So my youngest DC is 12. Incredibly aware of environmental issues and is beginning to think of a career in Marine Biology. Already follows environmental blogs, has joined school focus groups for this and keeps our family in check on our environmental responsibility. And is very sad to have read Prince Harry's comments on third children being something that is damaging to the planet. I do find it rather frustrating that I have had to discuss this with a child. The planet is being damaged and no one can deny it. But it is really naive to point the finger of blame on third and subsequent children in a family. It doesn't matter to me how many children you have as long as you bring them up to add something to society rather than take away ( and this includes the environment). The more children the better , as long as they are contributing and making the world a better place? I think he should apologize to all third children ( and 4th and 5th). And that includes his Mother, Prince Louis, my lovely 12 year old and many more fantastic human beings who really don't deserve to be told that they are bad for the planet!
