Causes of water pollution
1) Water pollution may be caused by the intentional or unintentional disposal of hazardous chemicals and materials into a body of water.
2) Rainfall may cause polluted landscapes to disperse their poisonous materials into the water and poison the surrounding water.
3) Water pollution may also be caused by specific points or contributing factors such as large factories, oil refineries, construction sites, chemical waste management facilities, dump sites and other large scale operations that store/produce large amounts of chemical/hazardous waste.
Effects of water pollution
1) Toxic rainfall can occur in areas where water and/or air is polluted with toxic chemicals and materials.
2) Polluted water can lead to sickness, disease, infections, deformities and even death among animals and plant life.
3) Once water becomes polluted it can affect people and animals either directly through consumption or indirectly through food sources, land degradation and the overabundance of plants and algae which can cover the surface of various bodies of water making it undrinkable and affecting the animals that live in that body of water.
Solution:
The most critical step to prevent water pollution is to adopt appropriate waste management policies. Setting up of wastewater treatment plants can resolve this issue and hence we can protect our natural water resources from contamination and embrace an eco-friendly life.
