👉 Extinctions are natural processes that occur when species of plants, animals or other organisms die out. These events can result from a variety of factors such as habitat loss, climate change, pollution, and human activities. Extinctions can have significant impacts on ecosystems, including changes in biodiversity, increased competition for resources, and shifts in the distribution of plant and animal species. Extinctions are often associated with major environmental changes that lead to a decline in biodiversity and a reduction in ecosystem services provided by plants and animals
