There are a number of ways that technology can increase the amount of food available. One way is through more efficient agricultural practices. This can include using precision agriculture to more accurately target watering and fertilizing, using genetically modified crops that are more resistant to pests and disease, and utilizing technology to automate tasks like planting and harvesting.
Another way that technology can increase the amount of food available is by reducing food waste. This can be done through things like better food storage and packaging, using expiration date sensors to let people know when food is going bad, and developing apps to help people donate or sell food that they won't be able to eat.
Finally, technology can also help to increase the amount of food available by making it easier for people to grow their own food. This can be done through things like automated indoor gardening systems and home composting systems.
