LOREN LEGARDA: BUHOS, A Climate Change Documentary FULL

Summary

The documentary explains that human life, livelihoods, and well-being depend on Earth’s natural resources. It presents climate change and global warming as consequences of human activities that intensify the natural greenhouse effect.

Sunlight reaches Earth, where some energy is absorbed by land, plants, and water, while some is reflected back toward space. Greenhouse gases naturally retain some of this heat, keeping Earth warm enough to support life. The film explains that emissions from activities such as burning gasoline, industrial production, and excessive electricity use add to these gases, trapping more heat and raising atmospheric temperatures.

The documentary describes several consequences of warming and changing climate patterns:

• Rising sea levels can threaten coastal land and homes, and harm wildlife such as polar bears.
• Changes to seasonal patterns, including El Niño, can disrupt farming and reduce food supplies.
• Higher temperatures can worsen heat-related illnesses and may contribute to the spread of disease-carrying insects associated with dengue and malaria.
• Heavier or prolonged rainfall and typhoons can cause flooding, which can be made worse when garbage blocks waterways.
• Loss of land and damage to ecosystems can affect people, animals, and future generations.

Suggested Actions

The film recommends individual, community, and government efforts:

• Plant trees, which absorb carbon dioxide and release oxygen.
• Avoid wasteful consumption and replacing usable goods unnecessarily.
• Save electricity by switching off appliances when they are not in use and limiting decorative lighting.
• Reduce gasoline use by walking for nearby trips or sharing rides.
• Reuse and recycle items to reduce production, pollution, and resource use.
• Share information about climate change with family, colleagues, and friends.
• Support environmental measures, including efforts to prevent illegal logging and deforestation, as well as government action at national and local levels.

Researchers and Sources Featured
