What is the greatest threat to biodiversity today?
Habitat loss is the single greatest threat to biodiversity on Earth today and in fact it is the second largest threat to our existence on this planet next to Climate Change.
What is the cause of declining biodiversity?
Habitat loss is the primary cause of decline for species and populations because it removes the flora and fauna that each species requires for life. When more and more land use occurs within areas of high species richness, loss of biodiversity is greatly exacerbated and species extinctions increase.
How do humans affect biodiversity negatively?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
What will happen if we lose biodiversity?
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.
