What are the 4 laws of ecology?


The basic principles of the sustainability of living beings indicate the properties necessary for an ecosystem to maintain itself indefinitely. There are 4 of them, they are fulfilled by natural ecosystems and are not fulfilled by most of the artificial ecosystems where man lives or where man has intervened too much.

1. Ecosystems do not waste resources: they REDUCE consumption and RECYCLE all their elements so that they get rid of waste and replenish nutrients, forming part of a coherent cycle. Many times man establishes the flow (of nutrients, materials…) only in one direction causing problems of depletion in some places and pollution in others.

For example, the residues of organic products (organic waste), instead of returning them to the soil (compost) are massively deposited in landfills or thrown into the waters (rivers and seas) where they pollute a lot (eutrophication). On the other hand, as arable land is highly exploited, fertilizers are required and as the previous ones are thrown away, chemical fertilizers are used which, when used in excess, contaminate groundwater and affect the food chain. To this must be added the contamination at the place of extraction, transportation… We must remember that with organic waste and with the waste from sewage treatment plants we can make the best fertilizer (composting), recycling nutrients, as Nature does.

As we approach the celebration of Earth Day, we took it upon ourselves to learn more about one of the first environmentalists in history who has been a big part of the progress toward a more sustainable world. Barry Commoner is the founder of modern ecology and one of the most provocative thinkers and mobilizers to make environmentalism a political and social cause. Through his work he encouraged recycling, organic food and the reduction of fossil fuel use, constantly questioning over-production and consumerism. As a high-level academic and activist, he understood that living in balance with the Earth could be summed up in 4 principles of ecology that we can all apply in our daily lives.

We think of these actions as individual events but they are all interconnected. Ultimately, pollution to the atmosphere creates a high temperature rise in the ocean, causing an imbalance in marine ecosystems, rising sea levels and an increase in natural disasters. Plastic that we think is not our problem ends up in the sea being unconsciously ingested by the fish we catch and eat.

And this law, the environmental assessment law, is the framework that establishes the exclusive competence of the State in matters of basic legislation on environmental protection. Contrary to what may appear at first sight, it not only facilitates the incorporation of sustainability criteria in the evaluation of projects, but also in strategic decision-making, through the evaluation of plans and programs.

But what are laws that protect the environment? In general, they are all those legal provisions with the rank of law (laws, legislative decrees, emergency decrees, treaties, congressional regulations, regional, provincial and state regulations and municipal ordinances) that ensure the respect and care of our environment, whether terrestrial, aquatic or atmospheric, and of the beings that live in them, flora and fauna.

Every person shall have the right to have the Secretariat, the States, the Federal District and the Municipalities make available to them the environmental information they request, under the terms provided by this Law. Environmental information is considered to be any written, visual or database information available to the environmental authorities on water, air, soil, flora, fauna and natural resources in general, as well as on the activities or measures that affect or may affect them. Any request for environmental information must be submitted in writing, clearly specifying the information requested and the reasons for the request.
