As a persistent warmist surely you know the basic fact that increasing co2 has a strong greenhouse effect that increases crop production.
Consequently agricultural yields have increased massively over the last twenty years and satellite photos globally show an increased greening of the planet of approx 10%.
Below just one of thousands of articles that corroborate this fact.
Executive summary World agriculture towards2015/2030
In recent years the growth rates of world agricultural production and crop yields have slowed. This has raised fears that the world may not be able to grow enough food and other commodities to ensure that future populations are adequately fed.
However, the slowdown has occurred not because of shortages of land or water but rather because demand for agricultural products has also slowed. This is mainly because world population growth rates have been declining since the late 1960s, and fairly high levels of food consumption per person are now being reached in many countries, beyond which further rises will be limited. But it is also the case that a stubbornly high share of the world's population remains in absolute poverty and so lacks the necessary income to translate its needs into effective demand.
As a result, the growth in world demand for agricultural products is expected to fall from an average 2.2 percent a year over the past 30 years to 1.5 percent a year for the next 30. In developing countries the slowdown will be more dramatic, from 3.7 percent to 2 percent, partly as a result of China having passed the phase of rapid growth in its demand for food.
This study suggests that world agricultural production can grow in line with demand, provided that the necessary national and international policies to promote agriculture are put in place. Global shortages are unlikely, but serious problems already exist at national and local levels and may worsen unless focused efforts are made. Food and nutrition
Massive strides have been made in improving food security. The proportion of people living in developing countries with average food intakes below 2 200 kcal per day fell from 57 percent in 1964-66 to just 10 percent in 1997-99. Yet 776 million people in developing countries remain undernourished -about one person in six.
Global progress in nutrition is expected to continue, in parallel with a reduction in poverty as projected by the World Bank. The incidence of under-nourishment should fall from 17 percent of the population of developing countries at present to 11 percent in 2015 and just 6 percent in 2030. By 2030, three-quarters of the population of the developing world could be living in countries where less than 5 percent of people are undernourished. Less than 8 percent live in such countries at present.
Despite impressive reductions in the proportion of undernourished, continuing population growth means that progress in reducing the total number will be slower. The World Food Summit of 1996 set a target of halving the number of undernourished people to about 410 million by 2015. This study's projections suggest that this may be difficult to achieve: some 610 million people could still be undernourished in that year, and even by 2030 about 440 million undernourished may remain. Priority for local food production and reduced inequality of access to food could improve this performance. The problem of undernourishment will tend to become more tractable and easier to address through policy interventions, both national and international, as the number of countries with high incidence declines.
