I’d grow food. Good food, and way more than I or my family could possibly eat. I’d also grow beautiful, ecosystem-supporting native plants. I’d offer to do the same for my neighbors who dont enjoy such things, or who just want a beautiful and functional yard.

With my leftover time i’d go hiking a couple times a week, and I’d read scientific literature when the sun goes down.

Bamboo is monocarpic (true bamboo at least.). The huge clonal colony flowers once and dies, even below ground. The seeds that fall grow the next generation.

Bamboo species tend to all flower at the same time at the end of a years or decades long cycle. This bottlenecks how much it can spread clonally (underground roots) but gives it another method to spread.

Rats, mice, and other rodents eat the seeds, so there is some ecosystem regulation already

Places with good habitat but no native bamboos like Hawaii have really bad problems with colonies taking over huge areas

I’m in an area that cools down at night so i use that as much as possible:

Once daytime temps drop below indoor temps (usually late evening) i open all windows and arrange a couple fans and run them on low all night. My goal is to move all of the hot air out of the apartment and replace it with cool outdoor air.

In the morning, ideally just before sunrise, i draw most/all curtains, shutter blinds, close windows, and turn off all excess lights. During the day i keep everything closed and the air still, and use as few lights as i can manage.

I can generally maintain about 15 degrees (f) cooler indoors with this technique. I currently live on the third floor which is working against me; this was much more effective (20-25 degrees) when i lived on the ground floor.

If i leave the windows open it or worse forget to draw the blinds it gets much warmer indoors than outside. I think my building must have pretty mediocre insulation and my windows are all single-pane.
