Is running helpful or harmful?

Should we be running long distances, mileage, marathons? I personally think that the increase in cortisol stress hormone and risks on joints from running outweigh the benefits... If you stress your joints with thousands/millions of reps what impact does that have on your joints, tissues, ligaments over time? If you were to bike for 20 minutes at a slower pace (60rpm's) that would be l,200 reps... Think about doing 1200 push ups or squats... It makes you think about it differently. Me personally, I have done cardio exercise for 20+ years and it hasn't lowered my blood pressure.

Is there another way to get cardiovascular benefits without running? I believe that breathing exercises, meditation, Isometric Resistance Training can have more impact or influence than traditional cardio.
