The end of the mankind. Good afternoon from Mexico City. I hope you can understand my proposal, because not all of us pay attention to what is really happening. We humans have generated climate change, because we are a plague. Every day 372,960 people are born in the world and only 155,520 die. So we have 217,440 more people on the planet every day, never less. So exponential growth will always go up. My proposal is the following. A worldwide advertising campaign explaining what is happening all over the planet and inviting the world population to plan the births of their children, following a reproduction calendar. For example: Year 2022 with births, years 2023 and 2024 without births. Year 2025 with births, years 2026 and 2027 without births, year 2028 with births, years 2029 and 2030 without births. So, consecutively. Please do your own calculations and graphs, and you will realize that in this way, the exponential growth graph will flatten and we will begin to see the reduction of population in the world, without killing anyone, without wars or mysterious viruses that try get the same. It may seem impossible to you, but covid19 taught us that a message can reach the last corner of the planet and that it is possible to flatten an exponential growth graph, with distancing. Covid19 with social distancing, and the human plague separating births with a calendar. I hope you can understand the importance of my proposal.
