Not just obesity. Black women are, by far, more likely than any other racial group to get abortions. Every single time one is performed, it damages the uterus, and increases the risks of miscarriage while decreasing the chances of successful pregnancies.

I've also heard from multiple sources that the experimental Wu Flu injections cause increased rates of miscarriages and pregnancy complications, but I don't think I've ever seen a conclusive research on the subject. Though that probably doesn't mean much, considering that all studies critical of the jabs have obviously been censored and discouraged for over two years, now.
