Deforestation is one of the leading threats to our environment, with the world losing around 10 million hectares of forest each year — an area roughly the size of South Korea. Trees play a critical role in absorbing carbon dioxide, producing oxygen, and providing homes for countless species. When forests are cleared for agriculture, logging, or urban development, not only is wildlife displaced, but carbon stored in trees is released back into the atmosphere, worsening climate change. For example, the Amazon Rainforest, often called the “lungs of the Earth,” has lost over 17% of its forest cover in the last 50 years — pushing many species toward extinction and increasing global warming. 

Waste and chemical pollution occur when harmful materials like garbage or toxic substances enter the environment. Common sources include household waste, factory runoff, and agricultural chemicals. These pollutants can contaminate soil and water, harming wildlife and human health. For example, plastic in oceans injures marine animals, while chemical spills poison rivers. If not managed properly, pollution threatens ecosystems, clean water, and food safety. 

Climate change is the long-term warming of Earth’s atmosphere and surface, mainly caused by human activities like burning fossil fuels for transport, electricity, and industry.

This leads to more greenhouse gases, which trap heat and raise global temperatures.

As a result, ice caps are melting and sea levels are rising.

Extreme weather — including floods, heatwaves, and storms — is becoming more frequent.

Some areas are experiencing heat levels that endanger both humans and wildlife.

Wildfires, droughts, and coastal erosion are also on the rise.

To fight this, we must reduce emissions and protect ecosystems.

Switching to clean energy is key to slowing climate change.
