Immigration has become the main issue for Trump. The first thing to remember Donald is population growth. In my life it’s gone from less than 4 billion to now more than 8. Soon enough there won’t be enough land for all in adequate places with the necessary services. Also humans want to survive persecution. “America First” should now become “Humanity First”. Immigration and global warming are big issues facing humanity right now. Perhaps as leader of the free world you must also be humanitarian. Indeed pretty soon we will need solutions to these problems. I think global warming the most pressing but that will solve immigration, there won’t be humans anymore.
