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
