for the last two years, i have been overwhelmed by the changes in our living environment. every time i go surfing or walk my dog on the beach, it’s really sad to see ocean getting trashed like a dump, down to every time i have to spend an hour or two picking up garbage on the beach. it was just one of those small environmental changes that happened around me. and i was shocked when i saw the high-resolution satellite images of the earth sent to me by elon and anthony. the colorful earth we had in mind was dimmed and riddled with holes in the galaxy. so i decided to make more new changes to my life and business environment. the task can be something i absolutely not easy, and yet i will put forth my effort to help make things better. we're also spending more on green technology and environmental protection and medical research and development. you'll also find that i spend more time in nature and the ocean than in the metropolis made of armored concrete. meanwhile, i hope that we can understand the importance of protecting the earth and the environment through a series of environmental disasters over the past few years, including storms, tsunamis, haze, fires, pests, viruses and plagues brought by climate warming. the whole ecological balance of the earth is changing. massive destruction of environment has brought about negative effects and even poses a great threat to man's existence. the earth we abuse and the living things we k**l will, in the end, take their revenge; for in exploiting their presence we are diminishing our future. as the dominant species on earth, it is our responsibility to use that position wisely and destroy as little as possible while still assuring the survival of mankind. the protection of biodiversity is one of the key measures to protect the earth, the ecological system, wild animal and plant resource, and the human survival environment. only there was only common humanity to unite and care for the earth to protect our survival, then we will not destroy their homes. let's start it from ourselves, our family, our friends and other people around us. let us all compose up from at our sides to protect our homeland- the earth.
