  • As the world’s population continues to grow, more resources are used up. There is an abundance of people who live in poverty and do not have basic supplies, while there are others who possess a majority of said resources.

  • A quarter of the Earth’s population is responsible for over-consumption, or using more resources than is necessary. Over-consumption is one factor that leads to the pollution of the environment.
