1) ...ดอกหญ้า. ที่โรย รา..ไม่สามารถ ปลิว... I think the flowers are of 'dandelions' (edible, nutritious leaves). I would collect the seeds and let them loose in a park nearby ;-) - the next best thing to releasing them in the wilderness. Perhaps this is even better than releasing birds for 'merit'. Caged souls can still be free!

2) ...ขยะ ที่กำลัง ขยาย วงกว้าง เข้า ครอบงำพื้นที่อยู่อาศัย ของปลา... this is true and sad. The fish we eat can also contain high level of micro-fibre plastics (from our cloths and 'degradable' plastics). We are living/dying in our own wastes and we don't even think about it. Can we use more natural fibre clothes? Without encouraging use of pesticides and clearing of forests?

3) For you to write about?
