Uprooting the Cause for Increasing Natural Disasters.
As the years passing on, we have got to see more and more natural disasters, which can also be said that nature has started reflecting the damages made by we humans. If we see the data of natural disasters from the past 10 years as per wikipedia, not even a single year nature has failed to show its devastation.
|2011||15,897||Tohoku Earthquake and tsunami||Tokyo|
|2013||6,340||Typhoon Haiyan||Phillipines, Vietnam, China|
|2015||8,964||Nepal Earthquake||Nepal, India|
|2017||3,059||Hurricane maria||Puerto Rico, Dominica|
|2018||4,340||Sulawesi Earthquake and tsunami||Indonesia|
|2019||1,303||Cyclone Idai||Mozambique, Zimbabwe, malawi|
Let’s start with the latest devastation Nisarga which occurred in Maharashtra’s Raigad district around 12.30 PM on Wednesday, raging through the coastal district for three hours. It has killed at least four people, uprooting trees and electricity poles, and causing power outages in many areas, including in the resort town of Alibag, but not much damage was seen in Mumbai. This is the only second time since 1902 that a cyclone that developed over the Arabian Sea.
Before this disaster, In Eastern India that is in West Bengal and Orissa, also in Bangladesh in May 2020, stroke with super cyclonic storm killing 118 people named Amphan. Amphan was originated from a low – pressure area persisting a couple of hundred miles (300 km) east of Colombo, Sri Lanka, on 13 May 2020. It was estimated that Amphan’s 1 – minute sustained winds to be 155 km/h (100 mph). The devastation cost $13.2 billion in West Bengal as per government source.
The next devastation faced was in the United States which was experiencing a busier than average start to the tornado season, with 456 reported tornadoes – of which, 398 have been confirmed as of April 23. This is higher than the average of 322 confirmed tornadoes through the end of April and approximately one-third of the annual average 1,253 confirmed tornadoes.
I wonder why natural disasters are increasing year by year?
I found an interesting answer from National Geographic stating that Climate change is the reason which makes the weather patterns more extreme.
I am not saying that all-natural disasters are caused by humans, but yes, natural disasters are being caused by humans too. Some of the natural disasters such as earthquakes and tsunamis are caused due to the movement of Earth’s Crustal plates. Variation in solar radiation entering the atmosphere and oceans triggers storms in the summertime and blizzards in winter.
As per the article of conversation.com, there are 3 reasons for natural disasters which are not natural disasters.
The First reason is the Interference of humanity with the Earth system, which can also be said as anthropogenic climate changes add more energy to the system.
Now let’s understand what is anthropogenic climate change. Anthropogenic climate change is the climate change caused due to human activities. You might wonder how human activities will affect climate change.
Since the start of the industrial revolution in the mid-eighteenth century, human activities have greatly increased the concentrations of greenhouse gases in the atmosphere. The measured atmospheric concentrations of carbon dioxide are many times higher than pre-industrial levels.
Let’s understand better! The human activities which have caused greenhouse gases are burning fossil fuels, farming and forestry, cement manufacture, and aerosols.
I have elaborated a few human activities such as:
Burning Fossil Fuels
The current Carbon dioxide levels are substantially higher than at any time in the last 7,50,000 years. As previously discussed that the industrial revolution in the 18th Century, the combustion of fossil fuels has elevated CO2 levels from a concentration of approximately 280 parts per million (ppm) in the atmosphere in pre-industrial times to around 387 ppm today.
The rising emissions of methane and other greenhouse gases, and the associated feedback effects, it is suggested that these changes may cause an increase of 1.4 – 5.6 C between 1990 and 2100.
Farming and forestry
Agricultural activities such as livestock digestion, manure use, paddy rice farming, land use and wetland changes, pipeline losses, and vented subsurface landfill emissions all lead to higher methane atmospheric concentrations. The user of fertilizers can also lead to higher nitrous oxide (N2O) concentrations.
According to the United Nations, livestock is responsible for 18 percent of the world’s greenhouse gas emissions. This percentage includes the effect of deforestation to create grazing land, as well as livestock natural methane gas emissions. In the Amazon rainforest, 70 percent of deforestation is specifically carried out to create grazing land.
Like this due to various human activities has caused anthropogenic climate change. So, to reduce the natural disaster and also to continue the human wellbeing, we human being should bear the responsibility and obligation to guard the nature as well as save our mother land. Especially today’s youth and youngsters have the ability and capability to come up with ideas and contribute to saving our world.
