Human Impact
Fish decline:
Approximately 40% of the entire fish population reside in the freshwater biome. Unfortunately, the amount of freshwater fish has declined by 20% in just the past 20 years. One of the main reasons for this is human disturbances, for they're continuously damaging the habitat for these creatures in numerous ways. One example, as seen above in the first image is pollution and the filling of wetlands. Habitats destroyed: When humans take water from these environments it causes them to shrink. When this happens many plants and animals's habitats become degraded. Not to mention that the creation of dams block the original and natural routes that fishes use for migration. The reason that is so significant is because it affects the entire population and community. Pollution: Although many people are naive to the runoff from urban and agricultural areas, its impact is surprisingly large. Not only does it ham the freshwater biome but it additionally affects the ground water supply as well. This pollution can be absolutely toxic to the organisms living and ingesting the water. Global Warming: The process of global warming caused by humans can be quite devastating to plants. For example, it can produce droughts and floods that have the potential to wipe out an entire portion of the freshwater community. Nevertheless, when the balance of nature is disturbed, the native animals are at risk from invasive migrating species. |
