Know the signs. Protect our air and water.

Through indicators like AQI, ozone, carbon monoxide, pH, and turbidity, we can measure how healthy our environment is.
With the Clean Air Act and Clean Water Act, we work toward safer air and cleaner water for all Filipinos.

🔬🍅 Way back in the 1940s, during World War II, there was a shortage of tomatoes in the Philippines. Filipina technologist, food chemist, pharmacist, and war heroine 𝑀𝑎𝑟𝑖𝑎 𝑌. 𝑂𝑟𝑜𝑠𝑎 came up with a brilliant solution! Using an abundant local fruit—saba bananas—she experimented and created a sweet, tangy, and distinctly Filipino condiment that we all know and love today as banana ketchup!

From our kitchen staple to her other inventions like Soyalac and Darak, Orosa showed us how science can be seasoned with creativity and love for our own. She didn't just invent a sauce, she invented a taste of Filipino ingenuity. 🇵🇭✨

Food Additives 🧪🍴

Have you ever wondered why some foods stay fresh longer, taste better, or have appealing colors? 👀✨ Food additives are substances intentionally added to food to improve its taste, texture, appearance, freshness, or shelf life.

Common examples include preservatives, flavor enhancers, food colorings, sweeteners, and emulsifiers. 🧂🍬🎨 These additives help maintain the quality and safety of many foods we enjoy every day.

Food additives play an important role in modern food production. However, understanding what we consume and reading food labels can help us make more informed choices about the food we eat. 🔍🥫

Golden Rice 🌾

The Golden Rice is created by german scientists Ingo Potrykus and Peter Beyer in late 1990s. They bypassed this barrier by inserting genes from maize (corn) and a common soil bacterium (Pantoea ananatis) into the rice's DNA. 🪎🌾

It's a variety of price that has been genetically engineered to produce beta-carotene, a pigment that the human body converts into Vitamin A. The main reason why the Golden Rice is created is
to address Vitamin A Deficiency (VAD) in developing nations where white rice is the main food source.

Golden Rice has become one of the most important case studies for the future of agricultural biotechnology. Unlike many commercially engineered crops controlled by major corporations, Golden Rice was built as a public good.

💧🌎 THE WATER CYCLE: NATURE’S NEVER-ENDING JOURNEY ☁️🌧️
Water is always moving around our planet in a continuous process called the water cycle! 💦 From the oceans, lakes, and rivers, water is heated by the Sun and changes into water v***r through ev***ration. 🌞💨 Plants also release water v***r through transpiration. As the water v***r rises and cools, it turns into tiny droplets and forms clouds through condensation. ☁️✨ When the clouds become heavy, water falls back to Earth as precipitation, such as rain. 🌧️ The water then flows into rivers, lakes, oceans, or soaks into the ground through collection and infiltration, beginning the cycle all over again. 🌊🌱
The water cycle reminds us that water is constantly recycled by nature and is essential for every living thing. 💙🌍💧
