What massive environmental impact? Commercial art sounds like one of the least energy intensive occupations. You just sit in front of a laptop with low energy consumption. You are sharing a building with hundreds of other people. You probably take public transport instead of commuting by car, live in a small apartment and share heating with other people. Really the biggest pollution source is the food that you are eating as an artist and that's not your fault. It's the fault of the farmer that is using diesel tractors, fertilizing his plants with artificial fertilizer, shipping his food with diesel trucks. All of these pollution sources will have to switch to renewable energy one day. What about that laptop? It's probably running on Renewables today!
