What is ecology? 

Most people believe that is the definition of ecological "built on the natural basis, using both natural and artificial means to create an environment conducive to living, comfort and health products", actually this is one-sided and does not give a clear definition. If we were to give a definition of science in ecological, that is, "the eco-Portal is formed using recycled materials, can not only reduce harm to human body, and can also reduce damage to the environment a healthy, green product."
