Pollution, climate changes, over-exploitation by humans etc. are responsible for changes in the ecosystem. Change in an ecosystem is responsible for depletion in biodiversity which directly or indirectly affects human beings and their surroundings. So it is important to conserve biodiversity. There are various methods like in-situ conservation, ex situ conservation by which we can conserve our biodiversity.

Biodiversity Hotspots
Biodiversity hotspots are regions that contain a high level of biodiversity but are also under threat due to human activities. These areas are considered to be of great importance for the conservation of global biodiversity. The identification of biodiversity hotspots helps in prioritizing conservation efforts and resources.
Number of Biodiversity Hotspots
There are a total of 34 biodiversity hotspots identified globally. These hotspots are spread across different regions of the world and are characterized by a high number of endemic plant species and significant habitat loss.
Significance of Biodiversity Hotspots
Biodiversity hotspots are crucial for the overall health and functioning of ecosystems. They provide various ecosystem services such as pollination, nutrient cycling, and climate regulation. Additionally, these regions are often home to indigenous communities who have a deep understanding of the local biodiversity and its sustainable use.
Threats to Biodiversity Hotspots
Biodiversity hotspots face numerous threats, mainly caused by human activities. Some of the major threats include:
1. Habitat Loss and Fragmentation: The conversion of natural habitats for agriculture, urbanization, and industrial activities leads to the loss of critical habitats and disrupts ecological connectivity.
2. Climate Change: Rising temperatures, extreme weather events, and changes in precipitation patterns pose significant challenges to the survival of many species within the hotspots.
3. Pollution: Pollution from various sources, such as industrial discharges, agricultural runoff, and air pollution, can have detrimental effects on both terrestrial and aquatic ecosystems.
4. Over-exploitation: Unsustainable hunting, fishing, and logging practices can deplete populations of endangered species and disrupt the delicate balance of ecosystems.
Conservation Efforts
To conserve biodiversity hotspots and prevent further loss of species, various conservation methods are employed:
1. In-situ Conservation: This approach focuses on the protection and management of ecosystems within their natural habitats. It involves the establishment of protected areas, national parks, and wildlife sanctuaries to safeguard biodiversity.
2. Ex-situ Conservation: This method involves the preservation of species outside their natural habitats, often in specialized facilities such as botanical gardens, zoos, and seed banks. It helps protect endangered species and provides a safeguard against extinction.
3. Sustainable Development: Promoting sustainable practices, such as responsible land use, sustainable agriculture, and eco-tourism, can help reduce the pressure on biodiversity hotspots while supporting local communities.
4. Awareness and Education: Creating awareness among local communities, policymakers, and the general public about the importance of biodiversity conservation and its linkages to human well-being is crucial for long-term conservation efforts.
Overall, the identification and conservation of biodiversity hotspots play a vital role in preserving global biodiversity, protecting ecosystems, and ensuring the sustainable use of natural resources.
