What do we know about heavy metals in soil? What do we know about lead exposure through soil and garden plants? What do we know about cadmium and arsenic in soils? What can I do if I’m at risk for heavy metals in my garden soil?
Q: My backyard got invaded by gophers (or someone who enjoys making holes). I'm worrying that I might injure myself in the holes. I have tried setting traps, but have been unsuccessful. I heard some snakes can kill gophers, but I'm also aware not to release invasive creatures. What do you recommend?
