Review For Environmental Science

Front

What is biomass?

Back

Biomass is organic material that comes from plants and animals. It is considered a renewable energy source because it can be replenished through natural processes like plant growth.

Front

What are the key factors contributing to biodiversity loss?

Back

Key factors include habitat destruction, climate change, pollution, overexploitation of species (e.g., overfishing or hunting), and invasive species.

Front

How can human populations reduce their ecological footprint?

Back

Humans can reduce their ecological footprint by adopting sustainable practices such as conserving water and energy, using renewable resources, reducing waste and consumption, and supporting sustainable agriculture and transportation systems.

Front

What causes urban heat islands?

Back

Urban heat islands are caused by the lack of vegetation, which helps cool down the environment.

Front

What are the consequences of overfishing on marine ecosystems?

Back

Overfishing hurts fish populations, disrupts food webs, and reduces biodiversity in marine ecosystems.

Front

Define ecological footprint.

Back

An ecological footprint measures the environmental impact of an individual or population, expressed as the amount of land and water area required to produce the resources consumed and to absorb the waste generated.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitat is rendered unable to support the species present, leading to a decline in biodiversity.

Front

Explain the concept of sustainable agriculture.

Back

Sustainable agriculture is farming that meets current food needs without compromising the ability of future generations to meet their own needs, focusing on environmental health, economic profitability, and social equity.

Front

What role do invasive species play in ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, leading to declines in biodiversity and altering habitat structure.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily driven by human activities such as burning fossil fuels.
