Now, I'm going to give a talk about environmental problems.
To begin with, environmental problems are one of the most serious issues of our time. As far as I know, people worry about environmental problems nowadays because they see how pollution, climate change, and deforestation affect our planet. Many people have noticed that the weather is changing, animals are disappearing, and the air in big cities is becoming less clean. Besides, people understand that these problems can harm their health and the future of their children.
Speaking about my region, the most serious environmental problem where I live is air pollution. In my town, there are many cars and factories, and during the winter, the air quality becomes quite poor. This makes it difficult to breathe, especially for older people and children. There is also a problem with waste, because not all residents separate their rubbish properly for recycling.
As for what young people can do, I believe we can contribute a lot to improving the ecological situation. For example, we can take part in clean-up events in parks and forests, plant trees, and recycle our waste. We can also save water and electricity at home, use reusable bags instead of plastic ones, and walk or cycle instead of using cars for short distances.
In conclusion, I'd like to say that I take environmental problems very seriously. I think that every person should care about the planet and do their best to protect nature. Even small actions can make a big difference if we all work together.
That's all I wanted to say about environmental problems.
