Gadge got it spot on - I was going to say more commies than russia, but same thing.
At present, it would be political suicide in Australia to ban petrol powered machines since we are so heavily reliant on them.
Overall, I have had this argument before with a woman; How do they make an Ozito cordless mower.
Shipping litihium from some third world dangerous mine which severely degrades farming land halfway across the world to China, then doing the same for the (limited) steel, and the oil for the plastics, all carried out in factories with poorly governed emissions.
Then shipped halfway across the world to bunnings. You use it for 3 years, with your lawn needing more water and fertiliser due to the way they hack at the blades of grass, you most likely use electricity from coal or gas fired power plants, then something minor breaks or the batteries lose efficiency; meaning you have to repeat the process.
Meanwhile, I use 0.6L of 25:1 fuel per mow in a victa 2 stroke (well in my case one of about 10 to choose from). Once a fortnight for 3 years means 45ish L of fuel and 1.8L of oil.
The mower had its raw materials extracted and refined once 30 years ago - and the only distance it has traveled in its life is from Milperra to Perth
Whose footprint is smaller?
Just because you p*ss of your polution to some third world **** hole doesn't make you better than everyone else
