Sắp xếp các câu để tạo thành một đoạn văn có ý nghĩa:

1. **e**. It is important to protect our heritage (di sản) for several reasons.
2. **b**. Firstly, our heritage represents (đại diện) our history and our culture. It tells the story of who we are as a belonging (cảm giá rằng thuộc về chúng ta) and helps to preserve our identity (bảo tồn bản sắc) and our sense of community (cảm giác về cộng đồng).
3. **c**. Thirdly, heritage tourism is a major industry in many parts of the world. Preserving our heritage not only benefits our cultural identity (bản sắc văn hóa), but it can also bring economic benefits to local communities through tourism.
4. **a**. Secondly, heritage sites and artifacts (hiện vật) are often irreplaceable (không thể thay thế được). Once they are destroyed or lost, they cannot be recovered. Many heritage sites and artifacts are also fragile (dễ vỡ) and require careful preservation (bảo quản) to prevent deterioration (bị xuống cấp).
5. **d**. Finally, protecting our heritage is a moral obligation (nghĩa vụ đạo đức). We have a duty to safeguard our cultural heritage for future generations and to ensure (đảm bảo) that it is not lost or destroyed through neglect (bỏ bê) or willful (cố ý) destruction (phá hủy).

Tóm lại, thứ tự sắp xếp là: **e -> b -> c -> a -> d**.
