Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [ 45 ] because affected ecosystems can no longer provide the same quality of ecosystem services , such as crop pollination , cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism .
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Most of the exponential human population growth worldwide is occurring in or close to biodiversity hotspots. [6] This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity.

Habitats are being destroyed daily without considering the damage done to biodiversity on both micro and macro levels. Why we must protect our biodiversity which is declining at an alarming rate ...
Biodiversity loss due to pollution is also a threat in Wisconsin, which ranks eighth in the country. According to the report, the threat is fairly uniform across the state with the greatest threat ...
Biodiversity generally refers to the variety and variability of life on Earth, and is represented by the number of different species there are on the planet. Since its introduction, Homo sapiens (the human species) has been killing off entire species either directly (such as through hunting) or indirectly (such as by destroying habitats ...
