== What is an "environmentally responsible fish"? == 

 "Environmental Defense have suggested that Atlantic herring (Clupea harengus) are one of the more environmentally responsible fish." 

 Now, at the very least, that should be "Environmental Defense has suggested that Atlantic herring (Clupea harengus) is one of the more environmentally responsible fish." 

 But what is an "environmentally responsible fish"?  Is this a fish that recycles its beer cans?  Maybe it uses some sort of composting technique to recycle its shit? 

 Or maybe the person who wrote this needs to improve his or her English language skills?
