Q:

How do humans affect the carbon cycle?

A:

Humans affect the carbon cycle through the exhalation of carbon dioxide, the burning of fossil fuels, deforestation and other poor agricultural practices. Burning fossil fuels and deforestation leads to a disruption in the balance of the carbon cycle.

The natural amount of carbon dioxide exhaled by humans is utilized in the carbon cycle by vegetation to produce oxygen. When a surplus of fossil fuels are burned, a large amount of carbon dioxide is released into the air. Deforestation reduces the amount of vegetation that can reduce the atmosphere's carbon dioxide levels and creates less habitable soil for new growth. Carbon dioxide builds up due to the overuse of fossil fuels and an increasing lack of vegetation.

    Why is the carbon cycle important?

    A:

    The carbon cycle is important because all living things are made of carbon in one way or another. The carbon cycle is how carbon is exchanged throughout the earth: between the atmosphere, oceans, ecosystem and geosphere. If the carbon cycle fails, then life begins to break down, causing life to end.

    How do humans affect the water cycle?

    A:

    According to the National Aeronautics and Space Administration’s Goddard Institute for Space Studies, humans alter the planet’s water cycle by changing stream flow patterns. These changes cause the alteration of the sea level and ocean salinity, as well as altering the land’s physical properties. Left unchecked, such disruptions could play a part in changing the planet’s climate.

    How do humans affect the nitrogen cycle?

    A:

    Humans affect the nitrogen cycle through activities that increase the amount of nitrogen that is biologically available in an ecosystem. The major culprits are fossil fuel combustion and the application of nitrogen-based fertilizer. Fossil fuel combustion releases nitric oxides and combines with other elements in the air to form smog and acid rain.

    How do natural environments affect human actions?

    A:

    Natural environments are a major influence on where humans live, socialize, harvest resources and travel. The most influential aspects of a natural environment include climate, landforms, soil characteristics and proximity to water. Another important factor is the presence or suspected presence of natural resources such as metals, fossil fuels and gemstones.
