Parental child avoidance is now more visible as phones are consumed in public, is it worse now than historically where parents would get home from work stick the TV on and say not a word until 'bed time' was called out, who knows?
To simply say 'NO' to smartphones is too simplistic, as they have considerable benefits as well as detriments. As a parent to a teenager I've had to think carefully about phones, social media, access to harmful information, etc. The social interaction they enable is fantastic, my son maintains friendships with people who have left the area and moved across the world, I find him frequently laughing with his friends about the latest meme, he brings interesting topics up at the dinner table about things he has seen he has a broader education because of the device. He also talks utter garbage at times quoting misinformation that he has seen, but this gives the opportunity to learn how to think critically etc. As a parent it is harder work but I think overall the pros outweigh the cons, and to not learn how to use the technology will hamstring an individual in the future. A quote I like is "all progress takes place outside the comfort zone".
Your view is that the economy is more important than the environment. The green group militant's view is vice versa. Much of your language is equally militant, stating this and that will happen without any presentation of any data or evidence. As others have said they think being a leader in this area will provide opportunities for growth, and being a leader will enable us to develop solutions that are exportable and valuable. Can you admit that there is also opportunity in being a leader?
You raised some interesting points regards top global polluters, this caused me to go and look at the data, from which I learnt something new. I learnt that since 1990 the UK has roughly halved it's CO2 emissions, no other country in the world has achieved such a cut, something to be proud of! I learnt that China's per capita emissions are higher than the UK, however all the stuff they make for the UK is included in their numbers so this muddies the water. This research has changed my view and makes me think more pressure is required on some of the developing nations, but perhaps is support and regulation that encourages low carbon production of goods exported.
Spending energy debating a topic is only worthwhile with an open mind and a willingness to understand the other's position, if you have a closed mind and a hammer then likely the other party also does and it becomes a fight not a debate.
