Explanation
Less than 1% of the world's water is available for human use. This is due to the majority of water being in the form of saltwater in oceans and seas, which is not suitable for drinking or irrigation. Only a small fraction of freshwater is easily accessible in lakes, rivers, and underground sources. With the growing population and increasing water demands, it is crucial to conserve and manage this limited resource effectively.

Explanation
Recycled plastic bottles can be transformed into various products such as clothing, carpets, detergent bottles, and lumber for outdoor decking. By recycling plastic bottles, they can be given a new life and repurposed into different items. The plastic can be melted down and spun into fibers to create clothing or used to make carpets. It can also be processed to produce new detergent bottles or be transformed into lumber for outdoor decking, providing a sustainable alternative to traditional materials.

Explanation
One bus can carry as many people as 40 cars because buses have a larger seating capacity compared to cars. Buses are designed to transport a large number of passengers at once, typically seating around 40 to 60 people depending on the size of the bus. On the other hand, cars usually have a seating capacity of 4 to 5 people. Therefore, the number of people that can be transported in one bus is equivalent to the number of people that can be transported in 40 cars.

Explanation
Trees renew our air supply by absorbing carbon dioxide and producing oxygen. This is true because trees undergo the process of photosynthesis, where they take in carbon dioxide and release oxygen. Shade trees can make buildings up to 20 degrees cooler in the summer. This is true because trees provide shade and reduce the amount of direct sunlight and heat that reaches buildings. Tree roots stabilize soil and prevent erosion. This is true because tree roots help anchor the soil, preventing it from being washed away by water or wind.
