A scientist believes that asthma is triggered from central heating and double glazing and other scientist says is
from air poution ... how can they test this???HOW CAN THEY TEST THIS THEORY??

They need to run experiment. That's how you test any hypothesis. You run an experiment. They need to have control subjects and they need to set up environments, one with central air and double glazing and one with standard levels of air pollution. They need to have several test subjects so they can see a lot of results to make a conclusion. They need to make sure the environments remain constant so that they can be sure the results are constant. They would need to watch their subjects to see which environment (if any) triggered more responses in the subjects.

I would think that th scientist saying central heating would need to be more specific as to type of heating. Radiators and baseboard water heating can be central and not blow around particles like forced hot air heaters. There is indoor and outdoor pollution. Does the heating system take in outside air? You need to set exact parameters and then do an experiment.

They should survey a pool of asthma sufferers as to their addresses and as to whether or not they have central heating and double-paned windows. Then also collect historical data on levels of air pollution at the sufferer's addresses. With this set of info, some conclusions should be deducable.

It depends on what u call pollution. If CO2 is it u are wrong because the plants have already recycled most of it.
