Where is the water in the world?

Where is the water in the world?
The earth is made up of approximately 70% water. about 90% of the water is in the oceans and the rest is in the form of fresh water, ground water and glaciers.  The figure below obtained from http://ga.water.usgs.gov shows a representation of the distribution of water in the world.

 

Majority of the water in the world is located in oceans, which are mostly salt water. Most of the freshwater in the world is located in all parts and regions of the world. The bodies of freshwater include lakes, ponds, rivers, streams and wetlands. There is not a continent on the planet that does not have at least one of these bodies of freshwater.

Accessible water is a very essential part of life. Unfortunately, a large number of populations have little or no access to water for their daily activities such as sanitation, farming and even nutrition. The major continents affected by this problem are Africa and South America, and Asia.

Potable water is also very scarce in some South American and African countries. In some of these regions, the people have limited access to water and the few water sources are nit safe for consumption.

Contaminated water is very high in all regions of the world. Our waters, even oceans and rivers are becoming more and more contaminated as a result of pollution caused by human activities.

The map below shows the regions that have poor access to safe potable water and high levels of contaminated water.

 

2. Where in the world are the good and accessible soils for agriculture, silviculture, and farming?

The good and accessible soils for agriculture and silviculture are located in different regions around the world but unfortunately, they have decreased over the years due to excessive cultivation. Below is a map showing the soils around the world and their different levels of fertility.

3. Where in the world is traditional industry? Where in the world is the high-tech industry?

The traditional industry has been around for centuries and still exists today in many parts of the world. It is predominant in developing countries but is diminishing slowly in the developed countries. The High tech industry is taking over the industrial world and as a result diminishing the traditional industry. Traditional industries are all over the world but high tech industries are predominant in the western world.
