Running leads to injury?

The whole notion of running is bad

1. First, it seems a lot of people run “exercise“; why not just walk instead?
2. The second point; people want to run to get their “heart rate“ up. Why not lift weights instead, or just sprint for short periods of time and distances? Better to increase your heart rate by 1000% for 30 seconds, rather than have your heart rate be at 125% for five hours.
3. Some people run to “lose weight“; but the real goal here is to lose fat, not “weight”. Running doesn’t cause you to lose fats; way to lose that is through intermittent fasting, no breakfast no lunch only dinner, and also by quitting all sugars starches fruits vegetables etc. 100% carnivore diet.
4. Some people run because it is free; but then again anyone who is serious about running will sooner or later drop two to $300 on shoes, therefore this logic is poor.
