Our natural resources are generally classified into renewable and non-renewable resources. We are more depended non-renewable resources for most of our needs and this is our biggest downfall. The biggest one being resource depletion, where the resource is being exhausted faster than it can form.
Furthermore, non-renewable resources cause a lot of pollution, and this can have a detrimental effect on the environment. This is very evident in places that are highly populated – the people that live there are prone to various pollution-related illness and disease.
