for the production of stuff (mainly new things we buy) in factories and in the production of electricity

for transportation (anything with a combustion engine like cars, buses, airplanes, boats),

which is produced for food, such as cows and by garbage decomposing in landfills.

Water vapor increases as the temperature of certain parts of the globe increase (due to air pollution) and as we waste water, like that which is stores underground in our aquifers (this is our drinking water for the most part).

Water vapor is caused by evaporation[ɪvæpəˈreɪʃn]
(испарение) of water and is increased by using water besides rain to water our lawns or plants, wash our cars, water farm fields and golf courses, the diversion of rivers into canals, etc.. It is also created when factories manufacture stuff for us to buy.
