The Volvo LCP was developed in the late 1970s. It used a 3 cyclinder direct injected diesel engine and achieved the unheard of figure of 60 mpg in town and 100 mpg at crusing speed.  The current fad of buying huge SUVs and trucks iscontributing to the problem -- too much CO2 being released into the atmosphere through the burning of fossil fuels. 


Carbon Dioxide
-- source of most of our worries about Global Warming. Mainly produced by car exhaust & factories.


Chloro- fluoro carbons
-- source of ozone depetion over Antarctica & the Arctic. Mainly produced by air conditioning & refrigeration leaks or venting.

The ozone layer above Antarctica and also now above the Arctic is greatly reduced because of the release of CFCs (chloro fluoro carbons) into the atmosphere.


-- another big source of atmospheric warming. Produced in rice patties, coal mines, and the digestion system of cattle
