Card 5concept
Question

The four stages of a device's life

Answer

Mined, made, used, discarded — owners see only one of them.

Card 6concept
Question

Which stage dominates the footprint?

Answer

Making it. For a phone, manufacturing produces far more emissions than using it ever will.

Card 7concept

Recycling acts after the emissions have happened; a longer life means they happen less often.

Card 8concept

Card 9concept
Question

Sense, decide, adjust — continuously, without waiting for a budget cycle.

Card 10concept
Question

Who a sensor network misses

Answer

People walking, people without phones, and areas that were never instrumented.

Card 11concept
Question

Why automatic adjustment resists challenge

Answer

There is no meeting and no decision to point at, so residents have nothing to appeal against.

Card 12example
Question

Connection as a risk

Answer

What makes infrastructure efficient makes it reachable — a pipeline shutdown stopped fuel for a region with nobody touching a pipe.

Card 13concept
Question

What precision agriculture does

Answer

Measures variation within a field so seed, water and fertiliser go only where they are needed.

Card 14concept
Question

Why it is a strong environmental example

Answer

It reduces an input while holding the output, rather than moving a harm somewhere else.

Card 15concept
Question

What comes with the gain

Answer

Field data and repair rights both move to the machine's manufacturer.

Card 16concept
Question

The fix worth recommending

Answer

Rules giving the farmer the data and the right to repair — separating the environmental gain from the loss of control.
