Biotechnology is a technology based on biology, especially when used in agriculture, food science, and medicine.\n\nOf the many different definitions available, the one formulated by the UN Convention on Biological Diversity is one of the broadest:\n\n"Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use." (Article 2. Use of Terms) \nBiotechnology can also be defined as the manipulation of organisms to do practical things and to provide useful products.\n\nOne section of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer, milk products, and skin). Naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and produce biological weapons.

They have found methane,that means there is some kind of organic life

Non-biodegradeable means that when you throw something out, it does not fall apart on its own in nature (like a napkin or paper gets mushy and breaks apart when wet, or how food rots).\n\nThis is a problem because all this waste accumulates or builds up. Thus more and more space is needed to bury it. Alternatives to placing it in the ground is burning it, and this is bad because it releases chemicals into the air that can harm the environment and people.\n\nBest solution is to recycle plastic, that is people shred it or melt it and reuse it. Other uses are to take plastic bags and mix it with glue and wood and make a new type of wood that is very resistant to water damage. This type of wood is used alot now in lawn furniture and porches.

Well, here's a summary of what I managed to find online:\n-~500 million tons of methane are put into the atmosphere each year, total, from all sources.\n-each of the 1.3 billion cattle in the world today belch out about 1/2 lb of methane each day. All animals are responsible for about 15% of the total, cattle responsible for most of it (12%).\n-the other main sources are landfills, coal mines, rice paddies, and peat bogs.\nCouldn't find a specific amount attributable to humans.\nHope that helps.

The true definition of bioassimilation:\n The accumulation of a substance within a habitat.\n\nThis can mean how an organic material grows in a habitat (ie. limited by predators or grows uncontrollably because it is the dominant plant(as it happens when foriedn plants contaminate a new environ).

get yourself a bio-cycle system or a worm pit. serious, they have them in oz. it's a pit of worms that processes all of the junk (food, faeces) and puts the left over clean fluid under the garden beds. the ultimate  compost heap

Renewable energy resources may be used directly, or used to create other more convenient forms of energy. Examples of direct use are solar ovens, geothermal heating, and water- and windmills. Examples of indirect use which require energy harvesting are electricity generation through wind turbines or photovoltaic cells (PV cells), or production of fuels such as ethanol from biomass (see alcohol as a fuel). A parameter sometimes used in renewable energy is the tonne of oil equivalent (toe). This is equal to 10,000 Mcal or 41,868 MJ of energy.\n\nIn a sense, renewable energy may be categorised as free energy, although most renewable energy sources would not normally be called "free energy". In engineering, free energy means an energy source available directly from the greater environment and which cannot be expected to be depletable by humans. Renewable energy development is concerned with the use of renewable energy sources by humans. For aspects of renewable energy use in modern societies see Renewable energy development. Modern interest in renewable energy development is linked to concerns about exhaustion of fossil fuels and environmental, social and political risks of extensive use of fossil fuels and nuclear energy.

biotechnology, the use of biological processes, as through the exploitation and manipulation of living organisms or biological systems, in the development or manufacture of a product or in the technological solution to a problem. As such, biotechnology is a general category that has applications in pharmacology, medicine, agriculture, and many other fields.\nThe techniques of genetic engineering have been used to manipulate the DNA (genetic material; see nucleic acid) of bacteria and other organisms to manufacture biological products such as drugs (insulin, interferon, and growth hormones). A common technique involved in this process in gene splicing, in which a gene that produces a desired product can be inserted into bacterial DNA. Bacteria can then be grown in large quantities and processed to extract the desired substance; specially cultured plant and animal cells can be similarly grown and processed. Hybrids of cancer and antibody-producing cells (hybridomas) have been cloned in the laboratory to mass produce experimental monoclonal antibodies, which are being studied for the treatment of cancer and other diseases. Bacteria have also been altered to break down oil slicks and industrial waste products.\n\nPlants and foods with such desired qualities as prolonged shelf life or increased resistance to diseases and pests have been created through genetic engineering; that is, by inserting DNA from other organisms. Much of the corn and soybeans grown in the United States, for example, are now genetically modified in some way, Livestock have also been genetically altered to produce medically useful substances (see pharming). The field of biotechnology also includes gene therapy, in which attempts are made to insert normal or genetically altered genes into cells to treat genetic disorders and chronic diseases.\n\nGreen biotechnology is biotechnology applied to agricultural processes. An example is the designing of an organism to grow under specific environmental conditions or in the presence (or absence) of certain agricultural chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby eliminating the need for external application of pesticides. An example of this would be Bt corn. Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate.

We can replace a lot of fossil fuels with methane energy. There's a town in the US which is almost totally run on methane gas from an intensive feedlot. If there was a will to do it there would be methane digesters and collectors on all sewerage systems and intensive farming installations.

Biodegradation\nBiodegradation is nature's way of recycling wastes, or breaking down organic matter into nutrients that can be used by other organisms. "Degradation" means decay, and the "bio-" prefix means that the decay is carried out by a huge assortment of bacteria, fungi, insects, worms, and other organisms that eat dead material and recycle it into new forms. \n\nIn nature, there is no waste because everything gets recycled. The waste products from one organism become the food for others, providing nutrients and energy while breaking down the waste organic matter. Some organic materials will break down much faster than others, but all will eventually decay.\nBy harnessing these natural forces of biodegradation, people can reduce wastes and clean up some types of environmental contaminants. Through composting, we accelerate natural biodegradation and convert organic wastes to a valuable resource. Wastewater treatment also accelerates natural forces of biodegradation. In this case the purpose is to break down organic matter so that it will not cause pollution problems when the water is released into the environment. Through bioremediation, microorganisms are used to clean up oil spills and other types of organic pollution. Composting and bioremediation provide many possibililites for student research. \n\n\n\nhttp://ei.cornell.edu/biodeg/\nhttp://en.wikipedia.org/wiki/Biodegradation\nhttp://www.glossary.oilfield.slb.com/Display.cfm?Term=biodegradation

Landfills will generate natural gas as the result of decomposition of the buried waste. My brother's first job was at a small power plant that burned gas collected from a network of pipes buried over an old landfill.\n\nHowever, there is a theory that much of the worlds natural gas is actually left over from the formation of the Earth and not of biological origin at all. I haven't heard much about that theory lately though, so it may be out of fashion.
