A comprehensive report by WorldFish Center and Conservation International states that aquaculture is less damaging to the environment and more efficient than the production of livestock such as cows and pigs.

Research headed by the U.S. National Center for Atmospheric Research has found that paved roads in coastal cities, like Houston, Texas, create less breezes, which makes it more difficult for pollution to blow out to sea and away from such areas. The result: more pollution.

The Chinese news agency Xinhau is reporting that China is expanding its nationwide ban on free plastic shopping bags to minimize the 'white pollution'. This seems to be a good policy for all countries, including the United States and Australia.

Scientists are planning to dig a really deep hole through the Earth's crust and into its mantle. The start of this mega-deep hole will be made under the ocean off the coast of Costa Rica, and scientists hope to return never-before-taken samples from Earth's mantle.

Understanding how climate change could impact on the deterioration of the basic building block of much of Australia's infrastructure - concrete - is crucial to ensuring major assets such as roads, ports and buildings continue to perform up to expectations, according to a CSIRO report.
