The species of an organism lasting with the change in suitable condition of survival with the time. Such species are called critically endangered.

Introduction:
Species at high risk of extinction in the future are called critically endangered. This means that their population has declined significantly, and they face an extremely high risk of becoming extinct in the wild. The conservation of critically endangered species is crucial to maintain biodiversity and ensure the well-being of ecosystems and human beings.

Explanation:
1. Definition of critically endangered species:
Critically endangered species are those that are facing an extremely high risk of extinction in the near future. Their population has declined drastically, and they are on the brink of disappearing from the wild.

2. Factors leading to critically endangered status:
Several factors contribute to the critically endangered status of a species. These may include:
- Habitat destruction: Loss or degradation of natural habitats due to human activities such as deforestation, urbanization, and pollution.
- Climate change: Alteration of temperature and precipitation patterns, leading to shifts in ecosystems and affecting the survival of many species.
- Over-exploitation: Unsustainable hunting, fishing, and harvesting practices that result in the depletion of species populations.
- Pollution: Contamination of air, water, and soil with toxic substances, which can have detrimental effects on organisms.
- Invasive species: Introduction of non-native species into an ecosystem, which can outcompete and displace native species.
- Disease outbreaks: The spread of diseases, often facilitated by human activities, can have devastating impacts on species populations.

3. Importance of conserving critically endangered species:
Conserving critically endangered species is crucial for several reasons:
- Biodiversity preservation: Every species plays a role in maintaining the balance and functioning of ecosystems. Losing a species can have cascading effects on the entire ecosystem.
- Ecological services: Many species provide important services such as pollination, seed dispersal, and pest control, which are essential for the well-being of ecosystems and human beings.
- Medicinal and genetic resources: Critically endangered species may possess unique genetic traits or produce compounds that can be used for medical purposes. Losing these species means losing potential benefits for human health and well-being.
- Ethical responsibility: As stewards of the planet, it is our responsibility to protect and preserve the diversity of life forms on Earth.

4. Conservation methods:
To conserve critically endangered species, various methods can be employed:
- In-situ conservation: This involves protecting species within their natural habitats, such as establishing protected areas, national parks, and wildlife sanctuaries.
- Ex-situ conservation: This refers to conservation efforts outside of the natural habitat, such as captive breeding programs, botanical gardens, and seed banks.
- Habitat restoration: Efforts to restore and rehabilitate degraded habitats to provide suitable conditions for species survival.
- Sustainable resource management: Implementing sustainable practices in industries such as forestry, fishing, and agriculture to minimize the negative impacts on species populations.
- Public awareness and education: Raising awareness about the importance of biodiversity conservation and promoting responsible behavior among individuals and communities.

Conclusion:
Conserving critically endangered species is of utmost importance to maintain biodiversity, ensure ecosystem stability, and secure the well-being of human beings and their surroundings. By implementing various conservation methods, we can take a step towards protecting these species from extinction and preserving the rich tapestry of life on our planet.
