    In the past, I heard a biology teacher say that if there is no carbon dioxide, then there is no way for oxygen molecules to exist, and then these living organisms cannot survive. We all know how important oxygen is to human beings. This is a matter of cause and effect, and only with the presence of carbon dioxide can humans continue to survive.

    Carbon dioxide is one of the main components of the atmosphere, and the oxygen component in carbon dioxide is exactly what people need, that is, with carbon dioxide the atmosphere can maintain balance.

    Because carbon dioxide can effectively protect the temperature of the earth and give human beings a suitable living space, when the concentration of carbon dioxide becomes high, global warming will lead to serious tilting of the world.

    Because carbon dioxide was the main component of the prehistoric atmosphere. Without carbon dioxide, the atmosphere would not have had enough energy to evolve, and perhaps there would not be the current levels of oxygen, and humans would not be able to appear on Earth.

    Summary. Dear dear, it's a pleasure to answer your <>

    First, human activities are one of the main causes of the increase in carbon dioxide concentrations in the atmosphere. Humans release large amounts of carbon dioxide into the atmosphere through activities such as burning fossil fuels, deforestation, and land-use change. These activities have led to an increase in carbon dioxide, which in turn has triggered global climate change and the greenhouse effect.

    Secondly, the increase in carbon dioxide has many effects on humans. High concentrations of carbon dioxide can cause the Earth's temperature to rise, triggering extreme weather events such as droughts, floods, and hurricanes. Climate change also affects crop growth, water resources** and ecosystem stability, negatively impacting human food security, water resources and health.

    In addition, the increase in carbon dioxide is also related to problems such as rising sea levels, melting of bent grove glaciers, and ocean acidification. These problems pose a threat to coastal areas, island States and marine ecosystems, affecting the living environment and way of life of humans. Carbon dioxide emissions from human activities are one of the main causes of climate change.

    Reducing carbon dioxide emissions is one of the important measures to cope with climate change<>

    According to some data, cars and heating account for only 54% of carbon dioxide emissions, and the remaining 46% comes from people's daily consumption. In fact, everything we do and the food we consume produces harmful carbon dioxide. Here's how much CO2 is emitted in everyday life:

    A large-displacement car travels 20,000 kilometers in the city every year, and it releases 2 tons of carbon dioxide. The amount of carbon dioxide released into the atmosphere by an engine is kilograms for every 1 liter of fuel burned. The human body releases about 1 kilogram of carbon dioxide per person per day through breathing.

    PlantsPlants absorb carbon dioxide during the day and release it at night. As a result, the net CO2 emissions of plants are zero. A medium-sized plant can absorb about 6 kg of carbon dioxide per year.

    The average computer indirectly emits kilograms of carbon dioxide in a year. Halogen bulbs indirectly emit an average of kilograms of CO2 per year. Heating, which uses kerosene as fuel, emits tons of carbon dioxide into the atmosphere in a year.

    CO2 emissions from natural gas are tonnes, while electric heating is only 600 kilograms. Washing machines emit an average of kilograms of indirect CO2 per year. Refrigerators emit an average of kilograms of indirect CO2 per year.

    EggsAlthough eggs are a natural food, in order for them to be on the table, they need to go through processes such as raising, packaging, and transportation. Chicken farms also need maintenance. Chicken produces 4 times more greenhouse gases than beef.

    Dairy productsThe production of dairy products is pasteurized, which requires the milk to be heated to 72 degrees Celsius in 15 seconds. If you choose high-temperature sterilization, you need to heat it to 140 degrees Celsius, which takes longer. Imported fruit is transported by plane with a flight distance of 10,000 kilometers and tons of carbon dioxide emitted.

    Although the process of producing grains, vegetables and fruits emits less carbon dioxide than the production of meat, frozen foods need to be cleaned, heated, packaged and frozen, which all contribute to carbon dioxide emissions. Fruit juice is rich in vitamins, but it is also an "abyss" of energy consumption, as it consumes energy from production to supermarket shelves. Controlling energy consumption in daily life can effectively avoid carbon dioxide emissions and prevent tons of harmful gases from being released into the atmosphere.

    If we keep the temperature of the air conditioner between 24 and 26 degrees Celsius, not only can we save 5 to 10 percent on our electricity bills, but we can also reduce the amount of carbon dioxide released per household by 300 kilograms per year. The use of light bulbs with low power consumption can reduce harmful gas emissions by 400 kg per household.

    If the earth loses carbon dioxide, green plants will not survive, and people will suffocate due to lack of oxygen without plants. Because green plants produce oxygen by absorbing carbon dioxide, humans exhale carbon dioxide by inhaling oxygen, which means that without carbon dioxide, all animals and plants on the earth will disappear.

    Carbon dioxide. It is an indispensable substance for human survival The main ways to produce carbon dioxide in nature are the combustion of fossil fuels and the respiration of humans and animals; Deplete.

    Second, the pathway of carbon oxide is mainly the photosynthetic spring banquet chain of plants.

