Mỗi ngày trên đài phát thanh, trên TV và trên các tờ báo, chúng ta nghe, nhìn hoặc đọc về nhiều vấn đề trên thế giới, ví dụ, các vấn đề ô nhiễm. Ô nhiễm không khí là loại đầu tiên. Nó chủ yếu đến từ khói thải ra từ xe máy, ô tô, máy bay, tàu hỏa và khí độc phát ra từ các nhà máy. Ngoài ra, chất thải được đổ ở bất cứ đâu, ngay cả trong thành phố nơi có nhiều người sinh sống. Vấn đề ô nhiễm thứ hai là ô nhiễm biển. Nhiều người kiếm sống bằng nghề đánh bắt cá trên biển và con cá họ bắt được cho nhiều người ăn. Nhưng biển đã trở nên ô nhiễm từ sự cố tràn dầu và chất thải nhà máy đến nỗi cá đang chết dần. Ô nhiễm này không chỉ giết chết cá mà còn ảnh hưởng đến những người ăn cá. Ít khi bạn tìm thấy một nơi không bị ô nhiễm. Vấn đề này đang trở nên khó khăn hơn mỗi ngày. Chúng ta phải tìm một giải pháp tốt làm cho thế giới trở thành một nơi tốt hơn để sống
