**9. a. Describe a Naturally Occurring Environmental Change that Could Contribute to the Extinction of a Species**

The natural world is constantly evolving, and environmental changes can have a significant impact on the survival of species. In this article, we will explore a naturally occurring environmental change that could contribute to the extinction of a species and discuss how it could both positively and negatively affect biodiversity.

Climate Change: A Threat to Biodiversity

One of the most significant naturally occurring environmental changes that could contribute to the extinction of a species is climate change. Climate change refers to the long-term warming of the planet due to an increase in average global temperatures. This warming is primarily caused by human activities such as burning fossil fuels and deforestation, but it also has natural causes such as changes in the Earth's orbit and volcanic eruptions.

How Climate Change Affects Biodiversity

Climate change can have both positive and negative effects on biodiversity. On the one hand, climate change can lead to the extinction of species that are unable to adapt to the changing environmental conditions. This can result in a loss of genetic diversity and a reduction in the number of species that are able to survive in a given ecosystem.

On the other hand, climate change can also lead to the expansion of species into new areas, which can result in an increase in biodiversity. For example, as the climate warms, some species of plants and animals may be able to migrate to new areas and establish themselves, leading to an increase in the number of species present in a given ecosystem.

Positive Effects of Climate Change on Biodiversity

While climate change can have negative effects on biodiversity, it can also have positive effects. Some of the positive effects of climate change on biodiversity include:

Increased range of species: As the climate warms, some species may be able to expand their range into new areas, leading to an increase in biodiversity.
New habitats: Climate change can lead to the creation of new habitats, such as coral reefs and mangrove forests, which can support a wide range of species.
Increased productivity: Climate change can lead to an increase in productivity in some ecosystems, such as the Amazon rainforest, which can support a wide range of species.

Negative Effects of Climate Change on Biodiversity

While climate change can have positive effects on biodiversity, it can also have negative effects. Some of the negative effects of climate change on biodiversity include:

Extinction of species: Climate change can lead to the extinction of species that are unable to adapt to the changing environmental conditions.
Loss of genetic diversity: Climate change can lead to a loss of genetic diversity, which can make species more vulnerable to extinction.
Disruption of ecosystems: Climate change can disrupt the delicate balance of ecosystems, leading to a loss of biodiversity.

In conclusion, climate change is a naturally occurring environmental change that could contribute to the extinction of a species. While it can have positive effects on biodiversity, such as increasing the range of species and creating new habitats, it can also have negative effects, such as leading to the extinction of species and a loss of genetic diversity. It is essential to take action to mitigate the effects of climate change and protect biodiversity.
