As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Endemic organisms with limited ranges are most affected by habitat destruction, mainly because these organisms are not found anywhere else in the world, and thus have less chance of recovering. Many endemic organisms have very specific requirements for their survival that can only be found within a certain ecosystem, resulting in their extinction.
Human activities have introduced disturbances into ecosystems worldwide on a large scale, resulting in widespread range expansion and rapid evolution of disturbance-adapted species. [7] Agricultural practices create novel ecosystems, known as agroecosystems , which are colonized by plant species adapted to disturbance and enforce evolutionary ...
The Aral Sea is an example of a collapsed ecosystem. [1] (image source: NASA) An ecosystem, short for ecological system, is defined as a collection of interacting organisms within a biophysical environment. [2]: 458 Ecosystems are never static, and are continually subject to both stabilizing and destabilizing processes. [3]
Example of seascape connectivity among different patch types in a tropical seascape and the flow of ecosystem services. Ecological linkages are depicted by arrows: terrestrial (brown); mangroves (green); seagrasses (blue); and coral reefs (red). Potential feedbacks from human impacts are also shown (yellow arrows).

From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of ...
Although ecosystems are most commonly categorized by their structure and geography, there are also other ways to categorize and classify ecosystems such as by their level of human impact (see anthropogenic biome), or by their integration with social processes or technological processes or their novelty (e.g. novel ecosystem).
