Why do they still use carbon dioxide in the soft drinks industry?
The quantitiy is quite small due to other sources of CO2 in the atmosphere almost completely insignificant. Much of the CO2 is produced in manufacturing where it is a biproduct of combining calcium carbonate (a rock) with waste acid. The environmental danger of releasing the various acids from industrial production without neutralizing them would be far greater than the CO2 itself. Dont waste your time on the last 0.001 % of the problem the cause of global warming is elsewhere. The production and transport of the drinks (even water) releases more CO2 from burning fuel than the CO2 in the drink themselves. This is from the cost to make the can/bottle and cost to ship it to the consumer. The aluminum industry spends nearly $2 billion dollars a year on energy in the USA. Even if nearly all cans were recycled, the energy (and CO2 released to make the enrgy) would still make the CO2 in the beverage appear tiny.
