Sepatutnya negara kita patut menggalakan penanaman pokok pokok hijau disekitar rumah dan kawasan awam. Pemaju perumahan dan bandar sepatutnya menggalakkan penghijauan alam sekitar dengan menanam pokok pokok dan mereka kawasan hutan hijau diaantara kawasan yang dimajukan.
Dengan adanya penghijauan alam sekitar dengan pokok pokok dapat menyeimbangkan penyerapan air dan suhu dipermukaan bumi serta menapis habuk habuk diudara. Selain dari itu ianya dapat menghasilkan oksigen.
Diarticle dibawah kajian didapati bahawa hutan konkrit sebenarnya menyerap dan menyimpan haba. Bangunan yang tinggi menghalang laluan angin, lalu debu terampai yang tercemar tidak dapat dialih dan dikitar dengan angin..
Disebabkan ini lah udara menjadi kurang sihat dan tidak berkualiti..
banyak lagi perlu di ambil kira ....tapi jika ingin rumah rasa sejuk dan tidak panas, tanamlah pokok pokok yang dapat tumbuh rendang. Tapi ingat tanam pokok jarak yang agak jauh dari kawasan rumah jika pokok yg hendak ditanam boleh membesar seperti kayu balak dsbnya..
jika rumah berteres dan berkonkrit, mahu buatlah bekas planters yang besar dan setinggi lutut , dan berlantai, supaya akar tidak merayap jauh kebawah tanah.
Tanamlah pokok supaya ianya boleh hidup rendang dan meneduhkan keadaan sekeliling dan oksigen dihasilkan dari daun pokok ini dapat menyegarkan walaupun diwaktu panas terik.
Jika kita lihat dikawasan rumah kampung, walaupun kawasan bertanah, tapi bila hari panas terik dan awal pagi cuaca amatlah menyegarkan.
Jika rumah semua tanah dikonkrit simen dan batukan, memang lah panas apatah lagi tiada pokok meneduhkan dan akar menyimpan dan menyerap air...
akhir kata tanamlah pokok, kalau tak ditanah, tanam lah didalam raised box planters yang tmbul diatas tanah, maka senang mengawal pertumbuhan akar pokok...
bacalah article dibawah utk kita fikirkan bersama...
THE ever-growing concrete jungle is threatening to choke us, experts say.
City Pollution is soaring in summer because vast swathes of paving and brick retain too much heat at night, and tall Buildings block the cooling winds that should clear airborne pollutants, researchers add.
Town Planners across the World must change tactics to improve air quality, according to the report by the National Centre for Atmospheric Research.
Greener Cities with more Lakes and Ponds would have less pollution, even if carbon dioxide emissions from cars and homes stayed the same, said the US group.
"The night-time temperature would be lower and winds would become stronger, blowing the pollution out to sea,' it added.
The international study was held to examine reports of falling air quality in fast-growing cities, particularly those near coasts.
The key reason was found to be man-made — but not the usual suspects of global warming and increasing CO2 emissions. Instead, the paving over of green spaces and bigger building projects was blamed.
In Houston, Texas, for example, 'the developed area has a major impact on local air pollution', said the group.
'If the city continues to expand, it is going to make the winds even weaker in the summertime and that will make air pollution much worse,' the report's authors added.
Houston's authorities have tried to tackle air pollution with strict carbon dioxide emission targets.
Other cities have taken similar steps, including London with its congestion zone and bike hire scheme. However, the capital is also building its tallest skyscraper, the Shard.
The report will be published in the Journal of Geophysical Research later this month.
