These words are said by Mahatma Gandhi and I am agree with this statement that people with increasing demand can never be satisfied with the resources provided by the nature. Here are the reasons in the support of this statement.

1. Cutting of trees and Deforestation: Due to the increasing demand for accommodation and luxurious lives in, humans are cutting trees to construct the building and luxurious apartments.
2. Animals Killing: To fulfill the unnecessary fashion demand and animal based diet humans are killing animals which is affecting the climate.  
3. Greed of having more: The demand and unending choices are increasing day by day which resulting in destroy of nature and over-exploiting the limited resources.
4. Technological advancement: Making of refrigerators, air conditions, cars and etc are polluting the environment and making hard for other living animals to live freely on this earth.
