Key sources of pollution that we need to tackle are:

1. Air Pollution:

   • It causes more than 7 million early deaths every year.
   • The biggest causes are: transportation (24%), industries (26%), and farming (10%).

2. Water Pollution:

   • About 2 billion people don’t have safe drinking water.
   • A big part of water pollution, around 70%, comes from farm runoff.

3. Soil Pollution:

   • One-third of the world's soil is hurt because of pesticides and heavy metals.

Fixing these problems is really important for a healthy future.
