The correct answer is option A) 1, 2, and 3 only.
Explanation:
Biodiversity refers to the variety of living organisms present in a particular area, including plants, animals, and microorganisms. It is essential for the stability and functioning of ecosystems and provides numerous ecological services. However, various factors can threaten the biodiversity of a geographical area. Let's discuss the given options:
1. Global warming:
Global warming refers to the increase in average temperature of the Earth's atmosphere due to the accumulation of greenhouse gases. It can have significant impacts on biodiversity by altering the climate patterns, affecting the distribution and abundance of species, and causing changes in ecosystems. Rising temperatures can disrupt the natural habitats and life cycles of many organisms, leading to their decline or extinction.
2. Fragmentation of habitat:
Habitat fragmentation occurs when large continuous habitats are divided into smaller and isolated patches. This can be caused by human activities such as deforestation, urbanization, and infrastructure development. Fragmentation can disrupt the natural movements and interactions of species, restrict their access to resources, and increase their vulnerability to predation and other threats. It can also lead to genetic isolation and reduced biodiversity within fragmented habitats.
3. Invasion of alien species:
Alien species, also known as invasive or exotic species, are non-native organisms that are introduced to a new environment. They can outcompete native species, disrupt ecological relationships, and alter ecosystem processes. Invasive species can spread rapidly and cause significant harm to local biodiversity by preying on native species, displacing them from their habitats, or introducing diseases and parasites. They can also disrupt the functioning of ecosystems and reduce overall biodiversity.
4. Promotion of vegetarianism:
While promoting vegetarianism can have various environmental and ethical benefits, it is not directly related to threats to biodiversity. Vegetarianism primarily focuses on reducing the consumption of animal products for health, environmental, and ethical reasons. While it can indirectly contribute to biodiversity conservation by reducing the demand for animal agriculture and its associated habitat destruction, it is not a direct threat to biodiversity.
In conclusion, global warming, fragmentation of habitat, and invasion of alien species are significant threats to the biodiversity of a geographical area. Therefore, the correct answer is option A) 1, 2, and 3 only.

Option (a) is the correct answer. Global warming is one of the biggest threats to biodiversity of an area. Climate change will increase the probability of extreme weather phenomenas and thus pose a threat to biodiversity.
Fragmentation of habitat either due to natural causes (floods, fires, droughts, earthquakes) or man made (roads, construction, settlement, pollution) is also a major threat to biodiversity.
Invasive alien species take over the ecosystem and compete with the indigenous species for resources thus posing a threat to biodiversity. Promotion of Vegetation does not pose a threat to biodiversity, on the other hand it might help reduce the stress on ecosystems and biodiversity.
