Present economic system has created an ecological system that is clearly unststainable

The Earth is not simply ‘dying’ because of climate change (Express, March 22). It is more correct to say that it is being destroyed by an economic system, namely global capitalism.

It is ravaging the planet in search of profits, causing not only atmospheric pollution (carbon emissions) but also a serious loss of biodiversity, largely through de-forestation and industrial agriculture.

As Vandan Shiva and other radical ecologists have been emphasising for the past 40 years, the present economic system has created an unprecedented ecological crisis and one that is clearly unsustainable in the long-term
