范文:
In the last a few decades, people’s requirements on food have experienced a series of changes. When the problem of food scarcity has been solved, people are on the way to improve the taste, such as by innovating cooking method. But today, a new problem associated with food emerges: the decline of quality.
To begin with, as we are accustomed to the mass production of food and believe in its benefits of feeding large population, we cannot overlook the fact that some of the food we have today is actually not as nutritious as before. To meet the huge demand of food, scientists and food producers, including farmers and factories, have adopted a series of scientific methods to boost output, such as widely applying fertilizers in fields and raising large numbers of livestocks in cages. Though the benefits are undeniable, the products actually contain fewer nutrients due to the factitious changes of their natural growth. With shortened lifecycle, both crops and livestocks have not enough time to accumulate nutrients. Therefore, wealthy people today would like to pay a higher price for so-called organic food, food produced in natural ways, which actually is what all people had in the past.
Secondly, pollution is another factor influencing food quality. The rapid industrial development has generated pollution of different degrees in many areas and regions around the world. Pollution knows no boundary: the uncontrollable movement of water and wind carries pollutants worldwide. For instance, the burning of coals containing high percentage of sulphur in one place releases sulphide and cause acid rains in a much larger areas. Continuously, the contaminated rains pollute soils that they fall on and rivers that they flow into. Unavoidably, many plants and animals living in a contaminated environment contain more or less elements harmful to people’s health. Currently, one of the most seriously affected sources of food is seafood, mainly due to the discharge of sewage along the coast. As a result, many kinds of heavy metals deposited in fish, shrimps, crabs and oysters are taken by people. All these are hidden threats to people’s health. The alarming problem of food contamination makes people recall the old time when there was no pollution.
To sum up, although the constantly improving of living standards may convince us that we have better food today than in the past, there are in fact new concerns on food quality: less nutrition but more pollution.
