Takeaways

• 😀 Environmental diseases are caused by the interaction between humans and their surroundings, which can lead to various health issues.
• 😀 Clean water is essential for health. Safe drinking water must meet physical, microbiological, chemical, and radioactive standards.
• 😀 Waste management is crucial. Improperly managed waste, especially plastics, can cause environmental damage and health risks.
• 😀 Global warming is a result of human activity, such as the emission of greenhouse gases, which trap heat in the Earth's atmosphere.
• 😀 To combat global warming, actions like planting trees, using public transport, cycling, and recycling are recommended.
• 😀 Energy crisis refers to the shortage of energy sources, especially fossil fuels, which are non-renewable and contribute to environmental damage.
• 😀 Alternative energy sources, like solar, wind, geothermal, and biofuels, offer eco-friendly solutions to the energy crisis.
• 😀 Indonesia faces food security issues due to low food availability, and the country needs to improve agricultural productivity.
• 😀 To increase food availability, strategies like intensifying agriculture (better seeds, fertilizers, and methods) and expanding farming areas are essential.
• 😀 Addressing environmental challenges requires awareness, education, and collective efforts to ensure a sustainable future.

Q & A

What are environmental-based diseases?

Environmental-based diseases are health conditions caused by the interaction between humans and their surrounding environment, which contains potential disease-causing factors. These diseases include conditions like influenza, respiratory infections, and dengue fever.

What factors contribute to the occurrence of environmental-based diseases?

The factors contributing to environmental-based diseases include the availability of clean water, sanitation, waste management, lifestyle habits, and the presence of disease vectors.

What defines safe drinking water according to the Health Minister's Regulation No. 492 of 2010?

Safe drinking water is defined as water that meets physical, microbiological, chemical, and radioactive standards. Physically, it should be odorless, tasteless, and clear. Biologically, it should not contain harmful microbes, chemically it should be free from dangerous substances, and radioactively it should not exceed certain limits.

What are some common sources of safe drinking water?

Common sources of safe drinking water include well water, boreholes, public taps, terminal wells, and rainwater storage systems.

What impact does improper waste management have on the environment?

Improper waste management can lead to numerous problems, including visual pollution, health hazards, disruption of ecosystems, and even disasters. It is important to manage waste properly to prevent these negative effects.

Why is plastic waste a major environmental concern in Indonesia?

Plastic waste is a major concern because it is not biodegradable and can accumulate in the environment. Many people discard plastic waste improperly, leading to pollution of drains, rivers, and oceans, contributing to Indonesia's plastic waste crisis.

What is global warming, and how does human activity contribute to it?

Global warming refers to the gradual increase in Earth's average temperature. It is mainly caused by human activities that release gases like carbon dioxide, methane, and nitrogen oxides into the atmosphere, trapping heat and preventing it from escaping into space.

What are some consequences of global warming?

Consequences of global warming include rising sea levels due to melting ice caps, prolonged droughts, extreme weather conditions, and increased natural disasters.

What actions can be taken to mitigate global warming?

To mitigate global warming, individuals and societies can plant trees, use public transportation, cycle, recycle waste, and reduce carbon emissions from industrial activities.

What is energy crisis, and what causes it in Indonesia?

An energy crisis refers to a shortage of energy resources, which can disrupt daily life and economic activities. In Indonesia, the crisis is driven by a heavy reliance on non-renewable fossil fuels like oil and coal, which are finite and depleting.

What are alternative energy sources, and how do they benefit the environment?

Alternative energy sources include solar, wind, hydro, geothermal, biogas, bioethanol, and nuclear energy. These sources are environmentally friendly as they produce fewer greenhouse gas emissions compared to fossil fuels.

How can food security be improved in Indonesia?

Food security in Indonesia can be improved by increasing agricultural production through intensification (improving crop quality and farming techniques) and extensification (expanding agricultural land).
