So just as we manage national parks, where we promote the growth of some species and we inhibit the growth of others, we're working towards thinking about buildings using an ecosystem framework where we can promote the kinds of microbes that we want to have indoors.
Así que ó igual que controlamos os parques nacionais, onde estimulamos o crecemento dalgunhas especies e dificultamos o crecemento doutras, estamos a traballar en vista a que nos edificios se empregue un modelo de ecosistema onde poidamos estimular os tipos de microbios que queremos nos interiores.
