When the trunk of my tree snapped, I taped it back together. Months later, the break had healed. How did the tree repair itself?

The trunk of a small fir tree in my garden broke, and the tree fell over. More in hope than expectation I pulled the top part back up, taped the halves back together, and screwed in metal plates to hold them in place.

To my amazement the tree survived and, months later, when I removed the tape and the plates, the break had healed and the trunk was whole again. How do trees repair such trauma? Can all tree species do it?

What is the optimum tree planting density for biomass accumulation (carbon sequestration)? For example, oak trees planted at a wide spacing tend to grow broad and massive, whereas if closely spaced they are more spindly, but there are far more of them per hectare.

Is Lithium Peroxide an alternative to trees?

Lithium Peroxide has the capability to take in Carbon Dioxide and give out Oxygen. How much Lithium Peroxide would I need to perform the same job as a tree, and could it be regenerated (from Lithium Carbonate) to keep doing it, and would it be worth it in energy costs? Could it save the planet from climate change? Should we just plant more trees?

How many trees to offset global warming? Is global warming just an indicator of a lack of trees? All the old phots i look at have LOADS of trees, locking carbon into wood, where are they now? How many would we need to plant? Should this be the first an immediate thing to complete, as the gains are incremental as the trees grow?

What caused this tree resin to first flow out at an angle, then vertically downwards, then in an upward curve? What caused this tree resin, emerging where a branch was sawn off, to flow out at an angle, then vertically downwards, before flowing in an upward curve (see photo)?
