A new study published in the journal Nature has revealed that the climatic changes and destruction of natural ecosystems may be an indicator of a permanent change in the biosphere, as per a report.

Researchers from the University of California have studied the impact of global changes on Earth. Comparing the data of the past to the present processes, the team concluded that a new world in terms of biology would be seen within a few generations.

It is being said that some species would be extinct as a result of growing population and natural changes, while remaining species would form some new mixes. Also, it is being said that it would be difficult to decide which crops should be grown where.

Anthony Barnosky, Professor of integrative biology says, "The data suggests that there will be a reduction in biodiversity and severe impacts on much of what we depend on to sustain our quality of life, including, for example, fisheries, agriculture, forest products and clean water”.

Thus, the team suggests that better predictive models are an urgent need of the hour so as to study and understand what caused biosphere to react to rapidly changing global conditions.
