Why don’t amazon and other international Internet shops start working on an option where you can ask for delivery by surface mail instead of air mail?

That would be – for us – an easy way of getting down the CO2 emissions a little from this transport of goods. There would actually be no substantial problems for the customer, unless you are really in a hurry.

I am usually not, getting the things a few weeks earlier or later would usually make no difference.

I haven’t checked how big part of the world’s CO2 emissions this is, but the business has certainly grown the last 30 years.
