Chongqing denies further mass relocation in Three Gorges area to save environment

A Chongqing government spokesman on Thursday denied media reports that another four million people would be relocated because of environmental problems caused by the Three Gorges project.

  Last month, China Business News quoted vice mayor of Chongqing Yu Yuanmu as saying the ecological safety of the area was at risk from the growing population.

  But spokesman Wen Tianping, speaking at a regular press conference held by the Chongqing authorities on Thursday, insisted that the plan to encourage millions to leave their homes was just part of the urbanization drive and was not a forced relocation.

  "The reports that another four million people will be moved out of the Three Gorges Reservoir area are not accurate," Wen said.

  "The municipality aims to attract three to four million people from rural to urban areas by 2020 to narrow the urban-rural wealth gap," he said.

  Another vice mayor of Chongqing Tang Xiwei said last month that the municipality''s development would focus on the areas within a radius of one hour''s drive from the downtown area.

  Chongqing plans to have 22 million residents in the area by 2020, three to four million more than the current 18 million, according to Tang.

  The area accounts for 78 percent of Chongqing''s economy volume and is expected to account for 80 percent by 2020, Tang added.

  On June 7, Chongqing and Chengdu, capital of neighboring Sichuan Province, were selected by the National Development and Reform Commission, the country''s top economic planner, as pilot cities to work towards coordinated and balanced development between urban and rural areas.

  In March 1997, the city, which sits on the upper reaches of the Yangtze River, was approved as a centrally-administered municipality, the fourth after Beijing, Shanghai and Tianjin. It was expected to spearhead economic development in China''s central and western regions.

  Covering 82,000 square kilometers, the municipality has a population of more than 27.98 million, 55 percent of whom live in rural areas.

  China has relocated 1.22 million people for the Three Gorges project so far and will have relocated nearly 1.4 million by the conclusion of the relocation process by the summer flood season next year, according to an official with the office of the Three Gorges Project Committee of the State Council.

Don’t reuse food and water containers

Do not reuse plastic food and water containers. This is the advice given by Health Minister Datuk Seri Dr Chua Soi Lek in Kuala Lumpur Malaysia.

He said this was because the quality of such products was “questionable” and Malaysians were at risk of being exposed to chemicals which might seep into the food or liquid.

“Takeaway plastic food containers used in eating outlets are disposable items and designed for single use only.

They are not intended for repeated storage of food,” he said in an interview with The Star.

Instead, Dr Chua said that people should only use reusable plastic food containers such as cups, plates, bowls, bottles and boxes used in household kitchens for repeated storage of food because these containers have attributes such as sturdiness and thermal stability.

He emphasised that takeaway food containers which were labelled “microwave safe” for reheating should not be reused.

As for mineral water plastic bottles, Dr Chua said it was not advisable to keep on reusing them.

“It is not easy to clean. You can never reach the inside and in the hot Malaysian weather, the stability is questionable,” he said.

His comments were based on a recently concluded study commissioned by the ministry to the Faculty of Medicine, Universiti Malaya, carried out by Prof Dr Mustafa Ali Mohamad.

The study showed that in 45 of the 47 containers examined, at least one chemical was detected. However, the level of the leachate detected was low.

The scope of the study was to analyse chemicals in plastic polystyrene food containers.

The chemicals analysed were styrene monomer, bisphenol A (BPA), dibutyl phthalate (DBP), benzyl butyle phthalate (BBP), di- 2-ethylexyl adipate (DEHA) and di-2-ethylhexyl phthalate (DEHP).

The samples included different types of food and water containers and were extracted at room temperature for 30 minutes.

Dr Chua said the level of chemicals was low “but you cannot rule out the small amounts excreted which will accumulate in the body.”

He cited the potential that BBP had in affecting a person’s endocrine function such as the thyroid gland and pancreas. Dr Chua also said it was safe to freeze meat directly in its original commercial plastic wrapping.

For long storage, rewrap or over-wrap the meat tightly with moisture-proof freezer bags to maintain the quality and texture of the meat, he said.

Sea levels on the rise


Over the past 30 years, temperatures in the Arctic have been creeping up, rising half a degree Celsius with attendant increases in glacial melting and decreases in sea ice.

Experts predict that at current levels of greenhouse gases-car-bon dioxide alone is at 375 parts per million-the earth may warm by as such as 35C, matching conditions roughly 130,000 years ago. Now a refined climate model is predicting, among other things, sea level rises of as much as six metres, according to research results published in the journal Science.

Modeller Bette Otto-Bliesner of the National Center for Atmospheric Research in Boulder and palaeoclimatologist Jonathan Over-peck of the University of Arizona matched results from the Community climate system Model and climate records preserved in ice cores, exposed coral reefs, fossilised pollen and the chemical makeup of shells to determine the accuracy of the computer simulation.

Roughly 130,000 years ago, the Arctic enjoyed higher levels of solar radiation, leading to increased warming in the summer and the retreat of glaciers worldwide. The model correctly predicted the extent of the resulting Arctic ice melt, enough to raise sea levels by roughly three metres.

"Getting the past climate change correct in these models gives us more confidence in their ability to predict future climate change," otto-Bliesner says.

"These ice sheets have melted before and sea levels rose. The warmth needed isn't that much above present conditions."

But sea levels rose as much as six metres 130,000 years ago and Overpeck speculates that may have been the result of additional melting in Antarctica.

After all, the ice there is not all landlocked; some rests in the ocean and a little warming in sea temperatures could melt it or pry it loose. And this time around, the warming is global, rather than concentrated in the Arctic.

"In the Antarctic, all you have to do is break up the ice sheet and float it away and that would raise the sea level," he says.

"It's just like throwing a bunch of ice cubes into a full glass of water and watching the water spill over."

Such a sea level rise would permanently inundate low-lying lands like new orleans, southern Florida, Bangladesh and the Netherlands. Already sea level rise has increased to an inch per decade, thanks to melting ice and warm water expansion, according to Overpeck.

And evidence that the Arctic is exponentially warming continues to accumulate.

Indeed, in another paper in the same issue of Science, Goran Ekstrom of Harvard University reported a marked increase in so-called glacial earthquakes-seismic events recorded throughout the world when Greenland's glaciers slip past rock-since 2002.

In fact, last year alone saw twice as many quakes as in previous years, with most of that increase coming during the summer months.

"We need to start serious measures to reduce greenhouse gases within the next decade," Overpeck says.

"If we don't do something soon, we're committed to four to six metres of sea level rise in the future.
