A large truck would produce as much as pollution as 150 cars!
No. Construction equipment used to build the station will burn fossil fuels and produce some pollution. When the station is complete it will produce pollution free electricity. The station will require some electric power from the grid to operate, and some of that electricity may be produced by coal powered plants which do produce pollution, but the geothermal power station will not produce pollution.
No, I think cars produce more pollution because of the gas being used.
They do not. They produce natural waste, which is far different then real pollution.
most do
Yes.

sorry- no such thing as an "average factory". It depends on what they make, and the controls they have in placed. Some factories produce NO pollution.
they do not produce pollution
no
No
They by themselves produce little or no pollution. The pollution comes from the manufacture of the blackboard and book. There may be chemicals in the blackboard and book that can leech out, but it is probably extremely small. I work in a paper mill and we monitor the pollution we produce from the paper making process very closely and we try very hard to minimize that pollution.
