There are large old growth forests in the Canadian boreal regions that are currently being destroyed by logging companies like Resolute. Since Canada has a strong government, Resolute can do things like file malicious lawsuits against non-profit organizations that are exposing this destruction:

Brazil, in contrast, has a very libertarian government, so companies simply hire private hitmen to assassinate non-profit environmental group activists:

Almost all of the old growth forest in the United States was destroyed by capitalism prior to World War I. For an extremely depressing photographic account I recommend the book Kinsey, Photographer: A Half Century of Negatives by Darius and Tabitha May Kinsey. It is a photo book of hundreds of photographs of the Pacific Northwest's giant tree forests being destroyed. The scale of these trees is almost impossible to comprehend today (only a few scattered patches of Giant Sequoias remain in California), and most of them were cut down to be made into small siding and roof shingles.

There are a handful of old forest groves left on private lands, and there are a few land trust organizations trying to save them. For example, I donate to the Save the Redwoods League, and their big project now is acquiring Mailliard Ranch.

I'm not sure why you're downvoted because you're correct. But I suppose microcolonel's point is that capitalism has converted them to private forests for harvest.

I should note that growing forests consume 10-11 times more CO2 than old growth forests, and the US is excellent at keeping growth rates as high as possible or a given tract of land.

when a forest grows, it consumes c02, when it dies, it returns it. its zero net.

Not necessarily, if one make bio-char from the wood the carbon is stable for ~10k years, even if buried in the soil (terra pretax). This can be done successfully during the gasification process for producing heat, syngas and electricity. Also any items made from the wood that do not rot will not release their CO2 for the lifetime of the product.
