like I said, I'm a complete noob here... here is a CPU hashing away super slowly "polluting" (do you mean in the used up electricity, or is this a bitcoin thing?) Incidentally the electricity from my utility company is almost 80% hydro (if that is the concern)?

CPU mining is extremely inefficient and ineffective. A high-end CPU can mine at about 50 MH/s using 150 W of power. A typical modern ASIC miner can mine at about 250 GH/s using 150 W of power, which is 5,000 times more efficient. Even using hydro, you're polluting 20% of 5,000x = 1000x as much as someone mining with an ASIC powered by 100% fossil fuels for the same hashrate. Also, for the cost of a single CPU, you can buy a miner capable of 1,152 GH/s, which is 20,000 times more powerful than the CPU.
