It wasn't intended as my telling you how to do things - simply a reminder (for all who are reading this) that using internet and data instead of aerial broadcasts (where possible) typically account for a whole load more carbon emissions.
This isn't widely known, there are many here who are extremely keen to do their bit for global warming, hence the mention.
You're correct to mention that one person won't have a large effect on our planet, just as the UK with 1% of global greenhouse gas emissions won't - but at the very least people should be aware of the facts. The more people who take a lead, the better.
