Rig, I'll bet a lot of those who are screaming loudest about illegal immigrants and how they destroy our environment are among the majority Americans who
1) contribute to rampant environmental devastation via overconsumption (plus not reusing or recycling),
2) insist on buying low-cost produce (picked by immigrants who will work for slave wages) or goods manufactured in 3rd world countries that protect neither workers' rights nor the environment,
or both.
