Why are many species of animals and birds getting extinct?

The extinction of animals and birds happens when a species disappears completely from the Earth. This is a serious problem caused by human activities and environmental changes.

1. Habitat Destruction

• Cutting down forests, draining wetlands, and urban expansion destroy the natural homes of animals and birds.
• Example: Tigers lose their forest homes, birds lose nesting trees.

2. Pollution

• Air, water, and soil pollution affect the health and survival of wildlife.
• Example: Chemicals in rivers can kill fish and birds that feed on them.

3. Hunting and Poaching

• Animals and birds are hunted for meat, skins, feathers, horns, or body parts.
• Example: Tigers, elephants, and rhinoceroses are poached for their valuable parts.

4. Climate Change

• Global warming, changing rainfall patterns, and rising temperatures affect habitats and food sources.
• Example: Polar bears struggle as ice melts in the Arctic.

5. Introduction of Invasive Species

• Non-native animals or plants brought by humans compete with local species for food and habitat.
• Example: Invasive snakes, fishes, or plants can destroy local wildlife.

6. Overexploitation

• Overfishing, excessive logging, and large-scale farming reduce the resources that wildlife needs.
