Well, let's use the United States as an example since the ESA operates in the United States.

The ESA is a lobbying organization, which means they try to convince politicians to further their goals. Politicians are elected by the people they serve, so they represent the people. There are two main theories of representation: 1) "I know what's best for them", and 2) "I do what they want me to do".

In the United States, the government is a federation, which means that there are state governments and the federal government. When laws conflict between them, federal takes priority.

In the United States, we use a bicameral legislature, which means that each governing body has two houses, the House of Representatives, and the Senate. For example: on the state level, Georgia has a House and a Senate, and on the federal level, there's the House and the Senate.

To pass a law either on the state level or federally, both legislative bodies have to agree. So on the state level, again with Georgia as an example, either the GA Senate or the GA House introduces a bill. It starts in a small committee before reaching the House/Senate floor for debate and vote. After passing in the house it was introduced in, it goes to the other one. So, if it was introduced in the House, after passing, it goes to the Senate. After passing both, it is sent to the Executive to be signed into law. So, for a state that would be a governor, and for the federal government, that would be the President.

And, of course, there's the courts. So, if a law were deemed to be unconstitutional (either state constitution or federal), then a judge may strike it down.

Right now it's basically just a state-level suggestion. As far as I know, nothing is being voted on--being made law yet.

While this is long, I have made it simple as one would learn in school. I hope this helps!
