IntroductionSustainable environmental practices are important to support smart growth. As humans, the environment “Earth” is our home. This is where we live, breathe, eat, raise our children, etc. Our entire life system depends on the well-being of all species living on earth. In other words, it is the biosphere where all living things are interdependent on each other. Unfortunately, the planet is in danger, environmental deterioration threatens our planet's natural resources and many animal and plant species are on the verge of being singled out while most of them are non-renewable resources. Therefore, as a responsible human being, the challenge is to take drastic action so that we can make a difference in our lifetime to save our home.Toxic tides: risks of harmful microalgaeThis article was written on the urgency to monitor our local coastal waters. harmful algal blooms (HAB). HAB or red tide, also called water discoloration, occurs when the presence of a sudden population of a toxic-producing microalgae is caused by water enrichment. This not only involved painting the water red, but in some cases it made it cloudy, brown, or foamy. This phenomenon, also known as eutrophication, is due to the process by which a body of water becomes enriched with dissolved nutrients (phosphate, nitrogen, etc.) which can stimulate the growth of aquatic plant life, thereby usually results in the depletion of dissolved oxygen necessary for life. Among the severely affected areas is Sabah, where a mass die-off of marine life was first reported in 1976. At least in early 2013, 40 civilians poisoned from eating contaminated shellfish were reported in Sepaggar and Inanam, near Kota Kinab. ..... middle of paper ...... the soil being charged with electrons by microbial activity but will not discharge. Reversible electrochemical processes can help prevent the release of a massive amount of methane. ConclusionUntil recently, the environmental issue has been largely ignored in conventional economic analysis and decision-making, the main focus of which has usually been profit-oriented. maximization. Countries disagreeing about the nature and extent of threats to the environment and how to address those threats, with scientific, cultural and economic considerations all playing a role in these disagreements. However, it is everyone's responsibility to protect our environment. Let us fulfill our responsibilities in environmental protection, creating a quality ecological environment and sharing a wonderful green life together..
