Humans will choose the best solution for themselves, so all you have to do is give them a solution that does not involve destroying the rain forests. Land ownership is the key. Most people don't destroy what they own. I don't dump trash in my yard because it's mine, not because the government says I can't.

BTW, deforestation in the Amazon has dropped dramatically in the last decade.

It's not true. That's what I understand. CO2 is like water. Once the plant gets enough it grows. Doubling the water or the CO2 doesn't affect growth.

Planting more rain forests definitely helps sequester CO2. More CO2 does not stimulate more growth however,

Funny you should mention knowing something about climate change...

This is from scienceline

" During their lifetimes, plants generally give off about half of the carbon dioxide CO2, that they absorb, although this varies a great deal between different kinds of plants. Once they die, almost all of the carbon that they stored up in their bodies is released again into the atmosphere."

The rain forests are filled with all kinds of decaying matter that gives off CO2 and I believe that respiration occurs at night which gives off CO2 (someone who studied botany can correct me if I'm wrong here but I seem to recall being taught that plants use Oxygen at night and give off CO2). The question is when all things are considered do they absorb more or give off more. I've always been of the opinion they absorb more while living and that higher levels of CO2 results in faster plant growth but I've never studied botany.


It all depends on the availability of oxygen.

Plants materials that are not in contact with oxygen after they die will not release carbon.

Where there is now coal, there was once a peat bog.

That might be the most ridiculous post I have ever read. It's so silly I refuse to post links. I can assure you that the amount of water and CO2 has a huge impact on growth. Ever hear of growth rings on trees?

I planted a royal palm 11 years ago and did an experiment and watered it every day for 4 years with septic water, the growth was exponential!!!!! its 60 feet tall now.. I've asked visitors how old they think the royal palm is?? and they always think it's like 50 to 60 years old.. the same day I planted five other royal palms and did not water them at all, they were left to grow only by what nature would provide, and they are one fifth the size.. water and nutrients makes a huge difference...

The world`s rainforests have been around for a long time because the nutrients needed to sustain a them have been present in sufficient quantities.

If the nutrients are there, nature does the rest.

The solution for most in Brazil is to burn rainforests to make way for farms and cattle grazing, what solution do you propose to change their ways. Landownership is actually what is driving the deforestation, same as was the case in the early part of our development. Yes deforestation has decreased the last few years but still very significant and it accounts for around 70% of their carbon emissions.

The soil for rain forests in the Amazon are very infertile, once the high canopy trees are removed it's more like a desert. Very difficult to restore and promotes erosion and contamination of waterways.
