What are the positive and negative effects of agriculture on ecosystem and positive effects of population growth on agriculture and negative role of microorganisms?
Agriculture affects the environment a lot, both positively and negatively. It can lead to soil erosion, water pollution; contribute to climate change, and deforestation. It can also help reduce CO2 levels, improve air quality, habitat for wildlife, and provide food. Bacteria improve the soil so that new plants can become established. Without bacteria, new plant populations and communities struggle to survive or even exist. Bacteria change the soil environment so that certain plant species can exist and proliferate. Most types of bacteria aren't harmful; many are even helpful. They make up your microbiome, which keeps your gut healthy. Other bacteria, called pathogens, can cause infections that require treatment. Healthcare providers can prescribe antibiotics to treat many of these infections. As population grows, the demand for food also raises as a result the price of agricultural outputs increase. In theory, either an increase in the price of provisions would arise from an increase of population faster than the means of subsistence, or from a different distribution of the money of the society.Microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms. Pathogenic microorganisms include fungi, oomycetes, bacteria and viruses. Some of these pathogenic microorganisms will decompose root nodules, leaching nutrients from the plant, reducing the efficiency of nutrient uptake and mobilisation, and further leading to nutrient deficiency and stunted plant growth. Runoff often carries pesticides from farmers' fields that can damage aquatic ecosystems. A handful of farm dirt is rich in biodiversity. Soil biodiversity includes animals, bacteria, fungi and even the roots of plants growing above. Soils form complex ecosystems that make farming possible.
Positive effects of agriculture on the ecosystem:
Negative effects of agriculture on the ecosystem:
Positive effects of population growth on agriculture:
Negative role of microorganisms in agriculture:
It's important to note that the effects of agriculture and population growth on the ecosystem are complex and interconnected and depend on a range of factors such as farming practices, land use, and climate.
I agree with Aloke Saha that microbes cause infectious diseases such as flu and measles. There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms. Pathogenic microorganisms include fungi, oomycetes, bacteria and viruses. Some of these pathogenic microorganisms will decompose root nodules, leaching nutrients from the plant, reducing the efficiency of nutrient uptake and mobilization, and further leading to nutrient deficiency and stunted plant growth. Microscopic creatures including bacteria, fungi and viruses can make you ill. But what you may not realize is that trillions of microbes are living in and on your body right now. Most don't harm you at all. In fact, they help you digest food, protect against infection and even maintain your reproductive health. The primary harmful effects of microbes upon our existence and civilization are that they are an important cause of disease in animals and crop plants, and they are agents of spoilage and decomposition of our foods, textiles and dwellings. Use of High yield varieties of seeds to increase production for increasing population will result in over irrigation, soil contamination, high pesticides usage and alkalinisation of lands. Population movements increase urban populations and reduce rural populations. This reduces labor productivity in agricultural areas and causes these areas to remain inactive, and increases the pressure of urban development on these areas. While negative impacts are serious, and can include pollution and degradation of soil, water, and air, agriculture can also positively impact the environment, for instance by trapping greenhouse gases within crops and soils, or mitigating flood risks through the adoption of certain farming practices. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
