Protect our ecosystem

Ecosystem is a unified whole formed as they

continuously exchange material and energy in a particular environment that between a variety of biological communities and the environment, as well as among themselves. The number of ecosystem types is large, generally can be divided into natural ecosystem and artificial ecosystem. The largest ecosystem is the biosphere; the most complex ecosystems is the tropical rainforest ecosystem, Humans mainly live in artificial ecosystem basing with city and farmland. Ecosystems are open , in order to maintain its own stability, ecosystems require constant energy, otherwise there is a danger of collapse; With the improvement of productivity, the interference of human activities on ecosystems increases, the human destruction on ecological system has been unprecedented since the industrial revolution, while the twentieth century, after the sixties, the reconstruction and rehabilitation of ecosystems have become an important issue, Ecosystem is the basic condition of human existence，it is our common responsibility that protecting ecosystems!

The key to protection of the Eco-system stability is

to protect biodiversity. Measures taken include:

1. Local conservation: in order to protect biological diversity, we can protect and manage a certain area of land or water including the objects protected.

2. Migration conservation: in order to protect biological diversity, we should move out the species that suffer from a serious threat to the survival and reproduction because of the living conditions no longer exist, the number of species is rare or difficultly find a spouse and other reasons, move them into the zoo, botanical garden, aquarium and endangered animal breeding center, give them special protection and management.

3. Establish gene banks: in order to protect biological diversity, people have started a new plan to achieve the desire to saving species by the establishment of gene banks.

4. In order to ensure the smoothness and efficiency of the conservation of biological diversity, we must use legal means, improve relevant legal systems: firstly, complement nature preservation zone system, clear-cut the establishment and management systems of preservation zone. Secondly, establish a strict system to control alien species invasion. Lastly, establish a fund system, in order to effectively

conserve biological diversity, we must have a strong economic base.
