For starters, why take the life of any other living creature?

As for killing any of the mentioned, what would be the purpose?

Dingoes are and have been poached by order of the Queensland government because they are becoming too use to human contact due to illegal feeding and a an influx in tourism.A few years back , one mauled a small boy camping on Fraser Island to death. Now this is not the dingoes fault, it is humans encroaching on the dingoes natural habitat, it is tourism being greedy and building big resorts on the only place in the world where pure dingoes live(Fraser Island), all the rest of the dingo population is only 20% real dingo, they have been mixed with domestic dogs.They are not aggressive unless threatened or very hungry. They are going hungry because they have less and less natural food supply and habitat. Snakes are also not aggressive unless you step on them, go into their habitat during mating season, they pretty much leave us alone. As for skin, why don't we dry your skin out and make a bag or two out of it.crocodiles are a protected species in Australia, so go ahead and kill them and you will not only be breaking the law, you are damaging an important part of the biodiversity in Australia. An if your not Australian or don't know anything about these wonderful creatures, then best you don't try and argue on line.
