If you think about the oil slicks that we saw before, or those massive algal blooms, what you really want to do is put your Row-bot out there, and it eats up all of those pollutions, and then you have to go collect them.
Se pensarmos sobre as manchas de óleo que vimos antes, ou a proliferação massiva de algas, o ideal seria colocar o Row-bot lá pra que ele comesse toda aquela poluição, e então precisaríamos buscá-lo.
