Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
What happens when there is less 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.
Why is it bad if biodiversity decreases?
“The continuing loss of biodiversity will undermine our ability for poverty reduction, food and water security, human health and the overall goal of leaving nobody behind.”
What does low biodiversity mean?
Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
What is caused due to loss of 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.
What is the disadvantages of low biodiversity in economics?
Disadvantages of low diversity are as follows: Diseases are more likely to spread. Ecosystem with low diversity is less productive. … There is a lot of pressure for food and energy on the ecosystem.
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 is the biggest threat to the loss of biodiversity essay?
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.
