Biodiversity or Biological diversity: It refers to the variety or organisms existing on the earth. Their interrelationships and their relationship with the environment. It includes variety of plants, animals and microorganisms. Flora and Fauna: The plants found in a particular area are termed as flora area.
What are the threats to sustainability?
The greatest threats to the sustainable development on earth are: population growth and urbanisation, energy use and global warming, excessive waste generation and the subsequent pollution of soil, air, and water, transportation in cities, and limited supply of resources. Many of them are interrelated.

What factors influence biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7). No single measure or indicator represents the totality of the various drivers.
What is biodiversity for kids?
Biodiversity is the rich variety of life on Earth. There’s variety in genes, variety among species, and a variety of ecosystems. Everything is interconnected, or dependent on everything else!
How can we protect biodiversity?
- Support local farms. …
- Save the bees! …
- Plant local flowers, fruits and vegetables. …
- Take shorter showers! …
- Respect local habitats. …
- Know the source!
How do animals affect biodiversity?
When grazing animals reduced dominance by feeding on abundant species that appealed to their tastes, the grazers increased biodiversity by freeing up resources for other, less dominant plant species. … The results suggest that management of dominance, not of grazing activity per se, is key to conserving biodiversity.
How does biodiversity of animals affect humans?
Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.
How biodiversity is affected and endangered by human activities?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
What are the three pressures that lead to biodiversity?
Three major interacting drivers affecting all these pressures have been (and will be) climate, human population growth and the demands placed on the environment to support human lifestyles. It will be important to address all three of these drivers if pressures on biodiversity are to be reduced to desirable levels.
Why biodiversity is under threat?
Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
What are the threats to biodiversity at local national and global level?
A team of leading researchers have produced global maps for the six main threats affecting terrestrial amphibians, birds and mammals: agriculture, hunting and trapping, logging, pollution, invasive species, and climate change.
What are the threats to the Indian biodiversity?
Major threats to biodiversity not only emerge from ever-increasing human population but also multiplied by it. Deforestation, land use/cover changes, over-utilization of natural resources, poaching, pollution, etc., are some of the direct outcomes of increasing population leading to erosion or loss of biodiversity.
