Overview:  AI will demand a huge jump in power needs. Interconnection (tying into the grid) is a 3-5 year wait. Renewable co-located with existing gas plants can use the existing interconnection in place.
Takeaway:  Gas plants are more often used for “peak” demand, and the less we use them, the better off we'll be from a global warming point of view. Because the list of pending projects, including new gas plants, is so long, renewables will save the day in the meantime if we can accelerate connection. 

Overview:  Recycling is rare for plastics: 9% of total is recycled at all.
Takeaway:  Given concerns about the health impacts of microplastics in general that end up in our bodies and brain with negative impacts, and misconception about recycling, we all need to be trying to reduce our dependence on single use plastics.

Overview:  See above for the reason to replace plastics. Seaweed (Kelp is an example) grows very fast and can replace some plastics.
Takeaway: Nature's secret weapon - meet Notpla. (credit to Javier Gascon - LinkedIn)
a) Extract compounds from seaweed that grows 30x faster than land plants
b) Create packaging that dissolves like a fruit peel
c) Make it vanish in your home compost in weeks
d) Design it to work in existing factories
 

The impact? Mind-blowing:
↳ 16 million plastic items eliminated (and counting)
↳ 90% lower social + environmental costs
↳ First packaging certified plastic-free by EU
↳ Seaweed captures carbon 20x faster than trees
Sometimes the best packaging is the kind that disappears completely 🌿

Overview:  Recurring excessive heat, 90 degrees + can have a detrimental effect on aging, particularly of older people. Up to 14 months beyond chronological age.
Takeaway:  Lack of clean air and water, heat and pollution are just a few of the drivers for negative health impacts associated with climate change and a warming planet.

Overview:  Heating plant waste at high temperatures produce valuable soil additives that both store carbon and increase fertility of land
Takeaway:  This natural solution deployed in the Amazon doesn't get enough press. Not only does the modern process create heat for use as electricity, the byproducts have enormous value.

Takeaway:  Remember Vol. 1 - composting? Think about whether you'll eat it before you buy - I'm the worst about this, but I'm working on it.
