ie we make stuff that we never use. It just gets thrown out as waste!
Resources: soil Gives support and nutrients to crops Eroded and blown away by wind Absorbs water, so helps to slow down or stop the risk of flooding Over use by people and/or animals can cause lasting damage to soils Soaks up some harmful chemicals Washed away by heavy rains
Resources: coal, oil, gas and minerals China & India Are Building 4 New Coal Power Plants – Every Week More than 1,000 new coal plants are planned worldwide, with about three-quarters of these in China and India alone Coal, oil and gas are Fossil Fuels. We dig up coal and drill for oil. We then burn the coal and oil (and gas) to generate electricity
Resources: seas and oceans 70 % of the Earth’s surface is water To think about: What do you think will be the impact of these types of fishing on the resources of the sea?
