Limang pangungusap na nagpapahayag ng opinyon tungkol sa suliraning pangkapaligiran​
yaroslaw [1]

Answer:

1. Nararapat lamang na itapon natin ang basura sa tama nitong kalalagyan upang di maduming tingnan ang ating kapaligiran at upang malayo tayo sa mga sakit kapag itoy nagkalat dahil sa ulan.

2. Sa aking palagay nararapat na ding itigil ang pagputol ng mga puno upang di makalbo ang kagubatan na siyang tahanan ng mga hayop at upang walang gaanong pinsala o baha pag dumating ang bagyo.

3. Karapat-dapat na ding itigil ang planta dahil ang usok nito ay nakadagdag ng polusyon sa hangin at higit pa nakakasira sa ating ozone layer.

4. Nararapat na ding hinay-hinayin ang pagdami ng tao dahil isa din itong suliranin sa ating pangkapaligiran ang pagdami ng populasyon ng tao.

5. Bilang tao nararapat tayong maging responsable sa hakbang na ating gagawin pag-isipan nating maigi kung ito ba'y nakakatulong o nakakasama sa kapaligiran na siyang dahilan ng pagkaubos ng ating likas na yaman.
