This Earth does not have magic that can be directed by people to their own desires. It follows low-level laws of physics with exceptions detailed below.
Rather, some other parallel reality has magic with wizards and useful control over said magic. Our reality is on the receiving end of it only.
In that reality, if someone uses magic to produce a waffle for breakfast, where does it come from? From our reality! Now that's not the most typical example, since locating an object with matching properties—if the same thing even exists here at all—somewhere on the planet requires a great deal of mana to animate a low-level intelligence on this end to find one.
Places line up between the two realities, with the broadest geographical features of the planet being the same as well. If you (in the magic Earth) want to get rid of some trash, you can vanish it magically and it shows up in the same spot in this un-magical Earth, un-invited and unannounced.
Sometimes people are vanished, so we've had a few immigrants to learn the situation from and piece together the full story.
Certain magical locations there correspond to natural resources or unique conditons here, so getting energy to power more advanced magic or getting hot or cold across happens at locations where conditions are different. Yellowstone caldara here is a mundane plane there, and once discovered used as a source of energy for magical forges and a huge industrial center sprung up there.
The American Great Lakes don't exist there (I guess glaciation was different) and suddenly become a source of irrigation there.
In this reality, we can't control any of it. Science and engineering work, except that matter, energy, and entropy somehow appear and disappear at the command of someone on the other, magical, Earth.
What would happen if this started happening now?
What would the technological and industrial development have been if this started happening some time in pre-history, and increased in scope over time just as our exploitation over natural resources have in reality?
How might we interfere with or benefit from it, anyway?
