2. Air Pollution
Air pollution occurs when the air contains gases, dust, fumes or odor in harmful amounts. That is, amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials.
The substances that cause air pollution are called pollutants. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Primary pollutant examples include carbon monoxide from car exhausts and sulfur dioxide from the combustion of coal.
Further pollution can arise if primary pollutants in the atmosphere undergo chemical reactions. The resulting compounds are called secondary pollutants. Photochemical smog is an example of this.

3. How Green is UST?
The University is considered as one of the greenest areas within the heart of Metro Manila. The campus showcases a botanical garden which serves as home and cultivation area for a wide range of plants and trees. It also has a field which becomes one of Sampaloc area’s catch basins. The university also features the Benavides Garden which has different types of foliage and landscaping.
ISSUE
University of Santo Tomas is considered as one of the greenest areas in Sampaloc, Manila, but also a source of air pollution because of the vehicles inside the campus. We observed that the number of trees inside the campus is not enough to absorb the daily amount of carbon dioxide emitted by the vehicles.

12. 1
Recommendation
Utilize green spaces found in the university campus, to increase the number of trees in the campus, replant and replace trees that have been damaged or uprooted in previous typhoons.

13. 2
Recommendation
In the choice of vegetation and trees, we recommend trees that are endemic to the Philippine context and hence are fully equipped and strong against calamities present in the UST Campus setting, along with trees that purify the air, we recommend species of plants to complement the trees, these plants help offset the polluted air through natural components present in these plants.

14. Recommended: Indigenous Tree Species2
Recommended: Indigenous Tree Species
Indigenous tree species have evolved in the same area, region, or biotype where the forest stand is growing. These trees have adapted to the specific ecological conditions of the area.
Left to Right: Examples of indigenous trees and foliage, Malak-Malak, Ipil, Balayong, Cerbera

15. 3
Recommendation
As parts of the campus are slowly being swallowed up by buildings, we recommend the conversion of rooftops, hallways [found in midcentury and international style campus buildings] into green spaces, through plantboxes and rooftop gardens to house air purifying plants, an example of this can be found in the roof of the Main Building

16. 4
Recommendation
Streetscaping is another overlooked factor in the layout and design of the campus, lessen the hard and covered parts of sidewalk, and allow the intrusion of lawns and green areas in sidewalks, while this allows in more spaces to plant trees and softscape such as shrubs, plants, and small trees, it would also allow in more permeable space which could sip in water during rainy days

17. 5
Recommendation
Develop a Car pooling Service for students living 5-10 km away from UST to decrease the volume of cars being drawn to the area.
