By 2050, the world population will have grown to 9.6 billion people - 2.6 billion more than today. At the same time, growing middle class members in India and China are already eating more meat than ever.
The Earth population is growing in the most inconvenient time. To prevent global warming, the humanity should have more land to cultivate raw materials for biofuels. At the same
time, cutting down forests to provide more land for agriculture is impossible - and so
the planet is choking with greenhouse gas emissions, in the last year they broke
all records. To feed additional mouths, farmers must increase productivity. But not
everything is so simple. Cereal production should be increased by half, that there would be no
lack of food. In 40-year time there will not be enough of it. Scientists note that the growth
in crop yields is not the same throughout the world. For example, in some parts
of India and Eastern Europe the yield has not been increasing for many years. Ниже надо перефразировать – затруднено понимание смысла. In many parts of the world, the increase in performance is not due to insufficient
investment in agriculture. Even where the service delivered to farmers all the
achievements of science, improve performance more than a certain level will not
work, because nature does not allow to grow in one area over a certain amount
of grain.
