Margaret, it's no wonder young people are anxious. They are bombard in the media to be afraid of the air they breathe, the water they drink, the food they eat and the fact that the polar ice caps are melting. Fear sells. I would remind the readers that it was medical scientists who told us, for about four decades, to fear the fat in our diets.....today, not so much. (The 'fat scare' is a cautionary tale for those in the climate change lobby who label anyone who questions orthodoxy. Interesting that in three U.K. newspapers today, The Independent, The Telegraph, and yes even the Guardian, there are reports on a recent scientific research report that says the climate models used to scare the planet likely overestimated warming. Of course now commentators are saying that CO2 mitigation is working inspite of the fact that CO2 ppm have risen about 10 percent in the last 20 yrs. But fear sells.)
