pollution effects on Animal Development

 

There has been a great concern on the pollution effects on the health and well being of animals. The toxicity of most of the pollutants has adversely affected the animals leading to economic loss. This has led to the need for research on the effects of pollution to the development of animals (Catcott, 1958). The paper aims at looking at the effects of air, water and soil pollution on animal development.

Air pollution

Organic compounds like the oxides of nitrogen are chemically transformed to form the ozone layer in the presence of sunlight. This destroys the lungs of animals. Acid rain made as a result of sulphur oxides combining with water in the atmosphere causes destruction of aquatic life hence kills fish in rivers and lakes. Excess UV rays causes cancer of skin among animals (The naked scientists, 2009).

Water Pollution

Nutrients such as phosphates and nitrogen lead to excess growth of toxic algae which causes death of aquatic animals when eaten. Oil pollution affects the development of marine organisms as it leads to damage of nervous system, kidney and liver. It also causes irritation of gastrointestinal system. Heavy metals such as mercury causes slow rate of growth and development of animals (Catcott, 19580. It also reduces the reproduction rate and increase death rate. Excess salts such as sodium chloride in water lead to death of many organisms.

Soil pollution

Harmful chemicals such as pesticides and herbicides alter the rate of metabolism of small organisms like arthropods which is passed on to other organisms in the food chain (The naked scientists, 2009). Accumulation of heavy metals and fluorides in soil lead to the death of soft-bodied organisms like earthworms hence reduced soil aeration which affects the quality and quantity of food hence reduced rate of animal reproduction and growth.

Conclusion

The paper has successfully highlighted some of the main effects of pollution on the development of animals. It is important for people to come up with control measures so that we can reduce the adverse pollution that leads to loss of animals.
