Answer -
Environmental crisis is indeed a recent phenomenon. Before industrialisation there was less demand for environmental resources as there was less population and it was able to sustain with the resources, it was surplus for the existing population. As there was less exploitation of resources so the rate of regeneration was much faster. But in present day due to population explosion, rapid urbanisation and over exploitation of natural resources the nature is unable to replenish the stocks, which is causing ecological imbalance that is putting pressure on environments carrying capacity giving rise to environmental crisis.
