-It may be too expensive to solve the problems
-Legislation would be too complex
-Government are more concerned about development than the people
-Government do not want to risk businesses moving out
-Corruption likley
Explain how economic activities are causing global warming.
-Carbon dioxide and other greenhouse gases are given off by burning fossil fuels, industry and pastoral farming

-Soil washed away
Suggest in ways in which both economic activities and natural processes may cause soil erosion.
-Deforestation
-Grazing by animals removing vegetation cover, especially if herds are too large
-Over-cultivation removes nutrients from soil, destroying structure of soil
-Ploughing leaves soil bare

Identify two ways in which the transport of the manufactured product may damage the natural environment.
-Emissions
-Uses energy
-Noise pollution from vehicles
-Deforestations for road buildings
-Increased roadkill
Suggest three ways in which the environmental impacts of producing and transporting this manufactures product could be reduced.
-Use less packaging
-Transport materials in bulk
-Produce raw materials close to factory
-Use renewable energy sources
-Catalytic converters
-Conserve energy in factory
Explain how greenhouse gas emissions may cause an increase in global temperatures
-Buildup in atmosphere
-Let sun's rays through
-Bounces/reflects from earth's surface
-Do not allow heat to escape
-Insulates/acts like a greenhouse
Explain why in many countries only small amounts of alternative energy sources are used.
-Few alternative energy sources are available or potentially available
-Some in early stages of development
-Limited technology in many areas
-Expense of development
-Much of industry geared up to using fossil fuels

-Development seen as more important than the natural environment
-Need for transport as part of everyday life
-Burning fuels is vital to provide energy
-Need for international collaboration
-Governments have other priorities
-People don't know/don't care
Describe the strategies which can be used to reduce carbon dioxide levels in the atmosphere.
-Use of alternative energy supplies such as HEP/wind/solar, so less fossil fuels are used
