Achieving Sustainable Development in the Face of High Population Growth and Depletion of Natural Resources: Article Critique

“Is Humankind Dangerously Harming the Environment?” I attached two articles. One article says YES and the other says NO. 1. Need to critique both of them write one or two paragraphs about who I agree with, and then list any questions I felt were unanswered by the authors. Please use additional sources... No Wikipedia, encyclopedia, or sites similar to about.com are allowed. Teacher PREFERS academic articles such as those found through Google Scholar (scholar.google.com). Please be careful with the grammar... The last two articles I ordered had several issues and I had to spend hours correcting them.

During the last half of the twentieth century, the world economy expanded sevenfold. In 2000 alone, its growth exceeded that of the entire nineteenth century. Economic growth, now the goal of governments everywhere, has become the status quo. Stability is considered a departure from the norm.
As the economy grows, its demands are outgrowing the earth, exceeding many of the planet's natural capacities. While the world economy multiplied sevenfold in just 50 years, the earth's natural life-support systems remained essentially the same. Water use tripled, but the capacity of the hydrological system to produce fresh water through evaporation changed little. The demand for seafood increased fivefold, but the sustainable yield of oceanic fisheries was unchanged. Fossil-fuel burning raised carbon dioxide (CO2) emissions fourfold, but the capacity of
nature to absorb it changed little, leading to a buildup of CO2 in the atmosphere and a rise in the earth's temperature. As human demands surpass the earth's natural capacities, expanding food production becomes more difficult.
Losing Agricultural Momentum
Environmentalists have been saying for years that, if the environmental trends of recent decades continued, the world would one day be in trouble. What was not clear was what form the trouble would take and when it would occur. Now it has become increasingly clear that tightening food supplies will be our greatest trouble and that it will emerge within the next few years. In early 2004, China's forays into the world market to buy 8 million tons of wheat marked what could be the beginning of the global shift from an era of grain surpluses to one of grain scarcity.
World grain production is a basic indicator of dietary adequacy at the individual level and of overall food
security at the global level. After nearly tripling from 1950 to 1996, the grain harvest stayed flat for seven years in a row, through 2003, showing no increase at all. And production fell short of consumption in each of the last four of those years. The shortfalls of nearly 100 million tons in 2002 and again in 2003 were the largest on record.
Consumption exceeded production for four years, leading world grain stocks to drop to the lowest level in 30 years. The last time stocks were this low, in 1972-1974, wheat and rice prices doubled. Importing countries competed vigorously for inadequate supplies. A politics of scarcity emerged, and some countries, such as the United States, restricted exports.
In 2004, a combination of stronger grain prices at planting time and the best weather in a decade yielded a substantially larger harvest for the first time in eight years. Yet even with a harvest that was up 124 million tons from that in 2003, the world still consumed all the grain it produced, leaving none to rebuild stocks. If stocks cannot be rebuilt in a year of exceptional weather, when can they?
