Environmental-Awareness-Biodiversity-and-it's-Threats
- 2. ENVIRONMENTAL AWARENESS It is the process of being aware of our natural environment and for an individual to make choices that can benefit the environment rather than to cause harm on it.
- 3. WHAT IS THE IMPORTANCE OF KNOWING/STUDYING ENVIRONMENTAL AWARENESS? The need to know and study environmental awareness is very important because most of the environmental issues are the outcomes of an individuals’ way of living such as improper waste management that leads to pollution, population explosion that can lead to industrialization and urbanization.
- 4. Our climate, our lives and the future of the human civilization are all at risk if we do don’t do something with all these issues. If we make simple steps and adjustments in our daily routine we can still restore, help and maintain our environment. We can still save and prepare the future of our next generation. How to Solve Environmental Problems?

Major Environmental Laws Republic Act 6969 (Toxic Substances, Hazardous and Nuclear Waste Control Act of 1990) This law aims to regulate or prohibit the importation, manufacture, processing, sale, distribution, use and disposal of chemical substances and mixtures the present unreasonable risk to human health. It likewise prohibits the entry, even in transit, of hazardous and nuclear wastes and their disposal into the Philippine territorial limits for whatever purpose; and to provide advancement and facilitate research and studies on toxic chemicals.
- 16. Major Environmental Laws Presidential Decree 1586 (Environmental impact Statements (EIS) Statement of 1978 This is a planning and management tool that helps the government, decision makers, the proponents and the affected community addresses the negative consequences or risks on the environment.
- 17. Biodiversity
- 18. Biodiversity It is the biological diversity in an environment as indicated by numbers of different species of plants and animals. It is the variety of life on Earth at all its levels, from genes to ecosystem Bio = Life Diversity = Variety It is affected by many Earth system processes and phenomena, including:
- 19. Climate Condition The amount of sunlight absorbed at different latitudes, temperature. 4 Species Interaction Species depend on other organisms for food, shelter, or compete for food, space, or nesting sites. 3 Extinction Decreases biodiversity. 2 Evolutionary Process Generetes new species traits. 1
- 21. Changes in Biodiversity Loss of Species Human activities have led to a significant loss of species diversity worldwide, with many plants, animals, and microorganisms facing extinction. The loss of key species can have cascading effects on ecosystem dynamics and functioning.
- 22. Changes in Biodiversity Species Interactions Changes in biodiversity can alter species interactions within ecosystems, affecting processes such as predation, competition, and mutualism. Disruptions to these interactions can lead to imbalances and ecosystem instability.
- 23. Changes in Biodiversity Ecosystem Resilience Reduced biodiversity can decrease the resilience of ecosystems to environmental disturbances, making them more vulnerable to factors such as climate change, disease outbreaks, and habitat destruction.
- 25. Threats to Biodiversity Habitat Loss/Destruction ▪ A process by which a natural habitat becomes incapable of supporting its native species. ▪ Habitat Loss/Destruction can be the result of land conversion, lumber harvesting, material minings, and agriculture.
- 26. Threats to Biodiversity Habitat Fragmentation ▪ A process by which a large expanse of habitat is transformed into a number of smaller patches of lesser total area. ▪ Habitat fragmentation is the result of the creation of pastures or crop fields, as well as hydro-electric reserviors.
- 27. Threats to Biodiversity Habitat Degradation ▪ It is when an area can no longer support native wildlife. ▪ Pollution, invasive species and disruption of ecosystem processes such as the changing intensity of fires are some of the ways that can cause habitat degradation.
- 28. Threats to Biodiversity Invasive Species ▪ These are organisms that are not indigenous or native to an area. While not all non-native species are invasive, the ones that are classified as such can cause great economic and environmental harm to an area.
- 29. Threats to Biodiversity Climate Change ▪ Can disrupt the ecological balance between interdependant and often endangered plant and animal species. ▪ It is the significant and long lasting change in the Earth's climate and weather patterns.
- 30. Threats to Biodiversity Pollution ▪It is the action of making an environment unsuitable or unsafe for use by introducing man-made wastes.
- 31. Threats to Biodiversity Overexploitation ▪It is when a living resource is removed from the environment at a rate faster than it can be replaced. ▪ It can also be known as overfishing or overharvesting, depending on which species is being harmed.
- 32. Threats to Biodiversity Overpopulation ▪It refers to the condition of having a population so dense as to cause environmental deterioration, an impaired quality of life, or a population crash.
- 33. Biodiversity Loss ▪Biodiversity loss refers to the decline or disappearance of biological diversity. ▪Biodiversity has declined at an alarming rate in recent years, largely as a result of human activities.
- 34. Main Causes of Biodiversity Loss Climate Change ▪It impacts biodiversity in various levels: species distribution, population dynamics, community structures and the functioning of the ecosystem.
- 35. Main Causes of Biodiversity Loss Pollution ▪Pollution causes changes in energy, different radiation levels, and unwanted biological, physical and chemical changes in the biosphere, which includes all other living creatures.
- 36. Main Causes of Biodiversity Loss Destruction of Habitat ▪The loss of habitat can fragment ecosystems and can cause species extinction. ▪It negatively influences biodiversity directly through its impact on species ubandance, genetic diversity, species richness and species distribution.
- 37. Main Causes of Biodiversity Loss Overexploitation of the Natural Environment ▪The overexploitation of natural resources refers to their consumption at a speed greater than that of their natural regeneration, which has an obvious impact on the planet's flora and fauna.
- 38. Main Causes of Biodiversity Loss Invasive Alien Species ▪Invasive species are organisms that entered and established in the environment from outside of their natural habitat. ▪They act as predetors, competes for food, hybridise with native species, introduce parasites and diseases, etc.
- 39. Consequences of Biodiversity Loss
- 40. Consequences of Biodiversity Loss Extinction of Species ▪ The alteration and destruction of habitats puts thousands of species in danger of extinction.
- 41. Consequences of Biodiversity Loss Threats to Human Beings ▪ Biodiversity loss endangers human well-being by affecting soil and water, which are fundamental to food production.
- 42. Consequences of Biodiversity Loss Proliferation of Pests ▪ Imbalance in ecosystems can lead to the emergence of pests that damages crops.
- 43. Consequences of Biodiversity Loss Increase in CO2 Imission ▪ The capacity of forests and oceans to absorb CO2 decreases if their ecosystems are adversely affected.
- 44. Ways to Prevent Biodiversity Loss
- 45. Ways to Prevent Biodiversity Loss Be Environmentally Aware ▪In order for us to prevent the loss of biodiversity, we should first be aware of the problems that surrounds us and the changes that was made.
- 46. Ways to Prevent Biodiversity Loss Conservation ▪ This refers to the protection, preservation, management, and restoration of wildlife and natural resources like forests and bodies of water.
- 47. Ways to Prevent Biodiversity Loss Conservation In-Situ Conservation Ex-Situ Conservation ▪ Refers to the conservation of habitats, species and ecosystems in nature or where they naturally occur. ▪ Refers to the conservation of biodiversity outside of natural habitats.
- 48. Ways to Prevent Biodiversity Loss Restoration Ecology ▪ Renewing/ reatoring degraded/ damaged/ destroyed ecosystems and habitats due to human activities.
