In the context of discussing putting something into the ocean, using the example of "lots of water" being toxic is somewhat... amusing. Given that copper is unambiguously a nutrient for life, I'd like to see a mechanism for how it would be excessively concentrated in places other than where it is directly being used before I get too concerned. In general, "in the ocean" is what I'd reach for as my example of where it is very difficult for something water-soluable to end up concentrating unexpectedly. Copper is something we put in multivitamins, on purpose. You can buy copper supplements for your cattle: https://www.jefferspet.com/products/copasure https://www.jefferspet.com/products/copasure You can read about how to rectify copper deficiencies in your garden soil, as well as the signs you've got too much: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/copper-for-the-garden.htm https://www.gardeningknowhow.com/garden-how-to/soil-fertiliz... "Copper = poison" is an oversimplification, in a way that "Lead = poison" isn't.

  Since the subject of context has come up - in the context of water-living invertebrates, copper is poisonous in anything other than very low concentrations. This is why copper containing solutions are used to kill snail and slug infestations in aquariums, gardens and elsewhere. Not sure why there is any confusion about this. Any aquarium keeper for example, knows to avoid copper religiously if keeping inverts.

Yes, tomatoes are poisonous (a relative of the nightshade) but you'd sooner drown in all the tomato juice you'd have to consume.

  I think the vines and leaves are the parts to worry about, but even then it's not as bad as the more toxic members of the nightshade family.
