Carbon dioxide is a green house gas and is produced by cattle and sheep and we as humans breed these animals for food. Every thing we do produces the co2 gas that traps heat in the atmosphere travel, cars, power stations, boats, everything. This everyone knows and is a fact, no disputes at all.
So here is my solution to reducing these gases.
Stop breeding humans,stop the baby bonuses, have one child policies,stop emigration.
But not what the Politicians want to here not what you want to hear either but there it is.
Having a green house gas tax wont fix anything just put more pressure on the poorer in society and they will remain poorer if this policy is not implemented. Don't breed. Your choice!
