       | Out of curiosity what is the water used for? Is it from

       | size of iPad Mini" referring to?

       | Hypothetically, turning off your webcam reduces overall network
       | traffic and would reduce the resources required to deliver
       | adequate connection speeds. But in reality, modest reductions in
       | internet traffic won't impact the datacenters and network
       | infrastructures that have already been built. A more likely
       | outcome is that network traffic is used for other applications.

       | Similar situations exist when pointing to the environmental
       | impact of meat production, for example. Not consuming meat would
       | reduce transportation of feed, and transportation accounts for
       | almost all of the carbon emissions from meat production. But that
       | only actually reduces emissions if we assume that the total
       | amount of transportation would go down, rather than the same
       | transportation capacity being used for other goods.

         | would be produced in the long run, thus it does have a positive
         | impact on the climate. We can talk about details or exceptions
         | but the general idea that less consumption = less consumption
         | [sic] = less climate warming is firm. I think the greater point
         | is that we have to look at a long time horizon with long
         | lasting changes to really see this, that's why we as humans
         | have trouble implementing these changes.

         | It's easy to measure. Camera and incoming video on is about 30
         | watts more power consumption on my Mac. I can see this on the
         | LCD on the UPS. It's not just about the datacentre.

         | mixing and reprocessing that may need to be done on the
         | streams. My own laptop isn't that old, and the fan spins up
         | often enough on calls that you know the CPU is chugging more
         | than usual.
