Important direct drivers include climate change, nutrient pollution, land conversion leading to habitat change, overexploitation, and invasive species and diseases. that happen intermittently. Changes in ecosystem services can feed back to alter drivers.
What are the drivers and effects of environmental change?
Taken together, these five drivers are bringing about changes in natural as well as social systems. These impacts range from resource depletion to biodiversity loss, water scarcity, changes in the hydrological cycle, health impacts, and ecosystem degradation as well as pollution.
What are 4 environmental changes?
Major changes such as land subsidence, climate change, habit alteration, water quality, population growth, water exports, invasion by nonnative species, and in-delta physical changes will continue to change the delta during the current century and beyond.
What are examples of environmental changes?
Examples of these global environmental changes include climate change, freshwater shortages, loss of biodiversity (with consequent changes to functioning of ecosystems), and exhaustion of fisheries.
What are environmental drivers?
A driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely, by altering one or more direct drivers.
One of the drivers of environmental change is population growth and demographic change. Demographic change includes the movement of people within a country to new locations, and changes in the composition of the population (e.g. through changes in the relative numbers of different age groups).

What are five examples of environmental changes that affect evolution?
Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture. All evolutionary biologists agree on the first three of these forces, although there have been disputes at times about the relative importance of each force.
