why are people does'nt care about the nature anymore

Sagot :

It is because they think that other people can restore the environment for them. Example: Nagtapon ng basura sa ilog ang isang tao "Lilinisin iyan ng ibang tao." Sorry for the mixed language
This is actually a really sad realisation, but I think it's because of worldly desires and riches that drive a person to being ignorant of the environment. Industrialisation contribute a lot of pollution to the environment and industrialisation is what people believe is the progress of humanity
