Understanding Ecosystem Disturbances: Wind and Fire Impacts
Ecosystem Disturbances: Wind and Fire Impacts
A disturbance is a relatively discrete event in time that causes a disruption in ecosystems, changing the substrate and availability of resources, and creating opportunities for the establishment of new individuals. Allogenic disturbances are partly allogenic and autogenic because their impact is the result of both the magnitude of the disturbance and the susceptibility of the community to the particular type of alteration.

Harnessing Tidal Energy: Stream, Barrage, Dynamic, and Lagoon Power
Harnessing Tidal Energy
Tidal stream generators (TSGs) utilize the kinetic energy of moving water to power turbines, similar to wind turbines. Some TSGs can be integrated into existing bridge structures, minimizing aesthetic impact. Land constrictions, such as straits or inlets, can create high-velocity sites suitable for turbines. These turbines can be horizontal, vertical, open, or ducted and are typically placed near the bottom of the water column.
Tidal Barrage

Environmental Impacts of Human Activities
A significant change in the environment caused by human activity is called an environmental impact.
Types of Impacts
According to the Conclusions
- Positive effect: Improves the environment or human nature itself.
- Adverse impacts: Harm human nature itself or the environment.
What Affects the Environment
- Environmental Impacts: Changes to some other living beings, bodies of water, air, and land relief.
- Human impacts on the environment: Directly affect our way of life.
Environmental Issues: Biodiversity, Ozone, and Sustainability
Biodiversity
Biodiversity is the full variety of life on Earth, encompassing every plant and animal species. It also includes the variety of ecosystems and the differences in genetic diversity within species.
Ozone Layer
The ozone layer is the area of the stratosphere that contains a relatively high concentration of ozone. The reduction in its thickness is due to the chlorine contained in Chlorofluorocarbons (CFCs) used in aerosols and refrigerants. This problem affects plant, animal, and human life.

Chile’s Far North: Regions and Towns
This section covers the following regions: Region I (Tarapacá), Region II (Antofagasta), and Region XV (Arica and Parinacota). Geographically, it extends from the northern limit line (Concord), approximately at the 18.5th parallel, to the Copiapó River, approximately at the 26.5th parallel (ecotones).
Characteristics of the Far North
- Characterized by absolute desert, devoid of vegetation except for some isolated areas.
- Plains over a thousand feet high.
- Warm, even
