Change is a natural part of life, both in the everyday and in the planetary sense. However, we all want such changes to be positive, and not vice versa. Alas, the compilation prepared by Google Earth reminds us that humanity still has a long, very long way to go to compensate for all the harm that we, humans, have done to our planet. However, seeing all these changes with your own eyes, you begin to doubt whether it will be possible to fix something at all.
A series of videos has been published on YouTube that show how much the oceans, forests, glaciers, beaches and cities on Earth have changed from 1984 to 2020. This is shocking.
Mato Grosso, BrazilThe state of Mato Grosso in Brazil has always been famous for its savannas and rainforests. On its territory there is a large part of the Pantanal reserve, the flora and fauna of which is unique and characteristic only for this region. Alas, in recent years, Mato Grosso has experienced major environmental problems: forests are being cut down here, and serious fires will occur.
According to scientists, in the period from 2004 to 2011, the loss of habitat in Mato Grosso was 0.76% annually. WWF has listed this ecoregion as “vulnerable”.
In the fall of last year, violent forest fires occurred in Brazil. The outbreaks were also recorded in the natural park of the state of Mato Grosso: the forests were consumed by the flame at great speed. The fire destroyed about 50% more forest in the Brazilian Amazon than a similar fire in 2019.
Columbia Glacier in Alaska, USAColombia is one of the largest and most powerful glaciers on Earth. However, for some time now, it has been rapidly melting, losing 2 cubic miles annually. As a result of this process, the ocean receives as much fresh water as one American state consumes in a year.
The Columbia Glacier has been receding since the early 1980s and is considered one of the fastest in this regard.
Shanghai, ChinaShanghai is the largest industrial center of the Middle Kingdom, which, as you know, is usually called the economic capital of China. In this gas-polluted densely populated city, there are about 13 thousand enterprises that produce about 7% of all industrial production in the PRC. Since 1949, the scale of industrial production began to grow in the city.
And for some time, Shanghai has been cleaned up as the largest chemical industry center in the country. Its enterprises produce mineral fertilizers, chemical fibers, pharmaceuticals.
Greenland iceOnce cold, ice-covered Greenland is becoming less icy. In recent years, each summer in these Arctic regions is longer than the previous one; the melted ice cover does not have time to fully recover during the winter. And if most of the population of our planet does not particularly feel the results of global warming, then the Greenlanders see it clearly.
Atsimo-Andrefana, MadagascarToday in Madagascar there are serious environmental problems, the main one of which is the rapid loss of forests. This is most eloquently seen in the example of the Azimo-Andreefana region.The reasons are slash and burn agriculture, soil erosion and degradation, as well as an increase in the volume of garbage and a lack of knowledge of the local population on how to properly handle waste.
Local forests suffer from deforestation, and their inhabitants - from poaching. Due to environmental problems, many species of flora and fauna are under threat of extinction. Forests that once abundantly covered a third of the island are now either degenerated, shattered, or transformed into islands of shrubbery. By the way, local residents actively cut down trees to get charcoal to heat their homes and to cook food on the fire.
Province of Sara, BoliviaFor the period from 1990 to 2000. Bolivia lost an average of 173,994 hectares of forest annually, and from 2000 to 2010 - 243,120 hectares a year. Local forests and overgrazing of livestock, and intensive mining, and the development of transport infrastructure are also spoiling.
In 1984, the province of Sara in Bolivia looked like a green area covered with forest. Now it is built up with houses, plowed up: the picture shows that little is left of the former forests.
Aral Sea, KazakhstanToday, the Aral Sea is only 10% of its size 60 years ago.
Recall that the reduction in the area of the sea occurred due to the fact that a large-scale agricultural irrigation project was carried out here, associated with the development of the cotton industry in these regions. They began to take water from the large rivers that fed the Aral Sea. The fish began to ache, the sea gradually became shallower.
