Protecting the planet's environment is not a choice, but a necessity, as it is the only home we have left. The global environment is currently suffering from heat waves, heavy rainfall, and cold winters, increasingly powerful typhoons and hurricanes, changes in jet streams, inundation of low-lying areas due to melting Antarctic and Arctic ice and rising seawater, desertification and frequent large wildfires, and changes in ecosystems
due to warming. In order to make the earth safer and more livable for future generations, people's perceptions and behaviors toward the global environment need to change.
In general, scientists believe that the Earth is 150 million kilometers from the Sun, and that the Earth revolves around the Sun at a speed of 29.8 kilometers per second with a rotation rate of 23 hours and 56 minutes per day and an inclination of 23.5 degrees. The Earth's circumference is about 40,000 kilometers, and there are currently about 8 million species of life on Earth. Due to the distance and tilt from the sun, which
is the source of energy, seasonal changes occur, photosynthesis of plants, and the atmosphere and greenhouse effect, the average temperature of the earth is about 290K (16. 85 degrees Celsius), and the atmosphere keeps the temperature difference between night and day from being too large, making it a good environment for people and other living things to live in. The atmosphere, which is an air layer that protects life, is composed of 78% nitrogen, 21% oxygen, 1% water, 0.93% argon, 0.03% carbon dioxide, neon,
carbon monoxide, methane, hydrogen molecules, ozone, helium, krypton, etc.
The earth currently has five continents, Asia, Europe, America, Africa, and Oceania, and seven oceans (or five seas), consisting of the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian Ocean, Southern Ocean (Antarctic Ocean), and Arctic Ocean. About three-quarters of the earth's surface is ocean, and the water on the earth consists of 97% seawater, 2% glaciers, 1% groundwater, lakes, and rivers, and 2/3 of
the surface water is in the ocean, so the importance of water and seawater seems to be greater than expected. In addition, in 1000 grams of seawater, 965 grams of water and 35 grams of salts are dissolved, and salts include 27.2 grams of sodium chloride, 3.8 grams of magnesium chloride, 1.7 grams of magnesium sulfate, 1.3 grams of calcium sulfate, 0.9 grams of potassium sulfate, and 0.1 grams of other substances.
The average human body is composed of 66% water, 16% protein, 13% fat, 4% minerals, 0.6% carbohydrates, and 0.4% other, and water tends to decrease gradually from 80% in infancy, 70% in the 20s and 30s, 60% in the 40s and 50s, and 50% in the 60s and 70s. Beef and pork also contain 60-70% moisture, fruits contain around 85% moisture, and vegetables are higher than this, and if the moisture content is more than 16%, microorganisms
can live. Moisture is considered an essential element of life, and in particular, water, air, and proper temperature are essential conditions for survival, and climate is considered the most important factor for life on Earth, including people, and various cycles.
In the case of the Earth, convection occurs due to solar energy, rotation, tilt, temperature difference and moisture content in each region, and the northeast trade winds between the equator and 30 degrees of latitude, the southwest winds between 30 and 60 degrees of latitude, and the northeast winds at 60 degrees of latitude and the polar regions. In addition, convection phenomena occur between deep and surface currents in
the ocean due to temperature differences and salinity differences, and large and small circulation occurs by region.
Therefore, the earth and human body are also complex and mysterious creatures that are difficult to explain with current science, and to keep them healthy, not only the components are important, but the earth's climate and temperature play an important role, and it is thought that maintaining the right temperature is essential for a virtuous cycle.
It is said that if the body temperature rises by 2 degrees, a person will get a fever, and if it exceeds 40 degrees, the entire body can be ruined as one by one body organs have problems, and in the case of the earth, if the temperature rises by 2 degrees, more than 99% of coral reefs disappear, and about once every 10 years, the Arctic ice completely melts, causing the level of sea water to rise, and various circulation processes
to speed up, causing extreme weather events to become more frequent and heavy rainfall depending on the region, Drought, desertification, etc. and changes in the environment and food chain may lead to the disappearance of many species, and food shortages due to a decrease in grain production areas, and the risk of conflicts and wars to secure resources in each country may cause a major disaster for humanity. Therefore, the Intergovernmental Panel on Climate Change (IPCC) explains why it is imperative to limit
the increase in global temperature to no more than 1.5 degrees Celsius above pre-industrial global temperatures by 2100.
Global warming is caused by
The vast majority of scientists agree that a layer of carbon dioxide in the atmosphere that surrounds the Earth, acting as a greenhouse, is the primary cause. The Earth's temperature, which is maintained by a moderate layer of greenhouse gases in the atmosphere, has gradually increased in recent centuries due to a number of causes, including carbon dioxide emissions from many living organisms that exceed the Earth's ability
to self-correct; increased carbon dioxide and active energy from the use of oil, coal, and uranium buried in the ground due to rapidly increasing energy demand; the release of methane gas trapped in glaciers; and the reduction of snow and ice that reflect 80 to 90 percent of the sun's light. According to scientists, the increase in carbon dioxide, methane, nitrous oxide, etc., which are the main culprits in heating the earth, gradually increases the global temperature due to the greenhouse effect, which creates
an air layer of carbon dioxide and other substances that traps solar radiation arriving at the earth, and the thicker the carbon dioxide layer, the more intense the heat wave, heavy rain, heavy snowfall, and winter cold snaps may become due to radiation and the heat island effect.
