While you read

Loài người chỉ là một loài nhỏ trong thế giới sinh vật. Nhiều loài khác tồn tại trên hành tinh này. Tuy nhiên, con người có ảnh hưởng lớn đến phần còn lại của thế giới. Họ đang thay đổi môi trường bằng cách xây dựng thành phố và làng mạc ở nơi trước kia từng là rừng. Họ đang ảnh hưởng đến nguồn cung cấp nước bằng cách sử dụng nước cho công nghiệp và nông nghiệp. Họ đang thay đổi tình trạng thời tiết bằng việc chặt cây cối trong các khu rừng. Và họ đang phá hủy không khí bằng cách thải các chất gây ô nhiễm vào không khí.

Có thể nói rằng con người thay đổi môi trường trên mọi phương diện thông qua các hành động của họ và thói quen của họ. Điều này đã dẫn đến hai hậu quả nghiêm trọng. Đầu tiên là nhiều loài động vật quý hiếm bị giết. Thứ hai là môi trường nơi mà các loài động vật đang sinh sống bị phá hủy nặng. Kết quá là, số lượng các loài động vật quý hiếm đang giảm rất nhanh chóng, chúng đang có nguy cơ bị tuyệt chủng.

Để đảm bảo rằng các loài động vật quý hiếm này không biến mất, những nỗ lực đã được thực hiện để bảo vệ môi trường mà chúng đang sống. Các nhà khoa học đã lập danh sách các loài có nguy cơ tuyệt chủng và dề nghị cách để cứu chúng. Nhiều tổ chức đã được thành lập và nhiều quỹ được xây dựng. Hàng ngàn các công viên quốc gia trên toàn thế giới đã được thiết lập để bảo vệ động vật có nguy cơ tuyệt chủng. Luật pháp được đưa ra để cấm việc giết hại động vật có nguy cơ tuyệt chủng và sự tàn phá của môi trường nơi chúng sinh sống.

Nếu sự can thiệp của người dân với môi trường giảm, nhiều loài sẽ sống sót và sinh sản nhiều hơn. Trái đất sẽ là một hành tinh hạnh phúc nơi con người động vật và thực vật cùng chung sống một cách hòa bình.
