I fail to see what karma has to do with anything. If you only participate in charity because you might need charity as well some day… Well, in my book that’s more selfish than my point of view.
And how do you define a just cause anyway? Is it a just cause to support some people with food, water, medicine, etc just so they can stay alive and nothing else? Or do you honestly believe that your givings, along with the givings of any other self proclaimed saint, will change the way those people have been living so far? Do you think that your givings will result in the creation of job possibilities, result in a better life, of a better government?
And to change the subject to something closer to home. Some 8 year old child has an aggressive cancer (or any fatal disease). Why would I donate money to the family of that child? You might say that it could be spent on research and development of a treatment, but do you honestly believe that the companies performing said R&D don’t have the funds? They have more than enough money, and odds are they already have a treatment for that cancer, but they’re just in in the process of testing it and getting it approved. That 8 year old child is already sentenced to death and won’t be cured, and future patients may or may not be cured, regardless of how much money we sent to the family to support “Little Timmy’s Charity Fund against Cancer and other Bad things”.
My brother has a form of Becker’s Muscle Dystrophy, and his type may not be lethal, he’s in a wheelchair and he does need help in an hourly basis (pouring him some coffee, for example). I’ll gladly help him and his friends with anything they may need when I’m around, but why should I send money to organizations or scientists that are working on a cure or treatment? We know they’re working on it, and even if they figure one out right now, it’ll still be another 4-5 years before it gets on the market. That’s how it goes. Money won’t change any of that.
And about those animals. I’m a firm believer in the law of nature and evolution. If animal species are getting extinct because of human wrong doing, then (in my eyes) that’s part of the evolutionary cycle. Humans are part of nature, everything we do will affect other creatures, just like army ants, just like lions, just like any living thing on this planet. Now, you may say that what humans do is “too much”, that we “fish way more than what we need”, and that’s probably true, but I see that as a treat if the human race, just like how destroying any wildlife they can handle in certain areas is the treat of an army ant. If you don’t keep the rabbit population in check, nature in that area will suffer greatly as well (and certain species of animals in that area won’t survive). Humans are animals, and just like any other animal, our actions have effect on the rest of the planet. If that effect is the extinction of animals, so be it. I don’t like it and I hate to see it happen, but I sure as hell won’t give an organization any money so they can rent a boat and stick and go poke some Japanese whalehunters.
