Husband is bringing me down

Currently 5+5. My hubby and I worked so hard to get pregnant, including a miscarriage in august and multiple IUI cycles with injectables. We are both thrilled to be pregnant, and he has been super interested in all appointments and getting the house ready for the baby. However, for the last 2 days, he has been obsessed with reading a ton of news articles, all about how the world is going to shit in various ways (war, global warming, food and gas prices, how we are becoming a corporatocracy instead of democracy, etc). Anyway, he has been talking about how irresponsible it probably is that we are having a child given the state of things. I mean, I agree that there are real problems in the world, but he is making it hard to be joyful instead of anxious.
