How is biodiversity loss a threat to humans?
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 are two different types of biodiversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.
What are the main threats to biodiversity in rainforest ecosystems?
Deforestation and fragmentation, over-exploitation, invasive species, and climate change are the major factors due to which the biodiversity of tropical forest had declined at an alarming rate.
What are the 5 factors that affect biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.
What are the main causes of threat to ecosystem?
1 Answer. (i) Hunting and poaching by greedy hunters for commercial purpose and their profits. (ii) Pollution due to chemical and industrial waste and acid deposits. (iii) Introduction of alien species and reckless cutting of forests to bring land under cultivation.
What is the greatest threat to biodiversity today?

Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.

What are the three biggest threats to biodiversity?
The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. The first two of these are a direct result of human population growth and resource use.
What increases species diversity?
In most suc- cessional sequences, species richness increases over time as new. species colonise the habitat, and then either remains stable or. declines as a result of processes such as competition (Peet, 1992).
