I don’t use a mouse, mate.

If that’s the case, then would you not say that all artworks are unnecessary and therefore contributing to climate disaster?

Or musical instruments, being made of different metals and materials, shipped around the world, also superfluous and we should not have instruments?

You see, if you put it that way, then virtually everything in the world is a waste.

So instead of telling people what to buy or what to do, we should just aim not to buy unnecessary things that we don’t use. If someone finds the mouse useful and wants it, go ahead. He/She can cut back on something else.

It’s not a zero-sum game. Someone using this mouse could be one who cycles, doesn’t use an aircon and have solar panels. Conversely, someone who doesn’t use this mouse could be someone with 3 cars, blasts aircons all day and wastes resources mining cryptocurrency. But it’s much easier to pounce on what we can see, eh?

The mouse (or any other object) is not the issue. It’s the attitude of unnecessary consumerism.
