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 will be the biggest impact of loss of biodiversity?
Economic and societal effects
The loss of biodiversity among these critical natural resources
threatens global food security and the development of new pharmaceuticals to deal with future diseases
. Simplified, homogenized ecosystems can also represent an aesthetic loss.
What are the effects of loss of biodiversity on the environment?
At higher levels of extinction (41 to 60 percent of species), the effects of species loss ranked with those of many other major drivers of environmental change, such as ozone pollution,
acid deposition on forests
and nutrient pollution.
What are the causes and effects of 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.
How does loss of biodiversity affect humans?
More… 2.1 Biodiversity loss has
negative effects on
several aspects of human well-being, such as food security, vulnerability to natural disasters, energy security, and access to clean water and raw materials. It also affects human health, social relations, and freedom of choice.
What are the main causes of biodiversity loss?
- Climate change.
- Pollution.
- Destruction of habitats.

How does loss of biodiversity 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
.
What is the importance of biodiversity?
Biodiversity
supports ecosystems to provide and purify water
. Every two minutes a child dies from a water-borne disease. But through the continuous recycling of water, biodiversity maintains ecosystem services needed to sustain drinking water supplies. Ecosystems also play a significant role in purifying water.
