Sample Environmental Essay: How Can Food Security Be Achieved?
Food security basically assures the continuation of access to food, regardless of race or class, at all times for the sake of a healthy life. The number of people that die from starvation, dietary deficiencies or malnutrition throughout the world sits at a staggering 18 million. The earth has a limited amount of food and if this pattern of insufficient food production continues, we’re looking at a growing population with pressing needs and the possibility of riots and anarchy spreading uncontrollably.
Population growth needs to be kept in check if food security is to be achieved. Other factors tying into food security include the availability of water, active farming, equal distribution and reasonable consumption of food. It is very important that small scale farmers are properly incentivized so that the culture of farming continues to thrive. The international community also needs to come together to ease trade related restrictions.
Long term food security can be achieved through protecting and conserving wild crop variants in wildlife sanctuaries and national parks. According to a study if conservation isn’t taken seriously, by the year 2025 around 60,000 plant species will go extinct, which accounts for roughly 25% of the world’s crops.
Environmental scientists are currently working on a second green revolution so that food security is assured for the future. According to scientists, this new revolution should be based on proper water management, equity, biodiversity, conservation of cultivars, environmental sensitivity and complete protection of wild crops.
It is very important that farming methods are revised. Chemical agriculture is harmful to the environment and it is crucial for the sake of long term food security that a shift is made to organic farming through the practice of integrated nutrient management and pest management. Not only that but urban settings can also be utilized to grow vegetables and fruits by using waste household water and fertilizer.
The land’s degradation and desertification needs to be stopped and water pollution needs to be reversed. Similarly, the soil needs to go through an expansive conservation processes relative to current farming methodologies. It needs to be enhanced using organic matter, management of watersheds and rotation of crops at a very micro level. This is the only way to achieve agricultural production needs.
Population control is also a major requirement in order to keep the food supply effective. A large number of newly born babies go through malnutrition; the literacy rate should be improved in the female population particularly, so that they understand what nutrition their newborns need.
Overall, the need for awareness towards the management of food has become very important as a lot of food goes to waste simply due to negligence.

Environmental pollution essays are narrative essays that are based on experiences in our daily lives. These essays begin with general statements and reflections on the meaning of the topic and the importance of narrative such essays. The bodies and conclusions that are described in engaging ways with up to date statistical information on pollution which makes the reader always alert and fully invited and feel to be part of the story.
How to start
The environmental pollution essays henceforth may take the form of description of different types of pollution such as sound, water, air and soil among others. Therefore, the body describes the various types of environmental contamination in each paragraph. On a separate note, the essays might outline the consequences of pollution such as global warming, extinction of resources, health hazards on people and animals, and demolition of the ecosystem where by individual paragraphs describe agricultural activities, transportation, technology and industry, residences of people and their behaviors among others. At the introduction, there is usually a brief description of the terms such as environment and pollution followed by different types of pollution exhibited on the environment or the various consequences of pollution. These form the thesis statements that are elaborated in the subsequent sections.
Example of introduction for a pollution essay:
Man is the Main Polluter
“The term environment is referred to as the surrounding of the human being. Hence it includes air, plant, water, animal life, and non-living things among others. For the purpose of peaceful coexistence, man has to make sure that all these aspects of the environment are not tampered with and at all times effectively utilized and preserved for future generation. However, the current chaotic situation in the environment is a consequence of environmental pollution. Pollution is contamination of the natural environment by either human or natural actions without rectifying such activities to the extent that they become a health hazard to all the living things. In most cases, physical activities have been blamed for pollution such as earthquakes, cyclones, volcanic eruption, storms, rain and floods among others. However, man has been the greatest environmental polluter who has caused adverse impacts to him, others, plants, and animals. Thus, the essay describes man’s different activities that have caused environmental pollution.”
How to write the body
The body of the essay will delve into the various ways and activities that man engages in which lead to environmental pollution. Every activity is described in individual paragraphs where the first sentence denotes the point. This is followed by an elaboration of the point giving evidence to support the argument in a logical sequence. Furthermore, the writer joins all these statements interestingly using transitional words to ensure there is a flow so that the reader stays engaged. Each paragraph discusses a point separately though they are interconnected concerning the thesis statement regarding the topic.
Example of body paragraphs for an environmental pollution essay:
“One activity that man engages in is urbanization and population increase in an area. Therefore, the greatest activity that results is increased scatter of garbage and trash within his dwelling environment. Man dumps rubbish in every place that decay. However, most of this rubbish have toxic components that are released and permeate the soil to different water catchment areas such as rivers, oceans, seas, dams and boreholes. Furthermore, people directly throw garbage to these water areas which have formed special garbage islands, especially in oceans and seas. Sectors such as the Ganges River in Varanasi and Calcutta are highly polluted by waste which has bacteria hence have negatively impacted on the aquatic lives. People who live in such areas suffer from diseases such as cholera because they drink such raw water. Also, the garbage in such areas releases smell with the constant decay of materials which cause air pollution. Similarly, water is also polluted through industrial activities where items are processed or manufactured. The wastewater is channeled to rivers and seas in the locality. These waters are also contaminated with the highest levels which disrupt the aquatic life and the ecosystem such as the food chain.
Secondly, both the agriculture and the industrial sectors are activities responsible for water, air, soil and noise pollution. Man uses pesticides and fertilizers in his agricultural fields. These items have adverse effects on water, air, and soils. However, some factories that produce these chemicals have installed different water and air purification systems though such actions are minimal compared to industries existing in both developed and developing nations. Besides, many nations have not subscribed to global environmental protection programs due to the limitation of such activities in specific territories which further derails efforts to solve the universal problem.
Lastly, man is responsible for air pollution through factory emissions, burning of the fossil fuels, and transportation among others. The smoke emitted from such activities concentrates in the air that people breathe in. Consequently, this results in respiratory diseases, cancer, and vision problems among others. Also, dangerous gases are emitted in the air such as nitrogen oxides, carbon monoxide, chemical vapor and sulfur dioxide. The reaction of these gases combined with the cooling of the water vapor results in acid rains that corrode plants and other items on the earth surface. On the same note, the release of carbon dioxide into the atmosphere from the industries is responsible for its high concentration that causes a blanket of the atmosphere. This leads to global warming which alters the natural processes on the earth.”
How to conclude
The conclusion of environmental pollution essays entails summary of the points discussed in the body as well as a reiteration of the thesis statement. This is followed by a challenging remark that challenges the reader to reevaluate the remedies as the best solution and challenge his way of thinking regarding the topic.
Example of conclusion for a pollution essay:
“In conclusion, man is noted as the greatest polluter of the environment. This is pegged on its devastating activities such as extraction and processing of resources, increase in population that leads to damping and scatter of garbage, increases industrial activities among others. Consequently, such activities have resulted in pollution of air, water, soil, and sound. These activities have negatively impacted on environment hence their related impacts include disrupted ecosystem, destruction of aquatic life, disease, global warming and acid rains among others. However, man has realized that environmental pollution is a global phenomenon hence he has laid measures to curb the problem and has called for action of rehabilitation, protection, and conservation of the environment. However, challenges do occur due to the existence of such measures in specific regions which hinder willful joining of hands to solve the problems.”
