Or imagine a future with plentiful food and fuel crops.
Through improved seed stocks and more efficient water management, we can have crops that require less water, grow at higher density, and thrive in wider temperature ranges.
But it also includes choices made on a much smaller scale: farmers pondering which crops to plant, how much fertilizer to apply, and when and where to sell their produce.
Worldwide, one-third of all crops are wasted.
Meanwhile, vertical farm experiments – which aim to augment urban food supplies by cultivating crops in skyscraper greenhouses – are proliferating from the American Midwest to Osaka, Japan.
Agriculture, predominantly subsistence farming, employs over 60% of the African workforce, implying widespread destruction of livelihoods, to say nothing of increased food insecurity as crops are disrupted.
The rise of carbon dioxide in the atmosphere B which is the main cause of the long-term climate change B might actually have some directly beneficial effects, since a higher concentration of carbon dioxide can stimulate the faster growth of some types of forests and some crops.
Northern regions, for example, could enjoy a longer growing season for some crops, while more Southerly regions, which are already hot, might suffer from the adverse effects of rising temperatures.
These so-called "wars" are part of the same conflict that prompted the peasant blockades of September 2000, the continuing protests by coca growers against efforts to eradicate their crops because of their role in the cocaine trade, and the withdrawal earlier this year of a progressive tax project.

More recently, scientists have developed techniques that take this process a step further, using genetic engineering to induce agricultural crops to synthesize high-value pharmaceuticals.
In 2003, the US Department of Agriculture announced onerous new rules for testing crops engineered to produce pharmaceuticals.
The ostensible objective of the regulation is to avoid contaminating food supplies with drugs, especially when edible crops are used to produce them.
In fact, even if biopharmed plants were to contaminate food crops, the likelihood that consumers would end up with harmful amounts of prescription drugs in their corn flakes, pasta, or tofu is very small.
Gene flow is an age-old process that is well understood by farmers, who grow hundreds of crops, virtually all of which have been genetically improved in some way with a variety of techniques.

The planet’s biomass – forests, pastureland, savannas, and crops – make up productive capital that generates a 10% “return” every year.
Thus, “energy crops” could be developed to produce biofuel.
However, in many places, energy cropping would certainly compete with food crops.
One reason is that such crops rely on research tools used in molecular biology, including genetic engineering.
Fourth, pollen from GM crops may “contaminate” organically produced food.
Similarly, a large share of farmers – most of them smallholders – in Argentina, Brazil, South Africa, China, India, and other countries, prefer GM seed because they make more money from the resulting crops.
Finally, it is often claimed that GM crops simply mean costlier seeds and less money for farmers.
The root of the problem is that Africa’s farmers are too poor to obtain the basic modern inputs—including high-yield seed varieties, fertilizers, and small-scale water management systems—that could enable them to double or triple their output of food and cash crops.
Beginning in 1930, some 1.3 million people starved in Kazakhstan as their meager crops were requisitioned according to central directives.
Dying peasants harvested the spring crops under watchtowers.
According to recent research, if the world stopped producing crops for animal feed or diverting them to biofuels, it could not only end global hunger, but also feed four billion extra people – more than the number of projected arrivals before the global population stabilizes.
The famines in Ireland in the nineteenth century and in Ethiopia in the late twentieth century provide clear evidence of the vulnerability of undiversified crops to environmental changes, and the dramatic consequences of such vulnerability for the population.
Access to market information, for example, can ensure that farmers selling their surplus crops are not cheated by unscrupulous traders, and that fishermen can land their catch at the port offering the best price.
Yet one cannot rule out the possibility that genes for female sterility could find their way into species that pollinate crops or serve as a food source for birds, reptiles, and even humans.
