Write an essay of about 100 - 150 words on the given topic. HEALTHY SOILS ARE FULL OF LIFE
Answers
Answer:
is caused by the reckless attitude of man towards nature. Our Earth provides us with food and shelter, whereas we treat it mercilessly and plunder its resources. Pollution is a direct result of our greed. We dump waste into our water bodies without caring for the organisms living in them. The balance of various gases in the atmosphere has been disrupted because of the large number of vehicles plying on the road. Even factories that release harmful gases into the atmosphere contribute to air pollution. When we do excessive and uncontrolled farming on a piece of land, it loses its natural minerals. So, when we use fertilizers to boost their productivity, it pollutes the soil. Noise pollution is caused by factories, jets, airplanes, etc. It harms our ears and can impair hearing.
Paragraph on Pollution – 200 Words for Classes 6, 7, and 8 Students
Pollution has rattled the natural order of our ecosystems and has brought heavy consequences to Earth’s inhabitants. The major reason for Pollution is the unchecked and illegal activities that misuse natural resources and don’t follow guidelines set by the pollution control boards across the country. Anything that causes Pollution is known as a pollutant. It can be a solid, liquid, or even gas. No matter what state the pollutant is in, it can have devastating effects on our natural ecosystem if it is left unchecked.
Water pollution forms a major category of Pollution and has become an urgent crisis in many countries. We cannot survive without water. So, when most of the water bodies will dry up or get chocked, the human population will come to an end. The next big form of Pollution is air pollution. It is mainly caused by toxic exhumes from vehicles and the burning of coal for electricity.
Soil pollution is witnessing an unexpected rise in recent times owing to the mass deforestation and illegal farming activities in tropical forests. Another significant yet largely ignored form of Pollution is noise pollution. The high decibel noises coming out from jets and airplanes contribute to noise pollution. It damages our eardrums and, in extreme cases, causes deafness.
Paragraph on Pollution – 250 to 300 Words for Classes 9, 10, 11, 12 and Competitive Exams Students
The natural mechanisms of the Earth that had been functioning in sync since the formation of the Earth are lying in disarray. This can be attributed to the exploitation of natural resources by humans. We, occupying the topmost strata on the ecological pyramid, should be conscious of the environment. Pollution has been a burning issue for the last 100 years, but little has been done to take steps towards rebuilding our ecosystem and saving it from the brink of collapse.
The Earth is in continuous motion; the principles of nature teach us that we must never disrupt the harmony of the various levels of the ecosystem. Meddling with natural processes can have disastrous long term effects that will push the entire Earth towards mass destruction. Pollutants must be identified and effectively dealt with to pull off a last saving grace for the sake of our co-habitants. It must be kept in mind that pollutants are not always toxic substances. Any unwanted substance that can disrupt the functioning of a natural system can be categorized as a pollutant.
Some pollutants don’t have any shape or size. For example, temperature rise in our atmosphere by a few degrees for a short time will not have any significant effect, but the same amount of rising in temperature in a water body will kill the thermo-sensitive organisms. Here, the temperature is a pollutant for the water body. There are certain invisible pollutants, too, like noise. Noise pollution wasn’t even recognized as a form of Pollution until the late 1970s. In 1972 it was recognized as a significant form of Pollution by the United States’ Pollution Control Board. Noise pollution is the trickiest to deal with, as it has no specific guidelines. Your neighbor partying in the middle of the night with stereos blasting music at a dangerously high level also falls under noise pollution. A deep sense of responsibility towards nature and empathy for all the organisms residing on Earth will go a long way in saving our planet from destruction.

This week’s blog post is written by Hannah, a 2nd year Monthly Blog Correspondent and Brookies, Bucktails, and Drummers alumni. Her role as a Conservation Ambassador led her to a new topic, soil conservation. After further investigation, Hannah is now well versed in soil conservation and lays out her research on why healthy soil is full of life in today’s blog.
As a Conservation Ambassador for the Wildlife Leadership Academy, it has been my pleasure to study various species and the efforts related to conserving each. Recently the opportunity presented itself for me to delve into something I wasn’t as versed in: soil conservation. Healthy soils hold a large percentage of life. Just one- acre sample, containing the top six inches of soil, can have more than 5,000 pounds of life in it. It has the most diverse variety of microscopic and macroscopic life on the planet. Most of the soil mass is made up of microorganisms (microbes) such as yeasts, algae, protozoa, bacteria, nematodes and fungi. Without having these important microbes, we would not have dark, rich, stable humus. Humus is organic matter that is made from the decomposing leaves and other plants by the microbes. The microbes use the soil as their food and shelter. This allows the soil to build and have a strong structure. (“Healthy Soils Are Full of Life- Natural Resources Conservation Service,”) Microbes are the foundation of a diverse ecosystem that provides a base for agricultural activity and sustainability.
Soil health, also referred to as soil quality, is defined as the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans (“Soil Health- National Resources Conservation Service- Soil,”). Soil quality should not be limited to soil productivity alone, but should encompass environmental quality, human and animal health, and food safety and quality (“American Journal of Alternative Agriculture,” V.7, Issue 1-2, 1992). In order to have healthy soil the proper balance and blend must occur of these three properties: biological, physical, and chemical. Biological healthy soil contains a variety of microbes that help to break down the organic matter (leaves, plants), convert nitrogen to organic forms that nurtures the crops, synthesize vitamins, enzymes, and hormones, and control the amount of soil-borne pathogens/parasitic nematodes. Physically healthy soil is based off of how compact the soil is, the storability of water, and its drainage ability. By tilling the fields, the water can be stored for later use, there is increased development of root systems, reduced runoff, and prevention of soil compacting. Aeration is another huge necessity for healthy soil because it allows the soil to breathe. This allows the crops to adapt to the wet and dry conditions. Chemically healthy soil balances the pH, salt, and nutrient levels. In order to have ideal crop growing conditions, there must be controlled and managed nutrients. Having too much nitrogen and phosphorus nutrients can be harmful to our environment. High levels of these elements can pollute the surface and the groundwater (“Healthy Soils Produce Healthy Crops-SARE,” 2012). Together these three properties work side by side to ensure healthy soil for crop production. Without one, the others cannot function properly and can result in soil degradation.
Soil quality, in agricultural land, is concerned with maintaining food and fiber production over large areas of space for an extended period of time (“Developments in Soil Science,” V. 25, 1997). The practice of converting natural vegetation to farm land increases the degradation process of the soil. More than 38% of the world’s natural habitat has already been converted to farming fields and pastures. The loose soil pollutes the streams and rivers, leading to a decrease in fish and other species. The degraded soil can no longer hold onto water, which allows for increased likelihood of flooding. In order to farm successfully, farmers must take care of the soil by tilling and rotating their crops year round (“Soil Erosion and Degradation-WWF,” 2017). Each crop provides a different nutrient that benefits the soil and provides biodiversity. By rotating crops, soil health and quality is maintained by replenishing the needed nutrients back into the soil.
