My light-bulb moments, thanks to grumpy Greta

GRETA Thunberg has had an effect on my eco activities. Every time I hear her hectoring and blaming my generation, which gave her MRI scanners, mobile phones and a comfortable life, I turn another light on (“Thrifty shift to eco living”, January 13).

I will not be lectured to by a child who should be in education.

Go to China and India and convert them to your cause. Oh no, they won’t indulge you, will they?
