Dominic Okachi's post on Goodwall - Sustainability development is a development that meet the needs of the present without compromising the ability of the future generation to meet their own needs. It is however generally agreed that a sustainability favors conditions that benefits the environment, the economy and the society without compromising the welfare of the future generations. The basic definition of sustainability has been expended to include three major pillars (often referred to as the three Es). Social Equity: Relates to conditions favoring a distribution based upon comparative levels of productivity. Economy Efficiency: Concerns conditions permitting higher levels of economic efficiency in terms of resources and labor usage. Environmental Responsibility: Involves a “footprint” which is lesser than the capacity of the environment to accommodate. This includes the supply of resources (foods, water, energy etc.), but also the, safe disposal of numerous forms of wastes. The following are the proposed solutions to climate change: Bio char: A way of trapping with “green coal”. Any biomass waste - from wood to peanut shells – releases carbon as it decomposes. But it can be burned in a kiln by pyrolysis (an airless burning technique) to create bio-char, also known by the sobriquet green coal. Planting of trees (afforestation) to trap/absorb carbon dioxide and reduce direct sun radiation on living things. Fertilizing the ocean: Dumping iron dust into the ocean to remove carbon. Hydrogen Cargo Freight: Emissions free shipping. To produce hydrogen – hybrid boats that could turn global freight from an emissions juggernaut into a zero – emissions guide across air freight. Backyard Sufficiency: Treating your garden as a source of protein. Also known as Micro Eco Farming, backyard sufficiency is about exploiting small (and often unpromising) plots of urban land until they yield a bumper harvest. Strategic Organic: Organic pick ‘n’ mix. Organic production has lots of eco-merits, but the thing that made organics the darling of the shopping trolley was the fact their production ruled out pesticides. Alternative Fuels for Sustainability: The main purpose of fuel is to store energy, which should be in a stable form and can be easily transported to the place of use. Thus, the following are alternative fuels for a sustainable generation/future: Biofuel: Biofuels are also considered a renewable source. Although renewable energy is used mostly to generate electricity, it is often assumed that some form of renewable energy or a percentage is used to create alternative fuels. Algae – based fuels: Algae – based bio-fuels have been promoted in the media as a potential panacea to crude oil based transportation problems. Bio-diesel: Bio-diesel is made from animal fats or vegetable oils, renewable resources that come from plant such as atrophy, soya bean, sunflowers, corn, olives, peanuts, palm, coconut, etc. once these fats or oils are filtered from their hydrocarbons and then combined with alcohol like methanol, diesel is brought to life. Alcohol fuels: Methanol and ethanol fuels are primary sources of energy, they are convenient fuels for storing and transporting energy. Compressed Air: The air engine is an emission free piston engine using compressed air as fuel. Unlike hydrogen, compressed air is about one – tenth as expensive as fossil fuel, making it an economically attractive fuel.
