Topic: Talking about human activities and global warming
Sample:
Hello teacher and everyone. My name is __. I’m a student in class 11. Today, I’m going to talk about other human activities that contribute to global warming.
First, industrial activities are one of the main causes of global warming. Many factories release large amounts of greenhouse gases such as carbon dioxide from burning fossil fuels. These gases trap heat in the atmosphere and make the Earth warmer.
Second, transportation also contributes greatly to global warming. Cars, buses, ships, and airplanes burn gasoline, diesel, and other fuels. As a result, they release a lot of carbon dioxide into the air. The increasing number of vehicles causes more pollution and climate change.
Agricultural practices also affect the environment. The overuse of chemical fertilizers releases harmful gases into the atmosphere. Besides that, rice farming and raising animals can produce methane gas.
To reduce global warming, we should save energy, use public transportation, recycle waste, plant more trees, and use eco-friendly products.
In conclusion, many human activities increase greenhouse gases and cause global warming. Everyone should work together to protect the environment and make the Earth a better place for future generations.
Thank you for listening.
