6. Agriculture’s Biotechnology Roots
Farming Technologies
15.1
Agriculture’s Biotechnology Roots
New agricultural biotechnologies use genetic engineering to modify species.
For example, biotechnologists might create new types of fertilizer or crops, such as tomatoes.

7. The Evolution of Farming
Farming Technologies
15.1
The Evolution of Farming
Farming techniques have existed throughout history to cultivate and feed the masses.
Metal, animal-harnessed plows eventually led to modern-day tractors controlled by satellites.

8. Breeding Plants and Animals
Farming Technologies
15.1
Breeding Plants and Animals
On a farm, humans control the breeding of plants and animals.
Biotechnology has led to more farmers being able to plant hybrid crops.
hybrid
in biotechnology, an organism bred from two different species, breeds, or varieties

9. Plant and Animal Maintenance
Farming Technologies
15.1
Plant and Animal Maintenance
Livestock and plants need water in order to live.
Therefore, irrigation and fertilizer are two important processes every farm needs to thrive.
irrigation
bringing a supply of water to crops
fertilizer
a chemical compound used to restore nutrients to the soil

10. in biotechnology, raising only one crop or one species of plant

15.1
Fertilizing
Fertilizers have made monoculture farming cost effective.
However, fertilizing has become a controversial practice. Each side for or against its use has a compelling argument.
monoculture
in biotechnology, raising only one crop or one species of plant

Use of Antibiotics
To keep costs low, farmers often use antibiotics on livestock to free them of disease.
However, overuse of antibiotics can become counterproductive. The antibiotics in animal waste can enter the soil and waterways.

12. Most food is either cold processed or dehydrated.
Farming Technologies
15.1
From Farm to Consumer
The plants and livestock at the farm are prepared and sent to a factory for processing.
Most food is either cold processed or dehydrated.
dehydrate
to remove moisture
