Recently, there has been a genuine shortage of blood, platelets, and plasma ever since the COVID-19 pandemic. This has caused people to have to delay life-saving emergencies. This is a genuine shortage where people's lives are being affected by said shortage. Therefore, I believe it is a moral obligation to donate blood, platelets, and plasma as much as allowed by the donation center. By doing this, you are saving lives and it is pretty inexpensive and cost-effective.

Furthermore, I talked to a person who took my blood. Can't provide a source on that, but I am guessing the person who took my blood wouldn't lie just like that.
How is veganism effective then? Like blood/platelet/plasma donation is ineffective because there are already lots of blood donations out there, but somehow veganism if effective despite there being plenty of meat eaters out there?
Furthermore, earlier on regarding saving hospitals money, I have been thinking if that really saves any lives in a very indirect manner. For context, I live in the US in a for-profit healthcare system. Should I care about saving hospitals money? Who receives the benefit in this scenario? Maybe hospital has more money to save more people, or maybe the admins in charge gets a bigger payraise...
