I'll choose topic 2. Here's my response: Global warming is a pressing issue that affects us all. There are several human activities that contribute to this problem. Today, I'd like to talk about three of them. Firstly, the burning of fossil fuels is a major contributor to global warming. The increasing demand for energy has led to a rise in the consumption of coal, oil, and gas. When these fossil fuels are burned, they release carbon dioxide and other greenhouse gases into the atmosphere, trapping heat and causing the Earth's temperature to rise. Secondly, deforestation and land-use changes are also significant contributors to global warming. Trees absorb carbon dioxide during photosynthesis, but when forests are cut down or cleared for agriculture and urbanization, this carbon is released into the atmosphere. Furthermore, trees provide oxygen and help regulate the climate, so losing them exacerbates the problem. Lastly, the production and transportation of goods are another significant source of greenhouse gas emissions. The global supply chain relies heavily on air and sea transport, which burns fossil fuels and releases emissions. Additionally, the manufacturing process itself often requires energy and generates waste, contributing to the problem. In conclusion, these three human activities – the burning of fossil fuels, deforestation and land-use changes, and the production and transportation of goods – are significant contributors to global warming. It's essential for us to be aware of these issues and take steps to reduce our carbon footprint and mitigate the effects of climate change.
