Agriculture
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture by humans dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies; industrial agriculture based on large-scale monoculture farming has become the dominant agricultural method.
Algae fuel
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. Several companies and government agencies are funding efforts to reduce capital and operating costs and make algae fuel production commercially viable. Like fossil fuel, algae fuel releases when burnt, but unlike fossil fuel, algae fuel and other biofuels only release recently removed from the atmosphere via photosynthesis as the algae or plant grew.
Food vs. fuel
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views, and is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is causing it, and what can or should be done to remedy the situation. This complexity and uncertainty is due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts vary in the short and long terms, and involve delayed effects.
Biofuel
A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials).
Hemp
Hemp, or industrial hemp (from Old English "hænep"), typically found in the northern hemisphere, is a variety of the "Cannabis sativa" plant species that is grown specifically for the industrial uses of its derived products. It is one of the fastest growing plants and was one of the first plants to be spun into usable fiber 10,000 years ago. It can be refined into a variety of commercial items including paper, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. Although cannabis as a drug and industrial hemp both derive from the species "Cannabis sativa" and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.
Ethanol fuel in Brazil
Brazil is the world's second largest producer of ethanol fuel. Brazil and the United States led the industrial production of ethanol fuel in 2014, together accounting for 83.4 percent of the world's production. In 2014 Brazil produced 23.4 billion liters (6.19 billion U.S. liquid gallons), representing 25.2 percent of the world's total ethanol used as fuel. Brazil is considered to have the world's first sustainable biofuels economy and the biofuel industry leader, a policy model for other countries; and its sugarcane ethanol "the most successful alternative fuel to date." However, some authors consider that the successful Brazilian ethanol model is sustainable only in Brazil due to its advanced agri-industrial technology and its enormous amount of arable land available; while according to other authors it is a solution only for some countries in the tropical zone of Latin America, the Caribbean, and Africa.
Effects of global warming on human health
The effects of global warming include its gayon human health. The observed and projected increased frequency and severity of climate related impacts will further exacerbate the effects on human health. This article describes some of those effects on individuals and populations. A good example of the impact of global warming on health can be seen in the disease Erythromelalgia. This is a vascular disease that is commonly triggered by the involvement of change in temperature, which leads to syndromes including (first and second degree) burning pain, increased temperature, erythema and swelling, of mainly the hands and feet that are affected.
