3 . Conifers (针叶树) are generally better than broad-leaved trees at purifying air from pollutants. But deciduous (落叶的) trees may be better at taking in particle-bound pollution. A new study led by the University of Gothenburg shows that the best trees for air purification depend on the type of pollutants involved.
Trees and other greener in cities provide many benefits that are important for the well-being of residents. Leaves and needled on trees filter air pollutants and reduce exposure to poisonous substance in the air. But which trees purify the air most effectively? Researchers from the University of Gothenburg have collected leaves and needle from eleven different trees growing in the same place in the Gothenburg Botanical Garden (GBG) to analyse which cub-stances they have absorbed.
“This tree collection provided a unique opportunity to test many different species of trees with similar environmental conditions and exposure to air pollutants,” said Jenny Klingberg, a researcher of the GBG
A total of 32 different pollutants were analysed, some of which are bound to articles of various sizes. Others are gaseous. This project has focused on paths (多环芳烃). In cities, traffic is the biggest source of these pollutants, which are released due to incomplete burning in engines.
“Our analysis show that different species of trees have different abilities to absorb air pollutants. Conifers generally absorb morn gaseous paths than broad-leaved trees. Another advantage of conifers is that they also act as air purifies in winter, when air pollution is usually at its highest,” said Jenny Klingberg.
“This study contributes to improving our understanding of the ability of trees to clean the air and which species are best at absorbing air pollutants,” said Jenny Klingberg. This known-edge is important for urban planning when designing sustainable cities. While trees and green-era can contribute to better air quality in cities, at the end of the day, the most important measure is to reduce emissions.

4 . Scientists say the Earth’s temperature has risen by about 1.1 degrees Celsius since the modern industrial period began. And they warn that the effects of rising temperatures will get worse with every increase of one tenth of a degree.
It is important to not burn more fossil fuels such as coal, oil and natural gas. Such fuels release carbon dioxide. Many scientists blame rising temperatures on carbon dioxide trapping heat in the Earth’s atmosphere.
The world depends on fossil fuels for much of its electricity, heating and transportation. Fossil fuels are also important for agriculture and industry. But cleaner, renewable energy sources—such as solar and wind energy—will replace much of that demand.
Observers say the cost of renewable energy is decreasing. Also, more renewable energy is being produced in sustainable ways. However, the total amount of energy produced has also gone up. Many places are using renewable energy, but emissions are continuing to rise.
That is why experts are studying technologies that might be used in some industries. Some have suggested using “green fuels,” such as ones made out of plant materials or natural waste, known asbiofuels (生物燃料).
Two newer technologies being explored include carbon capture, which takes carbon dioxide out of the air, and green hydrogen, which uses renewable energy to make hydrogen. But, these technologies are costly and untested completely.
Experts said there are two areas in which action could slow the warming of the atmosphere: stopping cutting down forests and reducing the eating of animals. Forests naturally take in carbon dioxide from the atmosphere. When forests are cut for agriculture, especially for animals that need large amounts of land, more greenhouse gases are drained into the air. In most higher income countries, most people eat far more meat than they need to.
