Answer:worst offender, a dirty energy source that produces less than half our electricity but nearly 80 percent of all power plant carbon emissions.
The good news is that coal is on the decline. Many old and inefficient coal plants are closing down and essentially no new coal plants are being built in the US, a trend that is driving the largest transformation of the US electricity system in half a century.
The energy choices we make during this pivotal moment will carry huge consequences for our health, our climate, and our economy for decades to come.
Right now we are moving toward a natural gas-dominated electricity system, but an over-reliance on natural gas has significant risks and is not a long-term solution to our energy needs. Like coal, it is a fossil fuel that generates substantial global warming emissions, and has other health, environmental, and economic risks.
There's a better, cleaner way to meet our energy needs. Renewable energy resources like wind and solar power generate electricity with little or no pollution and global warming emissions—and could reliably and affordably provide up to 40 percent of US electricity by 2030, and 80 percent by 2050.
To create a cleaner, safer, and healthier energy future, it's time to choose renewables first.

Answer:
San Martin did just that, securing Argentinian independence and liberating Chile and Peru from Spanish rule in part through a daring march across the Andes. Though he met with Simon Bolivar, liberator of several northern South American countries, they were unable to agree to greater cooperation.
The main issue is still occurring today and so it was mainly getting jobs to provide for their families, themselves, and their families back in mexico, so since Mexicans were illegal immigrants (aliens), they couldn't get jobs easily as us, they had to go through a lot of work and become a legal citizen to get a job, and even today Mexicans still have hard times working since the U.S. is not accepting as many immigrants anymore.
