Global warming is one of the biggest problems that affect the environment. So what is global warming? It is defined as an increase in temperature due to air pollution. It causes serious consequences for humans as well as other species. In this essay, I will explain more clearly the cause and solution to this problem.
Firstly, the burning of fossil fuels appears to be one of the main causes of global warming. Burning fossil fuels releases gases such as carbon dioxide (CO2) and methane (NH4) into the environment. For example, the large number of vehicles on the road, such as cars and motorcycles running on fossil fuels, emit terrible amounts of emissions, such as carbon dioxide, which creates greenhouse gases and causes the temperature on Earth to increase. Besides, factories also release into the environment often toxic emissions such as CO2, H2S, and CO. It can be harmful to human health and the environment. For example, according to a report from the Ministry of Industry and Trade, the thermal power industry is one of the industries with the largest emissions, followed by the petrochemical industry, coal mining, and metallurgy industries. These industries all emit large amounts of toxic emissions into the environment. The second cause is deforestation. This is because as the population increases, the need for housing and food sources becomes urgent. The General Department of Forestry has statistics that: On average, each year the forest area in our country decreases by 2,430 hectares. Trees help absorb CO2 and produce O2, making the air fresh. However, cutting down trees has resulted in less absorption of air pollutants. For example, there is an article claiming that CO2 levels have increased significantly due largely to deforestation and factory operations.Using too many electronic devices is also one of the main causes. Life is increasingly developing, and the need to use smart electronic devices is increasing. However, most such products emit CFCs and other carbon gases. For example, older-generation refrigerators often contain substances such as CFCs or HCFCs, which are volatile, toxic liquids and gases that cause ozone layer depletion. According to a report from the Ministry of Natural Resources and Environment, refrigerators and air conditioners often contain HFC gas, which causes the greenhouse effect and can increase global warming by 12–14.8 times CO2 gas. If these electronic devices are broken or not used, they will be thrown away in the environment, causing the amount of “electronic waste” to increase. It will lead to ozone layer depletion, worsening the greenhouse effect and global warming.
One solution that is proving successful is the use of transportation solutions. Do not use cars or personal motorbikes that run on gasoline or diesel, but instead use bicycles, electric vehicles, or public transport. For example, affordable electric cars and electric motorcycles from Vinfast are appearing on the market. Not using vehicles powered by fossil fuels will reduce emissions into the environment. For example, in the Netherlands, using bicycles for 25% of daily travel needs reduces CO2 emissions equivalent to planting 54 million new trees each year. As a result, the air in the Netherlands is clean, and substances that cause climate change are not found. Another effective solution is forest management. This is the easiest way to reduce the amount of CO2 in the atmosphere. Each individual can plant trees in the house, yard, or sidewalk, or the government can control deforestation, manage the number of existing forests, increase mobilization of forces to plant more trees, and delineate areas of land to plant trees. For example, the government has deployed the directive “Program to plant 1 billion new trees” for agencies, organizations, and individuals to jointly implement or the program “Planting trees to create forests” for students at schools in Ho Chi Minh City. Trees can absorb carbon dioxide. On average, 2 hectares of large foliage trees can absorb tons of carbon dioxide per day and release 730 kg of oxygen. The amount of carbon dioxide emitted by 1 person in 1 day will be absorbed by 10 square meters of trees. Finally, it is to encourage people to use renewable and non-polluting energy sources such as wind and solar energy. Countries such as Denmark and Germany have invested significantly in wind energy, reducing their dependence on fossil fuels. Electricity can be generated through windmills or solar energy. For example, in Bac Lieu, there is a very famous place called “Windmill Wing” with giant wind turbines. It helps create electricity for the entire West. The government also needs to educate people about the positive benefits of solar energy by providing free panels or encouraging factories to install solar panels. In addition, people should consciously reduce the use of fossil fuels to reduce greenhouse gas emissions and reduce the impact of global warming.
In conclusion, global warming has become an urgent issue for many countries, including Vietnam. Its main causes are fossil fuel consumption, deforestation, and using many electronic devices. In this article, the solutions for the issue have been proposed in three parts: using renewable energy, forest management, and use of transportation solutions. Governments and all citizens need to join hands to make a more “green” environment, contributing to reducing global warming.
