The main components of greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons (CFCs), hydrofluorocarbons, etc. Methane gas is one of the seven most important components of greenhouse gases. Methane emissions are largely responsible for the climate crisis or global warming. As we know, carbon dioxide, chloro fluoro carbon emissions are the main source of ozone depletion in the atmosphere. But scientists have recently changed that idea. According to BBC News, U.S. researchers have warned that if methane emissions are not brought under strict control, the current fight against climate change will not have much effect. Because methane gas can hold up to 30 times the temperature of the atmosphere over a century, compared to carbon dioxide.
Robert Jackson, a scientist and researcher at Stamford University in the United States, says: There are enough reasons behind this. But if we don't look at methane now, that risk will go away. '
From the above analysis we have learned that the effects of methane gas to increase surface temperature and accelerate climate-crisis are very serious. Therefore, scientists have called for efforts to reduce methane emissions quickly.
The main source of methane gas is fossil fuels. Natural gas, industrial waste, burning coal, cow dung, methane gas are emitted at higher rates from waste disposal. We have also come to know about the production of methane gas from paddy plants and water bodies. However, it is not yet known how harmful that rate is. However, it is known that the presence of methane gas in the sky of Bangladesh. It came up in a study by a Paris-based organization called Cairo SOS on 6.4.2021. On the other hand, on 25.4.2021, quoting GHGSAT, the influential US media 'Bloomberg' reported in a report that the garbage dump in Matuail, the capital of Bangladesh, is one of the hotspots for methane gas emissions! Of course, there is little debate on the issue.It is unknown at this time what he will do after leaving the post. So we are not going into that debate for now. Rather we are trying to learn about the harmful aspects of methane gas. Studies have shown that methane gas is one of the most harmful greenhouse gases. Methane gas is the gas that is produced by the decomposition of various organic substances. This gas is being produced in almost every country in the world. Bangladesh is not solely responsible for this; Methane is also being produced from countries that are producing rice. Methane is being released as a result of the bacteria in the soil producing huge amount of gas while irrigating the paddy field. In addition, industrial wastes, cracks in natural gas lines, polluted fumes, and mineral fuels are increasing methane levels. Which is spreading in the wind.
But no matter how methane gas spreads, it needs to be brought under control. We have to be diligent. Because it is a very deadly gas. As a result of its circulation in the atmosphere, the environment is being severely damaged.It is known that in the last 20 years, methane gas has caused 70 times more damage to the environment than carbon dioxide. As the ozone layer is being damaged, so is the climate crisis; The effects of methane are also increasing global warming. Not only that, but because of the effects of methane, deer, a species of reindeer in the Arctic region, are becoming smaller and smaller, losing weight and dying at an early age. Many species of animals around the world are under threat today due to increasing methane emissions. After reviewing and researching various issues, scientists have made it clear that methane emissions need to be reduced rapidly. They have set a target to ensure that the temperature of the atmosphere does not rise more than two degrees Celsius from the current level. Otherwise, the world will face a crisis due to the collapse of the glacier, as well as the sea level will rise and the lowlands will be submerged in water - Bangladesh is one of them. So we play a role in preventing global warming by controlling waste disposal and the use of fossil fuels. At the same time, we are hopeful that scientists will find a quick way to reduce the rate of methane emissions to zero in agriculture and cattle rearing. Because, in order for a person to survive, he has to think about his food security first; Then another issue.
