At last some real efforts are being made by law to save wolves from mindless persecution. The US has made some really bad decisions about wolves in the past leading to almost exterminating the species for no good reason at all. Top predators are needed to maintain a balanced ecology and the existence of wolves has proven to be essential in maintaining prey species numbers. All the creatures in the wolves world have their place and are vital to a stable environment that has been proven by scientists and those that study the impact the loss of these amazing and intelligent animals has had. So often it seems humans have to nearly destroy a species before we realise the catastrophe we have caused.
