Re: Plastics Pollution in Our Oceans . . .

I just completed an article on environmental impact of a sailing trip as many of us do it regularly. I hope to contribute to this discussion and it is not only the plastics in the ocean that is the problem.

See my article on https://www.erol.at/logbook/index.ph...t_type=message

Feedback more than welcome!

Re: Plastics Pollution in Our Oceans . . .

Interesting article and thank you for producing it. However, how do you get 2.68kgs of CO2 out of 1 litre of petrol which must weigh less than 1kg?

It is the oxide (O2) that an engine needs to burn a liter of diesel (C). It takes O2 out of the air. And it needs a quite many of cubic meters of air to burn one liter of diesel which leads to the average relation 1 L Diesel => 2.68 kg CO2.

Re: Plastics Pollution in Our Oceans . . .

To make CO2 you mix one unit of cabin with 2 units of Oxygen.

Carbons molecular weight is 12 so a unit weighs 12 somethings.
Oxygens molecular weight is 16 so 2 units weigh 32 somethings. M

If we are talking pounds 12 pounds of carbon, from fuel, mixes with 32 pounds of oxygen from air to make 44 pounds of CO2.

That’s how it works.

(hope i did hat right, too many years since HS chemistry).
