Many attempts have been made to try and control the spread of aquatic invasive species and not went as well as intended, one of which being legislative doctrines such as the Lacey Act. These doctrines, the Lacey Act in particular, have proved to be quite ineffective. This is not only because the Lacey Act lists a mere nineteen species, but also because most of the species listed were already established in North America at the time when they were included in the Act. Congress apparently takes much too long a time when passing new amendments to the Lacey Act to make it an effective doctrine. This is why targeting the invasive species problem on the trade regulation level is a more effective path.
Stricter food and drug trade regulation laws with other countries seem to be one of the best methods to go about solving the aquatic invasive species problem. Many people oppose the inspection of each ship that comes into North American ports because it is relatively costly. However, it seems to be the safest route, since according to Lodge’s lecture nearly every port in the world is connected to a body as small as the Great Lakes by only four degrees of separation. This means that, due to the incredible connectedness of the world’s shipping industry, any single port can feasibly receive goods from nearly any other port on the planet Earth! For this reason, it does not seem as if one could possibly classify any water body as a “danger zone” since the world’s ports are apparently so connected. Therefore, it appears that, although costly, more rigid trade inspection and regulation laws are necessary, even if it means the inspection of every ship that comes into North American ports.
