In recent years, pollution has become a serious problem in many countries. Factories release harmful gases into the air, and plastic waste is polluting the oceans. To protect the environment, people are encouraged to recycle, reduce waste, and use less electricity. Some countries have started using renewable energy sources, such as solar and wind power, instead of coal and oil. Scientists warn that if we do not take action now, the damage to the Earth may become irreversible. It is important for everyone to do their part to protect our planet.
