According to new study, the Philippines alone contribute about 1/3 of the global ocean plastics - much higher than those coming from the continents of Africa, N. America, S. America, Europe, and Oceania COMBINED! [Please see thread]
In tackling ocean plastic pollution, we need to know where they are coming from and what are factors playing a role in their transport from settlements to oceans. [2/13]
The newly released study of Meijer et al. (2021), entitled "More than 1000 rivers account for 80% of global riverine plastic emissions into the ocean," highlighted the following points: [3/13]
🔹In 2015 alone, rivers contributed 0.8-2.7 million tons of plastic into the oceans. Of the 100,000 rivers included in the study, only 1/3 actually contributed to it - with the remaining 2/3 emitted almost no plastic to the ocean! [3/13]
🔹The research suggested that smaller rivers played a much larger role than previously thought - with 1,656 rivers contribute 80% of plastic inputs to the ocean. This differs from previous studies showing that only 5 rivers or 162 rivers contributed the 80%. [4/13]
🔹Most of the world’s largest emitting rivers are in Asia, where about 81% of the ocean plastics are emitted. The Philippines, the top-emitting country, alone contributes around 36.4% of the world's total - much higher than some of the continents combined! [5/13]
🔹Seven out of the 10 top-emitting rivers are from the Philippines, with Pasig River alone contributing 6.4% of global river plastics - higher than the contribution of North America (5.4%), Europe (0.6%), and Oceania (0.37%) combined. [6/13]
🔹Some important factors determine how rivers contribute more than the others: (1) they are from areas with poor local waste management practices, (2) they have cities nearby, (3) experience more rainfall, and (4) the cities themselves are near the coast. [7/13]
🔹Though richer countries produce much more plastic waste per person than poorer countries, the probability of having more plastics draining into the ocean is affected by the climate, geographical setting, and local waste management practices. [8/13]
In summary, this study showed the importance of having a global approach in tackling the world's ocean plastic pollution. Focusing mitigation strategies in richer countries won't make much difference because their ocean plastic inputs are low. [9/13]
Instead, they should help poorer countries in improving waste management facilities and practices. We must also speed up our shift to more sustainable alternatives to plastics - because the problems will just continue circulating and worsen if won't make drastic actions. [10/13]

Inaasahan pa rin ang mga pag-uulan sa Luzon, Visayas, at kanlurang bahagi ng Mindanao ngayong gabi dahil sa monsoon trough. Ang maulang panahon ay posibleng magtagal pa hanggang Biyernes. [Thread]
📌Ano ang Monsoon Trough?

Ito ang bahagi ng Intertropical Convergence Zone (ITCZ) na nakadugtong sa monsoon system (hal. habagat) at kadalasang may mga sirkulasyon o namumuong mga bagyo.
Sa kasalukuyang konteksto, and Monsoon Trough ay linya na na kung saan nagsasalubong ang northeasterly trade winds (mula sa hilaga) at southwest monsoon (mula sa timog) na mas madalas ang mga pag-uulan.

#ProtectTheOcean | The Ways to Protect Our Ocean

Former President Bill Clinton once said, “We know that when we protect our oceans, we’re protecting our future."
As part of the celebration of World Oceans Day with the theme “The Ocean: Life and Livelihoods” and as part of Philippine Environment Month, we shall respond to this by doing our duties and responsibilities as humans in keeping our ocean clean and healthy.
Here are some of the ways to protect our ocean:
1. Be mindful of your carbon footprint and limit your energy use.
2. Choose seafood that is both safe and sustainable.
3. Reduce your use of plastic products.
4. Help in the cleaning of the beach.

June is a typical start of the rainy period, especially for the western sections of the country. Here's what to expect in the country this June 2021! ImageImageImageImage
🔺 It's important to note that despite the onset of the rainy season, warm and humid weather conditions will still occur. Though the rains of the southwest monsoon provide relief from the heat, there are "monsoon breaks", that can still cause generally fair and hot weather days.
🔺 With the onset of the rainy season for Type 1 climate areas (western sections of the country) last June 4 and the expected persistence of the southwest monsoon (habagat), the western sections of the country typically receive most of the rains this month.
