Research: Earth’s ecology has changed dramatically over the past 70 years

A group of scientists from the United States compared the influence of man on the planet over the past several thousand years. It turned out that the most dramatic changes have been taking place since 1950.

A new study, coordinated by the University of Colorado in the United States, found that since 1950, Earth’s population has accelerated the rate and extent of energy consumption, economic productivity, and population size. These and several other factors pushed the Earth into a new geological era – the differences in physical, chemical and biological changes in the layers of the Earth’s rocks discovered during research began around 1950.

An article published in the journal Nature Communications Earth and Environment documents the natural drivers of environmental change over the past 11,700 years and the dramatic changes that have taken place since 1950. The planetary changes of the last 70 years have affected oceans, rivers, lakes, coastlines, vegetation, soil, chemistry and climate.

For example, over the past 70 years, energy consumption has exceeded all the previous 11,700 years – mainly due to the combustion of fossil fuels. This huge increase in energy consumption has resulted in a dramatic increase in population, industrial activity, pollution, environmental degradation and climate change.

18 authors assembled existing research to highlight 16 major planetary changes caused by increased energy consumption and other human activities that have been of great importance since 1950.

Since 1950, humans have also doubled the amount of nitrogen on the planet through industrial production for agriculture, created a hole in the ozone layer through emissions of chlorofluorocarbons (CFCs), produced massive amounts of greenhouse gases from fossil fuels to cause global climate change, created there are tens of thousands of synthetic compounds on Earth that look like minerals.
