Dưới đây là một bài nói mẫu cho chủ đề "Những điều bạn nên và không nên làm để sống xanh": Ladies and Gentlemen, Living green is not just a trend, it's a necessity. It's about making our planet a better place for future generations. But how can we live green? What should we do and what shouldn't we do? Firstly, let's talk about what we should do. We should reduce, reuse, and recycle. Reduce the amount of waste we produce by choosing products with less packaging and using reusable bags, bottles, and containers. Reuse items as much as possible before throwing them away. Recycle paper, plastic, glass, and metal to decrease the amount of waste that goes into landfills. We should also conserve energy. Turn off lights, computers, and electronic devices when they're not in use. Use energy-efficient appliances and light bulbs. And consider alternative energy sources like solar or wind power. Furthermore, we should eat locally and organically. Local food doesn't have to travel as far, reducing carbon emissions. Organic farming is better for the soil, the water, and the creatures that inhabit them. Now, let's move on to what we shouldn't do. We shouldn't waste water. Don't leave the tap running while brushing your teeth or washing dishes. Fix leaks promptly. And consider installing low-flow showerheads and toilets. We shouldn't drive unnecessarily. Walk, bike, carpool, or use public transportation whenever possible. If you must drive, make sure your vehicle is well-maintained to get the best fuel efficiency. And finally, we shouldn't support companies that harm the environment. Do your research and choose to buy from businesses that are committed to sustainability. In conclusion, living green is about making conscious choices every day. It's about thinking of the big picture and realizing that our actions have an impact on the world around us. So let's all do our part to live green and make our planet a healthier, happier place. Thank you.
