I don't need to, the predictions debunk themselves by not coming true. Every other greeny has made a prediction ever since Malthus in the 1800s and they have all been wrong.
Welcome to economics and individual wealth. China is buying more because it has more money. Want everyone to be fed? Convert to socialism, any other way is impossible - even if abundance existed.
I see, so you're still relying on making predictions eh? You do realise that the malnourished population has stayed steady at 900 million since the late 60s, right?
China's farmland has shrunk by 8.33 million hectares in the past 12 years, Chen Xiwen, the top agriculture adviser to the Premier, Wen Jiabao, said last year. Land under cultivation has fallen almost to the government's 120 million-hectare limit after being covered by apartments and factories, lost to desertification and used for a forestation campaign.
Do yourself a favour and read that. Again.
China's ability to produce her own food has been hampered by growth. As it is, no more than an estimated 8 - 10% of China's land is arable anyway. China outsources her food demands, which is fine. For now. What happens if and when the world reaches the point China is at, when the demands of the global community exceeds available supply? Wide open land does not equate to arable land and often you'll find it is wide open for a reason; ie, economically unviable.
Lets not forget about fresh drinking water. And oil. And timber. And coal. And, and, and. . . Resources are limited and most are not replenishable. Our needs are not limited, to the contrary, our needs grow continually.
Population explosion necessitates more housing. Population explosion necessitates more jobs. Population explosion necessitates more food. More housing requires more land. More jobs mean more factories/office blocks which require land. More food means more land needs to be converted into farming land. As previously and undeniably proven, not every inch of vacant land is arable, so on that final point, you will reach a point where there is no more land left to farm on without completely destroying the environment around you.
When meeting the above needs (food, housing, industrial) environmental destruction occurs as well as the collateral damage to biodiversity. Environmental destruction can and does have an impact on humans, such as accelerating soil erosion and increasing the chances of disasters such as flooding and land slides.
Not to mention pollution and human waste. Our waste, for the most part, is not biodegradable and once it is exposed to the environemt - pollution - it does considerable damage. Ironically, a major form of that damage affects one of our limited and most vital resouces - water.
