Why We Should Protect Animals
Animals are our friends and companions. They share the same planet with us and make our lives more colorful and interesting. However, many animals are facing the danger of extinction because of human activities. Therefore, we should protect animals for the following reasons.
First of all, animals are part of the natural ecosystem and biodiversity. They play important roles in maintaining the balance of nature and providing various services for humans, such as pollination, pest control, soil formation, water purification and so on. If we lose animals, we may also lose many benefits that they bring to us.
Secondly, animals are sources of knowledge and beauty. They have different shapes, colors, behaviors and abilities that can inspire us to learn more about the world and ourselves. They can also enrich our culture and art with their unique features and expressions. By protecting animals, we can preserve the diversity and richness of life on earth.
Thirdly, animals have intrinsic value and rights. They are not just objects or resources for humans to use or abuse. They have feelings, emotions and intelligence that deserve our respect and care. They have the right to live freely and happily in their natural habitats without being harmed or exploited by humans.
In conclusion, we should protect animals because they are valuable and irreplaceable for us and themselves. We should respect their existence and coexist with them peacefully. We should also take actions to reduce our negative impacts on their environment and welfare. By doing so, we can not only protect animals, but also protect ourselves and our future.
