World Biomes Overview - Geography

Environmental Consequences

• Changes to the natural environment can lead to a loss of biodiversity.
• Threats to food security do not include increased access to fresh water.
• Changes to soil can be influenced by deforestation.
• Wearing out soil commonly results in reduced crop yields.
• Climate change can directly impact food security through extreme weather events.
• One major consequence of rising global temperatures is sea level rise.
• Land use for purposes other than agriculture can impact food security by reducing arable land.
• Sustainable agricultural production relies on effective land management practices.
• Climate change affecting ecosystems is indicated by changes in plant and animal distributions.
• Climate change can affect agricultural production by altering growing seasons and increasing pest and disease outbreaks.

Principles of Government

• Separation of powers is the principle ensuring no single branch of government has too much power.
• Equality before the law ensures that laws are applied equally to everyone.
• Due process of law is specifically tied to fairness in judicial processes.
• Checks and balances is primarily associated with legislative mechanisms and distribution of function among government branches.
• Limited government is not a principle of democratic governance.

Biomes and Environmental Factors

• Boreal forests are characterized by long, cold winters and short summers.
• Population density is not directly related to food production.
• Tropical rainforests usually have the warmest climate.
• Irrigation positively impacts food production by providing water to crops in dry areas.
• Fertilizers primarily impact agriculture by increasing soil nutrient levels.
• Overgrazing can negatively affect food productivity.
• Biodiversity is critical for sustaining healthy forest ecosystems.
• Climate conditions play a role in food production by determining growing seasons, precipitation, and temperature.
