Students who are interested in learning about the environment should not be dissuaded from doing so but only if they have proved their proficiency in other basic courses such as U.S. history. Until then we need to focus on producing well-educated citizens steeped in their country's history and mindful of their civic responsibilities.
I've learned that life is very tricky business: Each person needs to find what they want to do in life and not be dissuaded when people question them.
