Changes in biodiversity can be caused by a variety of factors, including:

• Habitat loss and fragmentation: When habitats are destroyed or divided into smaller pieces, it can make it difficult for species to survive and reproduce.
• Invasive species: Invasive species are plants or animals that are introduced to a new environment where they have no natural predators or competitors. They can quickly outcompete native species and lead to biodiversity loss.
• Pollution: Pollution can contaminate ecosystems and make them uninhabitable for some species.
• Overexploitation: Overexploitation is the harvesting of wild plants or animals at a rate that is unsustainable. It can lead to population declines and extinctions.
• Climate change: Climate change is causing changes in temperature, precipitation, and other environmental conditions. This can make it difficult for species to adapt and survive.

Changes in biodiversity can affect ecosystem stability in a number of ways:

• Reduced resilience: More diverse ecosystems are more resilient to disturbances, such as droughts, floods, and wildfires. When biodiversity is reduced, ecosystems are more likely to collapse after a disturbance.
• Altered ecosystem functions: Biodiversity plays a vital role in many ecosystem functions, such as pollination, pest control, and water filtration. When biodiversity is reduced, these ecosystem functions can be impaired.
• Cascading effects: The loss of one species can have a cascading effect on other species in the ecosystem. For example, if a predator is lost, its prey populations may increase and overgraze vegetation. This can lead to soil erosion and changes in the entire ecosystem.

Loss of biodiversity can have a significant impact on the natural environment:

• Reduced ecosystem services: Biodiversity provides us with a wide range of ecosystem services, such as food, clean water, and air purification. When biodiversity is lost, these services are also at risk.
• Increased vulnerability to climate change: Biodiversity helps ecosystems to adapt to climate change. When biodiversity is lost, ecosystems are more vulnerable to the impacts of climate change.
• Threat to human health: Biodiversity is also important for human health. Many plants and animals are used to produce medicines and other products that we rely on. When biodiversity is lost, these resources are also at risk.

It is important to protect biodiversity in order to maintain ecosystem stability and ensure the health of the natural environment. We can do this by reducing our impact on the environment, such as by reducing our consumption of resources and our production of pollution. We can also support efforts to conserve and restore habitats and to control invasive species.

Biodiverse ecosystems are more stable and resilient to disruptions such as climate change, disease outbreaks or invasive species. Loss of biodiversity can reduce an ecosystem's ability to recover from these disturbances and increase the risk of ecosystem collapse. Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change. 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 ecosystems and extinctions of species and local populations. Biological diversity and balance can be impacted by both natural forces and human activities happening over different time and spatial scales. Changes can occur over millions of years, or be rapid and dramatic. Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.). Plants and oceans act as major carbon sinks. In short, biodiversity provides us with clean air, fresh water, and good quality soil and crop pollination. It helps us fight climate change and adapt to it as well reduce the impact of natural hazards.Not only does biodiversity loss impact individual species, but it also alters their symbiotic interrelations with other species and their habitats. In turn, ecosystem functions and aforementioned services are disrupted, with widespread consequences for humans and other life on Earth. The risk of species extinction increases with every degree of warming. In the ocean, rising temperatures increase the risk of irreversible loss of marine and coastal ecosystems. Live coral reefs, for instance, have nearly halved in the past 150 years, and further warming threatens to destroy almost all remaining reefs.
