It is impossible to return to the original parameters, and scientists are learning to apply new techniques to manage the irreversible consequences. Many scientists believe that we have entered a new geological epoch, the Anthropocene, with humans as a major determinant of Earth's ecosystems.
  
Excessive interference with nature has caused many problems, including the emergence of invasive plant moible number data and animal species. These species are introduced into new soils either accidentally or intentionally, posing a serious threat to native flora and fauna. Pulitzer Prize winner Elizabeth Colbert spoke about the possible solutions to this environmental problem and other consequences of human activity using cutting-edge technology. A chapter from Elizabeth Colbert's book Under the White Sky is published.

In the middle of the century, they were brought to the Caribbean. The idea was that the toads would eat beetle larvae that were destroying sugarcane, the region's main cash crop.
