In 2013, United Nations Food and Agricultural Organization released a report “Edible X: Future prospects for food and feed security”. It talks about X being a very efficient method of turning various forms of vegetable matter into proteins: we do better eating X that has eaten the grass than we would eating the grass directly. What was the report recommending we eat?

Insects "Common prejudice against eating insects is not justified from a nutritional point of view," write the authors of a 191-page report. World population is slated to top nine billion by 2050, and seeing as how arable land is being rapidly swallowed by towns and cities, oceans are increasingly overfished, and climate change is disrupting traditional farming, a new United Nations study proposes a twist on Marie Antoinette's dietary advice: let them eat bugs.

In the early to mid 19th century, multiple advances in the field of agricultural machinery were made more or less in parallel by inventors in Scotland, the US, and Australia, all working (mostly) independently of each other. These developments coalesced into a single large, complex, and massively convenient piece of farming equipment that went through several stages of evolution, first horse-drawn, then steam-powered, then tractor-drawn, and eventually fully self-propelled and self-contained, complete with cameras and sophisticated yield monitoring and field mapping systems.
At its core, this machine merges the farming tasks of reaping, threshing, gathering, and winnowing grain into a single activity, and is commonly known by a deceptively simple name.
