Planting trees not only greens and beautifies our homes, but also expands forest resources, prevents soil erosion, protects farmland, regulates climate, and promotes economic development. It is a great project benefiting the present generation and future generations. To protect forestry resources, improve the environment, and maintain ecological balance, many countries around the world have established Tree Planting Days according to their own situations. For example, India has its Tree Planting Day in the first week of July; North Korea's Tree Planting Day is on March 2nd; Thailand has its National Day as its Tree Planting Day; the Philippines has its Tree Planting Day on the second Saturday of September; Italy has its Tree Planting Day on January 21st; the United States has Tree Planting Days in each state, but due to differences in climate, there is no unified date nationwide; Brazil has its Tree Planting Day on September 21st; Colombia has its Tree Planting Day on October 12th; El Salvador combines its Tree Planting Day with Teacher's Day, which is held on June 21st every year; Egypt has its Tree Planting Day from September to November...

Among these countries, the United States has the oldest Tree Planting Day, with a history of more than 130 years. On April 10, 1872, the first Tree Planting Day in the United States was initiated by a journalist from Nebraska. On that day, over one million trees were planted throughout the state of Nebraska.

Brazil is a country with extremely rich forest resources, with nearly three-fifths of the world's largest tropical rainforest, the Amazon, located within its borders. The national forest coverage rate is more than 52%. Despite this, the Brazilians still do not forget to plant trees. The Brazilian government, while rationally developing forest resources, actively encourages people to plant trees.

In response to the threat of global warming, the United Nations Environment Programme launched the "10 Billion Trees Campaign" on November 8, 2006, in Nairobi. This campaign plans to plant at least 1 billion trees worldwide in 2007.

As people's environmental awareness continues to increase and they actively participate in tree planting activities, the environment in which we live will be constantly improved.

According to the United Nations, currently, more than 50 countries have established Tree Planting Days. Due to different national conditions and geographical locations, the names and dates of Tree Planting Days vary across countries. For example, Japan calls it "Tree Day" and "Greening Week"; Israel calls it "New Year of Trees"; Myanmar calls it "Tree Planting Month"; Yugoslavia calls it "Tree Planting Week"; Iceland calls it "Student Tree Planting Day"; India calls it "National Tree Planting Day"; France calls it "National Tree Day"; Canada calls it "Forest Week".

Spain's Tree Planting Day is on February 1st;

Iraq's Tree Planting Day is on March 6th;