    The increase in the amount of carbon dioxide in the air has exacerbated the greenhouse effect.

    In order to maintain the balance of carbon dioxide in the atmosphere, the measures that can be taken are to reduce the use of fossil fuels, develop new energy sources to replace fossil fuels, and vigorously plant trees. photosynthesis in plants; Conservatory; Reduce the use of fossil fuels

    If the amount of carbon dioxide in the air is too low, the amount of oxygen emitted by the plants will be greatly reduced.

    We know that one of the raw materials for light and action in plants is carbon dioxide. Plants cannot perform light and function without carbon dioxide.

    Therefore, if the amount of carbon dioxide in the air is too low, the oxygen level in the air will be too low, and animals and humans (all living beings that need oxygen) will die without a lot of oxygen. This has led to a series of ecological problems.

    Such a vicious circle has unimaginable consequences.

    Many people believe that carbon dioxide is responsible for the greenhouse effect, so the less carbon dioxide in the air, the better.

    First of all, everyone knows about the greenhouse effect, ** overwhelming propaganda--- polar icebergs melting, sea levels rising, many animals and plants unable to adapt to the environment and disappearing...

    It is true that higher carbon dioxide concentrations can seriously affect the respiration of living organisms. The reason is that the concentration of carbonic acid in the blood increases, and the acidity increases, causing acidosis in the organism. When the volume fraction of carbon dioxide in the air is 1%, people will feel stuffy, dizzy, and palpitated; When it reaches 4%-5%, people will feel dizzy; When it reaches more than 6%, it will cause confusion and gradual cessation of breathing, resulting in death.

    Because the density of carbon dioxide is greater than that of the atmosphere, there are always cases where people fall into dry wells and suffocate to death due to carbon dioxide.

    Therefore, many people think that more carbon dioxide is not good, so is it better to have less carbon dioxide in the air?

    Actually, it is not, as we all know, carbon dioxide is a greenhouse gas, and if there is very little, the temperature of the earth will inevitably drop, almost catastrophic. And photosynthesis requires carbon dioxide, and without carbon dioxide, plants cannot photosynthesize and cannot produce oxygen! This will threaten the entire ecological balance!

    If there were no greenhouse gases such as carbon dioxide and methane in the atmosphere, the temperature difference between day and night on Earth would be staggering. During the day, the sunlight shines in, but at night, the temperature is emitted into the universe due to the absence of greenhouse gases such as carbon dioxide, and the night on Earth will be unusually cold.

    Carbon dioxide also plays an important role in maintaining the pH balance of the ecosystem! If the carbon dioxide content in the atmosphere plummets to zero, then the carbon dioxide in the soil and water will be lost to the air, and the pH of the water and soil will be out of balance, more alkaline, which will cause a large number of microorganisms, animals and plants to die!

    So, do you still hate carbon dioxide gas?

    1. Monstera.

    Monstera absorbs carbon dioxide at night, improves air quality, increases oxygen content, and also has a significant effect on removing formaldehyde from the air. The monstera is generally larger, elegant in shape, and the leaves are relatively sparse and beautiful, which is ornamental. When the fruit is ripe, it can be cooked, and the aroma is like pineapple or banana.

    2. Rubber tree.

    The rubber tree is an all-rounder for the elimination of harmful substances. For example, harmful gases such as carbon monoxide, carbon dioxide, and hydrogen fluoride in the air. Rubber trees can also eliminate inhalable particulate pollution, which can effectively trap indoor dust.

    3. Palm bamboo. Palm bamboo can eliminate heavy metal pollution and carbon dioxide, and the function of palm bamboo is similar to that of monstera. Palm bamboo, which is also a large-leaved ornamental plant, can absorb more than 80% of a variety of harmful gases and purify the air.

    At the same time, palm bamboo can also eliminate heavy metal pollution and has a certain resistance to sulfur dioxide pollution. They digest carbon dioxide and make oxygen.

    Humans have so far emitted trillions of tons of carbon into the atmosphere. If the increase in global average temperature is to be kept to 2 below pre-industrial levels, carbon emissions must be limited to less than 1 trillion tonnes of carbon from now on; If warming is to be contained, the global carbon budget will be even tighter.

    However, John Shepherd admits that the current model research is still limited and uncertain, and the full impact of SRM, such as the impact on the ozone layer, acid rain, global precipitation, etc., is still poorly understood. Moreover, the influence of physics is only part of the equation, and it proves to be more difficult to prove on a socio-political level than natural science research.

    In the past, most SRM research and discussion has been conducted in developed countries, and only a small number of scholars in China have paid sporadic attention to international developments. "In 2015, China launched the first geoengineering '973' project. Chen Ying, a researcher at the Institute of Urban Development and Environment of the Chinese Academy of Social Sciences, said.

    This worries scientists working on climate change. "Reducing emissions to mitigate global warming is critical, but may not be enough to reduce the climate risks posed by existing carbon emissions. Adaptation to climate change is equally important, but it does not solve all problems.
