Earth is made up of more water than land. Over three quarters of earth in fact is water that includes oceans, lakes, rivers, and even glaciers. There is also water under the surface of the earth which is called groundwater which is considered fresh water. Fresh water technically can support up to 20 billion people but at the rate we are going it will not be able to service that many people. There are some difficulties we run into when dealing with fresh water. Most fresh water is not easily accessible when it is in the form of a glacier or permafrost. Where there is accessible water, it isn’t located where it is in demand, and water pollution can ruin a lot of our fresh water and make it unusable.
Pollution of our fresh water is an ongoing issue in our world. Our human living conditions cannot sustain completely clean water because of many reasons such as mining, forestry, and many more. Also when our waste comes in contact with fresh water it creates bacteria within the water that can lead to many water bound diseases like cholera, polio, parasites, and sometimes cause diarrhea. . Contaminated water caused by sewage happens more so in countries that belong to the far periphery because since those countries have a lower economy than countries such as Canada they usually cannot afford to have proper plumbing and therefore people dump their sewage into fresh water places because of nowhere else for the sewage to go.
