What is biodiversity What is its importance?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
What is biodiversity in PDF?
Abstract. Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. It refers to genetic variation, ecosystem variation, species variation (number of species) within an area, biome or planet.
Whats is biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What is biodiversity essay?
Essay on Biodiversity– Biodiversity is the presence of different species of plants and animals on the earth. Moreover, it is also called biological diversity as it is related to the variety of species of flora and fauna. Biodiversity plays a major role in maintaining the balance of the earth.
How valuable is biodiversity for students like you?
Biodiversity has a fundamental value to humans because we are so dependent on it for our cultural, economic, and environmental well-being. Biodiversity forms the backbone of viable ecosystems on which we depend on for basic necessities, security, and health.
Why is biodiversity important to students?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What are 5 benefits of biodiversity?
Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.
What is the importance of biodiversity to human health?
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
What is the impact of biodiversity in your community?
Biodiversity gives resilience—from the microbes that contribute to the formation of the human biome to the genes that help us adapt to stress in the environment—supports all forms of livelihoods, may help regulate disease, and is necessary for physical, mental, and spiritual health and social well-being.
What are the effects of biodiversity?
These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
What are the 5 main threats to biodiversity?
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 causes and effects of biodiversity?
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
What are the causes of biodiversity?
8 Major Causes of Biodiversity – Explained!
- Habitat Loss and Fragmentation: A habitat is the place where a plant or animal naturally lives.
- Over-exploitation for Commercialization: ADVERTISEMENTS:
- Invasive Species:
- Pollution:
- Global Climate Change:
- Population Growth and Over-consumption:
- Illegal Wildlife Trade:
- Species extinction:
What is the social benefit of biodiversity?
Biodiversity is important in supporting vital ecosystem services (ES) such as provision of clean water, but can also provide social benefits, such as improved employment. The report focussed on the impact of biodiversity on employment and the value of biodiversity and the services provided for vulnerable rural people.
What are main causes of biodiversity loss?
CAUSES OF BIODIVERSITY LOSS
- Climate change.
- Pollution.
- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
- Extinction of species.
- Threat to human beings.
- Proliferation of pests.
What happens if biodiversity is lost?
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.
Can we still recover the lost biodiversity?
Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area.
Why is biodiversity bad?
Biodiversity loss and ecosystem change can increase the risk of emergence or spread of infectious diseases in animals, plants and humans, including economically important livestock diseases, zoonotic outbreaks and global pandemics.
What are the negative effects of biodiversity?
Biodiversity/species diversity can have negative effects on human well-being, e.g., increased concentrations of mercury in top predators (the fish we eat) in aquatic ecosystems because of longer food chains or the correlation between biodiversity in general and diversity of pathogens and pests.
How do humans maintain biodiversity?
Attract “good” insects by planting pollen and nectar plants. Maintain wetlands by conserving water and reducing irrigation. Avoid draining water bodies on your property. Construct fences to protect riparian areas and other sensitive habitats from trampling and other disturbances.
How do humans contribute to the loss of biodiversity?
The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and …
What is the greatest threat to biodiversity today?
Habitat loss
What are the three factors of biodiversity?
Biodiversity is an abbreviation for biological diversity. It generally means the ‘diversity of flora and fauna (plants and animals)’ (IB definition). It has three factors, ecosystem, species and genetics.
Does biodiversity have value?
Biodiversity has a fundamental value to humans because we are so dependent on it for our cultural, economic, and environmental well-being. Elements of biodiversity can contribute to cultural identity, and many ecosystem characteristics are frequently incorporated into cultural traditions.
Does biodiversity need human beings?
So we can say that the human doesn’t have a very important role to play in sustaining diversity rather the presence of human being is becoming the cause of destruction of biodiversity. humans won’t be able to survive without biodiversity. Greater is the biodiversity, better the chances of survival.
