How do we know what we know?

For me, this question leads to another question. Are we born with certain knowledge that is to guide people to definite truths? What you know essentially leads people their personal beliefs. Something I know is that it is vital for humans to coexist peacefully with nature and show it respect. After all, we are just a part of the whole system. A system that was working much longer than we humans has been part of it.  I believe coexisting with nature to be a self-evident truth. The way we treat the earth highlight the misconception that it is for supporting the human race. In a sense this is true, but only partially, we as humans also have the responsibility to care for the very earth that supports us. I’ve learned to respect nature through spending extended time in the heart of it. If this is a truthful piece of knowledge, then it shows that through industrialism and technology humans of grown apart from nature. This makes me think that maybe the some of the beliefs that we hold are inside of our true nature and have simply been dissuaded by opinion. Are some opinions completely false, while other opinions are really fact and upholding vital truths in order to be part of the balance on earth? So going back to the original topic, we know what we know through experience. I wholeheartedly stick to the knowledge that we need to make peace with earth, because all that we experience and KNOW, happens on this planet. Well, as far as we know… ah philosophy.
