Program # 2 Projects

Systems to Reduce and Absorb CO2 Emissions, Purify the Air and Water of the Cities, the Atmosphere and the Oceans


To solve climate change we need to absorb and reduce CO2 emissions, improve air quality and prevent viruses from collapsing development. Reduce pollution both in the atmosphere and in the oceans and preserve ecosystems, based on key elements, such as bees and butterflies, so that the planet can preserve life as we know it now, solve water scarcity, hunger and poverty, in short, to improve the quality of life of humanity and ecosystems.



This program promotes projects for the development of various technologies that work together with nature, to improve virus-free outdoor and indoor air quality, without contaminating water and soil, and save the oceans through biomimetic technologies, which absorb CO2 and release oxygen, purify the atmosphere, and can mitigate toxic, bioweapon, and chemical gases.

We discover how to make the integration of nature into cities profitable, with the functionality of generating and storing renewable energy and clean water.  


In this program, the projects are oriented to develop the components of sustainable urban and rural areas, without pollution, that contribute to the solution of global warming, achieve the total reuse of waste, save the oceans, recover ecosystems, achieving in the process poverty and zero hunger.

Investigation and Justice in the Face of Scientific Evidence that COVID-19 Was Created in the Laboratory

Hong Kong virologist Li-Meng Yan demonstrated that COVID-19  is of artificial origin, claims it was created in a Chinese laboratory, in addition to other allegations of negligence in containing the virus and investigations of United States and Great Britain that traced its origin to the laboratory in Wuhan China. The NGO Arca Tierra demands an international investigation and the application of justice in the face of this alleged global genocide. We even demand that the Chinese authorities collaborate in the investigation. If they continue to deny this compelling evidence, it would be necessary to question whether the Chinese regime has the full responsibility.

We also urge the international community to adopt measures and policies that monitor virus experimentation. In these investigative, justice, and policy development efforts, the other derivative strains of COVID-19 are also considered, to determine whether the laboratory-created virus evolved as quickly or other strains were created.
