This fire won't have more impact than people who are eating meat and where we need to deforest the entire planet just for making their meat. Without talking about greenhouse gas.
Your English and style sure is a good match for Semobo. So is the style and use of logic. Same person (or algorithm)?
Anyway, if omnivorous humans required the 'entire planet' to be grazing lands in order to satisfy their needs for meat, then why is the 'entire planet' not currently deforested?
