The Buttercup Weeds (Closest I can match to my sample) are taking over my lawn. What is the best weed killer to use that is not harmful to the environment?

There are several weeds blooming now, or about to bloom--such as buttercups--that have yellow buttercup-type blooms. So we can't say exactly which one you have, and that will determine how to get rid of it.
If possible, please attach photos with the flowers to a reply to this email.
You can also look at this in our weeds gallery: https://extension.umd.edu/hgic/topics/spring-weeds Click on Lesser Celanadine. This is a non-native invasive weed, also called fig buttercup. It's impossible to dig out once it gets established. You can use the chemical spray given, but the plant must be growing actively for it to work.
Here is the bulbous buttercup, which often gets in lawns, too: https://extension.umd.edu/hgic/topics/buttercup-bulbous This one can pull easily when the soil is wet, but be sure to get the "bulb."
Send photos if you have any doubt.
