Brazilian environmental problems, especially the destruction of our forest reserves, have long been a matter of great concern.

If we know the structure and operation of an environment, we can take various measures to protect or recover areas.

Currently, governments and members of civil society in various countries are organizing themselves in the form of entities and associations in order to define procedures that encourage the preservation of nature and disseminate environmental issues.

The work of these organizations requires the collaboration of experts from various fields, including the natural, political and social sciences.

Its objectives may be varied, such as conducting research, promoting studies and enforcement of environmental protection laws, designing and implementing education projects in this sector, or addressing a more specific field, such as fighting for the preservation of an endangered species. of extinction.

In addition, it is crucial that every segment of society, and in particular every citizen, have knowledge of environmental problems and participate in their solutions. Interest in these issues is growing daily in all parts of the world. Several representatives of society are realizing that a concerted effort is needed to preserve the environment on Earth and to ensure the improvement of the population's quality of life.

The main problems

Firstly, it is important to remember that recycling materials in the environment is a lengthy process. When the removal of a particular element from the soil is faster than its replacement, there is a depletion, which manifests itself through a drop in productivity. Farmers know that plants need varied nutrients, which are found in the soil thanks to the activity of certain microorganisms.

If successive crops are grown, these nutrients eventually run out and production begins to fall. There will then be two alternatives: artificially adding the nutrients removed, or allowing the recomposition to take place normally, waiting a while for the soil to recover.

Nonrenewable natural resources, once depleted, are not being reused, and therefore their use must be made with great care. Knowing that one day they will be missing, man needs to think in advance of a way to replace them with others capable of performing similar functions.

As renewable resources require a certain amount of time to replenish, humanity will have no stocks if consumption is not controlled and the human population grows beyond a certain limit. Rational use of natural resources means increasing the productive capacity of the environment in favor of man, without, however, degrading nature.
