Grammar, Usage / Use of first person in essay regarding humans [3]

I am writing a huge research paper on Climate change/ global warming. My main paper concentrates on the fact that Humans are responsible for this issue. Throughout my essay I use the pronoun "WE" to refer to us as humans. I think that it fits well with the paper and it shows a sense of faultiness/ blame. ex: We are the ones contributing to this problem.

I use it a lot and I do not know if this is okay considering its a rule of thumb not to write a paper in 1st POV. -thanks
