Question

Describe two possible impacts of urbanisation on the world’s biospheres.

Answer 1

Urbanisation impacts the world's biospheres by causing loss of biodiversity due to habitat destruction and leading to environmental degradation and climate change as demands for urban infrastructure increase.

Step-by-step explanation:

Urbanisation can have significant impacts on the world's biospheres, affecting both biodiversity and human societies. Two possible impacts include:

1. The loss of biodiversity as natural habitats are replaced by urban infrastructure. Urban areas can lead to the disappearance of native species and ecosystems. This habitat destruction reduces plant and animal diversity and disturbs ecological balances.
2. Changes in resource use and environmental degradation. The demands of urban populations lead to increased pollution and alteration of natural landscapes. Urban sprawl often requires more land for housing and infrastructure, leading to deforestation and increased greenhouse gas emissions, thereby contributing to climate change.

In both cases, the once 'natural' environments are increasingly difficult to find, as the human footprint expands into even the most remote of regions.
