Green revolution , great increase in production of food grains especially wheat and rice that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the midth century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.

Advantage and disadvantages of green revolution
Most farmers, these days, practice modern farming methods under Green Revolution, which is a movement pushed by the government as an alternative solution to traditional agriculture. Its main goal is to make planting and harvesting more effective and efficient, as well as to eliminate hunger all over the world. It originated from manufacturers in the US when they discovered that it is possible to create a fertilizer from petroleum that can be used on crops—the so-called petrochemical fertilizer. Under Green Revolution, machinery processes are being used in farming. This modern method is seen as labor intensive, where farmers make use of tractors, instead of oxen and horses, to plow and cultivate their lands, making the process faster and easier. It is a combination of controlling chemicals in the soil, weeds and pests, mechanization of agriculture, and genetic adaptation of plants to suit daily needs. However, this method has become a subject of some debates on whether it really does good, rather than bad, for all of us.
What is the Green Revolution? The Green Revolution is the term used to describe the transformation in agricultural practices in many parts of the developing world between and the s. This revolution sought to eradicate famine in many nations and massively increase food production, by effectively ending subsistence agriculture and replacing it with commercial agriculture. The idea was to transplant many of the systems, ideas and technology of Western farming into mainly Asian agriculture, whilst researching and utilising the resources Asian countries had. It was largely funded by the Rockefeller foundation , the Ford foundation and some other major agencies. USAID became involved by subsidising infrastructure developments and fertiliser shipments.

Impact of Green Revolution
The result of this information transfer to the agricultural industries resulted in a significant increase in production around the world, with an emphasis on heightened productivity in developing countries. The Green Revolution resulted in the creation of high-yielding crops, with notable improvements in rice and wheat, along with the use of controlled water supplies, chemical fertilizers, and agriculture-based chemicals to enhance the growing process. There were also new methods of cultivation introduced during this time, including mechanization, that superseded the traditional technologies that were used in the past. Today, the Gates Foundation is attempting to make it work in Africa. We can certainly feed more people and produce higher yields with greater consistency because of the Green Revolution, but there are some serious and major disadvantages that we must consider as well when looking at this important part of human history.

Meaning of Green Revolution
Беккер не мог исчезнуть, тем более так. Халохот оглядел дворик. Он. Он должен быть. Дворик под названием Апельсиновый сад прославился благодаря двум десяткам апельсиновых деревьев, которые приобрели в городе известность как место рождения английского мармелада. В XVI11 веке некий английский купец приобрел у севильской церкви три десятка бушелей апельсинов и, привезя их в Лондон, обнаружил, что фрукты горькие и несъедобные. Он попытался сделать из апельсиновой кожуры джем, но чтобы можно было взять его в рот, в него пришлось добавить огромное количество сахара.
Так появился апельсиновый мармелад.
Даже клочка бумаги. - Где теперь это кольцо? - спросил Беккер. Лейтенант глубоко затянулся. - Долгая история.
Да, - сказал голос. - Мой человек ликвидировал его, но не получил ключ. За секунду до смерти Танкадо успел отдать его какому-то туристу. - Это возмутительно! - взорвался Нуматака. - Каким же образом вы выполните обещание об эксклюзивном… - Не волнуйтесь, - спокойно ответил американец.
