Many modern medicines are derived from compounds found in plants within rainforests, highlighting the importance of conservation.

A mature tree is estimated to produce enough oxygen to support multiple people annually through photosynthesis.

While the Amazon is vital for carbon sequestration, its contribution to global oxygen production is often estimated at around 20%.

Marine plants, specifically phytoplankton, are responsible for producing more than half of the oxygen in the atmosphere.

Plastic bottles are not biodegradable and take hundreds of years to break down in landfill conditions.

Glass is inert and does not decompose in the traditional sense, taking up to a million years to break down.

Glass bottles take significantly longer to break down than paper, plastic, or diapers, often lasting up to a million years.

The vast majority of Earth's fresh water is locked in ice caps and glaciers, accounting for approximately 70% of the fresh water supply.

Only a very small fraction of Earth's total water is fresh water; the rest is saline water in the oceans.
