How did invasive species get to the US?

Invasive species are primarily spread by human activities, often unintentionally. People, and the goods we use, travel around the world very quickly, and they often carry uninvited species with them. Ships can carry aquatic organisms in their ballast water, while smaller boats may carry them on their propellers.

Where do introduced species come from?

Humans are most often directly responsible for introducing a species to a new region, whether intentionally or unintentionally. Species can become unintentionally transported globally, by catching a ride in places like ship ballast water, or locally, by attaching to boats or other equipment used by anglers and hunters.

Who regulates invasive species in the US?

Are humans invasive?

1) An invasive species is widespread: Humans, which can be found on every continent, floating on every ocean and even circling the skies above certainly meet this aspect of invasiveness. 2) An invasive species has to be a non-native: Humans had colonized every continent but Antarctica by about 15,000 years ago.

Why you should never release pets into the wild?

The harsh reality is that the vast majority of released pets will die when left to fend for themselves outside.

Either way, it is extremely cruel to abandon a pet in the wild.
