Coastal erosion is a problem in many countries, and the UK is firmly in that list. When I was in school there was a lot of study of sea defences and erosion protection, and pretty much no consensus on what would actually help, apart from "stop building houses even remotely near cliffs".
Now, a years-long experiment to halt (or at least slow) erosion has concluded - and their method? Dump a load of sand in front of the thing you want to protect, in this case a rather difficult-to-move gas terminal. Well, scientifically dump, there is an actual process here!
Did it work? Well, it mostly seems like it did - good news for the gas terminal, or at least for the next fifteen years, as that's how long the solution will last. It won't work everywhere - coasts vary wildly - but hopefully, it might help save a bit more land from the ever-encroaching sea.
The USA is a bit of a conundrum when it comes to rail - a vast network that was built at great (human) expense during the frontier years, and which arguably was the backbone of travel and commerce, but which is now mostly used for freight - albeit a lot of it.
Analysing why Americans really don't use trains is something that happens on the regular, but this article hits some good points - including the current big-two problems of zoning and frequency. Worth a read if you want a bit more insight into what it might take to bring the US some actually-modern passenger rail.
When you own a bit of forest, you want to look after it the best you can. Cut down old trees, plant new ones, and figure out how to make the forest look visually appealing in the process. But what if you have a clear-cut area of land that overlooks a highway that you, say, want to be a bit more interesting than normal forest?
In Oregon, someone did just that. They planted two different species of trees in the shape of a giant smiley face - and while most of the year you can maybe make it out if you squint, come autumn, the two species of trees go different colours and bam, giant face staring down at Highway 18 in Yamhill County.
I think more forests could do with trees being planted in very strange shapes. Just don't spell out HELP by planting brand new trees - by the time it's visible, I imagine it'll be too late.
