Green happiness

When I was a child, my grandparents always told me that when they were young, the sky was blue, the water was clear and there was a deep intoxicating sweetness. From time to time, there were birds that made a crisp and sweet tweet, very quiet. I think they are very happy.
The day is always gray. Listening to the teacher, it is because with the progress of social industrialization, people enjoy a lot of factories and machinery, while emitting a lot of harmful gases such as sulfur dioxide and nitrogen oxides while enjoying social efficiency. As well as dust, they constantly absorb oxygen to produce acid rain and ozone. The ozone layer is reduced, and various rays in the sunlight directly illuminate the human skin, causing many people to develop various skin diseases.
Many of the electricity is still generated by thermal power. When they generate electricity again, they will generate a lot of dust, which will greatly damage the atmosphere. The exhaustion of a large number of cars also greatly affects the environment.
Because the atmosphere is polluted and the ozone layer is destroyed, the Earth's temperature is warming, resulting in a greenhouse effect, which has caused the Arctic Ocean and Antarctica, including the Kilimanjaro and the Himalayas, to melt. The sea level is rising and the continent is getting more and more harmful. Now the Americas, Europe and Asia Pacific are suffering from different levels of flooding.
It is the bad consequences caused by the constant changes in the environment.
The deterioration of the environment has caused a large number of animals to lose their homes. The balance of nature has been broken, the biological chain has been destroyed, more and more animals and plants have been reduced or even destroyed. So, our environment is getting worse and worse, let us The life is full of haze, losing the fragrance of birds and flowers.
Fortunately, more and more people of insight recognize the importance of the environment and propose improvements one after another, such as waste utilization, bio-power generation, increased green plant coverage, reduced soil erosion, prevention of desertification, and reduction of vehicle exhaust. Rational use of energy.
When, I can also have enviable happiness like my grandparents. For this goal, I will work hard with many people with lofty ideals to build the home we yearn for and let our happiness come sooner.
