Here's a summary of the Hacker News thread about the number of trees in the North American boreal forest: A Hacker News post linked to a Wiley.com article discussing the number of trees in the North American boreal forest. The post garnered a few comments, sparking interesting discussions. One commenter cautioned that a high number of trees doesn't necessarily equate to high ecological biodiversity, citing tree farms as an example of a biome with low diversity. Another commenter pointed to a BBC article about a satellite project aiming to directly count and "weigh" the world's estimated 1.5 trillion trees. A third commenter discussed the albedo effect, referencing a Nature article that suggests that darker trees in the boreal region might absorb more sunlight and contribute to global warming, potentially offsetting the CO2 benefits of increased tree planting.
