"Agricultural Processes"

TASK 2 MODEL

Modern agriculture often involves using large quantities of artificial chemicals and sophisticated technology.

What are the reasons for these developments, and what are some of the effects?

The mass production of food to nourish ever increasing populations has necessitated the use of modern technologies in agriculture. A variety of chemicals are now employed as pesticides and fertilizers to protect our crops and improve yields. It is important to note that there are a range of consequences linked to the changes in way we produce our food.

The world's population has now expanded to more than 6 billion people. With the growth in population has also come an increased need for food. Essentially, this means that significantly more food must be produced more efficiently. Insecticides are part of the solution as these extensive crops require protection to ensure mass production.

However, we should remember that the chemicals we use in food production are inevitably consumed when we eat our food. There is no escaping the fact that residual chemicals from agricultural processes will eventually find their way into our bodies. Unfortunately, many of the pesticides used are not only highly poisonous to insects but also highly toxic to people. Scientists cannot conclusively say that pesticides are harmless and it is true that some of these chemicals accumulate in the body until they reach dangerous levels.

The use of fertilizers can also have adverse impacts. Chemicals such as phosphates are added to the soil to enhance yields, but much of this chemistry is washed into rivers and eventually flows into the ocean. The inevitable pollution of our oceans is the end result of this process.

To conclude, the mass production of food does bring with it some negative consequences. We need to find cleaner and greener pesticides and fertilizers to ensure the health of our people and the cleanliness of our oceans.
