<p>As mentioned before, your son can study his science interest in a BA and need not do engineering. That can be combined more easily with MT. My daughter (not my MT kid) is very interested in sustainability and that is a thrust of her grad school application and she is going into architecture. You can study “green environment” and related issues in fields besides engineering. He may want to examine Environmental Science major programs and what they offer and combine that with MT. He could do a BA in both. Or he could do a BFA in MT and a minor in Environmental Studies and decide to go further with one or the other in grad school.</p>
