What does "breathe" mean? Can roads really breathe?
Respiration refers to the exchange of gases between an organism and the outside world. Humans and higher animals breathe with their lungs, lower animals breathe through their skin, and plants exchange gases through surface tissues. The road "breathes" is written in an anthropomorphic way.
What are the main factors causing air pollution?
We all know that automobile exhaust is the main factor causing air pollution. The nitrogen oxides in the "Air Quality Daily" published every day by newspapers and TV refer to automobile exhaust.
What does the road "breathe" for?
Highway "breathing" is a method specially invented by scientists to remove air pollution.
How do roads “breathe”?
First, vents are arranged along the road, and then blowers are used to blow the exhaust fumes from the cars into the soil. Part of the nitrogen oxides is adsorbed on the surface of the soil, and the other part of the nitrogen oxides is dissolved in the water, absorbed by microorganisms in the soil, and turned into fertilizer.
Scientists have invented this good way to kill two birds with one stone. If you have any other good ways to clean the air and protect the environment, tell us. We will share them and then write them down in the book.
1. What things have we done to protect the environment?
2. Group cooperation and communication, what else can we do for environmental protection?
