What is the first green revolution and what is the second green revolution?

The first green revolution took place in the early 1950s. Its main feature is to change the tall stalks of rice into short stalks, supplemented by pesticides and agricultural machinery, thus solving the problem of food self-sufficiency in 19 developing countries. In some countries in the world, the contribution rate of science and technology to agricultural growth is generally above 70%. For a country that is extremely short of water like Israel, the contribution rate of science and technology to agriculture is above 90%.

The second green revolution means that through the joint efforts of the international community, modern biotechnology with genetic engineering as the core is used to cultivate new varieties and functional strains of plants and animals with high yield and rich nutrition, which will promote the revolutionary change of agricultural production mode, promote agricultural production and grain growth, and ensure the sustainable development of the environment.

Extended data:

In the mid-20th century, some developed countries and many developing countries, such as Mexico, Philippines, India, Pakistan and so on. Developing and popularizing high-yield new varieties such as rice, wheat and corn by using dwarf genes, aiming at solving the food problem in developing countries.

At that time, some people thought that this reform had a far-reaching impact on world agricultural production, just like the industrial revolution caused by steam engines in Europe in the18th century, so it was called the "first green revolution". However, this reform activity exposed many defects in the future: high technical and economic requirements, high cost, and difficult to popularize; Serious pollution, energy waste, etc.

In recent years, the United States and other western developed countries have begun to apply biotechnology and microelectronics technology to transform traditional agricultural production, which is called "the second green revolution".
