And again the issue of the filter is completely ignored.

How many tonnes of CO2 will be dumped into the atmosphere to run the expensive, ineffective and useless filters? This is how stupid your filtering plan is - no matter what you try to change the subject to, the new subject just continues to show weaknesses in your argument.

The only benefits of the filter are political... but you have a responsibility to the country to listen to the experts and do the right thing, instead of wasting money on political spin.
