Care for the Earth

The Earth needs to be cared for.

Biodegradable materials are objects that easily decay like fruit peel and paper. These can be used as compost or fertilizer for the soil and as fuel.

Nonbiodegradable materials are objects that do not easily decay even after a hundred of years. Some of the wastes here can be recycled, processed and/or reused like old bottles made into new glass containers.

To keep the soil fertile, plant seedlings. Plant roots help hold the soil together by preventing the top part of the soil from being washed away. Adding compost, a mixture of decaying matter like fruit peels and decaying leaves is another way to make the soil fertile.

The water and the air are also important in the environment.

Waste pollutes water like rivers and streams.

By not burning waste, especially plastic that is poisonous when inhaled, would help curtail serious health problems.
