In my opinion, both human and animals needs are important. Nowadays, ecological diversity is facing different issues, such as global warming and overfishing which may affect the living environment of animals. These problems become more noticable with the advancement of human development. How to balance between human and animals needs is a controversial topic. Some people think that it is essential to prioritize the value of environmental friendly in the toppest place as human also be included in the ecology. However, it is really need to pick a choice between human and animals? If we can have a better land management for filfulling the requirement of both human and animals, we can make a balance in the human development and environment. therefore, i do not agree that human needs for farmland, housing and industry are more significant than saving land for endangered animals, both choices can co-exist.
