3. It is understood by anthropic intervention, to all the processes
where the human is included. He intervenes in nature in a disastrous
way since we instead of adapting to nature what we do is that it suits
us, causing with it natural catastrophes. Human impact on the
environment or anthropogenic impact on the environment includes
impacts on biophysical environments, biodiversity, and other
resources.

4. Water pollution
Biological agents of pollution may be present in feces as microorganisms that can
cause serious and even fatal diseases. Detergents are chemicals that alter the physical
properties of water. Food residues and fats that lead to water are attacked by
decomposing organisms.

5. Deterioration of air
The contamination that accumulates in the air can be of two types:
- Primary contamination: Produced by substances that are
released into the atmosphere and do not undergo changes or
reactions to become new substances.
- Secondary contamination: It originates when the compounds of
primary pollution, once they reach the atmosphere, react to form
new components that are also highly polluting.

6. Consequences:
- Reduction of the ozone layer: The ozone layer is a belt of natural ozone gas
that lies between 15 and 30 kilometres above the Earth as if it were a shield
against the harmful ultraviolet B radiation emitted by the sun. Reducing the
ozone layer increases the level of ultraviolet radiation that reaches the
surface of the earth, which in turn can increase the likelihood of excessive
exposure to ultraviolet rays and associated health problems, such as
Cancer, cataracts, and immune system inhibition.
- Acid rain: Acid rain is formed when moisture in the air is combined with
nitrogen oxides, sulphur dioxide and trioxide emitted by factories, power
plants, heating boilers and vehicles burning coal or oil products containing
sulphur.
- Greenhouse effect and global warming: Air pollution is related to the
greenhouse effect, a phenomenon from which the light from the Sun
penetrates the atmosphere and heats the surface of the Earth.

10. Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of
countless species that create a dynamic and complex ecosystem and is
among the most precious resources to humans. Increased demand for
agriculture commodities generates incentives to convert forests and
grasslands to farm fields and pastures.
The effects of soil erosion go beyond the loss of fertile land. It has led to
increased pollution and sedimentation in streams and rivers, clogging these
waterways and causing declines in fish and other species. And degraded
lands are also often less able to hold onto water, which can worsen flooding.
Sustainable land use can help to reduce the impacts of agriculture and
livestock, preventing soil degradation and erosion and the loss of valuable
land to desertification.

12. • Our well-being depends on the use of natural resources. We extract
resources and transform them into food, buildings, furniture, electronics,
clothes, etc.Other activities resulting from the enormous growth of the
human population with overexploitation of resources, urbanization and
agricultural and livestock activity have undoubtedly contributed to the
deterioration of the environment .
• Quality of life has taken into account the degree of access to the use of
goods and services, regardless of what would happen if the resources
are exhausted, or if the land can assimilate so many changes in the
future or if this model of development can be extended indefinitely, in an
Economic vision and Anthropocentric world.

17. Anthropic impact: search for energy resources
AGRICULTURE
1.- Plant-based foods such as wheat and fruits
2.- Cultivated pastures and fodders
3.- Used fibers
The man, on the contrary, tries to get the maximum yield from
the ecosystem, which is why he tries to maintain the
ecosystems at a youthful stage so he can get the highest net
productivity. Diversity is also reduced by eliminating animal
rivals (rodents, wolves, birds, etc) through the sport of hunting,
or with the use of poisons, etc.

20. • The green economy is defined as that which improves human welfare and
social equity, while significantly reducing environmental risks. In a green
economy, income and employment growth are driven by public and
private investments that reduce carbon emissions and pollution, improve
efficiency energy and resources, and prevent the loss of biodiversity and
ecosystem services.
• The concept of circular economy focuses on the resource cycle and
proposes a model based on reuse, repair, remanufacturing and recycle
existing materials and products, versus the use of raw materials.
