Killing large and small animals (defaunation) is seriously affecting humans’ health and well being, through a negative affect on agriculture and increased occurrences of animal-human disease transmission. Ebola and many other serious diseases have appeared as a result of increased contact with wild animals. Large scale hunting and anthropogenic transformation of natural habitats together with climate change is increasing animal-human disease transfer. More:

But nobody ever talks about the diseases humans may transmit to wildlife!
we are one big disease to other animals and the planet
Agree 100%!!!Thank you.xxx
Good point, mankind is a scourge, a plague a pox on nature.
And human activities spread extant diseases back to the animal world
Here’s something that humans have spread to animals, and I believe TB in cattle was spread to them by humans. So we’re not as pure as the driven snow, as some would like to believe:
Can humans spread diseases to animals?
Yes. Globalisation and industrialisation are causing diseases to spread from humans to animals, according to a 2008 study that found a form of the bacteria Staphylococcus aureus in chickens originally came from humans.
The study, published in the Proceedings of the National Academy of Sciences, reports to be the first bacterial pathogens crossing over from humans to animals and then spreading since animals were first domesticated some 10,000 years ago.

And you can probably get rabies from the anti-wolf screechers. 🙂
