I disagree.
The green revolution was all about science – the sorts of science that do not need trillion dollar budgets. In fact, agricultural science is, arguably, amongst the oldest of all – having its origins in the Neolithic period. (I guess physics always ‘wins’ – I’m guessing the lever, for example, goes all the way back to the Lower Palaeolithic.)
I have heard/read (but I cannot cite sources) that, right now, in 2008, in China, alone, there is more agricultural research and development underway than has been done in all of human history – everywhere.*
I’m also guessing that, if even 1% of that R&D is actually worthwhile, another green revolution is inevitable.
Malthus was wrong because he failed to assign a value to human ingenuity and progress and then factor that into h,is calculations. Prof. Zerker falls into the same trap: “things” are bad, right now, they may even get worse but, over the past 10,000+ years, we have demonstrated a consistent ability to solve problems and avert disasters. I see nothing in 21st century humanity to suggest that ability has, suddenly, disappeared.

* I think that estimate was based on assigning some R&D value to everything from the domestication of the first goat around 11,000 years ago through to e.g. the invention of Roundup™ circa 1970 and assigning related values to the work being done on (agriculture – broadly defined) by scholars (MSc and above) in China, right now. I have no way of knowing how valid those data might be. But, add India and Europe and America into that mix and imagine how much new work is being done!

Malthus was right

It may be time to bring Thomas Malthus back from the dead -- intellectually speaking. Believe it or not, the 18th-century thinker has a lot to say to us about problems that are here and now: population increase and the food needed to deal with it.
Malthus saw the 18th-century phenomenon of continuous population increase as a threat to human civilization. Left unchecked, be believed, populations would double themselves every 25 years, a growth rate that would quickly outstrip the available food supply. This Malthusian idea soon took on the mantra of certainty: Unlimited population growth could only end in disastrous famines and starvation.
This was a widely held belief throughout the 19th century and the early decades of the 20th century. Since the mid-20th century, however, Malthus' theories have lost credibility because the world has experienced (seemingly) unchecked population growth without the dismal result he predicted. Here we are in the first decade of the 21st century, with a world population of 6.6 billion --about six times what it was in Malthus' era -- and yet we're not starving. Malthus must have been wrong.
Or was he?
Until now, technological improvements have caused food supply to increase along with population growth -- something Malthus admittedly did not foresee. But as demand bumps up against supply, the green revolution may be over.
In recent months, food prices have risen dramatically and suddenly. In the past year, the price of wheat is up 120%. The cost of cooking oil, rice and other staples have doubled since January. For the 1.5-billion people who live on less than $2 a day, food typically accounts for almost all of their meager budget. Soaring food prices represent a calamity for these people, which explains
At current inflated prices, we can expect outright starvation in the poorer regions of the world why food riots have broken out across the globe.
A significant factor straining the food supply is the entry into the market of large middle-class populations in China and India -- people who want to live (and eat) like North Americans and Europeans. Higher incomes in these nations have resulted in increased consumption of meat, chicken and other protein foods, all of which strain grain supplies. (It takes four pounds of grain to make one pound of meat.) The formerly poor are no longer content to eat rice, bread and lentils.
During the 20th century, food production generally was not a restrictive factor on population growth. But that was during a period when only one-sixth of the Earth's inhabitants had incomes high enough to make them gluttons. This low ratio of rich to poor left enough of the pie for meager but sufficient distribution to the rest of the world.
In other words, the world seems to have avoided Malthus' dismal outcome only because the vast majority of humanity did not eat well. They were able to eat amounts sufficient to procreate and have their offspring survive, but not enough to enjoy the health-giving effect of a high protein diet.
That global social division between rich and poor is undergoing a shift, and it is one that has the potential for unleashing a massive humanitarian crisis. Malthus may yet be vindicated.
