Viewpoint from above with the downstream of Selangor River at Kuala Selangor between manmade and nature in between.
Climate shifts such as sea-level rise, altered rainfall, and human activities such as urbanization, aquaculture, timber, fish, crustaceans, and shellfish mining, and over-exploitation are significant threats to the ecosystem of mangroves.
Toxic man-made chemicals carried by river systems can destroy animals living in mangrove forests from upstream sources, while oil emissions can smother the roots of mangroves and suffocate the trees.
This image shows the end of the river Selangor irrigation journey that began in Kuala Kubu Bharu. The water that was originally clean got dirty as a result of human growth. The results of human behavior eventually return to themselves when the source of polluted water will be presented in their food supplies and the effects will return to them.
