Invasive species

Recently I was reading an article about how they were putting poison in a river to kill carp, an invasive species from Japan, that was taking over. Then a few days later I saw another article about kudzu. Another invasive species from Japan that is being furiously torn down and sprayed to try to keep under control.
The common characteristic between kudzu and the carp is that they are Japanese. The Japanese are putting these problems, the invasive species, on our land that we then have to poison. This will continue to happen. Its like spraying for ants. You have to spray the scout ant or else they keep coming. The only possible solution to this problem is to poison all the Japanese instead of simply their species. This will stop the spread of any unwanted species around the world. And help solve the population crisis. So many problems solved with one simple solution.

*Obviously I do not believe we should actually kill all the Japanese.*
