FAQs on Class 8 Science Chapter 5 Question Answers - Conservation of Plants and Animals
| 1. What is conservation and why is it important? |  |
Ans. Conservation is the act of protecting and preserving natural resources such as plants, animals, and their habitats. Conservation is important because it helps to maintain biodiversity, which is essential for the survival of all living organisms. It also helps to prevent the extinction of endangered species and ensures the sustainability of natural resources for future generations.
| 2. What are the major threats to plant and animal conservation? | |
Ans. The major threats to plant and animal conservation include habitat loss, climate change, poaching, pollution, and invasive species. Habitat loss is caused by deforestation, urbanization, and agriculture. Climate change is causing changes in temperature, rainfall patterns, and sea levels, which can affect the habitats of plants and animals. Poaching and illegal trade of wildlife can lead to the extinction of species. Pollution can harm the natural environment and the organisms that live in it. Invasive species can outcompete native species for resources and disrupt the natural ecosystem.

Protected areas are designated areas that limit human activities to protect biodiversity. Wildlife corridors connect fragmented habitats to allow animals to move freely. Captive breeding programs breed endangered species in captivity to increase their population. Habitat restoration involves restoring degraded habitats to their original state. Public awareness campaigns educate people about the importance of conservation and how they can contribute to it.
| 4. How can individuals contribute to plant and animal conservation? | |

Individuals can contribute to plant and animal conservation by reducing their carbon footprint, supporting conservation organizations, volunteering for conservation activities, avoiding buying products made from endangered species, and spreading awareness about conservation.

Creating protected areas such as national parks and wildlife sanctuaries can help to preserve biodiversity. Governments can also fund conservation efforts and provide incentives for individuals and organizations to contribute to conservation.
