7.3.6 Maintaining Biodiversity

What is the aim of breeding programs in conservation?

To stop endangered species from becoming extinct.

Why is protection of rare habitats important for biodiversity?

To prevent rare species from becoming extinct and encourage regeneration so populations can live there again.

How does reintroducing hedgerows and field margins help biodiversity?

They provide habitats for many organisms, as fields with one crop alone would not support as many species.

Give an example of a positive human interaction with ecosystems.

Maintaining rainforests to ensure habitats are not destroyed.

Give another example of a positive human interaction with ecosystems.

Reducing water pollution and monitoring changes over time.

Give a third example of a positive human interaction with ecosystems.

Preserving scientific areas by preventing human interference.

Give a fourth example of a positive human interaction with ecosystems.

Replanting hedgerows and woodlands to restore lost habitats.

Give an example of a negative human interaction with ecosystems.

Producing greenhouse gases, leading to global warming.

Give another example of a negative human interaction with ecosystems.

Producing sulfur dioxide in factories, causing acid rain and harming habitats.

Give a third example of a negative human interaction with ecosystems.

Chemicals from farming leaking into the environment.

Give a fourth example of a negative human interaction with ecosystems.

Clearing land to build on, which reduces habitats.
