  9. 9. EFFECTS OF WASTE…• Affects our health• Affects our socio-economic conditions• Affects our coastal and marine environment• Affects our climateAccording to NAS:• Some countries are expected to become warmer, although sulfates might limit warming in some areas.• Scientists are unable to determine which parts of those countries will become wetter or drier, but there is likely to be an overall trend toward increased precipitation and evaporation, more intense rainstorms, and drier soils.• Whether rainfall increases or decreases cannot be reliably projected for specific areas.
  10. 10. 3R’S• RECYCLE - processing of used materials or waste into a new product. Ex. Recycling a paper• REUSE – the item is used again in the same function. Ex. Reusing envelops, donating toys tocharity and use rechargeable batteries.• REDUCE – to make something smaller.
  11. 11. Waste Generation by Country(Global Waste Survey Final Report Published by IMO 1995)*
  12. 12. Waste Generation in thePhilippinesIn Metro Manila:• It is estimated that 25 million m3 of acid and alkaline liquid waste is disposed of annually from the electronics industry.• Almost 2,000 m3 of solvents and 22,000 tonnes of heavy metals, infectious wastes, biological sludges, lubricants and intractable wastes are disposed of on land or into water courses.• 4,000 tonnes of solid wastes are generated daily. Of these, only about 3,400 tonnes are collected and transported to existing sites.

  16. 16. Compendium of the Social Doctrineof the ChurchChapter Ten: SAFEGUARDING THE ENVIRONMENT466. Care for the environment represents a challenge for all ofhumanity. It is a matter of a common and universal duty, that ofrespecting a common good,[979] destined for all, by preventinganyone from using "with impunity the different categories of beings,whether living or inanimate - animals, plants, the natural elements -simply as one wishes, according to ones own economic needs".Responsibility for the environment, the common heritage ofmankind, extends not only to present needs but also to those of thefuture. "We have inherited from past generations, and we havebenefited from the work of our contemporaries: for this reason wehave obligations towards all, and we cannot refuse to interestourselves in those who will come after us, to enlarge the humanfamily".[984] This is a responsibility that present generations havetowards those of the future,[985] a responsibility that also concernsindividual States and the international community.
  17. 17. Compendium of the Social Doctrineof the ChurchChapter Ten: SAFEGUARDING THE ENVIRONMENT468. Responsibility for the environment should also find adequateexpression on a juridical level. It is important that the internationalcommunity draw up uniform rules that will allow States to exercisemore effective control over the various activities that have negativeeffects on the environment and to protect ecosystems by preventingthe risk of accidents. "The State should also actively endeavourwithin its own territory to prevent destruction of the atmosphere andbiosphere, by carefully monitoring, among other things, the impact ofnew technological or scientific advances ... [and] ensuring that itscitizens are not exposed to dangerous pollutants or toxicwastes".[986]
