1One of the main problems is the lack of sewers, 2overcrowding, 3misbehavior when dividing garbage into organic and inorganic, 4 and the lack of habits when it comes to not throwing garbage on the floor.
2 -
the measures they have to have is subdivision of baskets for organic and inorganic material, installation of sewers, fine for those who contaminate public roads

My contribution would be to encourage and try to instill these low-pollution habits in my neighbors or acquaintances, relatives and make them understand the importance of why they are carried out.

Test:
Today we have to understand that in order to develop optimally in our work environment, it is essential that it be healthy, optimal and pleasant for human life. Pollution today is not only physical but can also be noise, climate, energy and even in terms of the attitudes of the people around us.
That is why the work environment should be as decontaminated as possible against anything that affects human viability or good work.
Explanation:
Today, domestic waste is the least controlled waste, and the one that is emitted the most en masse, many people are not aware as daily life requires a rhythm of life that they do not stop to think about the importance of this problem.
In immunology two types of immune response are described depending on whether there is prior contact with the antigen.
• At this first contact, only lymphocytes with receptors specific to the antigen in question are stimulated and lead to the production of antibodies capable of neutralizing it. The lymphocytes capable of recognizing a specific antigen are very few and the production of antibodies - of low intensity and limited duration - is detectable only after a period of latency of several days. This is called the primary response. The specificity of the resulting seropositivity, however, makes it possible to detect contamination (seroconversion).
• Upon re-contact with an antigen that has already triggered a primary response, specific antibody production is found to increase rapidly after a short latency period. The secretion of IgG then reaches levels much higher than those observed during the primary response, while that of IgM is of the same order. This early and intense response, called secondary response, most often results in the destruction of infectious agents before any clinical sign.
• Many centuries before the discovery of microbes, it was noted that people who developed a contagious disease without death were then specifically immunized against the disease, without being protected against others.
• The ability to react appropriately to an already received stimulus supposes the existence of a memory. The immune memory is based on the existence of memory B and T lymphocytes, resulting from the clonal expansion due to the first contact with the antigen. Their lifespan is significantly higher than that of other lymphocytes and their high reactivity gives its rapid and intense character to the secondary response.
