Do You Know What is The Problem Above Our Heads?
In this era, we know about a serious global problem which is called ozone depletion. Do you know something about ozone? Ozone is a combine molecule from single oxygen atom and oxygen O2. The ozone layer is a region of a high ozone concentration in the stratosphere layer and acts as an invisible shield. Long-term exposure to high levels of UV-B can severely damage most animals, plants and microbes, so the ozone layer protects all life on Earth.
But, as we know, the ozone layer is getting thinner. Reduced ozone levels as a result of ozone depletion means less protection from the sun’s ray and more exposure to UV-B radiation at the Earth’s surface. This ozone depletion also brings impact to our life. It gives many effects on various sectors. For examples, on human health, plants and marine life. First, on human health. Ozone layer depletion increases the amount of UV-B that reaches the Earth’s surface, significantly increasing the risk on major health issues worldwide, such as skin cancer. Second, on plants. UV-B radiation affects the physiological and developmental processes of plants. Ozone depletion affects the basic processes of plant growth and development and can reduce plant growth. Uncontrolled ozone depletion would have reduced the amount of crop production globally, leaving us all with less food. Third, on marine life. The sun’s UV ray penetrates deep into our oceans. Increased exposure to UV radiation damages algae, crustaceans and fish eggs, the base of the ocean’s food chain. Small increases in UV-B exposure could result in population reductions for small marine organisms with implications for the whole marine food chain.
So what can we do? While scientists and researchers find new solution and create earth-friendly products, there are things we can all do. Such as buying products that are labeled “ozone friendly” or “HCFC free” and taking care of your appliances to minimize ozone layer impact. Also, don’t forget to protect ourselves from ozone layer depletion by taking extra precautions, using sunscreen, wearing a wide-brimmed hat and protective clothing and paying attention to the UV index.
