sustainability

Examples of sustainability in the following topics:

• Habitat Loss and Sustainability

  • Through increased adoption of sustainable practices, we can reduce habitat loss and its consequences.
  • Long-lived and healthy wetlands and forests are examples of sustainable biological systems.
  • Sustainability requires the reconciliation of environmental, social, and economic demands, which are also referred to as the "three pillars" of sustainability.
  • At the local human scale, sustainability benefits accrue from the creation of green cities and sustainable parks and gardens.
  • Describe the effects of habitat loss to biodiversity and concept of sustainability

• Managing Fisheries

  • Despite considerable effort, few fisheries on the planet are managed for sustainability.
  • Sustainable seafood is a movement that has gained momentum as more people become aware of overfishing and environmentally-destructive fishing methods.
  • Sustainable seafood is seafood from either fished or farmed sources that can maintain or increase production in the future without jeopardizing the ecosystems from which it was acquired.
  • Seafood species that grow quickly and breed young, such as anchovies and sardines, are much more resistant to overfishing and are therefore labeled "sustainable" and promoted as good alternatives.

• Temperate Grasslands

  • Plant growth is possible when temperatures are warm enough and when ample water is available to sustain it, which typically occurs in the spring, summer, and fall.
  • The dominant vegetation tends to consist of grasses; some prairies sustain populations of grazing animals .

• Introduction to Ecology

  • These processes are sustained by organisms with specific life-history traits.
  • Ecosystems sustain life-supporting functions and produce natural capital, such as biomass production (food, fuel, fiber and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil formation, erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value.

• Symbiosis between Bacteria and Eukaryotes

  • The use of legumes is an excellent alternative to chemical fertilization and is of special interest to sustainable agriculture, which seeks to minimize the use of chemicals and conserve natural resources.
  • Therefore, the use of rhizobia as biofertilizers is a sustainable practice.

• Homeostasis: Thermoregulation

  • However, endothermic animals must sustain their higher metabolism by eating more food more often.
  • For example, a mouse (endotherm) must consume food every day to sustain high its metabolism, while a snake (ectotherm) may only eat once a month because its metabolism is much lower.
  • Sustained energy output of an endothermic animal (mammal) and an ectothermic animal (reptile) as a function of core temperature.

• Overharvesting

  • Sustained overharvesting can lead to the destruction of the resource, and is one of the five main activities - along with pollution, introduced species, habitat fragmentation, and habitat destruction - that threaten global biodiversity today.
  • Exponential increase in human population, expanding markets, and increasing demand, combined with improved access and techniques for capture, are causing the exploitation of many species beyond sustainable levels.
  • As mentioned above, sustained overharvesting is one of the primary threats to biodiversity.

• The Chemical Composition of Plants

  • Plant cells need essential substances, collectively called nutrients, to sustain life.

• Soil Composition

  • A good, healthy soil has sufficient air, water, minerals, and organic material to promote and sustain plant life.

• The Energy Cycle

  • These two powerhouse processes, photosynthesis and cellular respiration, function in biological, cyclical harmony to allow organisms to access life-sustaining energy that originates millions of miles away in the sun.
