1. Technology: biological cultivation

Technology supporting life and society · Solving problems with cultivation · Technology for future society

Technology That Supports Life and Society – Technology is a tool plus know-how that solves a problem. Two big areas: growing living things (crops, animals, fish) by managing light, water, temperature and food; and converting energy (electricity into motion or heat) using circuits and mechanisms such as motors and gears. Good technology is planned, checked, used safely and kept in good repair.
Appropriate Technology – Appropriate technology is a tool or method that fits the people, place and money it is used for. It is usually simple, affordable, easy to repair locally and kind to the environment. The best technology is not always the newest or biggest. We choose by checking cost, skills, repair, energy, environment and how much is needed.

Nutrition – Nutrition is how we get and use the substances in food. The body needs six groups of nutrients: carbohydrates and fats (mainly energy), proteins (growth and repair), vitamins and minerals (small amounts to keep the body working), and water, plus fibre for healthy digestion. Carbohydrate and protein give about 17 kJ per gram, fat about 37 kJ per gram. A balanced diet gives all nutrients in the right amounts, and energy in should roughly equal energy out.
