Major causes of extinction of different species includesOptions :Habitat loss and over-huntingClimate change and pollutionDeforestationAll options are correct

To understand the major causes of extinction of different species, let's analyze the options provided:

1. Habitat Loss and Over-Hunting: Habitat destruction due to urban development, agriculture, and other human activities removes the natural environments that species depend on for survival. Over-hunting further reduces populations to unsustainable levels, directly impacting species survival.

2. Climate Change and Pollution: Climate change alters weather patterns, temperatures, and sea levels, which can make habitats inhospitable for native species. Additionally, pollution can poison ecosystems, affecting both terrestrial and aquatic life.

3. Deforestation: The clearing of forests for agriculture, urban development, and logging contributes significantly to the loss of biodiversity. Many species are dependent on forest ecosystems, and deforestation not only reduces available habitat but also fragments populations.

4. All Options Are Correct: Given that each of the previous points illustrates a legitimate and significant cause of extinction, this option acknowledges that extinction is a multifaceted issue resulting from the interaction of various environmental stresses.

Conclusion

Considering the cumulative effect of all these factors, the correct answer is All options are correct. Each of these issues plays a critical role in the decline of species, making it essential to address them collectively to mitigate extinction risks.
