One problem that we have on Mars is that there is no food for us to eat. One solution for this would be hydroponics. This is when plants are grown in a greenhouse and without soil. Then the plants can keep producing seeds and they can be used for food. This process is very helpful because you don't have to use a growing medium, such as sand or soil, and no automation, growth lamps, or electricity is needed. We will bring seed packets to grow the plants. Then the plants will be able to regrow because they produce seeds.
Another solution for this problem is to bring some animals that will be kept in a pen. The animals can be used for food as well as wool and feathers. The dome-shaped enclosure will help because it can filter out suffocating air and give the animals clean air to breathe. It will also keep animals safe from harm and will prevent them from running away.
