[Back to Physical Challenges]
This is clearly a massive topic.
Because there are no clear boundaries, this topic will cover not only farming, but all use of the land to deliberately grow things or raise animals.
Growing Things for Food
There is a significant move away from raising animals to eat and towards growing plants to eat, but the issue is not a simple 'plants: good; animals: bad' one. To give one obvioous example, you can raise sheep on hill farms which occupy land which cannot be used to grow crops.
Growing Things for Materials
There is a great deal of experimentation with new materials, such as using mushrooms to replace plastic or leather. MycoAudio use mushrooms to build loudspeakers.
Plantd aim to use grass instead of wood to produce carbon-negative construction material, which is energy-efficient and uses 1/9 the amount of land.
