Water is a precious commodity on the face of the earth. However, there are various factors that pose threats to earth’s water supply. Among the major factors are the human beings. Their constant increase in population, as well as the activities they undertake, contribute to making water supply to the earth scarce.
Expansion of the population
Human beings are themselves a threat to earth’s water. The human population is quickly expanding. This means that there is an increased demand for water since we all need water to sustain ourselves. This has, in turn, put pressure on the available water sources which have to continually supply to the ever-growing population. Besides that, the ever growing population is also putting a strain on several other resources like land since the demand for space is leading to deforestation.
Deforestation and the destruction of vegetables
Human activity is also a threat to the earth’s water. When the population of human beings grows, it leads to demand for more space for construction hence forests has been cut down to create more room as we grow in numbers. Trees have been of importance since they help in preventing evaporation of the water bodies which we depend on for water supply. Deforestation due to the settlement, farming, and logging have negative effects since they leave the land bare encouraging the evaporation of the water bodies. Deforestation has also led to significant changes in the climatic patterns which have seen the rainfall amounts dwindle over the years. The less the rainfall, the more the shortage of water will hit us as we go into the future.
Air and water pollution are also a threat to the availability of earth’s supply of fresh water. Industrialization and increased number of motor vehicles using sulfur based fuels have seen the emission of poisonous gases into the air leading to the formation of acidic rain. Acidic rain produces acidic water which threatens the supply of fresh water to the earth. Dumping of wastes has also seen the poisonous chemicals being absorbed by the soil hence producing acidic water from the wells.
The consequences of pollution of the water, air, and soil have caused a disruption of the food chain which will eventually lead to the extinction of some organisms from the face of the earth. This disruption has got its consequences on the general life as well.
All these forms of pollution continue to threaten the availability of fresh water. This calls for us coming up with other sources of energy that are environmentally friendly so that we conserve the air and water.
From the above, it is clear that as human beings we have the sole responsibility to ensure we have a constant water supply especially the fresh water. Adopting some practices such as planting two trees for every one cut will help in ensuring that the land cover is protected. Afforestation will also help restore the previous climate patterns before people started doing lumbering. It is also never too late to use the greener energy sources.
