We join celebrations for Earth Day, World Environment Day, others that remind us to continue to take best care and protect our planet, our partner for life and survival. But how much do we really know of our own world, that part of the Earth that we call our own, especially where we reside/study/work?
Coastal clean-ups are regular events for Earth/Environment celebrations. Millions of people live, are dependent on coastal/marine/fishery resources. But how much do these coastal residents and those who join coastal clean-up know of their wide/marine world (beyond the collected/uncollected garbage)?
How many of our adults/children, including us, can identify various types of shells/fish/ and other marine resources? How many of us know their life cycles, their benefits for people, how people can best protect/sustain these marine resources across generations?
Do we even have any simple coastal barangay-level sea museum/display area so our youth/fisherfolks/all those who live by and depend on the sea/its resources can maximize their knowledge/partnership for common sustainable survival through the years?
We can best protect those that we know about.
Knowledge is power – Our Power/Our Planet – our 2026 Earth Day theme.
Tree-planting/tree-growing are also favorite events for Earth/World Environment Days.
Again, we ask this serious question: how much does an ordinary Filipino student/adult know about trees, plants, and our forests?
For 2026 Earth Day celebration last April 22, with our UP Communications students in our Basic Japanese class, we took time to do a short Earth Walk from the UP Cebu Undergraduate building to the Main Admin Building and back. This was an activity that I used to do with our UP Cebu students when I taught STS (Science, Technology, Society) from the early 1990s.
The Earth Walk goal: to share with the students about the abundance of plants/trees in the UP Campus and their benefits such as food, medicine, housing, others, for people and other living creatures.
Professor Geofe Cadiz researched and catalogued about 208 flowering plants throughout the UP Cebu Main Campus.
This April’s Earth Walk was more precious/significant knowing that a number of our own UP students go without food on certain days. If they are more observant and knowledgeable, there are plants and trees that can provide them with their food right within the UP Cebu Main Campus.
The short Earth Walk was a revelation.
Some students born and raised in urban areas were pleasantly surprised to see, for the first time, the kaimito tree and the tamarind/sampalok/sambag with so much vitamin/mineral-rich fruit ready for harvest!
Now is the season for tambis (or the closely related makopa fruit or in English, the ‘Watery Apple Fruit’, ‘Java Fruit’ or ‘Java Rose Apple’).
So much health benefits from these fruits if effectively, safely harvested for the UP Cebu community to enjoy!
Other fruits to enjoy include santol, mabolo, nangka, banana, papaya, coconut, among others. For sugar source, students can look for the santan flowers as candy substitutes!
It was the first time, too, for many students to see, touch, and smell ilang-ilang which in Tagalog means ‘flower of flowers.’ Also referred to as the perfume tree, ilang-ilang’s scent is much sought after worldwide.
Various references noted that the essential oil obtained from ilang-ilang flowers are ‘anti-pruritic, anti-fungal, antiseptic, and sedative, relieving tension, lowering blood pressure, and reducing fever, and in traditional medicine, this tree is used against fever/blood pressure/ malaria/asthma/various skin conditions/conjunctivitis/hypertension/stomach pains/indigestion/ colic/toothache/others, and, wood used locally for general construction/turnery/making canoes/ boxes/tea chests/plywood.’
If only Earth Walk can be conducted throughout our country, among our students as early as elementary, if only all our trees/plants were publicly marked with their common names/benefits for all to know, can you imagine how knowledge, protected/sustainable accessibility/supply of our rich biodiversity can be beneficial for all, people and planet!
