Have you got any life hacks to reduce our footprints on this globe? Anything that's ecologically friendly and it can be anything that you care to share ..
In the winter I don't want to cover all of the windows with plastic, so I cut cardboard to fit the ones I don't, and use it to insulate the glass at night. I left tabs to make it easier to put up and take down. If it's very cold at night, I have to move the plants off the sill, so I'm at the window anyway...
If you have a window you don't look out of, ( ...

or don't want anyone looking in!) cover the cardboard with something black and leave it up all the time. The black will absorb any heat from the sun and help to heat the house.
The same way people are warmer in layers, if it's going to be
very cold that night, I'll throw a sheet over my curtains. That extra layer on cold nights helps save energy.
I don't do this... but you can also keep your house warmer by hanging cloth "wall art" of some sort in winter. Castles used tapestries, but I've seen it nicely done with an area rug, and also a handmade quilt on a frame.
I also use less energy (electric) to heat the house in the winter simply by hanging a curtain on a tension rod between the living room and the rest of the house. This keeps my living room 5-10 degrees warmer than the rest of the house, so I can set the thermostat lower.
The house is built long and narrow, with the front door in the middle, in a small entryway. The living room is to one side, the kitchen and bathroom are to the other. The front door is metal, with a large window in it, and it
radiates cold in the winter. For some reason, they put the thermostat on the wall across from the front door.
The bathroom and kitchen
are chillier, but if I'm spending any amount of time in those rooms, it usually involves heat.