In addition, glaciers in the Arctic and Antarctic have the function of reflecting sunlight in addition to their own thermal cooling function to regulate the temperature of the entire planet, but if these polar glaciers melt and become black seas, they can absorb sunlight and accelerate warming. As warming continues to intensify due to various factors, if the critical point of the earth's virtuous cycle environment is exceeded,
the resilience of the entire global climate system may rapidly deteriorate, and it may no longer be controlled or controlled by humans, and human survival may be threatened. Therefore, the pledge of world leaders in the Paris Climate Agreement to limit global warming to between 1.5 and 2 degrees Celsius is an imperative.
If the planet continues to warm in an upward trend
First, climate change tends to intensify as various cycles accelerate.
Currently, global temperatures are close to 1.5 degrees Celsius above pre-industrial levels, and this is causing ocean heat waves that increase the temperature of the oceans over thousands of square kilometers over a few days or days, with up to a 20 percent increase for a 1-degree increase in global temperature, a 44 percent increase for a 1.5-degree increase, and an 80 percent increase for a 3. As the number of ocean heat
waves doubled between 1982 and 2016, corals are dying and their symbiotic relationship with algae is deteriorating, and global warming is raising ocean temperatures, leading to more intense ocean heat waves, according to a paper published in Nature by a team led by Professor Thomas Froescher of the University of Bern, Switzerland. Over the past 100 years, ocean temperatures have risen by about 1 degree Celsius, and each degree Celsius of warmer water increases water vapor in the atmosphere by about 7 percent,
making typhoons more powerful and destructive. In September 2018, Typhoon Mangkhut had wind speeds of up to 285 kilometers per hour (km/h), Hurricane Florence dropped nearly a meter of rain in September, and Typhoon "Witu" reached wind speeds of 58 meters per second, toppling cars, toppling street lamp posts like dominoes, shattering windows, and ripping roofs off buildings. Meteorologists say that if warming continues, typhoons and hurricanes are expected to become more powerful, with many super typhoons
reaching speeds of more than 320 kilometers per hour. Increased trade winds and changes in ocean temperatures are also expected to trigger El Niño events (warmer waters) and La Niña events (cooler waters) in the eastern Pacific below the equator, which could lead to more extreme weather, including heat waves, typhoons, heavy rains, severe cold, heavy snow, strong winds and gusts, droughts, and large wildfires.
Even in the case of summer heat waves, water generally heats up slowly and cools down slowly, so if the water retains a lot of heat, the heat wave will last longer. According to data from the National Academy of Fisheries Science, the surface water temperature of the seas around the Korean Peninsula increased by 1.1 degrees between 1968 and 2015, with the East Sea increasing by 1.39 degrees (15.93 degrees to 16.74 degrees),
the South Sea increasing by 0.91 degrees (17.95 degrees to 18.58 degrees), and the West Sea increasing by 1. Accordingly, changes in fish species are occurring depending on the water temperature, such as pollock and herring gradually disappearing in the East Sea, squid and anchovies being caught in the West Sea, and subtropical fish that have not been seen before being caught. In addition, the average summer water temperature is 24 to 25 degrees, but it has increased by an average of 0.17 degrees per year since
1997, and it has increased by 0.34 degrees per year since 2010, and the temperature of the West Sea in particular has increased by 0.54 degrees per year (average water temperature in July since 2010). And when seawater retains a lot of heat, it creates a vicious circle, fueling heat waves. Extreme cold in winter is also known to be caused by glacier melting, changes in atmospheric pressure, and changes in jet streams.
Second, food supply could suffer.
In the last 30 years, the average number of heat wave days on the Korean Peninsula has been about 10 days, but by 2050, the Korean Peninsula could become a subtropical climate with an average annual temperature of more than 17 degrees Celsius, with hot summers lasting from May to September, and heat wave days of more than 33 degrees Celsius could increase to 50 days. In addition, tropical nights with nights over 25 degrees are
said to be longer than 30 days, making it difficult to grow apples and peaches, and citrus and sweet persimmons may increase. In addition, fish species that live in cold waters, such as pollock saury, will find it difficult to survive. As the earth's temperature continues to rise, it could affect the growth of major crops and affect food supply. Species that can't adapt to the temperature could become extinct.
According to the UN report, Manila and Tokyo in the Philippines have experienced 4.25 meters of land subsidence in 100 years, Bangkok in Thailand has sunk 1 meter in 10 years, and many other cities are at risk from rising sea levels, including Ho Chi Minh City, Vietnam; New Orleans, USA; Shanghai, China; Venice, Italy; and Dhaka, Bangladesh. The 2017 United Nations Climate Change Conference in Bonn, Germany, predicted that climate
change is progressing faster than previously thought and that by 2100, temperatures will be more than 3 degrees Celsius above pre-industrial levels and sea levels will be 6.4 meters higher. Rising sea levels are thought to have a significant impact on many cities and agricultural lands in low-lying areas.
