Answer: Because currently the type of human food and the way it is produced, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.
Step-by-step explanation:
Humans need to eat a varied and balanced diet, so a correct diet must contain adequate amounts of proteins, lipids, carbohydrates, vitamins and minerals. In addition, it is necessary to take into account the need for drinking water. However, the modern diet is often unbalanced, unstructured and is often associated with an increasingly sedentary lifestyle.
Human activities to produce food are carried out through land clearing, tillage and the introduction of new plant and animal species, and their effects depend on the extent and frequency of exploitation. An example is the elimination of native vegetation or the passage of heavy machinery, in order to use these lands to raise farm animals that will eventually produce meat and milk for consumption but at the cost of damaging forests. Reducing the amount of forests and vegetation has severe consequences in terms of climate change and the further increase of torrential rains and floods. So, this is an example where increased production of one type of food produces severe damage to the environment. In addition, the main source of contamination is found in the wastewater from slaughterhouses, which includes feces and urine, blood, lint, laundering and residues of meat and fat from carcasses.
In some cases, population growth has led to intensified land use and increased productivity in areas already prepared for cultivation. In other cases, population growth has not been matched by increases in productivity, leading to an increase in land devoted to food production.
On the other hand, the high consumption of processed foods (candies, cookies, mayonnaise, etc.) is packaged in plastic containers that are highly pollutant. Therefore, moving away from a more natural food, makes us produce more garbage.
It is necessary to find ways to achieve a sustainable balance without giving up the fight against hunger and environmental protection. However, there are currently economic interests that influence the forms of production and the type of food the population eats. And the increase in the world's population means that arable land per inhabitant is constantly decreasing. The environmental impact that natural and human systems can tolerate has its limits.
There are also more and more farmers reducing the use of pesticides and fertilizers, but this production is limited in relation to total food production. There is evidence that these production strategies, in addition to being more environmentally beneficial, are economically viable for the market sectors they serve. However, most large-scale commercial producers find the intensive use of pesticides and mineral fertilizers economically profitable, and there has not been a general acceptance of environmentally friendly production technologies such as integrated pest management and integrated plant nutrition systems.
As a summary, currently the type of food we eat and the way we produce it, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.
