1,000 people in Switzerland will “plant” two new cotton white underwear in farmland and vegetable garden in the past few days.
According to reports, the reason why the Swiss “plant underwear” across the country is to monitor the health of the country’s soil. The person in charge of the project said that this kind of soil research has also been done in Canada, but the scale is not so large. Now the Swiss participating in the experiment are voluntarily signing up. They use the decay of underwear and other natural textiles to monitor the soil, which is scientific and reliable. Sex. One month after “planting” the underwear, the scientists will assist the volunteers to dig out a pair of underwear for photo analysis and sampling; one month later, they will dig out another pair of underwear and perform the same operation. This observation of the decomposition process of natural fibers is relatively intuitive: the more holes in the underwear, the healthier the soil.
In addition, the researchers will examine the microbial DNA in the soil to find out which microbes are eroding the underwear. They said, “This is a very serious scientific experiment.”
A recent research report from the University of Houston in the United States shows that living next to a toxic garbage dump will reduce your life. The British “Guardian” reported on the 13th that the US Environmental Protection Agency confirmed that the average life expectancy of residents near the toxic garbage dump would be shortened by 0.25 years, while for people with economic difficulties, the life span may be reduced by one year.
According to the report, there are currently more than 1,300 toxic dumps in the United States recognized by the US Environmental Protection Agency, and these dumps can cause great harm to human health and the environment. As early as 1980, when a landfill of more than 22,000 tons of toxic industrial waste was landfilled in New York State, it caused various problems such as disease, miscarriage, neonatal deformity and even death of residents in the local area.
The researchers also reminded that in the event of a natural disaster, the toxic substances in the dump may further spread, causing greater harm, so the infrastructure of the dump must be more robust.
A recent study shows that noise pollution can have long-term negative effects on plants. The British “Guardian” reported on the 14th that in order to investigate the impact of noise on the ecosystem, researchers came to the Rattlesnake Canyon Ecological Management Area in New Mexico in 2007 to conduct investigations. The area is dominated by woodland plants, and the high-density natural gas wells inside will emit 100 decibels of noise for a long time, and this noise is the same as when a train passes through a station.
According to the report, after 12 years of investigation and analysis, researchers found that the density of saplings in a noisy environment is lower, and that trees aged 2-12 years grow more slowly. Birds will not eat tree seeds in noisy environments, because they will remember areas that make them uncomfortable.
Researcher Temont said, “We dare not say how serious the impact of noise pollution is, especially at the ecosystem level. But if noise continues to disrupt plant growth, it is likely to have an impact on the entire habitat.”