In addition, as the overall temperature of the earth increases due to radiation, the evaporation of moisture speeds up, causing arid areas such as deserts to increase in many parts of the world, and in some areas, making it more prone to extreme weather events such as heavy rainfall and wind gusts. 05% volume expansion per degree) affects the water pressure, which is thought to affect the earthquake zone where the ground is
weak, and the increase in temperature of the sea makes typhoons and cyclone hurricanes more powerful due to the increase in water vapor, and the change in ocean temperature is thought to have a major impact on climate change by affecting high and low pressure zones in conjunction with radiation heat and the earth's rotation, causing heat waves and extreme cold. Therefore, as the global temperature rises, a vicious circle occurs, and at some point it may become uncontrollable, adversely affecting the production
and supply of major agricultural crops along with the reduction of agricultural production areas, and gradually changing the environment that is difficult for living beings such as humans to live in.
Third, many species could become endangered and epidemics could become widespread.
The current trend is measured to be about 0.2 degrees Celsius per decade, and a collaborative team of researchers from the United States, United Kingdom, Germany, Australia, Sweden, Dunmark, Belgium, and the Netherlands has concluded that global warming is caused by more than 15 interacting and intertwined causes (a decrease in forests can lead to a 0.25-degree increase, melting permafrost can lead to a 0. In the worst case
scenario, the temperature may rise by more than 5 degrees by 2100, and even now, due to global warming and environmental change, coral reefs in the ocean are dying, many creatures such as polar bears, koalas, walruses, African penguins, and bearded whales are already endangered, and many species are thought to be in danger due to environmental changes and destruction of habitats, such as the destruction of rainforests due to industrialization. Rising average temperatures also make the environment more conducive
to infectious diseases. According to a study by the Korea Institute of Health and Social Research, a one-degree increase in average temperature is associated with a 1.81% increase in bacterial dysentery, 3.29% increase in enteritis vibrio, 3.40% increase in malaria, 4.07% increase in leptospira, and 5.98% increase in tsutsugamushi disease. As such, it is thought that rising temperatures and extreme weather will create an environment in which stronger and more mutated viruses such as pandemic influenza, MERS-CoV-2,
SARS, and Avola can be created, and the risk of mutant infectious diseases will increase, and if the ability of countries to cope with them decreases, the likelihood of their spread will increase due to globalization, increased trade volume, development of transportation, and an increase in travelers.
Fourth, individuals and societies that are becoming increasingly selfish should be transformed into more selfless and virtuous communities,
because selfishness can lead to unlimited competition, which can lead to man-made environmental disasters due to indiscriminate non-environmental scientific development. The Kyoto Protocol, the first global agreement to respond to climate change, first came into effect in February 2005, but it will expire in 2020, so the Paris Agreement to replace it was adopted unanimously by 195 countries in Paris, France, in December 2015
to phase out greenhouse gas emissions to keep the temperature from rising more than 2 degrees above pre-industrial levels by 2100, but since then, depending on the interests of each country, it has been withdrawn based on the opinions of a small number of scientists. The United States withdrew from the Kyoto Protocol in March 2001 and the Paris Agreement in 2017, citing national interests, and Russia, Japan, and Canada have also withdrawn from the Kyoto Protocol. It is believed that this may be a great sin of
ignoring posterity and future humanity as a result of selfish behavior that values the interests of one's own country more than the interests of the entire planet. Therefore, although there are many factors that make it difficult to integrate, such as customs, ideologies, religions, regions, politics, and history, it is believed that we should reduce selfishness and participate in protecting the global environment for the sake of a virtuous cycle and the future and common interests of the entire planet before
it is too late. Therefore, a global economic virtuous circle community should be created to reduce the selfish behavior and conflicts of each country.
It is said that it takes about 8 minutes at the speed of light to travel from the Earth to the sun, and 1 year at the speed of light to travel to the end of the solar system. It is said that there are more than 200 billion stars in the galaxy, which are self-luminous stars like the sun, and that it takes 100,000 years at the speed of light to go from one end of the galaxy to the other, and that there are more than 1 trillion
such galaxies that can be observed by converting the universe photographed by the Hubble telescope into three dimensions, so it is difficult to imagine the vastness of the universe, and that millions of different types of living things live in the earth where people live, so I think that what we know is weak and the scientific knowledge that is already known is only a small part. However, it is difficult to protect the earth's environment without effort, and I think that making a virtuous cycle of the earth's
environment through unremitting efforts will secure the sustainability of human survival and be in line with divine providence.
In addition, I hope that in the future, if new science and technology develops by leaps and bounds, we will be able to control the global environment, find a second or third Earth with a similar environment to Earth where people can live in space, develop technology to create a similar environment on a star with the right temperature, or make leaps and bounds in transportation technology.
