These photos show how much the world has changed in just a few years.

The world changes so much every day that we hardly notice it in our daily lives.

Time seems to fly by. As we get older and more familiar with the world, our brains process moments much more slowly than when we were younger. Time is always changing things in ways that are right in front of us, and are hard to notice. In just the past few years, the world has changed so dramatically that you will be surprised to see these comparison images:

1. Glaciers in the Swiss Alps have been covered with tarpaulins.

The beautiful Swiss Alps have always been a source of artistic inspiration for their picturesque landscapes. However, they have recently lost their grandeur as the Earth experiences more heat waves and warmer climates. The Swiss government has decided to preserve the remaining mountains by covering them with giant polyester tarps to block out the sunlight.

2. The Dead Sea is slowly being eroded by salt

The Dead Sea is a majestic salt lake in the Mediterranean, with super alkaline water that allows people and animals to float on the surface. However, its 'magic' may be literally dying as the sea water is constantly evaporating at a rate of 0.91 meters per year, causing more and more salt to appear in the sea.

3. Owls have recently changed their colors to adapt to warmer climates.

The tawny owl is a species of owl common in cold regions. They are born with light brown or gray feathers with dark markings. Recently, scientists have observed that tawny owls have developed darker feathers in response to warmer winters. The tawny owls have increased in population, while the grays have declined.

4. Southeast Asia's beaches are getting cleaner

Southeast Asia is a region famous for its vibrant tropical landscapes and, more importantly, its beautiful beaches. But because so many people travel there, many places are polluted and littered with garbage.

However, in the recent past, the beaches have been cleared of plastic waste. At the same time, the impact of the Covid-19 epidemic has also reduced the number of tourists and significantly reduced the pollution of the coast.

5. Many places no longer sell large fries.

Many French fries enthusiasts have been disappointed as many caterers have had to adjust their menus and portion sizes, stopping selling large fries as a result of the ongoing global potato shortage. Fast food giant McDonald's, for example, has cut the large fries option from its menu in several countries and is only offering one size of fries.

6. The clouds are getting thinner and thinner.

Clouds provide shade to reduce the heat of the sun. These natural sunblocks are fading faster as the atmosphere warms. Researchers say the whiteout effect of clouds could soon change, causing more global warming.

7. The Yangtze River is in drought

The Yangtze River, one of China's largest and Asia's longest rivers, has provided water to 400 million Chinese people over the years. However, it has been receding rapidly over the past three months and has become noticeably dry. Studies have confirmed that this is the river's worst drought on record.

8. Maldives is about to complete the construction of a floating city to save itself.

As many people know, the resort paradise of Maldives is facing the risk of disappearing completely in a few decades due to rising sea levels. The Maldives government has decided to take matters into its own hands and has begun building an environmentally and climate-friendly floating city to defy the laws of nature.

9. The Taj Mahal is almost completely covered in fog.

The Taj Mahal is India's iconic tourist attraction. Lately, thick smog has been covering the site, making it almost impossible to see from a distance. Pollution has also turned the palace's white marble yellow.

10. More people own pets

Pet ownership is on the rise in households around the world. The percentage of households owning dogs and cats in the US is expected to increase significantly from 67% in 2019 to 70% in 2022.

11. Pandas have returned from extinction

Despite appearing on our Internet feeds almost every day for their cuteness, giant pandas were declared endangered by wildlife experts nearly three decades ago. However, thanks to the tireless efforts of panda conservationists, these furry friends have been removed from the critically endangered list.

12. More and more people have poor eyesight

In 2021, a total of 2.2 billion people worldwide were reported to have low vision. This is a marked difference from the 2020 data, when statistics showed that only 1.1 billion people had vision problems. Experts point out that the change in lifestyle in the modern, technology-driven life forces us to strain our eyes, causing vision to deteriorate faster and more severely.
