The reality is that species migrate and certainly we can feel guilty as it was us ( the recent wave of humans) who are responsible for bringing the cat, the dog, the cane toad, the horse , the camel, the goat, the fox, the rabbit those birds..indian minor? etc to these shores but they are now part of the mix... think of the plants also that invade once they are cast out...
What can we do I ask and I doubt if there is anything that can solve this problem really... they have throw a lot of cash at getting rid of the rabbit but they are still there...
I forgot to mention the water buffalo up North..
There is one thing which could work... a bounty as when ever humans see a profit they are prepared to drive that species to extinction...
I bet if you could get $20 for a cane toad they would last about 5 years...
I think we should not be so hard on the ferals however when we can see tracts of land cleared cleared by greedy humans to be replaced with mono cultures that will not support the native species that once lived there... up home as I said there is no problem with ferals as there is plenty of turf and it is tuff to get by irrespective of being a local or an import there is enough room for all it seems but where it is desert like well one cat or one dog or one rabbit, horse or whatever will have an enormous impact..
I dont know but one thing is for sure it is humans that have created the problems with ferals and they wont do zip to really fix it...
I wonder what the planet will be like in say another 500 years at the current rate of land clearing, species extinctions and lack of care on our part... I dont think there are any bears left in the UK and they were once a native there..and wolves they are gone alsoI think... it was not the Lions the Rome let go when they left that took them out... those animals were hunted by humans.
Sadly on this planet extinction is the rule not the exception... that is the fact we who are confined to a small part of history can not comprehend... and when you look back thru history you find the percentage of extinction is (from hazy recollection) some 95% or greater.. so that leaves me to think everything is the way it is ..a sad reality that can be laid at our feet in this age..however when humans were not the main players extinctions still happened... it is sad to think we lose so many aniamls each year the curent extinction rate is unbelievable I can not recall it but maybe someone can tell us how many species disappear for good each year...
I think I will spend the rest of the day wringing my hands.
