Environmental change involves various components, including:

1. **Climate Change:** Alterations in temperature, precipitation patterns, and weather conditions over an extended period.

2. **Biodiversity Loss:** Decline in the variety and abundance of plant and animal species within ecosystems.

3. **Land Use Change:** Transformation of landscapes due to factors like urbanization, deforestation, and agricultural expansion.

4. **Pollution:** Introduction of harmful substances into air, water, or soil, negatively impacting the environment and living organisms.

5. **Natural Disasters:** Events such as hurricanes, earthquakes, floods, and wildfires that can have profound and immediate effects on the environment.

6. **Resource Depletion:** Overuse or exhaustion of natural resources like water, soil, minerals, and fossil fuels.

7. **Ocean Acidification:** Increased acidity in the oceans, primarily caused by the absorption of excess carbon dioxide from the atmosphere.

8. **Habitat Destruction:** Disruption or elimination of habitats essential for various species, often linked to human activities.

Addressing these components is crucial for sustainable environmental management.

However, it was in the 20th century that their significance became clear. In the 1960s, scientists like Albert Claude and Christian de Duve contributed to understanding their role in cellular respiration. Today, mitochondria are recognized as essential organelles for energy production and have their own genetic material.
