Immediate threats to conservation of biodiversity are well-known. They include: loss and degradation of habitat, climate change, chemical and biochemical pollution, logging and poaching, invasive species, disease, loss of plant pollinators, and many more.
What is the biggest challenge in preserving biodiversity?
The major threats to biodiversity that result from human activity are habitat destruction, habitat fragmentation, habitat degradation, overexploitation of species for human use, introduction of exotic species, and increased spread of diseases.
What are the challenges for the biodiversity conservation?
Loss and fragmentation of suitable natural habitats is the main threat to biodiver- sity conservation in Nepal. It is occurring at all levels including terrestrial and aquatic habitats.
Why is it difficult to protect biodiversity?
Arresting the loss of diversity will be extremely difficult. The traditional “just set aside a preserve” approach is almost certain to be inadequate because of factors such as runaway human population growth, acid rains, and climate change induced by human beings.

What are the major challenges of wildlife?
The data revealed that deforestation; habitat loss, degradation and fragmentation; agriculture expansion; settlement; overutilization of forest resources; human-wildlife conflict; fire; district’s administration problems and wildlife hunting were the major wildlife threats in the area.
Why should we preserve biodiversity?
Keeping biodiverse ecosystems intact helps humans stay healthy. Research indicates that there is a close link between disease outbreaks and the degradation of nature. Seventy percent of emerging viral diseases have spread from animals to humans.
Why is it often a challenge to conserve biodiversity in an urban area?
The biological diversity of urban areas has also been among the most severely affected by the introduction of animal species, which prey on native animal populations, compete for limited resources, and act as vectors for novel diseases and parasites to which native organisms can be particularly susceptible.
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
What are the issues and challenges in preservation and conservation?
Generally the challenge to preservation and conservation the record are: 1) Budgeting, 2) Human Source, 3) Technology, and 4) Rules and Policy.
What are the challenges of ecosystem?
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
