Ô nhiễm không khí: Dân lo, giới chức nói vẫn ổn

lại phải đợi đến doanh nghiệp khởi nghiệp bắt tay vào thôi, "trồng" "cây nhân tạo" có khả năng lọc không khí bằng 275 cây xanh, quanh thành phố london...

...This compact bench (ghế dài) and pollution filter (lọc ô nhiễm) has the air cleaning capabilities of 275 trees, all while taking up just 1% of the space real trees would need to do the same job.

The German startup has continued to place CityTrees in cities around the world, and now they’ve landed in London. Thanks to The Crown Estate, the first CityTree has been set up on Glasshouse Street, close to the buzz of Picadilly Circus. The installation couldn’t come soon enough, with London’s air pollution consistently going over legal annual levels within the first few weeks of each year.

So how does CityTree work? More than just a bench, its combination of mosses (rêu) and plants organically removes dust (bụi), nitrogen dioxide, and ozone gases from the air. It also has a built-in monitoring system (hệ thống theo dõi) that checks pollution levels (mức độ ô nhiễm), air temperature (nhiệt độ không khí), and water quality (chất lượng nước), among other things, and is fitted with solar panels (tấm điện mặt trời) for complete self-sufficiency (tự cung tự cấp, tự túc, độc lập).
