Biodiversity is the variety of species present in the biosphere; the main goal of conservationists is to preserve biodiversity. … Current human-caused biodiversity loss is the result activities such as habitat destruction, the introduction of exotic invasive species, and the over-harvesting of species.
What is the main objective of conservation of biodiversity?
Biodiversity conservation has three main objectives: To preserve the diversity of species. Sustainable utilization of species and ecosystem. To maintain life-supporting systems and essential ecological processes.
What refers to loss of biodiversity?
Biodiversity loss refers to the decline or disappearance of biological diversity, understood as the variety of living things that inhabit the planet, its different levels of biological organisation and their respective genetic variability, as well as the natural patterns present in ecosystems.
Which is the reason for the loss of biodiversity answer?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
What are the effects of loss of biodiversity?
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.
What are the aims and objectives of biodiversity?
It promotes at least one of the three objectives of the Convention: the conservation of bio-diversity, sustainable use of its components (ecosystems, species or genetic resources), or fair and equitable sharing of the benefits of the utilisation of genetic resources.
What are the two main objective of conserving resources?
For social responsibility. To ensure constant safe water supply.
Where does loss of biodiversity occur?
Ecologists emphasize that habitat loss (typically from the conversion of forests, wetlands, grasslands, and other natural areas to urban and agricultural uses) and invasive species are the primary drivers of biodiversity loss, but they acknowledge that climate change could become a primary driver as the 21st century …

What are the major factors that are responsible for the loss of biodiversity what steps are needed to prevent them?
The following steps are needed to prevent them:
- Efforts should be made to preserve the species.
- Proper planning and management should be undertaken to stop extinction of species.

- Hunting must be restricted.
- International trade in wild animals should be regulated.
How does biodiversity loss affect the economy?
Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. … Decreased biodiversity can lead to increased transmission of diseases to humans and increased healthcare costs.
How does loss of biodiversity affect ecosystems?
Loss of biodiversity undermines the ability of ecosystems to function effectively and efficiently and thus undermines nature’s ability to support a healthy environment. This is particularly important in a changing climate in which loss of biodiversity reduces nature’s resilience to change.
What is biodiversity Why is biodiversity important for human life?
Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.
