US-Mexico border wall poses severe environmental threat
Bulldozers are clearing the way to build a new wall on the border between Mexico and the United States.
The wall is a $5bn commitment by US President Donald Trump to stop asylum seekers getting into the US.
But experts say the environmental cost of the wall may be enormous too, as well as irreversible.

Reason editor-in-chief Katherine Mangu-Ward shares her insights on the federal government's attempt to seize private land through eminent domain for the US-Mexico border wall. United States President Donald Trump's border wall has secured $1.3bn in funding, under a government spending package signed last week.
The barrier dividing the US and Mexico is well behind schedule, but it is breaking ground in Arizona, one of the most biologically diverse parts of the country.
The environmental cost of this may be irreversible.
Al Jazeera's Rob Reynolds reports from near Sonoyta, Mexico. Construction on United States President Donald Trump's border wall with Mexico is moving ahead.
In Arizona, parts of the barrier will cut through sites considered sacred to some Native American tribes.
But tribal elders say they will not let that happen without a fight.
