Allowing lawn fertilizer to run off into street storm drains is the biggest observable impact on my local watershed.  Being in Florida, this in turn flows out to sea impacting ocean waters as well.  Improvement will come from education and informing neighbors about where those street drains lead to ultimately.

Yes, bundling and scheduling errands to make the most efficient use of driving.

Continuing down the path of light bulb conversion as existing ones burn out.  Also, use of more timers so nighttime lighting doesn't stay on whilst almost everyone is sleeping.

I hadn't heard of silvopasture before this exercise, but it is a concept that seems very old and forgotten until recently.  Only very rarely in the distant past did humans clear-cut areas, seems only logical that the shade provided would only help the grazers and overall ecology.

Although each of the listed resources plays a roll in the need to reduce food waste, for me, the greatest reason is opportunity loss.  When throwing away food that could have gone to a food bank or other place to help fulfill a basic need, an opportunity has been squandered.

My wife just reminded me that we've been eating vegetables from the "farm box" we bought at the farm of a local group - they pivoted from mainly supplying restaurants to selling boxes directly to people during COVID (when most restaurants were closed or at minimal capacity).  They still sell boxes directly, but only on certain weekend days now.  Quality was incredible. 

Eating without electronic distractions gives a moment to pause and reflect.  Sometimes about work, more often about a broader topic of interest.  It is like a mini-reset that allows me to re-imagine the possible solutions to items I'm working on.

I eat a mostly vegetarian diet - when I do eat fish, I try to buy 'wild caught' varieties. If this is not available, I will opt out and stick with a veggie dish!

There are quite a few additional R's I use, just about daily:

Repair - First try to repair something before replacement.

Rot - I compost all kitchen scrap plant matter and egg shells, been doing this for years.

Recover - I use the composted matter for soil when planting adding those rich nutrients back into the ecosystem.
