Technological change appears to be a positive change for society. It improves agriculture, transportation, healthcare, industries etc., but because technological change is one of the main causes of increasing obesity. First, improvements in the agricultural sector brought about by technological change may increase the number of obese people. Due to technological change, planting, harvesting and raising animals is easier. Farmers don't have to do everything themselves, for example, they use tractors to sow seeds, instead of hiring many farmers to do it. Furthermore, nowadays, farmers use insecticides to prevent losses. Both tractors and insecticides are products that derive from technology and innovation. This is a positive change for society as the costs of agricultural products decrease. However, this is also a negative effect that makes people gain weight. A decrease in the costs of agricultural products affects a decrease in the price of food and groceries. Price is a sensitive effect for everyone because it measures the amount of money they spend on goods and services, so the change in the price of food and groceries directly affects people's consumption. If the price of food and groceries increases, people will buy less food and groceries because they have the same budget. On the other hand, if the price of food increases, people will buy more, i.e. consume more. This causes an increase in obesity. Second, technological change in the food industry creates new types of foods such as instant noodles, frozen foods, ice cream, and canned food. These foods are easy to prepare and eat, which is convenient for everyone who does not have enough time to prepare their own meal. However, this type of food is not good for your health. They include a lot of sodium, sugar, monosodium glutamate and preservatives that have negative effects on health. These foods are also high-calorie foods and cause weight gain. Third, technological change in home cooking can cause obesity. It goes hand in hand with technological change in the food industry. The example of the new technological domestic kitchen is the microwave. The microwave is easy to use, even people who don't know how to cook know how to use it. One reason that goes hand in hand with the food industry is most new types of foods use the microwave for cooking. Because it is convenient and easy to use, people can prepare meals with it several times a day. In addition, foods that can be cooked in the microwave are frozen foods and instant foods, so people who regularly use the microwave get a higher calorie intake. Fourth, other technological changes such as transportation and digital networking reduce physical activities which also cause an increase in obesity. Nowadays, people feel more comfortable because they drive from one place to other places instead of walking or cycling, even if the distance between two places is not far. Also, if they are hungry, but can't go out or are too lazy to go out, they can ask for food to be delivered. Additionally, people can shop online.
