This is rarely the case. I repeat: THIS IS RARELY THE CASE! Like I said, the work I've seen done at undergrad, grad, and doctoral levels is all the same: atrocious. You would consider the published reports fiction if you were actually there seeing their projects happen. Please don't trust someone just because they have a degree.
No offense, but I would hardly base the integrity of all researchers/scientists on what you've seen by some people at a university.
Not just at my university, but across the world. Professors, conservation efforts, fish and wildlife service, zoos, people actually in charge of a conservation plan for a species, etc. Like I said, don't just trust someone because they are a scientist/researcher without knowing what exactly it is they're doing.
Also, when they get employed eventually all the knowledge just clicks in their head right? Its a pattern of poor learning and instruction, jealousy, ego, faking and exaggerating data, etc. just like everything else in life where people play stupid games. Not all researchers negatively impacts plant and animals species, but I've seen a fair number that do.
