Predicting the future of the Earth in 2050 makes people shiver

Urban residents tripled, half of the world's population has no water to use, millions of starving people . are problems that the Earth may face in the next four decades. .

With the development of science and technology, we have self-driving cars, or semi-smart robots. In parallel with the technological progress, humanity has been faced with numerous difficulties from epidemics, poverty, natural disasters .

According to experts, really big issues are waiting for us in the next few decades. Science and technology right now need to focus on finding solutions to make our future better because in reality, these difficulties are coming very close.

Let's review the scary prospect that the Earth will face in 2050 through the synthesis of Business Insider page.

1. Urban residents have tripled

Statistics show that in 1950, the population lived in large cities and urban areas of 750 million people. But this number has reached 4 billion people at the present time and tends to increase in the future.

Experts estimate that, in the middle of the 21st century, the population living in big cities will reach 6.3 billion people.

Along with overcrowding, the possibility of spreading infectious diseases, viruses, tuberculosis, and influenza will increase rapidly. This is in part because the water is depleted and the health is affected by not being enough for everyone.

Compared to rural areas, the city consumes about three-quarters of the world's energy and emits a large amount of carbon. According to WHO, air pollution has caused 3.7 million deaths in 2012 . This number will not stop there when the urban population increases and the pollution is increasingly heavy.

2. The number of people who die from air pollution hits 6 million people

A recent report by the Organization for Economic Cooperation and Development (OECD) announced that by 2050, the number of deaths from air pollution will reach 6 million.

The reason given by experts is that, because warmer weather will be the factor that helps increase chemical reactions that produce many pollutants.

One of these toxins is ' bad ' ozone ozone - produced by chemical reactions between nitrous oxide (NOx) and organic compounds (VOCs) that are volatile under the presence of sunlight.

Industrial emissions, vehicle engines, and chemical solvents are the main sources of NOx and VOCs . This substance will cause the inhaler to feel short of breath, causing a cough, which will cause asthma.

3. 1/2 of the world's population has no water to use

You believe, at the present time, 1.1 billion people (1/6 of the world's population) are without clean water to use and this number will increase.

According to the International Water Management Institute, by 2050, this figure will reach nearly 2 billion people , mainly concentrated in the Middle East and North Africa. Not only clean water, but a majority of water used for irrigation is also threatened.

Currently, one third of groundwater circuits are gradually disappearing . With population growth and global warming, this situation will become worse. Along with water scarcity, the world will also face droughts and forest fires at an alarming rate.

4. Countless fish we eat will become extinct

A report by the United Nations Environment Committee has shown that the level of fishing and fishing in the world is at 87% . If the world continues to maintain fishing at the current level, then by 2050, countless species of fish will be extinct.

The decline in fish numbers also makes people who depend on fishing, aquaculture lose their jobs, and the global seafood export industry will also suffer badly. This number could be up to 129 billion USD.

5. Millions of people around the world starve to death

Earth's temperature is gradually warming, alarming a severe food shortage in Africa and Asia , causing catastrophic consequences for the poor in these areas.

The amount of food worldwide has now decreased by about 2% and if it continues, within 10 years, we will lose 4.43 million tons of food.

The report of the world's largest international agricultural research organization confirmed that by 2050, food production will have to increase by 60% to keep up with climate change and global population growth.

6. Rain forests will disappear forever

Did you know, every year we lose a large amount of rainforest - that is the result of many people exploiting and deforestation indiscriminately.

Although the exact area has not yet been determined, it is estimated that at least 32,300 hectares of forest disappear from Earth every day and at least 32,300 hectares of forest are degraded.

Along with the disappearance of tropical rainforests, hundreds of species have been endangered . Not only that, when the forests are destroyed, a large amount of carbon emissions into the atmosphere will continue to change the climate.

7. The virus can cause 10 million deaths each year

The world has recently warned about the status of drug-resistant viruses with the words ' bacterial nightmare ' or 'deadly virus'.

This situation has claimed 700,000 people a year and a US scientific report has shown that infections by 2050 can kill 10 million people worldwide - more than all types of cancer. merge.

Like any living organism, bacteria can multiply as well as mutate to survive. Some species will mutate to increase their resistance to killing them.

8. The disease spreads easily

Increasing temperatures combined with floods and droughts are becoming a threat to global population health. Because this is the ideal habitat for mosquitoes, parasites, mice and many other organisms that thrive.

According to calculations by the World Health Organization (WHO), by 2030, more than 60,000 people will die from malaria. By 2050 , 4.6 billion people will be at risk for dengue fever and cholera will also grow stronger when there are 130,000 people die each year. With the immune system reduced due to erratic climate change, most likely, the real number will not stop here.

9. Storms appear more frequently and more seriously

The US National Climate Assessment Board said that the number of types 4 and 5 (the strongest types) of storms has been increasing since 1980. And according to experts, this trend will continue. increase in the direction that is difficult to control.

Specifically, climate change causes high levels of sea level and heat . Earth warms, steam rises, causing storms to become strong and intense by 300% by 2100.

10. Rising sea levels flood major cities across the globe, and power outages are common

According to experts, with the current state of carbon emissions into an uncontrolled environment, the warming of the Earth will increase sea level by about 35cm, causing many cities to be submerged in water.

A report pointed out, if global temperatures rise by 1 degree C, more than 40 out of 700 world heritage sites, the big city will be submerged in water within the next 2,000 years. If the temperature rises by 3 degrees Celsius, that number will increase to 136 heritage.

Along with that, widespread power outages also occurred.By 2050, more than 50% of people will likely have to live in the dark . This impact will make the situation worse, especially in densely populated areas like East North America like New York and Philadelphia.

11. Oil becomes a luxury item

According to experts, with high population growth, ensuring energy demand is also a concern in the future.

Accordingly, if global energy use remains at current levels, by 2050, demand for oil will increase by 110% - or 190 million barrels of oil will be used every day. At the same time, carbon emissions to the atmosphere doubled.

The exploitation of new energy sources - coal - to replace oil is also a concern. However, this is one of the most polluting energy sources in the world. Therefore, the scientific community is headache to come up with a feasible plan.
