Agriculture

• The designing of tractors, combine harvesters and other farming equipment have helped tremendously in the farm industry.

• Crop yields have been improved and more nutritious foods have also been produced since the introduction of agro-chemicals.

• Animal production (in terms of meat, milk, hide etc) has been improved because of the practice of irrigation farming and the invention of drugs to fight diseases that affect farm animals.

• Proper methods of preserving food such as canning and refrigeration for a long time have also brought about large-scale production of food.

• Genetically modified foods have also produced other varieties of crops.
