The role of humans in their environment is clear. They are not merely biological specie but also a social specie which, by their ingenuity and skill, shape and reshape their ecosystem at will. The kind of ecosystem they have, therefore, reflects the values, attitudes, skills, and knowledge or ignorance behind the decisions they make. Today people are becoming more and more aware of pollution and its harmful effects. Little by little, they are being driven to take the necessary precautions in preventing and curbing the various types of pollution.

Laws or measures are being passed to ensure proper sewage and industrial waste disposal. With cooperation among members of the community, a supply clean of water is ensured. Many health hazards have been controlled, while solutions to other remain to be discovered, researched on, and taken care of through science and technology.

Whether our forests, agricultural lands, and water supply will continue to meet our increasing demands, and whether our wildlife will flourish for more years, will depend on what we learn from ecology, and on our efforts to conserve them as natural resources. With regards to the use of forests, many laws or decrees have been passed for their protection. The law may contain information that the logs must be processed locally instead of exported. There are also fire prevention practices and reforestation that have been recommended to the people for better protection of trees in the forests.

Like forests, wildlife too, must be protected. Our idea of protection here is what we call as conservation. This is the use of natural resources so as to derive the utmost benefit for the maximum number of people and for the maximum length of time. Laws have been passed to prohibit the destruction and collection of wildlife species. It can also limit the catch, declaring hunting seasons. Finally, it will set aside areas as national parks and wildlife offices.
