Do you feel there will always be enough matter and energy for the survival of all individuals of all species? Will nature be able to continually absorb “waste products” from human societies?
I think that the world has limited amount of matter that humans are capable to convert to energy to meet their day to day demands. For example, the fossil fuels may end up with a century or two. In the same way, the uranium and other elements that humans use to get nuclear energy will also end one day.
I think that humans are creating an environmental imbalance and the nature may not be capable to absorb the amount of waste we produce. The only way to save the environment is to live sustainable lives and rely mostly on renewable energy source to meet our energy demands.
