What are the advantages of taking an ecosystem approach to conserving biodiversity?
Explain the benefits of taking an ecosystem approach, as opposed to a single species approach, to conserving biodiversity. The ecosystem approach sets asides protected areas as a mean of conserving biodiversity whereas the single-species approach is focused primarily on increasing the abundance of a particular species.
Why is ecosystem diversity important?
Ecosystem diversity boosts the availability of oxygen through photosynthesis among plant organisms living in a certain habitat. For instance, in an aquatic environment, once species are diverse it helps in water purification which is processed by plant varieties for it to be used by humans.
Which of the reasons for preserving biodiversity do you think would be the most likely to convince people that biodiversity should be preserved?
Ecosystem Productivity One of the main reasons we should continue to focus on preserving biodiversity is that it helps to boost ecosystem productivity. A proper functioning ecosystem is going to be naturally more resistant to harsh environmental conditions like climate change.
What is the ecosystem approach to preserving biodiversity?
The ecosystem approach is a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. Application of the ecosystem approach will help to reach a balance of the three objectives of the Convention.
What are two arguments in favor of biodiversity?
Arguments for biodiversity conservation There are five types of argument for biodiversity conservation: economic, indirect economic (protection against epidemic pathogens), ecological and aesthetic/ethical (Ehrenfeld, 1988; Ehrlich and Ehrlich, 1992).
How can we preserve biodiversity?
Biodiversity can be conserved by:
- Preventing the cutting of trees.
- Putting a ban on hunting of animals.
- Efficient utilisation of natural resources.
- Protected areas should be developed for animals where no human activities are allowed.
What are the reasons why biodiversity should be preserved?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Why should we preserve biodiversity?
Biodiversity conservation protects plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.
What is an ecosystem based approach?
Ecosystem-based management is an environmental management approach that recognizes the full array of interactions within an ecosystem, including humans, rather than considering single issues, species, or ecosystem services in isolation.
What is meant by an ecological approach?
The ecological approach is a framework for studying the behavior of animals in their environments. They must acquire the ability to flexibly guide their behavior from moment to moment in the midst of developmental changes in their bodies, brains, skills, and environments.
Why is it important to preserve biodiversity in the world?
One of the main reasons we should continue to focus on preserving biodiversity is that it helps to boost ecosystem productivity. A proper functioning ecosystem is going to be naturally more resistant to harsh environmental conditions like climate change. A prime example is when an area is deforested of large amounts of fully grown trees.
Why is it important to protect the environment?
Another great reason why we should continue focusing on preserving biodiversity is the importance of natural beauty. There are many historical sites all across the nation like the redwood forest that need to be protected to preserve their status for future generations to enjoy.
How are trees important to a healthy ecosystem?
In a healthy ecosystem, carbon and organic waste materials are often captured by trees and recycled naturally. Unfortunately, environmental stress is disrupting this natural process. Forests typically soak up as much as 2.4 billion metric tons of carbon each year.
How does reducing forest area affect the number of species?
Figure 3 shows that reducing forest area from 100 km 2 to 10 km 2, a decline of 90 percent, reduces the number of species by about 50 percent. Species–area estimates have led to estimates of present-day species extinction rates of about 1000 E/MSY and higher.
