4.7.3.6 Maintaining Biodiversity Flashcards
1
Q
What are positive human interactions with ecosystems?
A
- maintaining rainforests to ensure habitats are safe
- reducing water pollution and monitoring changes
- preserving areas of scientific interest by stopping humans going there
- replanting hedgerows and woodlands to provide habitats which were previously destroyed
2
Q
What are negative human interactions with ecosystems?
A
- production of greenhouse gases leading to global warming
- producing sulfur dioxide in factories which leads to acid rain and affecting habitats
- chemicals used in farming leak into environment
- clearing land in order to build on, reducing habitats
3
Q
What have scientists and concerned citizens put into place and why?
A
- programmes to reduce the negative effects of humans on ecosystems and biodiversity
4
Q
What are examples of the programmes put into place?
A
- breeding programmes
-protection of rare habitats - reintroduction of hedgerows and field margins where one type of crop is grown
- reduction of deforestation and carbon dioxide production
- recycling
5
Q
What do the breeding programmes help stop?
A
- endangered species from becoming extinct
6
Q
What does the protection of rare habitats help stop?
A
- species here from becoming extinct
- if damaged, they may be regenerated to encourage populations to live here
7
Q
What does the reintroduction of hedgerows and field margins around land where only one type of crop is grown help maintain?
A
- biodiversity as hedgerows provide a habitat and field margins provide areas where wild flowers and grasses can grow
8
Q
What does the reduction of deforestation and carbon dioxide production help reduce?
A
- rate of global warming
- slows down rate that habitats are destroyed
9
Q
What does recycling rather than dumping waste in landfill help reduce?
A
- amount of land taken up for landfills
- slows rate we are using up natural resources
