The home humidity (湿度) is a measurement of the amount of vaporized (汽化了的) water in the air of the home. Humidity levels are naturally higher in warmer climates and lower in cooler climates. 1.Older and less energy efficient homes tend to have lower indoor humidity levels, while modern homes with higher energy efficiency tend to have higher humidity levels.
Both high and low home humidity levels can cause problems. Humidity levels that are too high can affect paint and cause mold (霉菌) . Humidity levels that are too low can cause cracks in your drywall and affect furniture. 2.
You may wonder what exact level of humidity you should have. Generally, people are most comfortable when home humidity is between 20 and 60 percent. 3. It can balance your need for comfort with the conditions that are less likely to damage your house.
4. It doesn't require expensive equipment. Just drop three ice cubes into a glass, add water, shake it and wait for three minutes ; if moisture(水汽) does not form on the outside of the glass, you may need to increase humidity. On the other hand, if you notice frequent fogging of your windows, you may have too much humidity in your home.
Daily activities like cooking can add water to the air in your home. If the home humidity level is top high, you can start cooking with pans covered. 5. If these basic changes don't help correct the problem, use a dehumidifier.
A. This is the ideal humidity level.
B. You must add water on a regular basis.
C. High humidity levels can damage furniture.
D. So do avoid too high and also too low humidity levels.
E. Taking shorter showers may also control the humidity.
F. Home humidity levels can be measured in simple ways.
G. The type of home can also affect the humidity measurements.
A device called a TreeTalker is providing information about trees to people who oversee forests and woodlands. The device aims to measure the growth and general health of trees.
Scientists say forests are important because they absorb, or take in, carbon dioxide, one of the gases released by burning oil and other fossil fuels. It is a heat-trapping gas and has been linked to a general warming in the Earth's atmosphere.
The world is at a historic period for climate change because the scientific world is on guard. Many scientists say “Be careful, the ecosystem of the forests is not able anymore, as it was before, to absorb all this carbon dioxide.” Rising temperatures are placing forests under increased stress. Harmful insects and diseases are becoming more of a threat to trees. This is bad for the environment.
The TreeTalker devices serve as an early warning system for people overseeing forests. TreeTalker turns eco-physiological signals, such as growth, absorption of carbon dioxide, liquid flow from roots to leaves, into scientific information. This can help show if a tree is under attack from insects or other organisms. The TreeTalker sends its information to forest managers.
The TreeTalker device transmits data via radio and it can transmit data actually a very long distance, up to one kilometer. The information lets forestry officials take action immediately to control threats. The TreeTalker is able to measure the width of the bottom of a tree. Timber industry workers can use this information to know how much wood they are growing compared to how much they are harvesting. Another goal is to give scientists the information they need to understand how climate affects forests and the part trees play in a healthy environment.
About 300 TreeTalker devices are being tested in Italy and other countries, such as China and Russia. Another 1,700 devices are expected to be tested worldwide this year.

An extraordinary new restaurant in Semarang, Indonesia is on a mission (使命) to support locals trapped in poverty, many of whom are earning less than $25 a month, by providing them with an alternative way to pay for their food.
The Methane Gas Canteen, run by husband and wife team Sarimin and Suyatmi, is located in an unexpected place for an eatery — Jatibarang Landfill. The landfill is a mountain of purifying waste, where poor locals spend their days collecting plastic and glass to sell. Meanwhile, the couple, who spent 40 years collecting waste before opening the restaurant, is busy cooking.
What makes the restaurant unusual, aside from its location, is that no cash is required to pay for meals. Poor people have the option to pay for their food with recyclable waste instead of cash. Sarimin weighs the plastic customers bring in, calculates its worth, and then deduct that value from the cost of the meal, giving any extra value back to the customer. The scheme is part of the community’s solution to reduce waste in the landfill and recycle non-degradable plastics.
“I think we recycle 1 ton of plastic waste a day, which is a lot. This way, the plastic waste doesn’t pile up, drift down the river and cause flooding,” said Sarimin in an interview with Channel News Asia. “It benefits everyone.”
The restaurant seats about 30 people and serves meals that cost between $0.40 and $0.80 each. Since opening the canteen Sarimin and Suyatmi have seen their daily income more than double to $15 a day.
“I’m happy to see our customers enjoying their meals,” Sarimin told NHK World. “The poor must also have the right to enjoy healthy eating. I want to give them that chance as much as possible.”
