It is a truism to say that humans are dependent people. This is to say that all humans and human civilization are dependent on nature for sustenance. In light of this, we can name many natural resources humans need. I will name a few of the most important in our modern culture.
First, we need clean water. We take this for granted in the West, but we need to realize that it is a privilege for us to have clean water. Many places on earth do not have this luxury. This causes great struggles and hardships - and to be more accurate disease and death.
Second, we need energy. To be more specific, we need things like oil and natural gasses. These natural resoruces enable us to to travel, heat homes, and the like. As we look into the future, we can say that we will need more energy.
