What environmental worldview is seen by critics as focused on short-term economic benefits with little regard for long term harm
attashe74 [19]

It is because on continually increasing use of earth's natural capital, and it focuses on short term economic benefits with little regard for degradation and depletion of natural capital and resulting long-term harmful environmental, health, and social consequences. Environmental world views are the ways of thinking about how the world work and beliefs that people hold about their roles in the natural world, another factor is widespread lack of understanding of how earth's life-support system works, keeps us alive, and supports economies.
