Hi, and welcome to week six. Now this week is a new week that we've added as a result of realizing that perhaps we hadn't properly addressed some of the naughtier issues. That are associated with the use of animals. And we decided that week six should be a week that is not obligatory, there's no test or quizzes involved with this. It's purely for the interest of those people who would like to learn a little bit more about the issues. And also the welfare research that's associated with animals and their slaughter. And also the use of animals in research. Now we realized that there's quite a lot of ethical concerns about the consumption of animals. And of course the process of getting animals to slaughter. And also the use of animals in research. And some of those have come up all ready in the discussion forums. What we do not want to do is to enter into discussions about the ethical use of animals or the consumption of animals. And we'll leave that for you to decide and to discuss. What we do want to be able to do is to provide you with some of the objective studies. Some of the studies that have looked specifically at the welfare issues for these different species. Recognizing that there are many, many millions of animals that are slaughtered. And that are used in research every year throughout the world. What we do want to do is give you a real flavor of the kind of research that's going on, and there's a huge amount of research. And also of the different controls, the different legislation and the different policies that govern the use of animals in research. But also, try to improve standards for animal welfare. I want you to enter into this week with quite an open mind. There's some things that you will find, I''m sure disturbing. We've tried to signpost those so that there's little bits of film that we think you might find disturbing. We've given you choices about whether you want to look at those films. And we want you to engage with the material in the order that we've presented it. So that you can get a really good overview of what we believe the welfare issues are. And the research that is being done to address those issues. I hope that you find this week six interesting, informative, and engaging. And I'm sure that at the end of it, you will feel that you will be in a much better, stronger position to make evidence-based arguments. About whatever your ethical position might be. Thank you very much.
