Sub-Strand: S.8.1.3.1 BIODIVERSITY, CHANGE AND SUSTAINABILITY

Endangered and endemic species in your area

Human Activity and its Impact on Species

• All living things, including humans, impact the environment.

Negative Human Impacts on the Environment

1. Water and Land Pollution

1. Water is essential for survival, but its availability is often overlooked.
2. Land pollution occurs due to human activities and misuse of natural resources.
3. Causes of Land Pollution and Degradation

2. Urban Sprawl: Natural habitats are destroyed for development, often wastefully.
3. Poor Agricultural Practices:
   • Chemical fertilizers, pesticides, and herbicides harm the environment.
   • Animal manure runoff pollutes water.
   • Monoculture farming (growing the same crop repeatedly) depletes soil nutrients.
   • Deforestation for farming damages ecosystems.
4. Personal Consumption:
   • Excessive demand for goods leads to overuse of natural resources.
   • Mining and industrial activities pollute land and water.
5. Industrial Activities:
   • Factories produce harmful chemicals and excessive waste.
   • Unethical practices like illegal dumping increase pollution.
6. Overproduction of Synthetic Materials:
   • Plastics and metals take a long time to break down, causing pollution.

Why We Should Save Endangered and Endemic Species

1. Keeps Nature Balanced – Every species is important in the food chain.
2. Protects Our Environment – Healthy animals and plants help keep air, water, and soil clean.
3. Helps Science and Medicine – Many plants and animals can be used for medicine and research.
4. Supports Jobs and Tourism – People visit places to see wildlife, which helps the economy.
5. It’s Our Responsibility – We must protect nature for future generations.
6. Stops Bigger Problems – Losing one species can harm others, causing an imbalance.
7. Helps Control Climate – Trees and animals help keep the weather stable.
