Which of the following is not a major threat to biodiversity?
- a. No-till agriculture
- b. Habitat destruction
- c. Invasive species
- d. Human-caused climate change
Introduction: Biodiversity is defined as the diversity of living organisms (plants, fungi, micro-organisms, animals) in the world or a specific habitat. Biodiversity is the result of natural processes, evolution, and human influence. It plays an important role in sustainable development and conservation of the natural environment.
Answer to Problem 1MC
Correct answer: Option b. “Habitat destruction”.
Explanation of Solution
Reason for the correct statement:
Option b. is given as, “Habitat destruction”. Biodiversity is facing threat because of humans. Humans can maintain biodiversity in several ways, by conserving and protecting the natural ecosystem such as protected areas, wildlife sanctuaries, biosphere reserves are specific areas for the protection of flora and fauna. Invasive species, no agriculture, and human-caused climate change are the major threats to biodiversity. Habitat destruction is a cause of threat to diversity but it is not a major threat.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as “No-till agriculture”. No-till agriculture is a major threat to biodiversity. Hence, Option a. is an incorrect answer.
Option c. is given as “Invasive species”. Invasive species is a major threat to biodiversity. Hence, Option c. is an incorrect answer.
Option d. is given as “sustainable agriculture”. Sustainable agriculture is a major threat to biodiversity. Hence, Option d. is an incorrect answer.
Hence, options a., c., and d. are incorrect.
Habitat destruction is not a major threat to biodiversity.
