There are suttas when the Buddha speaks about his past lives, the Buddha has always been a master of his field. In one past life he was the master of wheels, by investing and sacrificing his entire life to a speciality he becomes a master and is able to discern the tiniest of differences and details, and in that specific life, regarding wheels. He could desire to make a wheel roll on for a very long time or a short time (aka Quality) depending on his willingness to exert effort on the wheels (aka meditation subject).
Therefore, the more we let the 3 poisons distract us (improper attention) from our meditation subject (nibbana) the more we dillute and waste our short lifespan’s potential.
Unless you’ve attained the final goal, it’s best to not let your attention stray into other subjects of attention. Your short human lifespan will not allow you to be a master of multiple things, so pick one subject and sacrifice your life to it.
Better to be a master of one rather a novice of many. Mastery only means one thing: quality. Quality over quantity.
As for climate change, if I wanted to determine myself to that subject, I would be debating professionals on a scientific forum, not on a Buddhist forum, but I have recognized that the dhamma is a vastly superior subject. So to discuss climate change on here would be like to ask for a Big Mac burger at the world’s highest quality restaurant, and totally miss my window of opportunity to taste something rare, divine and supermundane, instead for something common, low quality and cheap.
