If someone were to say that their actions are too small to make a difference for the environment, I would say to the that "it is not too late to make a change and start helping the environment out for the mistakes that us humans have continued to cause." It is a shame to see the world slowly fade away because it was never meant to be like that in the first place. We were supposed to make the world feel like a welcoming place to all and keep the setting feel settling.
