You must be able to understand the earth and how it works in order to be able to care for it correctly. This is our planet, our home, our sanctuary and if it dies, so do we. Hopefully some students will take an interest in it and further their studies and help save our home.
Because it's necessary for humans to know about the environment they're breathing in. We need to know where we are living & what are the circumstances & conditions. What it made of, where is it & how it works, what is around us & how the "Life" created together on this planet & if it going to continue or not or what are the dangers & possibilities.
It's so much better that we know & die rather not knowing & die.
