Nine milu deer babies were born in Daqing Mountain National Nature Reserve in April, after 27 deer were relocated in September from two reserves in Nanhaizi, Beijing, and Dafeng, Jiangsu Province.

The milu deer have been brought back from the edge of complete extinction in China since the mid-1980s. The National Forestry and Grassland Administration launched the ambitious conservation program in 2019 to expand the habitat of the species. Experts came to the Daqing nature reserve for inspection, and an area with plenty of food and water was chosen to release (放养) the deer.

For Ma, who works at the Daqing Mountain National Nature Reserve’s management station, it is a new responsibility, but he remains undiscouraged by challenges. He consults experts to understand the species better. According to his observations, the two groups of animals from Nanhaizi and Dafeng are getting along well, and even integrating into one close community. Ma keeps a record of the reserve’s ecological conditions. He has noticed that the plant cover has increased, thanks to the national protection policy and plenty of rainfall in recent years.

“The milu originally lived in the wetlands along the Yellow River and the Yangtze River. This is the first time they have been released in a cold mountainous region, where the winter temperature can drop to -30℃,” says Khorintavan, head of the nature reserve. “The staff had built winter shelters, but the deer never went there. The milu deer have a thick coat, which keeps them warm.” he adds. “The task ahead is to see how well the babies adapt to the new environment.”

The gold and iron mines in the mountains were shut down long ago. Locals are aware of the importance of wildlife conservation, which has enhanced the confidence of experts.

“The birth of babies means that the Daqing Mountain National Nature Reserve is a suitable habitat for the milu deer. It is a reference for us to better develop more potential habitats,” says Guo Qingyun, associate research fellow at the Beijing Milu Ecological Research Center in Nanhaizi.

“Developed and developing nations can learn from each other seeking a low­carbon economy，” a Chinese government official said in Shanghai yesterday.

“China doesn't lag developed nations in terms of energy saving and green economy，”   said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.

“While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation，” Zhou said in a speech during the new Path of China's Industrialization forum at the ongoing China International Industry Fair 2009.

He said industrialized nations and China are dealing with different issues to combat climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions.For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized.

As such, overseas exhibitors at this year's fair are showing ways to help China achieve low­carbon emissions in the industrial section.

Swiss power and automation technology group ABB called for a stronger focus on product life cycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling.

Tobias Becker, head of ABB's process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.

LCA shows that industrial customers should focus on a product's environmental impact throughout its life cycle instead of on its initial investment or ready to use stage.For example, a motor's initial investment accounts for only 3 percent of its life cycle cost, while 94 percent goes to fuel consumption and the rest to maintenance.

Richard Hausmann, North East Asia CEO of Siemens, said：“The color of future industrialization is green.”

The Germany Company recently announces that it wants to receive orders worth more than 6 billion Euros (D|S 8.8 billion) for intelligent net power networks, Smart Grid, over the next five years.Siemens has set a 20 percent market share target for the global smart grid business.

A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability.The United States and China are considered the two biggest markets for smart grid.

After nearly 70 years of space exploration, Earth is now surrounded by space junk. Recently, an accident made the cleanup more difficult to start.

According to the European Space Agency (ESA) , scientists plan on testing their “junk truck”, ClearSpace-1, in 2025. It’s a spacecraft with four arms that can catch debris (碎片) and bring it back to Earth. They have chosen to bring back VESPA, a 113-kilogram, two-meter-wide rocket part. However, in August, it was hit by another piece of space junk, creating new pieces. The ESA is now revising its cleanup plan.

Most satellites today are sent into Earth’s low orbit, which reaches up to around 2, 000 kilometers above the Earth. There, spacecraft are most likely to crash with each other. There may be as many as 170 million pieces of space junk in orbit. Big or small, any of the pieces can cause harm to a spacecraft.

In terms of the cleanup, scientists have some other ideas. One popular plan is to equip a spacecraft with harpoons (叉) and magnets (磁铁) . The craft would shoot the harpoon to stick into the debris before “throwing” it back to Earth. Magnets could move the debris, changing its direction. The debris would burn after entering Earth’s atmosphere so there wouldn’t be much left when it reaches Earth. Scientists are also considering shooting lasers (激光) from spacecraft to heat up the debris’ surface, creating a small push that would change the debris’ orbit. This change would allow the debris to be caught by Earth’s gravity.

Space junk can be very dangerous, and space agencies around the world are testing and planning the cleanup. But why haven’t they done anything yet? One reason is the expense.

It would take between $4, 000 and $60, 000 per kilogram to catch one piece of debris larger than 10 cm. And around $300 million is needed to develop the laser technology.
