1. To determine which of the options would be most likely to lead to increased biodiversity, we need to consider the impact of each option on ecosystems and species.
- Clear cutting involves removing all trees in an area, which leads to the destruction of habitats and can result in decreased biodiversity. So, clear cutting is not likely to lead to increased biodiversity.
- Oil drilling can have significant negative environmental impacts, such as pollution and habitat destruction, which can harm species and reduce biodiversity. Therefore, oil drilling is not likely to lead to increased biodiversity.
- National Park Planning involves establishing protected areas, conserving habitats, and implementing measures to protect wildlife. This option aims to preserve natural ecosystems and promote biodiversity. Therefore, national park planning is the most likely option to lead to increased biodiversity.
- Farming can have varying impacts on biodiversity, depending on the farming practices. Certain agricultural practices, such as monoculture and excessive use of pesticides, can harm biodiversity. However, sustainable and organic farming practices can promote biodiversity. Without further information, it is difficult to determine the impact of farming on biodiversity in this question.
2. The scenario described here, where a wetland is drained to make way for a housing development, is an example of habitat destruction. Habitat destruction occurs when natural habitats, such as wetlands, forests, or grasslands, are significantly altered or destroyed, leading to the loss of habitat for the species that rely on those ecosystems.
3. The image showing a wildlife corridor indicates a structure that helps prevent habitat fragmentation. Habitat fragmentation occurs when large, continuous habitats are divided into smaller, isolated fragments. This can disrupt ecological processes, disrupt migration patterns, and limit the gene flow between populations, ultimately impacting biodiversity. Wildlife corridors aim to provide connections between fragmented habitats, allowing species to move between them and reducing the negative effects of habitat fragmentation.
4. Liners are laid down at the bottom of a landfill before waste is deposited to prevent hazardous substances in the trash from leaking into groundwater. These liners act as a barrier, preventing liquids from leaching out and contaminating the surrounding soil and groundwater. By preventing the leakage of hazardous substances, these liners help protect the environment and ensure the proper management of waste in landfills.
