As fears increase that global climate change will make more land uninhabitable, experts have noticed a sharp increase in the number of 'ecomigrants' worldwide.
Excerpt: Adam Fier recently sold his home, got rid of his car and pulled his twin 6-year-old girls out of elementary school in Montgomery County.
