Review: Human Impact on Earth

Front

What is sustainable resource management?

Back

Sustainable resource management involves using natural resources in a way that meets current needs without compromising the ability of future generations to meet their own needs. An example is using policies for renewable energy, which can lower carbon emissions.

What is the impact of increased natural resource use on ecosystems?

Back

Increased use of natural resources can lead to habitat loss and decreased biodiversity, as seen in deforestation and species extinction.

Front

What defines unsustainable resource use?

Back

Unsustainable resource use occurs when resources are consumed faster than they can be replenished, leading to depletion and scarcity.

Front

How can we reduce human impact on Earth?

Back

Promoting energy efficiency and conservation is an evidence-based way to reduce human impact, as it leads to less energy use and lower emissions.

Front

What effect does a growing human population have on natural resources?

Back

A growing human population increases demand for natural resources, resulting in higher consumption and depletion.

Front

What is renewable energy?

Back

Renewable energy comes from sources that are naturally replenished, such as solar, wind, and hydroelectric power.

Front

What is non-renewable energy?

Back

Non-renewable energy comes from sources that cannot be replenished in a short time, such as fossil fuels like coal, oil, and natural gas.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species.

Front

What is habitat loss?

Back

Habitat loss occurs when natural environments are destroyed or altered, leading to a decline in species populations.

Front

What is carbon emissions?

Back

Carbon emissions are greenhouse gases released into the atmosphere, primarily from burning fossil fuels, which contribute to climate change.
