The role of plants and animals in human life.

The role of plants and animals in human life:
1. Food. Many plants, their berries, and root crops are eaten by humans. Parts of animals, as well as their waste products (milk, eggs) are also food for humans.
2. Plants saturate the atmosphere with the oxygen necessary for breathing.
3. Manufacturing. Parts of plants are used in the manufacture of fabrics, dyes, food processing, etc. And parts of animals are used in the manufacture of leather.
4. The sanitary role of plants. Some plant species (conifers) release phytoncides into the air, which have antimicrobial and antibacterial properties.
5. Medicine. Both plants and animals are used in medicine. For example, badger fat or plant pollen.
But plants and animals can also play a negative role in human life. These are poisonous plants or wild animals, or animals that carry diseases.
