Answer:

Changes in environmental conditions like floods or forest fires, always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species. If humans are hunting for predators like jaguars, this would affect the food chain and cause a loss of biodiversity. The prey would survive and reproduce more because there would be fewer predators to eat them. Therefore, the population can increase. Species can also evolve to fit the environmental conditions. For example, if there is a major drought in an area, some organisms could adapt and evolve to the drought. However, the organisms that can't evolve would die and would also cause a loss of biodiversity. Environmental conditions like climate change affect many organisms. One pine tree species went extinct because of climate change. The seeds couldn't grow and reproduce in the weather, so the organism gradually went extinct.

The statement is a short one, but it manages to sum up what happens in nature in a simplified manner.

All the species have evolved to a certain type of environment, thus being perfectly well adapted to certain living conditions, and developing traits that are advantageous for the survival in that particular environment. But the Earth is constantly changing, and those changes result in changes of the environment, sometimes gradually, sometimes very quickly. The loss or change of environment always has huge impact on the species. Some go extinct, especially the ones that have been too specialized, while the more opportunistic and less specialized species often manage to survive. The ones that manage to survive face a new environment, so they evolve in a way that is advantageous for them to survive in the new environment, thus giving rise to new species. Other species may already have the required traits for the new environment but have been living in different area, so they will gradually move in this new environment as it suits them, thus having a situation where the ecosystems will eventually be totally changed and unrecognizable from the predeceasing ecosystems.
