12. Photosynthesis
Photosynthesis occurs in green plants; to be specific it occurs
in green leaves. The word photosynthesis means putting
together with light. Green plants use energy from light to
combine carbon dioxide and water to make sugar and other
chemical compounds which is needed by the consumer.
Animals and men are their consumers.
The light is absorbed by a green pigment called
chlorophyll of the leaves. Each food-making cell in a leaf
contains chlorophyll in small bodies called chloroplasts. In
chloroplasts, light energy causes water to be drawn from the
soil, to split into hydrogen and oxygen.

Afterwards, the hydrogen combines with carbon dioxide from
the air, forming a simple sugar. Oxygen from the water
molecules is given off in the process. From the sugar—together
with nitrogen, sulphur, and phosphorus from the soil—green
plants can make starch, fat, protein, vitamins and other complex
compounds which are valuable for human life.

17. Use Glass Whenever Possible
Storing your food in glass is an eco-friendly
and healthier alternative to plastic. Plastics
contain harmful chemicals which leach into
our bodies, our water supplies, and the soil.
There are huge islands of plastic floating
around both the Pacific and Atlantic oceans.
The Great Pacific Garbage Patch, composed
of plastics, chemical sludge, and other
debris has grown to be twice the size of
Texas!
