This means that although for hundreds, perhaps thousands of years, people have lived in those forests, or whatever habitat it is, in harmony with their world, just killing the animals they need for themselves and their families, now, suddenly, because of the roads, the hunters can go in from the towns.
Esto significa que aunque durante cientos, tal vez miles de años, ha vivido gente en esas selvas, o el hábitat que sea, en harmonía con su mundo, sólo matando a los animales que necesitan para el consumo familiar, ahora, repentinamente, gracias a los caminos, los cazadores pueden entrar desde los pueblos.
