Composition on protecting the environment and protecting the earth

The earth is the environment on which we live and the only planet for human beings and animals to live. But ... our present environment has been destroyed. Those people are ourselves. For example: littering, cutting down trees, over-building factories and houses. Step on the lawn and so on.

In this way, our beautiful planet will be destroyed in our hands. In cities, the river is getting smelly, garbage can be seen everywhere, and even plastic bags are flying all over the sky, polluting the environment. Automobile exhaust is also quietly endangering our environment. If we wantonly destroy the environment again, we will naturally be punished.

Those catastrophic floods claimed countless lives, and due to the greenhouse effect, glaciers in Antarctica and the Arctic melted, resulting in rising water levels and seawater flooding coastal areas, which caused great economic losses. Isn't this the best proof? From now on, let's take action to make our home a beautiful place. At that time, to make our home look brand-new, we still had to plant trees and grass first.

Planting plants containing chlorophyll is of great help to improve air quality. First of all, green plants can carry out photosynthesis in the sun, absorb carbon dioxide and release oxygen. Studies show that plants can produce 5 tons of oxygen per growth 1 ton.

Each hectare of forest can absorb 1 ton of carbon dioxide every day, producing 0. 735 tons of oxygen; Soil and water conservation, climate regulation, wind and sand fixation and other functions. Each hectare of grassland can absorb 0.9 tons of carbon dioxide and produce 0.6 tons of oxygen every day. About 3 tons of dust falls on a hectare of ground in a city every year, and trees and grasslands have strong adhesion to dust.

On the street with better greening, the distance from the ground is 1. The dust content of 5 meters is about 60% lower than that of the area without greening. The dust in urban streets is generally more than that in green spaces 1/3 to 1/2. Trees and grasslands can weaken the noise intensity and reduce its harm. Compared with non-green streets, green streets can reduce noise by 8 decibels to 10 decibels; The 20-meter-wide grassland is reduced by about 2 decibels.

Adequate and clean oxygen can keep people healthy. Now, the ecological environment of the earth is getting worse and worse, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a bright future in which man and nature live in harmony, and let man and nature live endlessly.
