Threats to biodiversity

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What are the main threats to biodiversity?

Back

The main threats to biodiversity include habitat destruction, climate change, pollution, invasive species, and overexploitation of resources.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process of breaking up large habitats into smaller, isolated patches, which can negatively impact species survival and ecosystem health.

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can outcompete native species for resources and disrupt local ecosystems.

Front

How does climate change affect biodiversity?

Back

Climate change can alter habitats, shift species distributions, and increase the frequency of extreme weather events, all of which can threaten biodiversity.

Front

What is the role of conservation in protecting biodiversity?

Back

Conservation involves the protection and management of natural resources and habitats to preserve biodiversity and prevent species extinction.

Front

What is overexploitation?

Back

Overexploitation refers to the unsustainable use of natural resources, such as overfishing or excessive logging, leading to population declines and habitat loss.

Front

What is pollution and how does it threaten biodiversity?

Back

Pollution introduces harmful substances into the environment, which can degrade habitats, harm wildlife, and disrupt ecosystems.

Front

What is the significance of keystone species?

Back

Keystone species are crucial for maintaining the structure of an ecosystem; their removal can lead to significant changes and loss of biodiversity.

Front

What is the difference between endangered and extinct species?

Back

Endangered species are at risk of extinction in the near future, while extinct species no longer exist anywhere on Earth.
