Greenhouse gases

Because the life on the earth depends on the presence of atmospheric greenhouse gases, the surface of our planet is isolated from the coldness of the universe; without them, the average climate of the earth decreases by about 33 ° C I will do.

The atmospheric energy to the sun is mostly transparent, most of it can reach in the form of light. On the earth's surface, this energy is partly reflected back to the universe, partially absorbed and re-radiated as heat. Greenhouse gases in the atmosphere may absorb most of the heat that flows out and reemit them.

Atmospheric concentrations of several greenhouse gases, synthesis gas such as carbon dioxide (methane), methane (CH), nitrous oxide (N2 O), ozone (O), chlorofluorocarbon (CFC) and hydrofluorocarbon, The activities are directly affected. Compound (HFCS). Water vapor is also a major greenhouse gas, but concentrations in the atmosphere are not directly affected by human activity.

Since the industrial revolution around 1750, human activities have added a large amount of greenhouse gases to the atmosphere. The rise in CO level is mainly due to fossil fuel burning and deforestation. The world average CO level in 2013 was 395 ppm. This concentration is 43% higher than the level prior to the Industrial Revolution and may be the highest concentration over at least 2 million years.

Since 1750, the concentrations of methane and nitrous oxide mainly from agriculture increased by 150% and 20%, respectively.

Additional greenhouse gases contribute to global warming and its associated climate change

As the water holding capacity of the warm air increased, the global average water vapor concentration rose sharply as the global average temperature increased. Since water vapor is a greenhouse gas, the original warming is amplified. Positive Feedback

Half of the CO released into the atmosphere is absorbed by natural CO and absorbed by land and sea to help reduce emissions from human activities. One outcome of the ocean's extra carbon dioxide is a 26% increase in acidification since 1750.

Greenhouse gases contribute to the greenhouse effect that occurs when greenhouse gases absorb energy and take away heat on the surface of the earth. Greenhouse gases are essential to keep the earth warm, but if the concentration of greenhouse gases in the atmosphere is too high the temperature of the earth rises. As agriculture and fishery depend on specific climatic conditions, changes in ozone, greenhouse gases and climate change have a major impact on agricultural producers. Changes in temperature cause changes in habitat scope and planting date, and drought and floods due to climate change may hinder agricultural activities.

One of the biggest problems human beings face is global climate change. Global climate change is an increase in global average temperature caused by an increase in greenhouse gas emissions. Greenhouse gas is a gasket around the earth that makes the world reside. By capturing thermal energy in the atmosphere, this water vapor, carbon dioxide, methane and other gas layers function like a greenhouse. - Humans have a big impact on the environment. The choice of vegetarianism and carnivorism also affects the environment. Vegetarianism is the practice of excluding meat from your diet. There are six main types of vegetarianism: milk protein, vegan, longevity, fruit, raw food diet, and natural diet. The two most common types of vegetarians are milk proteins (products for consuming animals such as dairy products, but not meat) and vegetarians (no animals)

Methane is a so-called greenhouse gas. Greenhouse gases influence the environment by warming the atmosphere. The concentration of greenhouse gases has increased significantly in the past 200 years, but this is partly due to human activities. One of the biggest causes of atmospheric methane concentration is the breeding of livestock, especially cattle and sheep. These animals naturally produce methane during digestion and snoring, especially when "chewing a ruminant". As the population grows, the number of cultured animals increases significantly to meet human food demand for meat and dairy products.
