The Future of Protein: Patrick Caughill The technology behind lab-cultured meat products is rapidly advancing. When we start seeing these kinds of products being sold right alongside their traditionally farmed cousins, we should look more at the contentious topic of the impact livestock farming has on the environment. Further, "each year 13 billion hectares of forest area are lost due to land conversion for agricultural uses as pastures or cropland, for both food and livestock feed crop production.
Lawrence THE HANDLE, which varies in length according to the height of its user, and in some cases is made by that user to his or her specifications, is like most of the other parts of the tool in that it has a name and thus a character of its own.
I call it the snath, as do most of us in the UK, though variations include the snathe, the snaithe, the snead, and the sned. Onto the snath are attached two hand grips, adjusted for the height of the user.
On the bottom of the snath is a small hole, a rubberized protector, and a metal D-ring with two hex sockets.
Into this little assemblage slides the tang of the blade. This thin crescent of steel is the fulcrum of the whole tool. From the genus blade fans out a number of ever-evolving species, each seeking out and colonizing new niches.
I also have a couple of ditch blades which, despite the name, are not used for mowing ditches in particular, but are all-purpose cutting tools that can manage anything from fine grass to tousled brambles and a bush blade, which is as thick as a billhook and can take down small trees.
These are the big mammals you can see and hear. Beneath and around them scuttle any number of harder-to-spot competitors for the summer grass, all finding their place in the ecosystem of the tool. None of them, of course, is any use at all unless it is kept sharp, really sharp: You need to take a couple of stones out into the field with you and use them regularly—every five minutes or so—to keep the edge honed.
And you need to know how to use your peening anvil, and when. When the edge of your blade thickens with overuse and oversharpening, you need to draw the edge out by peening it—cold-forging the blade with hammer and small anvil.
Probably you never master it, just as you never really master anything. That lack of mastery, and the promise of one day reaching it, is part of the complex beauty of the tool.
Etymology can be interesting. Scythe, originally rendered sithe, is an Old English word, indicating that the tool has been in use in these islands for at least a thousand years. But archaeology pushes that date much further out; Roman scythes have been found with blades nearly two meters long.
Basic, curved cutting tools for use on grass date back at least ten thousand years, to the dawn of agriculture and thus to the dawn of civilizations. Like the tool, the word, too, has older origins.
The Proto-Indo-European root of scythe is the word sek, meaning to cut, or to divide. Sek is also the root word of sickle, saw, schism, sex, and science. Some books do that, from time to time, and this is beginning to shape up as one of them.
By his own admission, his arguments are not new. But the clarity with which he makes them, and his refusal to obfuscate, are refreshing.In the history of the mankind, the need of resources was the most important factor for political, technological, economic, social evolutions.
In modern times need of energy resources become more significant than other industries who were more important during the past like the production of wood.

One thing that people who wield great power often fail to viscerally understand is what it feels like to have power wielded against you. This imbalance is the source of many of the most monstrous decisions that get made by powerful people and institutions.
THE FALSE ALLURE OF GROUP SELECTION. Human beings live in groups, are affected by the fortunes of their groups, and sometimes make sacrifices that benefit their groups. The technology behind lab-cultured meat products is rapidly advancing.
When we start seeing these kinds of products being sold right alongside their traditionally farmed cousins, we should look more at the contentious topic of the impact livestock farming has on the environment.
