of this and there are now some efforts to reverse the trend. An example: eucalyptus and wattle in the mountains of South India, particularly the Western Ghats.
