Over-fishing is a real problem in the modern world. A lot of fish is used for the production of protein, to be used for instance as food for animals. That protein can be obtained from another unexpected source: insects. There are about 1400 edible insects in the world. To name a few: crickets, cockroaches, worms, fruit flies, moths… Are you still there? These insects can produce high quality protein, suitable for humans as well. Europeans currently refuse to eat insects, but Africans and Asian do. Insects are cold-blooded so they don not need food to keep their body temperature high.
A big plus of insect farming: no harmful methane production. Operating farm temperature: 28 degrees Celsius. Regarding efficiency:
Insects are nutrient efficient compared to other meat sources… For every 100 grams of substance crickets contain 12.9 grams of protein, 121 calories, and 5.5 grams of fat. Beef contains more protein containing 23.5 grams in 100 grams of substance, but also has roughly 3 times the calories, and four times the amount of fat as crickets do in 100 grams. So, per 100 grams of substance, crickets contain only half the nutrients of beef
Farming method (crickets):
Crickets are usually housed in small (4′ x 8′) containers, furnished with simple items like egg cartons to provide shelter. Heat is a necessity for breeding crickets as they require temperatures around 90° Fahrenheit. House crickets live up to about eight weeks. Until they are twenty days old they are fed high protein animal feed, most commonly chicken feed, that contains between 14% and 20% protein. In the days before harvesting the crickets at around forty to fifty days old, they are often fed various vegetables, fruits and other plant matter. This is done to improve the taste of the insects and reduce the use of expensive, high protein animal feed. Crickets are normally killed by deep freezing, where they feel no pain and are sedated before neurological death. In some parts of the world crickets are baked or boiled.

The video claims this is the world’s first automatic asparagus harvesting robot, developed in Heeze, the Netherlands. It takes 60-75 pair of hands to harvest a field of 40 Hectare. In the Netherlands the work is often done by Poles or Romanians. This practice could soon be history. Perhaps the future unemployed from Eastern-Europe use their knowledge to begin asparagus farming at home.

Asparagus harvesting the old way:
Vertical farming is the practice of producing food in vertically stacked layers, such as in a skyscraper, used warehouse, or shipping container. The modern ideas of vertical farming use indoor farming techniques and controlled-environment agriculture (CEA) technology, where all environmental factors can be controlled. These facilities utilize artificial control of light, environmental control (humidity, temperature, gases…) and fertigation. Some vertical farms use techniques similar to greenhouses, where natural sunlight can be augmented with artificial lighting and metal reflectors
The concepts was pioneered first in 2014, with Vertical Fresh Farms operating in Buffalo, NY/USA, specializing in a wide variety of salad greens, herbs, and sprouts.
Vertical Fresh Farms has been farming commercially on a small scale in Buffalo, New York for a few years, but a larger scale commercial facility is currently under construction in the Netherlands. Fruit and vegetables supplier Staay Food Group is erecting a 900 square meter vertical farm, which will have a total cultivation area of 30,000 square meters.
