1. PROPER WASTE
MANAGEMENT

2. WASTE MANAGEMENT
 Refers to the process by which garbage is properly collected, transported,
and disposed of.
 In the Philippines, waste management is a major environmental concern,
because of the tons of garbage that are thrown every year into the
dumpsites and it is already filled up.
 Due to increase in population, many materials are used and the materials
are dump as garbage. Also, decreasing of the resources on Earth.
 To address the concern on waste management, five R’s is introduced:
reduce, reuse, recycle, recover, and repair.

3. REDUCE
 Use only the resources that is truly need, use fewer resources, and
throw away fewer things, therefore help to reduce the world’s
waste.

thru emails, because more papers produced, more trees are cut off. We
should reduce the usage of papers.
5. Do not play with water. Close the faucet after use, when there is leaking
faucet, repair them immediately to avoid wastage of water.
