Answer (1)
Answer:1. Why is it important to classify waste based on its properties and effects?Classifying waste based on its properties and effects helps us manage and dispose of it properly. It prevents harm to the environment and human health by identifying hazardous and non-hazardous waste. It also allows recycling and composting efforts to be more efficient and reduces pollution.2. What could happen if hazardous waste is not disposed of properly?If hazardous waste is not disposed of properly, it can contaminate soil, water, and air, leading to serious environmental damage. It can also pose health risks, such as poisoning, respiratory problems, and diseases for humans and animals.3. Give two examples of biodegradable waste and explain how they decompose:Example 1: Fruit peels – They decompose naturally through the action of microorganisms like bacteria and fungi, breaking down into organic matter and turning into compost that enriches the soil.Example 2: Vegetable scraps – These also break down through microbial activity, transforming into nutrients that help plants grow, completing the natural cycle of decomposition.4. Suggest one way to reduce non-biodegradable waste in daily life:One effective way to reduce non-biodegradable waste is to use reusable items like cloth bags, stainless steel water bottles, and glass containers instead of single-use plastics. This reduces plastic pollution and helps minimize waste production.
