Which is most likely an effect of long-term environmental changes? death migration loss of habitat speciation

The correct answer is speciation.

Explanation:

Due to the climatic changes that are occurring, the species are forced to adapt to survive. This sometimes causes species to evolve and even new ones are created.

If we talk about plants, climate change is playing a negative role with these organisms and the diversity of plants we know today is likely to fall dramatically in the next century.

This will also affect human and animal life, or the extinction of some species.

This will not take away that new species continue to form. Especially those that manage to evolve and adapt to new ways of life, new habitats and the climate that we will have in the future due to climate change due to pollution.
