Moss Biofilters and Environmental Impact

The video discusses the impact of air pollution on health and climate, highlighting a Berlin-based company's innovative use of moss biofilters to clean and cool urban air. The founder's personal experience with poor air quality in Shanghai inspired the development of this technology. Moss, with its unique properties, acts like a city's lungs, absorbing pollutants and CO2. The biofilters not only purify air but also reduce temperatures, potentially mitigating climate change. The video envisions a future where buildings and highways are lined with moss, enhancing urban environments.

What is the estimated number of people killed by air pollution each year according to the World Health Organization?

• Its high leaf surface ratio

• Its ability to photosynthesize at night

How does moss act similarly to human lungs?

• By absorbing pollutants with a high surface area

• By regulating temperature

• By filtering water

• By producing oxygen

What is the significance of the black bits observed in the moss under a microscope?

• They are a sign of nutrient deficiency

• They represent new moss growth

• They are fine dust particles from polluted air

• They indicate the moss is unhealthy

What additional benefit do moss biofilters provide besides cleaning the air?

• They enhance plant growth

• They reduce noise pollution

• They cool the air

• They increase humidity

How are air pollution and climate change related?

• Air pollution reduces the greenhouse effect

• Air pollution has no impact on climate change

• Pollutants like black carbon accelerate global warming

• Air pollution cools the planet

What future vision does the company have for moss biofilters?

• To create moss-based energy sources

• To use moss in personal air purifiers

• To cover buildings and motorways with moss filters

• To replace all urban trees with moss

Why might it be beneficial to take inspiration from nature in addressing environmental issues?

• Nature has been regulating the environment longer than humans

• Nature is more cost-effective

• Nature is easier to control

• Nature is less complex
