We should dispose of waste properly by throwing it into the trash bins.
Throwing garbage into the trash bins is essential for maintaining cleanliness and hygiene in our surroundings. Littering is an uncivilized act that can have negative impacts on the environment. To protect the environment, it is crucial to dispose of waste in designated trash bins.
It is important not to litter as it contributes to the beauty of our cities. If waste is carelessly discarded, it can lead to pollution and create an unpleasant odor. Therefore, we must ensure that waste is thrown into trash bins to maintain a clean and healthy environment, both at home and in public places.
Trash bins play a significant role in urban sanitation and environmental protection. They serve as a storage location for waste and also act as the starting point for initial waste sorting, which is beneficial for recycling and reuse. Many places implement a "four-color classification" system for domestic waste, which requires placing four different bins for each type of waste, making it convenient for people to sort waste properly.
Do not underestimate the importance of these bins, as they are the fundamental hardware for effective waste sorting. The significance of recycling waste includes:
1. Reducing land occupation: Some substances in household waste are non-biodegradable, leading to severe soil erosion. Waste sorting can reduce the volume of waste by over 50%, thereby saving land resources.
2. Minimizing environmental pollution: Discarded batteries contain toxic substances like mercury and cadmium, which can harm humans. Plastic waste in soil can reduce crop yields, and animals dying due to ingesting plastic is a common occurrence. Recycling helps mitigate these hazards.
3. Turning waste into treasure: China annually uses 4 billion plastic takeout boxes and 500-700 million instant noodle bowls, amounting to 4-7% of municipal waste. One ton of recycled plastic can produce 600 kg of diesel. Recycling 1.5 million tons of paper can save the logging of 1.2 million tons of wood needed to produce that amount. About 30-40% of domestic waste can be recycled, making it a cost-effective resource that should not be wasted.
