C. the human population has grown exponentially

b. water pollution

Explanation:

A population that gets all the food it needs will increase faster and faster because the more individuals, the more mouths and therefore the more food consumed, leading to greater growth of the entire population. This type of growth is called exponential growth. Exponential growth is characterized by a constant percentage increase over a period of time. We can say that the population grows exponentially and for that reason, there is a constant concern to increase food production in the world, without distributing natural resources.

Water pollution is a serious and dangerous thing that happens constantly on our planet. Although many people believe that only garbage pollutes water, factors such as chemical runoff from fields, oil spills and erosion are extremely polluting to bodies of water.
