2. Soon we will use up all the coal in the world, and there won't be any left. Coal is a non-renewable energy source, which means that it takes millions of years to form and cannot be replenished within a human lifespan. As we continue to consume coal for energy and other purposes, we deplete the finite reserves, which will eventually lead to its complete exhaustion.
3. Some types of bird are dying out. This means that certain species of birds are becoming extinct or disappearing from the world. There are several reasons for this, including habitat loss, pollution, climate change, and human activities such as hunting.
4. People mustn't cut down trees because it destroys the world's forests. Trees play a crucial role in the environment by providing oxygen, storing carbon, and supporting biodiversity. When trees are cut down, it can lead to deforestation, which has numerous negative impacts such as loss of habitat for animals, soil erosion, and increased greenhouse gas emissions.
5. I don't want to live in a big city because there's too much pollution. Cities, especially large ones, tend to have high levels of pollution due to factors like vehicle emissions, industrial activities, and population density. This pollution can have detrimental effects on both human health and the environment, including respiratory problems, reduced air quality, and negative impacts on ecosystems.
