I'm all for gardening - there's something therapeutic about seeing a plant grow and evolve over time. You can see something tangibly change over time as a result of your work, something quite rare in today's world where we spend our time on computers producing ephemeral things like files. That said, I'm completely opposed to urban food gardening (including chickens) because the land you're growing in is likely poisoned by years of urban pollution. Whatever you grow in those areas is going to bring that bad stuff along with it, which means your backyard tomatoes probably wouldn't pass FDA approval. Chickens are even worse, because they'll eat whatever's on the ground and that stuff gets into the eggs. So while it looks great on Instagram, your backyard eggs are probably full of rubber, asphalt, gasoline, plastics, and all the other stuff that's wafted into your property over the years. So anyway, by all means garden and have fun doing it, but if you haven't had your urban soil tested and verified as safe, don't eat anything that comes out of it. |
One group out in New Jersey that has a community garden in heavily polluted land uses clean straw bales as the grow medium. Those only last for two or three years. But you can grow stuff.
Regenerative and permaculture methods includes soil remediation techniques for rebuilding soil. For heavily polluted land, Dr John Todd has some remarkable methods that can remediate even places such as superfund sites, though that might not be something to DIY. Dr Todd also has a quick method for testing that doesn’t involve a lab; not comprehensive, but will get you the observation you need.
Finally, as you see from other articles including the current front page of HN — leafy veggies have been found to have tire additives. Micro plastics are found in rain amd in animals in the wild. Our planet has been so broadly polluted, and our industrial agriculture will not necessarily be safer. For those with an interest in stewardship, you have to start somewhere.
