There are about 2000 wild tiger left, I found this article from 2011 saying that they might be extinct in the wild by 2030.

So there might be 2000 ecological niches for smilodon to fill in 5 years. We better hurry then.

• Step 1: acquire genetic material
• Step 2: supplement material with closely related extant species <- We are here
• Step 3: Get an egg cell with your Frankenstein-DNA to survive and divide
• Step 4: Produce a healthy baby
• Step 5: Get a small population in a Zoo/Park
• Step 6: have a permanent wild population in a specific area
• Step 7: have enough of those areas to declare repopulation a success

Is fixating on the mammoths here first-world centrism? The article mentions 4 other species that have way better chances. Also, given how far we are from actual wild mammoths, that “it can solve climate change” argument is just wrong the way it’s been presented.

I don’t think this is applicable to backyard aquaponics. You don’t want to include an anaerobic digestion plant in your backyard project.

Either you have no use for the Bio-Gas, or you use more than 10kg of fish can produce.
