S. 3840 is a bill that wants to change a law so that big stock markets can't trade parts of companies that look after nature, like taking care of forests or keeping animals safe. This is to make sure nature isn't harmed when trying to make it more valuable.

The Protect America’s Lands Act is a rule that says places where people trade stocks can't trade stocks from businesses that take care of nature, like forests or rivers, by keeping them healthy and safe. It's like a rule saying if you run a lemonade stand to help a garden, you can't sell lemonade tickets in places where everyone trades other tickets.
