Unfortunately millions of hectares of rainforest is also mostly irrelevant compared to the amount of CO2 going into the atmosphere from burning fossil fuels.
You have to take into account not just the annual sequestration of carbon dioxide by rainforests, but also the carbon already stored within them that is released when they decay or burn. A lot of the land being deforested is used to make way for livestock which adds insult to injury. Moreover, the deforested land accelerates the greenhouse effect by absorbing more energy from the sun.
Why is the land being converted to meat production? Surely the problem is one of economics, development and poverty more than anything else? Give the people that live there better options and the deforestation will take care of itself.
The filthy rich (and constantly growing richer at the expense of everyone else) who are doing it have zero interest in giving the people that live there anything more than they absolutely are forced to give in order to be allowed to rape the planet for more profit. Giving the people that live there better options is the last thing they want to do, as then those people would have no incentive to give up their land and rights to make those rich people richer.
