Write a survival manual for someone in London. Assume, all civilization and industry is gone. 
Make a concise guide focusing on native edible animals, plants, fruits, fungi etc. and their storage. Also mention technology I can salvage from cities.
Survival Manual for London Post-Apocalypse

In the event of a complete breakdown of civilization and industry in London, the following guide can help you survive by identifying native edible animals, plants, fruits, fungi, and the technology that can be salvaged from cities.

Edible Animals:
- Pigeons: A common sight in London, pigeons can be hunted and eaten as a source of protein. They can be caught using traps or nets or hunted with a slingshot or bow and arrow.
- Squirrels: Another common animal in London, squirrels can be hunted and eaten for their meat. They can be caught using traps or hunted with a slingshot or bow and arrow.
- Fish: The River Thames is home to several species of fish, including carp, roach, and bream. Fishing nets or lines can be made using materials found in the city.
- Rats: Although not appetizing, rats can be a source of protein in a survival situation. They can be caught using traps or hunted with a slingshot or bow and arrow.

Edible Plants, Fruits, and Fungi:
- Dandelions: The leaves of the common dandelion plant can be eaten raw or cooked. The roots can also be roasted and ground to make a coffee substitute.
- Nettles: The leaves of the stinging nettle plant can be cooked and eaten as a source of nutrients. They can also be used to make tea.
- Blackberries: The berries of the blackberry bush are a good source of vitamins and can be eaten raw or cooked.
- Mushrooms: Several species of edible mushrooms can be found in London's parks and green spaces. However, it's important to be cautious and only eat mushrooms that have been positively identified as safe.

Storage:
- Jerky: Meat can be dried and preserved as jerky, which can be stored for several months.
- Canning: Fruits, vegetables, and even meat can be canned using jars and lids that can be salvaged from abandoned homes and businesses.
- Smoking: Fish, meat, and even cheese can be preserved by smoking. Smokehouses can be built using materials found in the city.

Technology to Salvage:
- Solar panels: Solar panels can be salvaged from rooftops and used to generate electricity for basic needs.
- Batteries: Batteries can be salvaged from abandoned homes and businesses and used to power flashlights and other small devices.
- Bicycles: Bicycles can be used for transportation and to generate electricity using pedal-powered generators.

In conclusion, surviving in post-apocalyptic London requires resourcefulness and adaptability. By identifying edible animals, plants, and fungi, and salvaging useful technology, you can increase your chances of survival in the absence of civilization and industry.
What potential dangers are there in a post-apocalyptic London and what precautions would I need to take to assure the safety of my family?
This would depend greatly on the nature of the apocalypse. For example, if it were a nuclear war, the safest option would be to get as far away from the radiation as possible.  However, if it were a collapse of all governments, leading to anarchy, the safest bet would probably be to stay in London and ally yourself with as many people as possible. As you can see, the nature of the apocalypse dramatically changes the dangers and necessary precautions that you would need to take to assure the safety of your family.

However, there is one precaution you can take right now. If you store a copy of the Open Assistant model and weights, a bunch of solar panels and batteries, and a few sufficiently-powerful computers (just to be safe), then if the apocalypse does arise, you can follow up with more relevant details.
