I believe in a hands off approach.
Leave nature alone long enough and things work out. Conserve what you
have now feircely and try to protect it.

Humans always try to control nature and this often back fires.
Some restoratiion and creation work in conservation is worthy, some is
not. Adding mosquito fish is a bad idea IMO. Few fish bioloigist would
argue otherwise.
