Programmers are the greatest browsing community (SO mostly)…We can singlehandedly save the planet.
sustainability as a concept done on an individual basis shouldn’t be framed as planet saving because it’s. not. you can’t save the earth by planting your own tomatoes, because the destruction of the earth is due to corporations
what you CAN do is use individual sustainability to gain a level of independence from capitalism for yourself and for your community through things like sharing grown food
What if, instead of tropical fish tanks, you had a live video stream of a section of coral reef? Every time you “fed” the fish, it would be a button you clicked to donate to the reef’s protection. As more you “feed” the fish, you’re granted more access to other reefs. And nightvision cameras are included so you can see your wild pets at night too without disturbing them with harsh lighting.
Perfect for folks like me who love fish, but do not love cleaning tanks.
What do you think of vertical axis wind turbines? Seems to me they'd complement small domestic PV installations nicely and could use some wider usage
I’ve heard some people get quite preachy about vertical axis wind turbines being no good, but personally I’m rather fond of them. I definitely agree that for domestic use, they make more sense than regular windmills. They’re also much better suited to urban environments.
The typical style of wind turbines are great when you have lamellar flowing air currents, like near the coast or on flat plains, but city wind is more gusty and turbulent. Vertical axis turbines definitely seem ideal for that!
I think some of the reservations people have stem from the fact that, in the past, vertical axis wind turbines have typically been less reliable, and the turbine blades are more prone to fatigue. Though using modern engineering materials and turbine designs, I’m not convinced those old problems still apply.
Some designs for small scale applications are also impressively discreet and quiet – though seemingly rather expensive!
earlier this month it was 120 degrees in Australia , but yeah lets continue to mock those trying to save us in the 12 years we have left to slow climate change’s effects.
What is the worst thing that could happen if we listen to scientists and change our ways, and then it turns out they were lying?
Slowly dying in a mad max hell world to own the libs I guess.
But seriously, when we got our property, it was all just…grass. A sterile grass moonscape, like a billion other yards. With two big old maple trees. Just grass and maples, that was it.
But then I got my grubby little paws on it, and I immediately stopped fertilizing, spraying, and bagging up grass clippings and leaves. I ripped up sod and put in flowers and vegetables. I put down nice thick blankets of mulch around the flowers and vegetables.
When I first was sweating my way through stripping sod, I saw a grand total of 1 worm and 0 ladybugs. The ground was compacted into something that would bend shovel blades.
Now, six years later, I can’t dig a planting hole without turning up fourteen earthworms, and there are so many ladybugs here. Not the invasive asian lady beetles; native ladybugs. They winter over in the mulch and in the brush pile. I see thousands of them.
The soil is soft and rich. There are birds that come to eat, and bees of many sorts.
Like this is something that you, yourself, can absolutely change. This is something that you, personally, can make a difference in.
Blue Pixie’s Parasol (Mycena Interrupta) or subspecies.
Mycena interrupta, commonly known as the pixie’s parasol, is a species of mushroom. It has a Gondwanan distribution pattern, being found in Australia, New Zealand, New Caledonia and Chile. In Australia it is found in Victoria, Tasmania, New South Wales, and South Australia, and in Queensland where its distribution is limited to Lamington National Park. Description The caps of Mycena interrupta range from 0.8 to 2 cm, and they are a brilliant cyan blue colour. They are globose when emergent and then become a broad convex as they mature, with the centre of the cap slightly depressed. The caps are often sticky and appear slimy looking, particularly in moist weather.

Solar Pines by HG-Architecture
A rest area for city parks, which doubles as a solar collector generating up to 1.2 kW per hour. At night, it uses collected solar energy for illumination. It’s like the sun jar, except you can sit inside it and eat your lunch!

Most plants can be grown from cuttings meaning that, if you know what you’re doing, they’re a great way to rapidly grow a whole garden full of plants. Or a whole house full, if you’d prefer.
The simplest type are stem cuttings, but many plants can be regrown from other parts like leaves or roots too. As long as there are stem cells in the cutting it’s possible to, with some care, regrow a full plant. In practice, how easy this is depends on the specific plant – but it never hurts to try!
So here are a bunch of how-to resources for anyone who wants to know more.

Some plants which grow well from stem cuttings
Here are some random ideas of things to do with cuttings…
Buy a rose bush. The good ones like damask roses can be expensive, but that’s ok. Prune it extensively and plant the stems as cuttings. You’ll soon have a whole host of rose bushes! The same thing goes for any other bush or tree. Plant yourself an apple orchard or a raspberry grove!
Buy fresh herbs. Cook with the leaves. Save aside the stems. Grow them as cuttings. Create a herb garden in your windowsill.
Going out for a walk? Carry a small jar in your bag with some damp tissue in the bottom, and a small pair of study scissors. If you see any wild plants or trees you like the look of, snip off a small stem (from somewhere discrete!) and keep it in the jar. Grow it as a cutting when you get home. (Note: I’d advise against doing this in gardens, parks, or other privately owned areas. Technically, that’s theft.)
Grow kitchen scraps.
When you buy potatoes, check them for sprouts. Sprouting potatoes can be cut up into pieces, so each piece has at least one sprout or eye. Leave them overnight to dry off a little, then plant them. Soon you’ll have a whole potato patch. Just like Mark Watney.
If a friend has an interesting plant in their garden/home/office/wherever, ask them if you can take a small cutting. Most people won’t mind.
If there are trees or shrubs in your garden, you’ll probably need to prune them occasionally. Grow the pruned stems and branches as hardwood cuttings. If you don’t have space for more trees in your garden, they make good gifts once they’re established.
