Dryness is an important phenomenon in the natural environment and has a great impact on life, the ecology and other related matters.

Dryness is a natural process that occurs when the temperature decreases and the humidity drops, leading to the decrease of atmospheric moisture. It is characterized by aridity and desiccation. When dryness occurs, the relative humidity of the air goes below 8%, causing the air to turn dry and hot.

In addition to causing dehydration and skin drying, long-term dryness can also damage vegetation. Without sufficient water, plants cannot photosynthesize and cannot absorb enough sunlight to form sustainable life. Over time, the plants may start to lose leaves and branches, the leaves and stems become hard, the leaf color turns yellow and the tips and edges of the leaves curl up. Moreover, the reduction in the number of plants may further reduce the number of other animals who depend on them for survival, further impacting local biopersity.

Dryness can also cause respiratory problems among humans. During a period of dryness, dust particles as well as other pollutants could increase in the air, leading to air pollution. Furthermore, dry air can also lead to dry noses, throats and airways, making it difficult to breath, leading to respiratory diseases.

Finally, prolonged dryness could cause an increase in the probability of forest fires. Trees and weeds are easy to be ignited in dry conditions and any spark could cause the dry stuff to burn and trigger the fire.

Given the impacts of dryness, it is important to take appropriate actions to preserve the natural environment. People should build awareness and promote adequate water conservation measures. Reducing water usage and adopting energy efficiency practices could be very useful. Moreover, people should also reduce air pollution and involve in forest management activities in order to protect the environment and reduce the risk of forest fires.
