Give any two ways in which biodegradable substances would affect the environment

Question 2 Biodegradable substances affect the environment in the following ways: → The biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance the soil fertility. → The biodegradable substances mainly contain carbon. These substances after decomposition release that carbon back into the atmosphere. The influx of carbon into the atmosphere and its corresponding oxide formation amplifies global warming hence brings in undesirable climatic change.

We generate a massive amount of solid waste. To be exact, during 2018, the United States generated 292.4 million tons of solid waste. If you ask me – that’s way too much waste. We can reduce this excess amount of solid waste by using biodegradable substances. Unlike non-biodegradable solid waste, biodegradable substances decompose in a short amount of time. When compared to non-biodegradable materials, biodegradable substances are the better choice. But how do biodegradable substances affect the environment? • • • • • • • • • • What is the Meaning of Biodegradable Waste? Biodegradable waste is a substance that is decomposed by living organisms. Bacteria, fungi, and environmental conditions cause the decomposing of the biodegradable waste. When biodegradable waste decomposes, there are fewer toxins entering the environment. And some biodegradable waste turns into compost. For instance, food waste becomes compost. Damaging Effects of Biodegradable Waste I say, in most circumstances, biodegradable substances are better than non-biodegradable materials. I recognize the benefits of biodegradable substances. I also know it is important to examine the drawbacks of biodegradable waste. In large quantities, biodegradable waste can damage the environment and harm human health. In landfills, these piles are a mixture of solid waste and biodegradable waste. When in large piles, the biodegradable substances get trapped underneath other debris. This cuts off the oxygen supply. And that ...

Hint: “Biodegradable” refers to the ability of things to get disintegrated (decomposed) by the action of microorganisms such as bacteria or fungi biological (with or without oxygen) while getting assimilated into the natural environment. Complete Answer: Biodegradable substances affect the environment in the following ways: (i) Biodegradable substances are decomposed by the action of microorganisms and decomposed materials are recycled through a geo-chemical cycle. (ii) Biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance soil fertility. (iii) These substances keep the environment clean. (iv) They may produce foul smell during the decomposition process. (v) Waste decomposing in landfills produces harmful methane, a gas that’s 100-120 times more powerful than carbon dioxide at the time of emission. Note: All the wastes produced by humans, animal waste, plant products, dried leaves, grass, fruits, flowers, food wastes, wood and other remains of the death of living creatures are grouped into Biodegradable substances. These can be used for the generation of energy through biogas or compost.

Explanation Various roles played by decomposers in the ecosystem are: → They decompose biodegradable substances into useful substances. → They release nutrients into the soil by decomposing dead and decaying matter, thus making the soil fertile. → They maintain the nutrient pool by returning back the nutrients in the pool. Biodegradable substances affect the environment in the following ways: → → Biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after...

Non-biodegradable substances: • These are called non-biodegradable because they cannot be decomposed by natural biological processes such as the decomposition by microorganisms. • These substances persist for a long time in the environment due to this ability. Effects of non-biodegradable substances on the environment: • The non-biodegradable substances remain in the non-degraded form for a long time in the environment and thus cause pollution. • They can enter the food chain in different ways. For example, they can enter the plant tissue through the soil or contaminated water. • The presence of these substances can affect the physical environment by reducing the fertility of the soil as well. Methods of safe disposal of non-biodegradable substances: • Recycling is one of the ways to safely dispose non-biodegradable substances. • Landfill is another option, where the non-biodegradable substances are dumped in a low-lying region and covered with soil.
