Compost: is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Compost is a key ingredient in organic farming. At the simplest level, the process of composting simply requires making a heap of wetted organic matter; leaves, “green” food waste, and waiting for the materials to break down into humus after a period of weeks or months to become e.g. soil. Worms and fungi further break up the material. Aerobic bacteria manage the chemical process by converting the inputs into heat, carbon dioxide and ammonium. The ammonium is further converted by bacteria into plant-nourishing nitrites and nitrates through the process of nitrification. Compost can be rich in nutrients. It is used in gardens, landscaping, horticulture, and agriculture. The compost itself is beneficial for the land in many ways, including as a soil conditioner, a fertilizer, addition of vital humus or humic acids, and as a natural pesticide for soil. In ecosystems, compost is useful for erosion control, land and stream reclamation, wetland construction, and as landfill cover. Composting can be done at home or for an intire society.
Ecologist: An understanding of how biodiversity affects ecological function is an important focus area in ecological studies. Ecologists are concerned with ecosystems as a whole and, within them, the abundance and distribution of organisms (people, plants, animals) and the relationships between organisms and their environment. Ecologists usually choose a specialist area (e.g. freshwater, marine, terrestrial, fauna, flora) and then carry out a wide range of tasks relating to that area. When starting out, ecologists often conduct surveys to identify, record and monitor species and their habitats. With career progression, work is likely to become more wide-ranging, with senior ecologists being more involved in policy and management work. Ecologist seek to explain:
- Life processes and adaptations
- Distribution and abundance of organisms
- The movement of materials and energy through living communities
- The successional development of ecosystems, and
- The abundance and distribution of biodiversity in the context of the environment.
An ecologist may be involved in environmental impact assessments which are required by law for planning permission. Alternatively, they may collect and manage biological information for national databases or produce comprehensive lists of species that need to be monitored and protected.
Ecology: is the scientific study of the relationships that living organisms have with each other and with their natural environment. Topics of interest to ecologists include the composition, distribution, amount (biomass), number, and changing states of organisms within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecology is an interdisciplinary field that includes biology and Earth science. Ecology is not synonymous with environment, environmentalism, natural history, or environmental science. It is closely related to evolutionary biology, genetics, and ethology. Ecology is a human science as well. Ecology addresses the full scale of life, from tiny bacteria to processes that span the entire planet. Ecologists study many diverse and complex relations among species, such as predation and pollination. The diversity of life is organized into different habitats, from terrestrial (middle) to aquatic ecosystems.
Ecosystem: Everything in the natural world is connected. An ecosystem is a community of living and non-living things that work together. Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together. If there isn’t enough light or water or if the soil doesn’t have the right nutrients, the plants will die. If the plants die, animals that depend on them will die. If the animals that depend on the plants die, any animals that depends on those animals will die. Ecosystems in nature work the same way. All the parts work together to make a balanced system.
GMO: A genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Organisms that have been genetically modified include micro-organisms such as bacteria and yeast, plants, fish, and mammals. GMOs are the source of genetically modified foods, and are also widely used in scientific research and to produce goods other than food. GMOs are used in biological and medical research, production of pharmaceutical drugs, experimental medicine, and agriculture.
Organic Certification: a certification process for producers of organic food and other organic agricultural products. Any business directly involved in food production can be certified, including seed suppliers, farmers, food processors, retailers and restaurants. Requirements vary from country to country, and generally involve a set of production standards for growing, storage, processing, packaging and shipping that include:
- no human sewage sludge fertilizer used in cultivation of plants or feed of animals
- avoidance of synthetic chemical inputs not on the National List of Allowed and Prohibited Substances (e.g. fertilizer, pesticides, antibiotics, food additives, etc.), genetically modified organisms, irradiation, and the use of sewage sludge;
- use of farmland that has been free from prohibited synthetic chemicals for a number of years;
- keeping detailed written production and sales records;
- maintaining strict physical separation of organic products from non-certified products;
- undergoing periodic on-site inspections.
In some countries, certification is overseen by the government, and commercial use of the term organic is legally restricted. Certified organic producers are also subject to the same agricultural, food safety and other government regulations that apply to non-certified producers. To put the word “organic” on a food product is a valuable marketing advantage in today’s consumer market, but does not guarantee the product is legitimately organic.
Organic Foods: are foods that are produced using methods that do not involve modern synthetic inputs such as synthetic pesticides and chemical fertilizers. Organic foods are also not processed using irradiation, industrial solvents, or chemical food additives. Organic food production is a heavily regulated industry and many countries require producers to obtain special certification in order to market food as organic.
Recycling: is processing used materials, waste, into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for “conventional” waste disposal, and lower greenhouse gas emissions. Recycling is a key component of modern waste reduction and is the third component of the “Reduce, Reuse, Recycle” waste hierarchy. Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste – such as food or garden waste – is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing.
Sustainability: is the capacity to endure through renewal, maintenance, and sustenance, or nourishment, in contrast to durability, the capacity to endure through unchanging resistance to change. For humans in social systems or ecosystems, sustainability is the long-term maintenance of responsibility, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse, robust, and productive over time, a necessary precondition for the well-being of humans and other organisms. Long-lived and healthy wetlands and forests are examples of sustainable biological systems.
