Human life has been dependent on nature for economic prosperity. Humans started exploring it to meet many of their needs. As the population grows, so do the needs. The demands of humans turned unprecedented. They started exploiting nature without a thought for the future. They built factories that emitted harmful gasses into the air.  Humans have cleared forests to extend agricultural lands. All of this led to global warming and pollution. On the other hand, most of the natural resources were depleted due to excess stress on them. They have ended us up on an unsustainable path. Now, humans are turning towards a sustainable way by adopting non - renewable energy practices.
