Terra Nova

There is a TV series of interest coming out late September called Terra Nova. Refugees from the year 2149, seeking to escape their ruined world, find a way to time travel back to prehistoric Earth and begin anew. The Earth in this future is overcrowded and overdeveloped, with most other species extinct – a scenario similar to the Avatar movie (and Stephen Lang, the actor who was “Colonel Quaritch”, is in Terra Nova also). The government of then is enforcing population control, which causes protests from silly irrational people, and one of the main families in the series who time travels has an illegal 3rd child.

Unfortunately, this seems to be again presenting population control in a negative light – as dystopian future novels or movies tend to do (see my 16/7/2009 entry), presumably so as to give their characters something to rebel against. If they had practiced population control earlier, though, perhaps the situation would not have become so dire! Despite this annoyance, I’ll probably watch the series.

Food security

Great Tully sugar sell-off proves bittersweet”, The Australian, 6/7. The topic of food security has been getting some media attention in Australia recently, due to people realizing that foreign companies are purchasing vast tracts of farmland here. This means that food grown here by them will be sent overseas. Add this to the foolish government policy of letting developers build over arable land and Australia may well have to import food for its citizens in the future.

His concern is that Australia is selling off its food-producing capacity, piece-by-piece, without thinking through the implications of what foreign ownership means. “We seem to be selling off the farm so we can go offshore ourselves,” he told The Australian. “We’ve got large superannuation funds and other funds available for investment in this country, but the people running them overlook the significant assets in this country because they think they can always get a better deal offshore. I see that as a real shame, that people overseas can see the value in our businesses and enterprises here, but we can’t seem to.”

Perhaps if the food supply situation became dire, the Government could seize the land back in the name of national security? Other countries should take responsibility for containing their own growth, not expect to keep grabbing resources from others.

A Future of Price Spikes”, Time magazine, 14/7, looks at the concern of rising food prices and says that technology has enabled Thomas Malthus’s predictions (the planet’s population grows exponentially, while food production increases arithmetically) to be staved off – for now. But rising populations and decimation of the environment are pushing technology to its limits, and the world has only about 3 month’s wheat storage in reserve should some sort of blight wipe out the world’s wheat crops (illustrating the danger of reliance upon a limited variety of food products). The article asserts that “what we need is a new green revolution” – better technology such as genetically engineering foods, hardier seeds, fairer food distribution. But the world’s population will continue to rise and environmental destruction will hamper the attempts to increase food supplies.

Little media attention was given to recent reports about human activity in the oceans – mainly overfishing and dumping waste – threatening to wipe out marine species, but the sea is another major provider of food so this is an obvious area of concern.

Famine crisis

A famine has been declared in the Horn of Africa region, due to drought (possibly climate change-related). Around 12 million people are affected. Such a disaster shows what a liability high populations become when the food supply is threatened. Imagine this happening in a developed country – say, if the food supply was cut off for some reason – and the chaos that would ensue. As I have asserted before, the only way to avoid such emergencies is to keep population growth restricted even in times of plenty when the natural instinct is to reproduce profligately (as happens in the natural world – Nature’s “boom and bust” cycle). Then if a drought comes there will be enough food to go around. Therefore the long-term aid to the affected countries should include educating women, access to family planning and medical care so their children survive to adulthood. From one of the LA Times articles linked to below:

Women who have no schooling give birth to an average of 4.5 children; with just a year or more of schooling, the number drops to 3. As education increases, the number of births drops. Girls in Africa who receive some education will have fewer children and have them later in life. Their children will be healthier, and more educated as well.

There’s a series of articles about overpopulation in the 21/7 LA Times:

Most commentators are in agreement that overpopulation is a real concern – a root cause of many of the other world’s problems – but gets little attention due to the topic being taboo. One though, Alex B. Berezow, disagrees and brings out the tired example of the problem being due to distribution not numbers. But a lot of land is unsuitable for habitation, or would require environmentally-destructive methods to make it suitable. Another has an opinion piece that bigger families are better. Maybe, if you want home-grown workers! Children in such families tend to get lost in the crowd as they recieve proportionally less attention with the more siblings they have (as some article commentators noted). I doubt there are any “good reasons” for women in developed countries to have large families; it’s just selfishness on their part.

I have read Dick Smith’s Population Crisis (reviewed at CanDoBetter) and found it an informative summary of the overpopulation issue. It is written from a layperson’s viewpoint, so is more accessible than an academic text. Possibly the only disagreement I have is his assertion that coercive methods of population control are not necessary as women “when given the choice, make sensible decisions about the size of their family”. From observation, quite a lot don’t – many Australian women seem to be having large families (three or more children).

In a book review or opinion piece (it’s not clear which) in the Australian, the reviewer dismissively remarks:

To the best of my knowledge this is the first time in history that an important scientific question is dominating national and international politics. It has occurred before but not in such a way as to permeate global awareness. For example, the fear of an all-out nuclear war, so strong in the 50s and 60s, possessed a strong scientific ingredient but the debate was generally viewed more as a military and political than a science matter. Likewise, periodic fears about overpopulation, and especially the Club of Rome’s warning in the early 70s that the world’s fast-multiplying population might soon be short of food and minerals, carried a scientific component, part of which was ultimately seen as slipshod. These fears engrossed only a small section of the population in Western nations, then they faded.

Er…no! Those fears concerning overpopulation are more acute and relevant than ever, and certainly haven’t faded.
