I first applied to doctoral programs in 2010 for a 2011 start. I was finishing my masters from NYU (which I hadn't really stressed about getting into), I only applied to four schools, interviewed at one of them. Denied from all of them.
Now, I had worked for 4 years before doing my masters, so I was already on a career path that I could return to, but I think the answer is the same.
You do something else. You intern. You volunteer. You get a job. I believe the statistic is that under 2% of people in the US get PhDs. That's a lot of people doing something else.
The first point would be if you are still in school, go talk to your career center. Every school has one. Just go and talk with an open mind about what's out there. Anthropology and Environmental Public Health? You could look at government jobs or corporate jobs that have an environmental component. Or non-profits that work in environmental policy. Or any job that requires a clear and cogent writer. You have experience with children and tutoring? Look at the 826's in various cities.
Rather than a specific field, ask yourself what you like to do during the day. Is it writing? Is it working with a team? Is it a job that you spend 8 hours doing and then leave or do you want to have a job that has flexible hours? Those answers will guide you as you look at options.
Me? I connected my career with my interest in education and worked as staff in academia for three years before applying for PhDs again.
