>> reporter: good morning, matt. prince charles has made his life work campaigning for the environment. he says becoming a grandparent just makes that more important. he also says he worries every night because his sons don't just honor the military, they serve in it. in a rare interview, prince charles says he feels he will have to answer to his royal grandchild on the state of the environment .
>> you are soon to be a grandfather for the first time, so many congratulations.
