Why should people in the northern hemisphere be concerned about rain forests in the southern hemisphere

Because air quality circulates through the entire world. Getting ride of rainforest in the Southern Hemisphere will hurt the air quality which will eventually get to the rest of the world.

But isn’t this a question asking ur opinion this is something about u. ( well i would pick somewhat true bc that’s what i do when i don’t know what to choose ) hopefully this =“)

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
