General Resources
Water
Overview
Water is needed for many things including humans, agriculture and energy. But not everywhere has water or needs water
Rainfall
In general most of the rainfall in the uk falls in the north west of britain, such as glasgow. An oddity is birmingham which has less waterfall but is in the west.
Water Demands
Demand for water is increasing because wealth is increasing so so is the number of appliances, more agriculture, larger industry and more population.
Defecit and surplus
Water defecit is when a place has less water than the people need whereas surplus is when a place has more water than people need it. In some places of deficit they have economic water scarcity which means they dont have the money for the water. Physical water scarcity is when the country has the money but not enough water to supply it. Water tranfer schemes take water from areas of water deficit to surplus.
Pollution and managment
Water pollution destroys ecosystems, spreads diseases, cannot be used for drinking or cleaning, kills wildlife and raises pH of water and kills plants. We manage this by restricting farmers and industry from putting too much waste into rivers, we could use treatment plants, educate people on the dangers and investing in infrastructure to make new sewage lines
Grey and reclaimed water
Reclaimed water is grey water that has come from baths, dishwashers and washing machines. This is reused for thing like irrigating crops, industry, drinking, topping up rivers and to recharge water aquifers.
Energy
Demand
The demand is changing due to appliances being much more energy efficient and the decline of industrial. But there has been an increase in air travel due to more cars and planes
Energy Mix
Coal
Coal is a fossil fuel and has the largest reserves in in Britain. It is expected to run out by 2091 and many mines are still available. Advantages of coal is that it creates jobs but it also causes great climate change. Miners also suffer diseases which incurs a cost to the health service. Much of the coal is also in hard-to-access areas which is expensive to mine.
Renewable
Renewable energy is energy that can be used again and again. This includes waves, sun, wind, the tides and geothermal heat to produce energy. The problems with renewable is the cost which is expensive and that it only produces small amount of energy.
Disadvantages include its low profit the impact on the environment. It is good it produces lower carbon emissions and can support wildlife
Nuclear
Nuclear is classified as non-renewable due to uranium being a finite resource. nuclear is bad because it is very expensive to make reactors and maintain them.Also waste has to be stored for many years before it becomes usable. Also the environment gets hurt if the radiation is released.
Oil
A fossil fuel and take so long to replace that they are labelled as non-renewable. Most oil is fount in the Scottish territorial waters in the uk and this boosts local economies such as aberdeen. Oil is the least quantity and should run out by 2051. A disadvantage is fracking as this leads to earthquakes and economic damage. Oil pipelines take up space too
Gas
Gas is also a fossil fuel and there are also reserves found in the north sea. We are slowly losing are gas reserves so we are relying on imports from other countries. This creates greenhouse gases which harm the environment. Our reserves should run out by 2061

UK carbon footprint
Food travels over 30 billion km per year, makes up 17% of the uk's carbon footprint
Kenya food facts
Kenya prepares 350 tonnes of food ach night. In 1998 the uk imported 3800 tonnes of vegetables and legumes.
Agribusiness
Treating farming like an industrial business , uses chemicals and mechanisation
Seasonal Food
Before supermarkets only seasonal food was eaten but now a lot of food we can not grow here is imported
Local sourcing
Reduces CO2 emissions by eating seasonal, local, homegrown food.
