b. Bảo vệ môi trường: Nó quan trọng như thế nào?
c. Các giải pháp môi trường: Chúng thực tế như thế nào?
Môi trường chúng ta sống đang phải đối mặt với nhiều vấn đề nghiêm trọng. Chúng ta cần nhận thức rõ những vấn đề này để có thể tìm cách bảo vệ thiên nhiên.
A. Sự nóng lên toàn cầu là sự gia tăng nhiệt độ trung bình của khí quyển trái đất. Đó là một trong những vấn đề lớn nhất mà con người phải đối mặt ngày nay. Nó có thể gây ra những hậu quả nghiêm trọng như mực nước biển dâng cao, băng tan ở hai cực và các hiện tượng thời tiết khắc nghiệt như lũ lụt hoặc sóng nhiệt.
B. Một vấn đề môi trường khác là chặt phá rừng tự nhiên. Việc mất rừng có thể có tác động tiêu cực đến môi trường. Nó có thể làm hư hại môi trường sống tự nhiên của nhiều loài động vật và khiến động vật hoang dã gặp nguy hiểm. Nó cũng có thể phá hủy đất tự nhiên và dẫn đến biến đổi khí hậu.
C. Ô nhiễm không khí cũng là một vấn đề nghiêm trọng. Nguyên nhân chủ yếu là do khí thải từ xe cộ, máy móc hoặc nhà máy. Khi những khí độc hại này kết hợp với nước trong không khí, chúng sẽ tạo thành mưa hoặc tuyết, có thể gây hại cho mọi dạng sống. Ngoài ra, vấn đề này còn dẫn đến hiện tượng nóng lên toàn cầu và biến đổi khí hậu. Nó cũng là nguyên nhân chính gây ra các bệnh về đường hô hấp hay thậm chí là ung thư phổi.
D. Trên khắp thế giới, số lượng các loài động vật có nguy cơ tuyệt chủng đang tăng lên. Nhiều con trong số chúng biến mất vì ô nhiễm và biến đổi khí hậu. Ngoài ra, còn vì con người săn bắt và giết động vật một cách bất hợp pháp và đánh bắt quá nhiều cá cùng một lúc. Điều này đang làm đảo lộn sự cân bằng tự nhiên của các hệ sinh thái, có thể gây hại cho tất cả các sinh vật sống và không sống.
