Economic botany is a field of science that focuses on how plants can be useful for people. It primarily deals with how plants are useful for human welfare - as food, clothing, shelter and medicine, which are used directly or indirectly.
Diversity in living organisms
Indirect usage includes the needs of man's livestock and the maintenance of the environment. The direct benefits may be commercial, domestic, environmental, or also can be aesthetic.
Plants are useful for the country's economy to a great extent. It is also noted that a country's wealth depends mostly upon agriculture and plant products.
Economic botany is the study of the relationship between people and plants and the usefulness of plants in the economy.
Rice, wheat, and millets have been the staple foods of the Indian population seen in ancient times. Evidence includes the presence of charred grains in the excavation sites. In addition, abundant information is available in ancient literature about the existence and usage of several crops that are of economic importance.
Uses of plants to humans:
Plants provide oxygen (\(O_2\)) through the process of photosynthesis that is used for respiration by humans and other animals.
Plants are great contributors to the economy of a nation.
Economic plants can be utilised directly (in food) or indirectly (products that satisfy the need of humans' livestock and the maintenance of the environment) for humans' benefit.
