Negative shades of overfishing in ecosystem

Overfishing is one of the worse human action which involves catching more fish from the water than is maintainable. Such practices have negative repercussion of decline in these species, which can happen rapidly and challenge the ecosystems and may affect the stability of the environment. Several scientists have speculated that increasing overfishing may collapse the marine sea food in coming years.

 

Key concern with the practice of overfishing by human is that it exhausts marine creatures in the water that disturbs the ecosystems and has dangerous environmental aftermath.

Technical modernization in every arena made human life simple as well as it also threatens to environmental health. Advanced fishing equipment and procedures and huge vessels facilitate fishermen to capture large amount fishes for commercial use. Such fishing operation results in declining species in ocean and fishermen and boats roam to new location to go deeper in sea to capture fishes. This has devastating outcome for ecosystems. Other negative effects of overfishing is scarcity of food sources for other marine species. Such actions may have dangerous consequences in terms of decrease in number of marine animals.

Continuous overfishing operations may damage ecosystem and lead to dead zones in which oxygen level is low and organism survival is difficult. It can be understood that overfishing has negative impacts on the environment because it disturbs the equilibrium of the marine food webs.

It is imperative to take initiative to stop overfishing.

Best way to prevent practices of overfishing to lessen the consumption of sea species. Another effectual process to curb overfishing is that Governments and international organizations must jointly make efforts to implement legal policies to stop illegal fishing, give support to marine subsidiaries to promote sustainable fishing, and devise strategies so that overfishing can be controlled. Government also facilitate organization to develop more Marine Park to save fishes and help them for reproduction.

 

Final note:

In a critical analysis, it is well grasped that overfishing in oceans is alarm for forthcoming disaster at global scale. Overfishing is a detrimental human operation which threatens the whole ecosystem. Marine scientists are worried about overfishing as it can reduce the remaining fish, as well as affect their reproduction. When fisherman continuously capture fishes from ocean, it will corrode food web that creates imbalance in ecosystem and annihilation of some marine creatures.

 

Survival tactics during Blizzards

Natural disaster hit global populace in diverse forms and leave devastating impact in which human survival is endangered. Among them Blizzard cause massive destruction in affected areas. Blizzard is an intense weather event in which snowstorm along with strong winds result in blowing snow and low visibility with low-temperature weather.  Major elements that distinguish a blizzard from other snow storm are wind speed and perceptibility. The National Weather Service explained to blizzard as, “A storm in which wind speed is more than 35 miles per hour (mph) and visibility is less than a quarter (1/4) mile". Such atmospheric conditions continue at least few hours. Blizzard is deadly snow storm and has devastating impact on human society. 

The main cause of prevalence of blizzards is collision of a mass of warmer air with a mass of very cold air. The crash of the air masses activates the atmospheric tension required for high wind speeds. There are regular and ground blizzard that hit in natural atmosphere. In ground blizzard, strong winds lift and blow loose snow or ice on the ground. It is different from regular blizzard, in which there is no precipitation at that time, but it is present at the surface in the form of snow or ice.

 

Blizzards has dangerous consequences in cities. It can disrupt traffic and communication. Due to strong wind speed and snow, power lines can fail and can create shortage of food and water if the blizzard is continued over a long duration. These devastation may derail the life of people. Additionally, people injured during Blizzards may not get urgent medical treatment.

 

Precautionary measures: 

There are some preventive steps that people must take to survive. When there is prediction of Blizzards by weather experts, people must adopt safety measures such as avoid any travel, stay indoors, and keep ample amount of eatables, drinks and ensure appropriate supplies of heat. Basically traveling during a blizzard is unsafe because strong winds, slippery roads and low visibility increase the chance of accident. It is important to prepare emergency medical kit in which there are medicines to treat chronic conditions, such as asthma, high blood pressure, or diabetes. Other major problem during blizzards is wreaking havoc of power lines. High speed of the wind and snow may disrupt power supply, break branches and trees. It is necessary that flashlights, batteries, candles, a portable phone charger, and plenty of blankets and warm clothes should be handy. Some people try to use risky procedures to heat their homes such as charcoal and gas grills that can create large amounts of smoke which is dangerous for human health. It is recommended to stay hydrated and remain warm to have proper oxygen for good health.

 

People are advised to adopt proper government guidelines to keep warm their home and remain properly dressed when going out for any urgency such as wrapped body with warm clothes, a hat, a scarf, gloves, thick socks and boots to protect ears, nose, fingers, and toes. It is always better for all residence in hit areas of blizzard to be updated with news for storm warning.

 

Closing thoughts: 

Rolling up significant facts about Blizzard, it is well established that Blizzards is an extreme meteorological conditions that has capacity to wreak havoc on life and property. Blizzard hit in atmosphere when the air temperature is near or below the freezing point of water. Meteorologists explicated that Blizzards is the outcome of collision of warm air with very cold air. During Blizzards, it is advised that people must stay at home and stock up sufficient food and water for survival. Preventive measure during worse hit natural disaster is the only way for people to remain safe.

Ocean acidification deteriorates human health

 Oceans are beautiful gift to people in this planet. Oceans are media for trade and voyage from one country to other and for pleasure in world. Humans and water entities get oxygen and maintain good health if oceans are free from pollution. Oceans are responsible for regulating climate which in turn give huge benefit to living organism. In brief, the ocean offers good resources to improve human health that include food, oxygen, livelihoods, blue spaces, and medications. Recently, climate scientists have observed intense threat to such natural resources due to increasing ocean acidification. Human’s bad practices worsen the level of pollutions in oceans. Earlier, ocean acidification pose threat to the marine arena only but currently, it becomes a major human health issue among climate researchers and experts. Several scholars have realized that ocean acidification massively impact on the resources that are responsible for human health. Ocean acidification leads to malnutrition and poisoning, respiratory problems, and mental health illness.

It is evident that carbon dioxide (CO₂) accumulating in the world’s oceans and leads to ocean acidification which is major health hazard to global populace. Humans poor practices such as burning fossil fuels and drive deforestation results in increasing CO₂ in the atmosphere  which pollutes oceans and leave negative impact on living beings. Adult exposures to polluted oceans may increase the chances of cardiovascular disease and dementia. Plethora of researches also indicated that due to this environmental degradation, when people consume contaminated seafood, it can damage developing brains, diminish IQ and increase the risk of autism in children, ADHD and learning disorders.

As acidification increased, living organisms have to put more energy to maintain their acid-base balance, metabolic processes, or other biological functions for their growth, reproduction, and existence.

Environmental researchers and world leaders have to recognize this issue as an emergency basis. They must explore numerous mitigation and adaptation management policies that can be implemented to curb oceans acidification and offer health benefit to global people. Main mitigation approaches is to execute strategies that aimed  at  the  lessening  the  energy  use  by  industrial  sectors,  decrease  of  net greenhouse gas emissions, decarbonisation of energy supply, and carbon capture and repossession through the improvement of natural sinks or engineering practices.

At bottom line:

To encapsulate the facts of ocean acidification and its harmful impact on human health, it can be appraised that today, oceans have faced unprecedented challenges due to some poor human actions that pose danger to their wellbeing. In natural sphere, marine and coastal biodiversity offers huge benefits for human health. Oceans are very important for livelihood of humans and global geo-chemical processes, such as climate regulation. But rising level of carbon dioxide in the atmosphere results in ocean acidification and is key concern for climate scientists. It directly affect wellbeing of humans and lead to numerous serious illness like mental health disorder, respiratory issues. Therefore government and other environmental organizations must tackle this severe environmental issue to provide protective covering to global community and improve their health.
