Cause and effect and measures of global warming, No 1 (1-4)
Cause and effect and measures of global warming, No 1 (1-4)
It may be a bit difficult story, and it may not be a very interesting topic
It is a very important story, so I will cover it.
Because the story is long, I will write it in two times.
1: desertification, 2: air pollution.
3: Carbon dioxide (greenhouse gas)
4: Ozone depletion (Fluorocarbon problem),
5: Extreme weather (large scale natural disaster)
6: deforestation (deforestation of the world) world,
7: red tide (sea water pollution) death of edible fish
8: Acid rain (decrease in lake, sea creatures, death)
1: Desertification, what kind of influence make it desertified?
Desertification means that healthy soil in which plants are
growing does not rain, withers out,
growing does not rain, withers out,
Finally it means the soil that it dries and plants no longer grow.
In addition, soil erosion and salt accumulation are also causes of
desertification.
desertification.
In the Sahara desert is proceeding with the momentum of 1.5
million hectares every year,
million hectares every year,
If you proceed as it is, the continent of Africa will become a desert
continent.
continent.
In China, desertification extends to Beijing.
Desert sand is blown by the wind and let it sand.
Desertification is progressing not only in these areas but also
in other areas.
in other areas.
This sand storm, as a yellow sand in Japan, in the neighboring
country Korea and beyond the sea,
country Korea and beyond the sea,
Fly away. The yellow sand contains a lot of pollutants such as PM25.
2: Why does air pollution and air pollution occur?
What is the influence of air pollution?
Air pollution is caused by pollutants contained
in automobiles and factory smoke
in automobiles and factory smoke
It means that the air is dirty.
This contaminant is nitrogen oxides (NOx), particulate
suspended matter (SPM), carbon dioxide (CO2).
suspended matter (SPM), carbon dioxide (CO2).
These substances start global warming, causing acid rain,
photochemical smog, etc.
photochemical smog, etc.
In Japan, the country's policy on air pollution has been
successful in recent years,
successful in recent years,
The color of the sky in the metropolitan area is better than before.
As an air pollution countermeasure from October 2003,
the diesel vehicle to the metropolitan area
the diesel vehicle to the metropolitan area
Regulation was done.
Basically it prohibits diesel vehicles from entering
the metropolitan area.
the metropolitan area.
Cars operating diesel vehicles have diesel particulate
collection filters (DPF)
collection filters (DPF)
By attaching, it is possible to deviate from
the subject of operation regulation.
the subject of operation regulation.
As a result, photochemical smog has been decreasing,
it has a proven track record.
it has a proven track record.
3: What is global warming caused by carbon dioxide,
methane gas, carbon dioxide?
Carbon dioxide is one of the greenhouse gases that
affect global warming.
affect global warming.
It is used as fuel. Combustion of petroleum · gasoline, power station,
There are many emissions from ironworks and other places.
Also, the permafrost of the Arctic Circle is warming, melts out,
the influence of methane gas generated
It is considered to be big. Methane gas has a greenhouse effect
that is 30 times higher than CO2.
4: What is the impact of the Earth due to destruction of the ozone layer and destruction of the ozone layer? What is the impact on humans?
The ozone layer is located 20 to 30 km above the ground.
It is a thin layer that protects everything on the ground from
ultraviolet rays.
ultraviolet rays.
We are going to destroy it. That is "ozone depletion".
Causes of ozone depletion by Freon gas: use of
alternative CFCs, recovery of CFCs
alternative CFCs, recovery of CFCs
Cause and effect of global warming and countermeasures, No 2 (5-8)
Also please look forward to the next story.
