1. The world will fine without Bitcoin, mining doesn't harm environment.
2. Most people still using fiat for any transactions, Bitcoin is more used for investment rather than a currency.
3. No, how can someone create a forum when they doesn't know what the discussion of the forum itself?
4. Depends, Bitcoin doesn't solve financial economy nor giving away free money. But the early adopter who mine Bitcoin or collecting faucet do become a millionaire now.
5. Same, scammer will use other currency.
tl;dr Bitcoin do have less or almost none impact to the world.
