He may be next in line to the British throne, but he apparently worries just like any other dad or grandfather-to-be.

Prince Charles, a well-known advocate for environmental causes, told ITV's "This Morning" that he doesn't want his unborn grandchild to wonder why he didn't do more to tackle issues like climate change.

"I've gone on for years about the importance of thinking about the long-term in relation to the environmental damage, climate change and everything else," the prince, 64, said in the interview. "We don't, in a sensible world, want to hand on an increasingly dysfunctional world to our grandchildren, to leave them with the real problem. I don't want to be confronted by my future grandchild and (have) them say: 'Why didn't you do something?'"

Since Prince William and Kate Middleton, The Duke and Duchess of Cambridge, are expecting their first child early this summer, Prince Charles is especially outspoken about sharing his thoughts on the environment's future.

"So clearly now that we will have a grandchild, it makes it even more obvious to try and make sure we leave them something that isn't a total poisoned chalice," he added.

Also in the ITV interview, Charles shared his fears about the safety of his youngest son, Prince Harry, who is serving in Afghanistan.

"If you are a parent or relation to a loved one and that person is away in these incredibly dangerous and challenging circumstances, I know you worry all the time," said the Prince of Wales. "Certainly every night I worry. But he [Prince Harry] loves doing what he's doing and he's brilliant at it. I constantly meet the families of those who have lost their sons, husbands, brothers or sisters… and I have some understanding at least of what they go through."

Prince Charles spoke with ITV's Phillip Schofield and Holly Willoughby at the Clarence House, his official London residence, in support of the program's You Can Be Heroes Week, which highlights the success of the 2012 Olympic and Paralympic Games and aims to gain new volunteers across the UK.
