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.
How biodiversity loss affects the environment?
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 are the causes of loss of diversity biodiversity?
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.
How does species diversity affect biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
What affects biological diversity?
Biodiversity change is caused by a range of drivers. … Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
How does loss of biodiversity affect sustainable development?
As biodiversity is lost, there is a risk that some thresholds will be passed, undermining the functioning of the earth system. Conversely, the conservation and sustainable use of biodiversity contributes to sustainable development and mitigation and adaptation to climate change.
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.
Why is biodiversity loss important?
Biodiversity is essential to increase the resilience of communities and reduce their vulnerability in the face of shocks such as climate change and natural disasters. Biodiversity loss destabilizes ecosystems that can regulate the climate and mitigation of floods.
How does loss of biodiversity affect animals?
The loss of biodiversity has two significant impacts on human health and the spread of disease. … 8 As habitats are broken apart and reduced in size, these animals become more common, winning out over the species that do not typically transmit disease.
What do you mean by 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.
Why does the biodiversity of an ecosystem affect its resilience?
Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.
What are the factors affecting ecosystem degradation and loss?
One of the main causes that contributes to the degradation of ecosystems is the deforestation due to the advance of the agriculture frontier and inappropriate forest exploitation. More lands are deforested for commercial agriculture and live-stock rearing, and due to overexploitation of forest for wood and energy.
What is the conclusion of loss of biodiversity?
Conclusion: Most biodiversity resources are consumed by humans, so it is their primary responsibility to preserve and protect biodiversity to protect the earth. The richness of the species, the ecosystem, the environment and the sustainable growth of life on earth is important.
