I donate blood four times a year. There are a lot of people that think I am crazy for donating. I believe and know that donating blood is very important and very necessary. I try to convince my piers to donate blood especially at our office blood drives. There is more good that comes out of donating blood than there is.
Another thought that I have is that my brother does medical research. He often does tests on small animals,Even on dogs. One experiment that he did was hipnosis on dogs in place of anasthetisia. these dogs went through their surgery wonderfully. Many animal activists would be against this type of reasearch using dogs. My brother often uses mice and other animals. I can't convince everybody that using animals for medical research is necessary but i can try to convince you.
One other thought for a topic is how they are still strip mining on and near Indian reservations and contaminating their drinking water. I was visiting on an Indian Reservation in Arizona a few years ago, they were preparing for a marathon race to protest the strip mining that was going on near their reservation. This is a topic that I never persued and would like to find out more about it and tyr to convince the government on how they are still abusing the land of the Indian.
