in order to Mariana Castro Azpíroz
April 22 is Earth Day. It all started with an environmental demonstration in 1970, but even though we have commemorated 51 years, we are still immersed in the most serious ecological crisis we face.
In the 1970s, it was legal for factories to discharge any amount of pollutants into soil, air, and water. Because there are no regulations to prevent or restrict it. U.S. Senator Gaylord Nelson declared April 22 “Earth Day” and held a rally in which 20 million people from different cities in the United States participated. In this way, it is possible to put environmental issues on the political agenda And established the country’s “Clean Water and Air Act” and the Environmental Protection Agency (EPA).
First call, first
In fact, the first call to attract attention to environmental issues began in the 1940s. Rachel Carson is a marine biologist, author and pioneering ecologist. He is concerned about the impact of humans on the natural world. . He began to write articles on marine ecology, which gave him a public voice in the international community to raise people’s awareness. In 1964, he published a book about starting the environmental movement: Silent spring, He talked about the abuse of pesticides and its impact on all living things. Carson advocates an environmental ethics, that nature is composed of interconnected and interdependent systems, and questioned the idea that humans should conquer and dominate nature.
Second call, second call
In 1974, Mario Molina and Sherwood Rowland showed that CFC gases in aerosols and refrigerants destroy the ozone layer. They warned of climate change and future environmental impacts. In 1995, their work was awarded the Nobel Prize in Chemistry. The ozone layer protects our planet from ultraviolet rays, which can cause cancer, cataracts and suppress the immune system.. In addition, they also harm plants and plankton, and they are the foundation of the food chain. If these creatures are affected, their impact will reach all levels.
In 1987, the Montreal Protocol was signed, Prohibition of the use of ozone-depleting aerosolsBut despite this, the 2006 record broke the biggest loophole in history. By 2012, 97 hazardous substances were almost completely stopped, and in 2019, the hole was the smallest size since its discovery.In 2020, it measures 24.8 million kilometers2 pcs: About three times the area of the United States.This is 2.6 million kilometers2 pcs It is smaller than maintaining the level of chlorine and bromine in 2000. This is progress, But we still have a long way to go.

Third pass, third pass: let’s start
In September 2000, the “Millennium Development Goals” were formulated. Leaders of 189 countries pledged to achieve 8 goals by 2015, of which 6 focus on human well-being and one is to “ensure environmental sustainability.”. The eighth technically includes: “Establishing a global partnership for development” (but it all depends on what is understood as “development” in the political agenda). Established indicators to monitor progress, but did not achieve the Millennium Development Goals, and postponed them to become the famous “2030 Agenda” in 2015. Of the 51 targets that Mexico has committed to, 37 have reached.
The transition from the Millennium Development Goals to the Sustainable Development Goals means maintaining the same route as the original eight goals, but adding new goals and specifying the key points of the previous goals, so there are 17 sustainable development goals. Transform the 6 people-centered Millennium Development Goals into 5 sustainable development goals, The only MDG for the environment is subdivided into 5 SDGs. Five more are related to prosperity, one is related to peace, and the eighth (now 17) is related to the Global Alliance.
POV: You are part of the ecosystem
As human beings, the way we conceive of our relationship with other creatures implies a wrong dominant position, which separates us from the natural world. We need to understand that we are part of the Earth’s internal system and that we benefit from environmentally friendly products and services. It is neither correct nor feasible to simply dismiss them for nothing.
The Amazonian culture and the Mayan culture have implemented sustainable agroforestry practices from their origins to the present. The Lakota Indians regarded all living things as relatives and humans connected with all the elements of the natural world. Most indigenous groups have a strong relationship with their homes and all the creatures that share space with them. They respect and respect nature, and have the value of maintaining and balancing with nature. Unfortunately, many indigenous groups are considered primitive and uncivilized, destroying their worldview.
We have the information and tools necessary to establish a healthy relationship with the environment: from ancient practices to the latest scientific advances. What matters is how we treat them. We cannot remain passive. The situation of the ozone layer shows us that modifications can be made that benefit all living things and the planet. At a meeting he held in 2019, Mario Molina put forward some feasible suggestions for tackling climate change: efficient transportation systems and buildings, more optimized ecological forestry practices, and replacing natural gas with coal. As well as capturing and storing wind energy and biofuels. We have the solutions and technologies available to make the changes we need. We have 51 years of action; we cannot wait forever.
Mariana Castro Azpíroz Researched molecular biology at UAM Cuajimalpa. He has conducted research in cooperation with the Kumanco Biological and Aquaculture Research Center (CIBAC, UAM-X); in addition, it is also committed to the care and protection of local aquaculture species. Since 2019, he has been committed to science communication and currently conducts environmental education through social networks.
