Out of agriculture, cities and civilizations grew, and because crops and animals could now be farmed to meet demand, the global population rocketed — from some five million people 10,000 years ago, to more than seven billion today.


What is the main objective of sustainable agriculture?

In sustainable agriculture, the goal is to reduce the input of external energy and to substitute non-renewable energy sources with renewable sources (e.g., solar and wind power, biofuels from agricultural waste, or, where economically feasible, animal or human labor).


How is agriculture dependent on oil?

Agriculture is almost entirely dependent on reliable supplies of oil for cultivation and for pumping water, and on gas for its fertilisers; in addition, for every calorie of energy used by agriculture itself, five more are used for processing, storage and distribution.


Why is the price of food going up in the years after the peak of oil?

Within a few years of Peak Oil occurring, the price of food will skyrocket because the cost of fertiliser will soar. The cost of storing (electricity) and transporting (gasoline) the food that is produced will also soar. Oil is required for a lot more than just food, medicine, and transportation.


What is oil used for?

Vast amounts of oil and gas are used as raw materials and energy in the manufacture of fertilisers and pesticides, and as cheap and readily available energy at all stages of food production: from planting, irrigation, feeding and harvesting, through to processing, distribution and packaging.


What are the benefits of organic production?

One of the benefits of organic production is that energy consumption and , therefore , fossil fuel consumption and greenhouse gas emissions, are less than that in conventional systems. The energy used in food production is separated into direct and indirect inputs.

What are the qualities of fossil fuels?

Certain qualities of fossil fuels are difficult to replicate, such as their energy density and their ability to provide very high heat. To decarbonize processes that rely on these qualities, you need low-carbon fuels that mimic the qualities of fossil fuels.


What is the most important gas in the world?

carbon dioxide. Carbon dioxide is gas released when carbon-containing fuels (biomass or fossil fuels) are burned. Carbon dioxide is the most important gas contributing to climate change. However, the advantages of fossil fuels come with a devastating downside.


Why is energy density important?

The energy density of fossil fuels is particularly important in the transportation sector. A vehicle needs to carry its fuel around as it travels, so the weight and volume of that fuel are key. Electric vehicles are a much-touted solution for replacing oil, but they are not perfect for all uses.


Why do people burn biomass?

People burned this biomass for heat and light. Plants provided food for people and animals, which, in turn, used their muscle power to do work. Even as humans learned to smelt metals and make glass, they fueled the process with charcoal made from wood.


How does fossil fuels affect the environment?

Fossil fuels are a natural resource. However, when burnt, they have a significant negative impact on the environment, and tackling climate change has become a top priority for governments across the world. Reducing the use of fossil fuels is seen as a crucial factor in the battle against the greenhouse effect, and global agreements have come into play to try to limit the world’s carbon footprint. The more carbon dioxide that is released into the atmosphere, the more the earth’s temperature increases. In turn, the Earth’s polar ice caps begin to shrink, while sea levels rise and weather becomes increasingly volatile. Climate change increases the likelihood of more extreme weather conditions like those witnessed over many recent years, such such as drastic floods, extreme fires, extended droughts, and intense heatwaves. The media covers climate change extensively, and the global weather shifts are a hot topic at international forums like the G20 summit, with the world convening to discuss ways to tackle climate change and reduce the usage of fossil fuels in favor of cleaner renewable energy sources.


Why are fossil fuel subsidies important?

While governments may argue that the main reason for giving subsidies to fossil fuel companies is to keep costs lower for consumers, many do not see this as justification for the sums of money spent by governments on fuel subsidies. Using subsidies to freeze fuel duties means that governments miss out on large sums of money that they would otherwise have received through the tax on fuel that could have been used on spending in other areas. Governments around the world have long debated the merits of the subsidy system, with the UK chancellor in 2018 strongly criticising the program and citing that the money lost due to fuel subsidies could have funded the entire staff of the United Kingdom’s National Health System twice over (Hammond, 2018). Meanwhile, other arguments against fuel subsidies suggest that it encourages wasteful energy consumption at a time when the world should be working on lowering their consumption of fossil fuels. According to the International Energy Agency (IEA), G20 leaders made progress towards phasing out subsidies at the 2009 summit. Agreeing to a plan to begin the reduction of fuel payouts with the consensus that subsidies were working against the efforts being made to tackle climate change, G20 leaders emphasized that subsidies would take investment away from the development of cleaner, renewable forms of energy. Although a medium-term plan was agreed upon, however, recent figures show that subsidies are in fact still prevalent. The IEA figures for 2018 show that fossil fuel subsidies have grown, rather than reduced, by as much as one-third, pushing subsidies in excess of $400 billion.
