anthropogenic global warming of greenhouse gases and its consequent large-scale changes in weather patterns. Although there have been periods of climate change in the past, since the mid-20th century humans have had an unprecedented impact on the Earth's climate system and caused change on a global scale. The main contributor to climate warming is the behavior of greenhouse gas emissions. But there are two main causes: Economic growth and deforestation.
`+` Economic growth:
`-` Due to the high and rapid economic growth across the country. That not only brings the world economy to a new page, but also has a huge impact on the global environment. Economic growth leads to an increase in people's living standards. With the increasing demand for vehicles, smog and vehicle noise are part of the global pollution impact. New industries also directly affect global pollution. When factories discharge waste into the environment. The amount of smog of these factories accounts for nearly 40% of the amount of smoke and dust in the air.
`+` Deforestation:
`-` Deforestation is not only loss of ecosystems, it also erodes the soil and there is no forest to keep the land from flooding. In the process of burning forests, a large amount of CO2 is released directly into the air. The greenhouse effect is one of the problems affecting global temperature. Every household now has an air conditioner, the process of using the air conditioner and the emission of greenhouse gases into the environment. And as we all know that the higher the greenhouse effect, the more puncture phenomenon. The ozone layer also increases accordingly.
All of the above are the causes of global warming. The consequences are enormous, not just for the animals. Including people, habitats are threatened. Living conditions were low, diseases spread all over the land. Therefore, each of us should join hands to reduce the global warming process. The Earth is warning people with storms, floods, droughts and let's answer them. By doing things to protect the surrounding environment, this hourly warming will be reduced.

According to scientists, human influence is the number one cause of global warming effects, especially deforestation and increased carbon emissions from burning fossil fuels. Human CO2, methane and other chemicals are released into the atmosphere acting as a veil, capturing the heat from the sun and causing the Earth to heat up. This changes the Earth's climate system, including land, atmosphere, oceans and ice. Higher temperatures also cause more natural disasters such as storms, floods, heat waves and droughts to become stronger.Prolonged heat spells make the soil dry, causing scarcity of clean water, widespread wildfires, dust storms and flash floods. In many parts of the world, the lack of water leads to serious epidemics. On the contrary, heavy rain caused rivers and lakes to overflow, destroying houses, polluting drinking water, spreading waste and polluting the air. At the same time, hot and humid conditions also facilitate the spread of disease through water and food development, as well as the transmission of insects such as mosquitoes, lice ... grow.Increasing temperatures also make air pollution worse due to the thickening of the ground ozone layer (when emissions from vehicles, factories, other sources respond to sunlight and temperature). The ground ozone layer is a major factor in photochemical smog and the higher the temperature, the thicker the fog. Dirty air causes an increase in the rate of hospitalization and death in asthma patients, making people with heart or lung disease worse.When the ground and ocean undergo rapid and powerful changes, animals and plants will disappear if they do not adapt. Many terrestrial and aquatic animals have moved to cooler regions or to greater heights to escape global warming. They also change seasonal behavior and migration rules. However, many species still face extinction. A 2015 study found that vertebrates (fish, birds, mammals, reptiles, amphibians) are disappearing at 114 times faster than normal - a phenomenon that is closely related to climate change, pollution and deforestation.Polar regions are particularly sensitive to global warming. The average temperature in the Arctic is more than twice as fast as other regions and the ice is melting rapidly. This not only seriously affects people and regional flora and fauna but also causes sea level rise. It is expected that by the year 2,100, the sea will rise about 30 - 130 cm, threatening coral reefs and low areas of the world. Island nations and big cities like New York, Los Angeles, Mumbai, Sydney, Rio de Janeiro ... will be submerged. Besides, seawater is also more acidic, largely due to absorption of emissions. If this concentration continues to rise, marine ecosystems will face a great risk of extinction, especially shellfish or bones such as molluscs, crabs and corals. Clearly, climate change makes the future of humanity become fragile. The scary thing is that it's too late to turn anti-clockwise, when we emit huge amounts of emissions. Even if all activities stop producing CO2, people will still have to face the consequences. However, if we actively reduce global emissions, the consequences of climate change will be less.
