Thank you for getting it wrong and demonstrating my point. It is actually complicated - otherwise you would have gotten it right.

I can have the exact same lifestyle in France and the US and in US my carbon footprint will be twice larger. There is no reason eating out should have higher environmental footprint than cooking yourself. Buying locally grown vegetables is often the wrong choice.I can buy a tomato in the supermarket, and if it grown locally in the UK, it's carbon footprint will be twice larger than if it was imported from Spain due to fuel and heating needed for greenhouses. http://freakonomics.com/2011/11/14/the-inefficiency-of-local...

Let's dig into details, do you know how environmental impact of bananas compares to that of oranges? You might have heard avocados have high environmental impact, but is that per KG, or per unit of calories?

But let's consider buying a manufactured product, like a microwave. How would I, as a consumer, ever know if was manufactured with renewable energy or coal?

I am happy to be proven wrong. If you do claim it's easy, I take it you at least know what's your annual carbon footprint and how many trees you need to plant to offset it?

what about the other 3 examples I told you?

There are obvious things, there are complex things. But not caring is not a solution.

They are reasonable, and of-course we should care. Out of the things you listed, public transport is probably the most impactful.
