She wasn't being "paraded". There are many young women in our society that we might describe as being "paraded" but she is not one of them.
If we say that she is too young and does not have enough knowledge to be taken seriously on this issue, then surely - at least so far as knowledge is concerned - that might apply to many people who express views on climate change. How many people, on either side of the climate change debate, and whose views are given airtime, are qualified in and working as atmospheric scientists?
There are many people, including "experts", who deny that climate change is due to CO2 emissions. There appears to be many more who disagree but I don't know if that is because they are given more coverage. There is a view that there is another agenda behind the issue of climate change.
I don't feel qualified enough to come down strongly either way but I do feel that the environment is being dangerously degraded by human activity.
I think, if nothing else, this young girl has energised the campaign and has perhaps encouraged more young people to take an interest. She appears to be intelligent and is certainly very good at expressing herself in a foreign language. I think to make such disparaging remarks about her is really not very nice. It is older people who make all the decisions in the world and it seems that increased age does not necessarily equal increased wisdom. If it did, I don't think we'd be in the mess we're in now.
