Environmental Conservation Honor
Nature Study
Requirements
- Explain the difference between ecology and environmental conservation.
Answer: Ecology is the science that studies the relationships between living beings and the environment (interactions, populations, ecosystems). Environmental conservation is the practical application of this knowledge to protect natural resources, species, and habitats. Ecology generates theoretical knowledge; conservation uses that knowledge to preserve, recover, and manage nature. — Ecology was coined by Ernst Haeckel in 1866 ("oikos" + "logos" = study of the home); environmental conservation gained momentum with Aldo Leopold in "A Sand County Almanac" (1949) — the basis of the modern environmentalist movement; IBAMA applies conservation in Brazil while INPE and universities do theoretical ecology of the Atlantic Forest currently.
- Write an essay of at least 500 words on the theme: The increase in the human population and how this is a threat to its own existence on Earth.
Answer: Your essay should discuss population growth (about 8 billion today, projected to reach 10 billion by 2050), pressure on resources (water, food, energy), loss of biodiversity, climate change, disorderly urbanization, and inequality. Include causes (hunger, wars, migration), current effects, and proposals (education, family planning, sustainability) with a minimum of 500 structured words. — The Limits to Growth report (Club of Rome, 1972) already warned about planetary limits; the UN projects a population peak of 10.4 billion in 2086; today's resource consumption requires 1.7 planets per year according to the Global Footprint Network — the theme is central to the UN's 2030 Agenda for Sustainable Development currently in force.
- What does the term "death" of a lake or river mean? Is there any lake or river in your region or city that is classified as "dead"?
Answer: The "death" of a body of water means the total loss of aquatic life (fish, plants, microorganisms), caused by eutrophication, chemical pollution, sewage, deforestation, or alteration of the course. In Brazil, the Tietê River in São Paulo has had historically "dead" stretches since the 1970s; the Doce River suffered a partial "death" in Mariana in 2015. — Eutrophication is the increase of nutrients (nitrogen/phosphorus) that causes an explosion of algae, a lack of oxygen (anoxia), and the death of aquatic fauna; the Samarco disaster in Mariana 2015 released 60 million m³ of tailings into the Doce River; the Tietê River is studied as the case of the most severe urban eutrophication in modern Brazil currently.
- Conduct a study of a small stream that passes within or near your city. Present a report of at least 300 words on your observation of the following items:
- Signs of purity
- Signs of deterioration and death
Answer: Signs of purity: transparent water, no strong smell, the presence of small fish and larvae, preserved riparian forest, a clean stone or sand bottom. Signs of deterioration: dark or greenish color, foam, bad smell (sewage), silting, garbage, absence of fauna, destroyed riparian forest, and excess algae (eutrophication) on the surface. — Bioindicators are the standard of CETESB and of CONAMA Resolution 357/2005; macroinvertebrates such as Plecoptera only live in clean water, while Chironomidae larvae appear in polluted water; riparian forest is required by the Forest Code (Law 12.651/2012) with a minimum of 30m on small urban Brazilian rivers currently in force today.
- After investigating the previous requirement, do one of the items below:
- If the stream shows signs of purity:
- If the stream shows some of the signs of deterioration mentioned above, do at least 2 of the items below:
Answer: For a clean stream: set up a monthly monitoring plan, publicize it in the community, plant native seedlings in the riparian forest, and mark it with educational signs. For a deteriorated stream: organize a group cleanup of the streambed, plant riparian trees, report irregular sewage to IBAMA, and organize environmental awareness lectures in the local neighborhood. — Group cleanups are provided for by Law 12.305/2010 of the National Solid Waste Policy; reporting to IBAMA can be done through the Green Line 0800-61-8080; reforestation of riparian forest requires native regional species — a principle of the 2012 Brazilian Forest Code currently in force today.
- Make a visit to the garbage dump of your city or neighborhood and see how the garbage is treated. Find out:
- How many tons of garbage are dumped daily
- What attempts are made to recycle part of this garbage?
- Is part of the garbage burned, or is it all buried?
- What is the cost, per person, per year, to handle the garbage in your city
- What happens to cars that are no longer of any use in your region
Answer: You visit the municipal landfill/dump and note: tons/day (a medium-sized city generates 0.5-1 kg per inhabitant per day), percentage recycled (Brazil ~3%), whether there is incineration or just landfilling, annual per capita cost (average R$ 100-300), and the destination of scrapped vehicles (regular dismantling, scrapyard, or the Detran's e-ATPV). — The National Solid Waste Policy (Law 12.305/2010) requires reverse logistics and sanitary landfills instead of open dumps; Brazil still has about 2,500 irregular open dumps; the e-ATPV (Electronic Authorization for the Transfer of Vehicle Ownership) regularizes dismantling since 2020 according to Contran Resolution 466/2013 currently in force.
- Do one of the items below:
- Visit the nearest plant or sanitary landfill. On this visit, carry out the items below or hold the Recycling and Recycling – Advanced honors:
- Visit a water purification plant:
Answer: Sanitary landfill: note the soil waterproofing (HDPE liner), leachate collection, biogas burning, daily compaction, and covering with earth. Water treatment plant: record the stages — capture, coagulation, flocculation, sedimentation, filtration, chlorination, and fluoridation up to distribution. Document with photos and a report describing each stage observed. — Sanitary landfills follow NBR 8419/1992 with a waterproofing HDPE liner; biogas (methane) can generate electricity; treatment plants follow the standard of Sabesp/Cedae in SP/RJ — chlorination since 1908 eliminates cholera (Law 11.445/2007 on basic sanitation) and kills about 99.99% of the pathogens in treated potable water.
- Read and write a summary of a book about environmental issues.
Answer: You choose a book about the environment (e.g.: "Silent Spring" by Rachel Carson, "Before Nature Dies" by Jean Dorst, "The World Is Flat" by Thomas Friedman) and write a summary of 1-2 pages with the central theme, the author's main arguments, relevant data, your personal opinion, and lessons for the Pathfinder. — "Silent Spring" (1962) denounced DDT and started modern environmentalism; it was the spark for the creation of the EPA in the USA and the Stockholm Conference in 1972; summarizing trains critical thinking — a central skill of environmental education according to UNESCO in the International Environmental Education Program currently in force today.
- Have the Endangered Animals honor.
Answer: You first need to complete the Endangered Animals Honor (code EN-058) — a mandatory prerequisite that teaches about threatened fauna, the IUCN Red List, ICMBio, Law 9.605/98, and conservation actions. Present the badge of that honor to the instructor before starting the Environmental Conservation Honor. — EN-058 is in the Nature Study area and provides the foundation on fauna at risk; the prerequisite system of the SAD Manual ensures pedagogical progression — whoever masters the identification of threatened species can apply that knowledge in practical environmental conservation projects, integrating zoological theory and management practice in the Brazilian field currently.
