The burning of fossil fuels releases greenhouse gases into the atmosphere, which trap heat and cause the Earth's temperature to rise.

Climate change can cause habitat loss, changes in food availability, and increased competition for resources, leading to the extinction of some species and the adaptation of others.

Species that live in polar regions are particularly vulnerable to climate change because they are adapted to cold temperatures and may not be able to survive in warmer conditions.

Natural selection, evolution, and adaptation are all terms used to describe the process by which species adapt to changing environmental conditions.

Extinction is the term used to describe the process by which species become extinct.

Endangered, vulnerable, and threatened are all terms used to describe a species that is at risk of extinction.

Extinct is the term used to describe a species that has already gone extinct.

Near threatened is the term used to describe a species that is not currently at risk of extinction but could become so in the future.

Least concern is the term used to describe a species that is not at risk of extinction and is not likely to become so in the future.

Genus is the term used to describe a group of species that are closely related and share a common ancestor.

Family is the term used to describe a group of genera that are closely related and share a common ancestor.

Order is the term used to describe a group of families that are closely related and share a common ancestor.

Class is the term used to describe a group of orders that are closely related and share a common ancestor.

Phylum is the term used to describe a group of classes that are closely related and share a common ancestor.

Kingdom is the term used to describe a group of phyla that are closely related and share a common ancestor.
