How can you help in reducing the problem of waste disposal? Give any two methods.
We can help in reducing the problem of waste disposal by adopting the following two methods:
First, we can segregate biodegradable and non-biodegradable wastes at home and ensure they are treated separately. This helps in proper disposal and prevents environmental pollution. Biodegradable waste like kitchen waste (vegetable peels, spoilt food, used tea leaves) can be separated from non-biodegradable items.
Second, we can practice composting by burying biodegradable waste in a pit in the garden or in a bucket covered with soil. Materials like kitchen waste change their form and structure over time and get decomposed naturally. This reduces the amount of waste that needs to be disposed of otherwise.
Explanation
The textbook context from Activity 13.7 emphasizes the importance of having mechanisms to treat biodegradable and non-biodegradable wastes separately. Activity 13.5 demonstrates how biodegradable waste like kitchen waste (spoilt food, vegetable peels, used tea leaves) can be buried in a pit and observed to change form over time, which is essentially composting. Both activities directly address methods students can implement to reduce waste disposal problems.
