All they do is mix up a few ingredients....like making cake batter....I still don't understand how concrete can be bad....maybe if you didn't wash it off your hands while you were pouring it......but really.....
To be fair, it's the concrete powder that takes enormous amounts of energy to produce. I'm no expert but I believe it's a certain type of sand which has to be heated and dried at very high temperatures.
Mixing it with water only takes a fraction of that energy. :)
Environmentalists are carefully touching the topic, knowing that if people know that concrete isn't very environmentally friendly, they might choose to live in wooden single family homes instead of commie blocks. Some of them even goes so far that they wanna build commie blocks and even parking garages in wood instead of concrete. Now that's insane.
