We briefly review the feedback effects of massive stars, via their stellar winds and supernova explosions, on the star-forming regions in which they were born. We give a few examples, spanning a wide range of spatial scales, from ∼100 pc out to ∼10 kpc: the so-called “Local Bubble” (in reality an open bipolar structure extending on both sides of the galactic disk); the Extended Orion Nebula and its open cavity filled with a hot, MK outflowing plasma; the Great Carina Nebula and its extended diffuse X-ray emission; the 30 Dor region in the LMC and its various bubbles; and the extended, bipolar outflow of the prototype starburst galaxy M 82, influenced by a nearby group of galaxies. We conclude by stressing the similarity of these phenomena across all spatial scales, galactic and extragalactic.
