GM TRIUMPH IN AUSTRALIA

Farmers have begun harvesting a vast crop of genetically modified cotton that has allowed them to slash the heavy use of pesticides for which they have long been been criticised. With NSW and Queensland farmers free for the first time last spring to plant as much GM cotton as they liked after nine years of caution, about 80 per cent of the 300,000 hectares sown was genetically modified to resist herbicides and fight the crop's enemy, the helicoverpa moth.

While cotton growers such as Bourke's Ian Cole would normally spray his crop up to 18 times each growing season to kill off pest insects, this season he only sprayed three times after choosing to grow a GM crop. Those three sprays were targeted to attack sucking insects such as mites and did not wipe out the "beneficials" - spiders, wasps and ladybirds - as the powerful, broad-spectrum sprays for helicoverpa used to. "I'm a big believer in technology being able to solve problems for us in agriculture," Mr Cole said. "Technology has solved a huge problem for us in cotton."

Over the years, traditional pesticides had became stronger and were applied more frequently as insects built immunity. Helicoverpa moths lay their eggs into the boll, or fruit, of the cotton plants and when the larvae hatch they eat the fruit.

GM pioneer Monsanto first won permission for Australian farmers to grow its Ingard GM cotton in 1996. Ingard contained a gene found in soil bacteria that enabled the cotton to produce a protein that killed the grubs when they ate the plant. But because there was a risk of the helicoverpa developing immunity to the single-gene product, planting of Ingard was limited to 30 per cent.

Now Monsanto has replaced Ingard with Bollgard II, which uses two genes and produces two deadly proteins. The chance of insects developing immunity to Bollgard is "extremely small", according to Mark Buckingham, a Monsanto spokesman. Ingard enabled farmers to more than halve the amount of pesticide spraying they needed to do and Bollgard requires 85 per cent less pesticide than conventional cotton.

As an ongoing safeguard, farmers planting Bollgard must also plant a "refuge crop" of pigeon pea. The theory is that any moths that do develop an immunity to Bollgard would mate with moths that have fed on the nearby pigeon pea and have not developed immunity. Their offspring would also not have immunity.

Apart from carnations, cotton is still the only GM crop allowed to be commercially grown in Australia because of strict government regulations and strident opposition from environmental and consumer groups.

Mr Cole said that as well as being great for the environment and the workplace safety of his staff, Bollgard saved farmers a lot of money because they do not have to spray as much and can devote more time to other matters such as improving water efficiency. Cotton's thirst for water is the industry's other public relations problem.

Globally, the area planted with GM crops rose 20 per cent last year to 81 million hectares - 5 per cent of the Earth's cultivated crop land. More than 8 million farmers in 17 countries planted GM crops in 2004 and 90 per cent were in developing countries. When commercial GM crops were first planted in 1996, there were 1.7 million hectares.

ANOTHER COMMMENT ON THE LATEST "RUNNING OUT" SCARE

Excerpt from Cafe Hayek. See also my comment of April 1

"Look at that last item again:

Deforestation and other changes could increase the risks of malaria and cholera, and open the way for new and so far unknown disease to emerge.


That is not science. That's scare-mongering. Or wild-guessing. Or something else. But it's not science. Is that from the journalist or the report? Alas, it's more or less from the report. Here's how the press release words it:

The degradation of ecosystem services could grow significantly worse during the first half of this century and is a barrier to achieving the UN Millennium Development Goals. In all the four plausible futures explored by the scientists, they project progress in eliminating hunger, but at far slower rates than needed to halve number of people suffering from hunger by 2015. Experts warn that changes in ecosystems such as deforestation influence the abundance of human pathogens such as malaria and cholera, as well as the risk of emergence of new diseases. Malaria, for example, accounts for 11 percent of the disease burden in Africa and had it been eliminated 35 years ago, the continent's gross domestic product would have increased by $100 billion.


When you read the actual press release rather than the news story, you realize that we've left the realm of science and are somewhere else. 'Could grow worse.' 'Four plausible futures.' (Only four?) And they're worried about malaria's impact on GDP? But we could have saved millions of lives from death by malaria by using DDT. But that's bad for the environment. So is that good or bad?

Look at the first two items:

Because of human demand for food, fresh water, timber, fibre and fuel, more land has been claimed for agriculture in the last 60 years than in the 18th and 19th centuries combined.

An estimated 24% of the Earth's land surface is now cultivated.


Sounds scary. But why go back 60 years? Is 24% the critical number where the whole system is going to collapse? Why? Where's the evidence? I'm trying to find a reliable source on the web for what has happened since 1960. Most sources suggest that land under cultivation has risen from 1.3 billion hectares in 1960 to about 1.4 billion hectares today. (In the meanwhile, I'm searching for a reliable link.) If true, not so scary.

Water could be a problem down the road. It's a problem now around the world due to poorly run thugocracies around the world, but that's not what the report is referring to. The world's fisheries are probably mismanaged. But where's the evidence that we're standing on the edge of a precipice? There isn't any.

I plan to sleep well tonight, though I am worried about the state of science.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
