1 . The second little pig was unlucky. He built his house from sticks, which was blown away by a wolf. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by an agent for the construction industry, strongly favoring brick, concrete and steel. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.
No other building material has environmental credentials (认证信息) as exciting and overlooked as wood. The energy required to produce a laminated wooden beam (层压木梁) is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing, wooden buildings contribute to negative emissions by storing the stuff. And for refitting older buildings to be more energy efficient, wood is a good insulator (绝缘体). A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium (铝) equivalent.
But such bigger stories are still uncommon. Governments can help push the industry to use more wood, particularly in the public sector — the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are presented in materials.
Construction codes could be regulated to make building with wood easier. Here the direction of travel is wrong. Britain, for instance, is banning the use of timber on the outside of tall buildings after 72 people died in a tower fire in London in 2017. That is a nonsense. Grenfell Tower was covered in aluminium and plastic, not wood. Modern cross-laminated timber (交叉层叠木板) panels perform better in fire tests than steel ones do.
Carpentry alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than is appreciated. The second little pig was not wrong, just before his time.

2 . Royal Dutch Shell is launching a $ 300 million and forestry program, at a time when an increasing number of oil companies are putting money in carbon offset (碳补偿)plans to meet climate goals. The company will spend the money over the next three years on projects to store carbon, including large forests in the Netherlands and Spain, and will start offering motorists the option of purchasing carbon offsets when they buy petrol at the pump.
The executives of the company explained that these carbon offset projects were a new business opportunity for Shell, as well as a way to meet its climate targets. “We believe that over time we will be building a business, because these carbon credits will become more valuable as carbon becomes more limited," they said. Shell recently decided to cut its net carbon footprint (碳排放)by 2-3 percent in five years, which includes emissions (排放)from the products it sells. The company plans to produce carbon credits from the forestry projects, then sell these credits on to customers buying its oil and gas products, or apply the credits to its own operations to lower its carbon footprint.
Plants absorb carbon dioxide as they grow and restoring forests and other natural areas is considered one of the simplest ways to store carbon. However, the voluntary market for carbon credits based on forestry projects has its critics, as projects in developing countries can be hard to monitor. Shell's move has also been criticized by some environmentalists. They worried that there was a risk of " greenwash when companies invested in forestry projects. "There is an entire debate about whether forestry projects truly reduce emissions or not," they said, pointing out that planting in one area could cause deforestation (滥伐森林)to another.
Shell said it would rely on the third party to ensure its forest program to meet the Voluntary Carbon Standard and strict biodiversity requirements. Mark Lewis, head of climate change investment research at BNP Paribas, said, " Planting trees to offset emissions, as far as it goes, is a step in the right direction."

3 . The United Nations Environment Program is calling for urgent action to reduce growing risks from chemicals. Better management of chemicals could save millions of lives and billions of dollars. As estimated, 143,000 chemicals are now produced. Yet the report says only a small number of these chemicals have been studied for their effects on human health and the environment. It says death and disability rates are high from the unsafe use of chemical products.
Sylvie Lemmet, director of the UNEP, says poor management of chemicals has a high economic cost. For example, she says the cost is higher than the amount of overseas development aid, or ODA, for health care in sub-Saharan Africa.
She says, “If you look at the estimated cost of poisoning from pesticide (杀虫剂) in sub-Saharan Africa, only the injury and the loss of working time is estimated to be 6.3 billion US dollars in 2009. This is higher than the total ODA that is going to the health part in the same area.”
The UNEP estimates that chemical sales worldwide will increase by around three percent a year until 2050. Chemical production is moving quickly from developed to developing countries. By 2020, chemical production is expected to increase by 40 percent in Africa and the Middle East and 33 percent in Latin America. One of its biggest concerns is pollution of rivers and lakes by pesticide and fertilizer. Other major concerns are heavy metal pollution from the production of cement (水泥) and textiles (纺织品), and dioxin pollution from mining.
The UN report urges the chemical industry and governments to work together to develop safety policies. It says preventing harm costs less than fixing it.

6 . Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet, or new plans to battle its effects. But the concept itself isn't new at all --- in fact, scientists have been exploring questions about climate change for almost 200 years.
The idea of “greenhouse gases” goes back to 1824, when Joseph Fourier wondered what was regulating the earth's temperature. Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat. As Fourier's ideas spread, it came to be called “the greenhouse effect”.
Scientists continued to study the greenhouse effect. Not until a Swedish chemist named Svante Arrhenius came along, did scientists understand how global warming actually works. After years of work, Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures.
Arrhenius found that CO2, and other gases trap radiation, which warms the atmosphere. Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect. But Arrhenius welcomed the warming effect on the planet. At a lecture later that year, Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.
While Arrhenius' findings won him the 1903 Nobel Prize in chemistry, scientists kept debating whether the greenhouse effect was increasing until 1950, when researchers finally began to find strong data supporting it. By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect – still, maybe Arrhenius should have been more careful of what he wished for.
