We throw away roughly 500 million tons of garbage in Japan each year, with about a tenth of it coming from homes and offices. It translates to around one kilogram of waste per person every day.

“3Rs” means Reduce, Reuse, and Recycle. It has been popular since it was introduced as the Basic Law for Establishing a Recycling-Based Society in 2000. Today, not only in Japan but in other parts of the world, numerous measures have been taken to pursue a sustainable society.

Let’s take a deeper look at the Edo period. Worn-out clothing was used as floor coverings before being burned to ash. Ashes themselves were utilized as fertilizer, dyes, and detergents, or sold to ash buyers. According to documents, one arithmetic textbook in a temple school was utilized for 109 years. Farmers would pay money or donate crops in exchange for human waste. Recycling had the beneficial impact of producing a variety of occupations. Throughout the Edo period, there was little unemployment.

The population of Japan has increased by a factor of two and a half, but the environment showed little sign of getting any worse. Residents were forced to recycle what they had due to the scarcity of commodities and materials. Everything was viewed as a precious resource. The phrase “mottainai,” or “what a waste,” is still part of our daily lives today.

I visited my friend from Nagaoka, Niigata and we went to a fireworks festival. We dressed up in yukata and tried many foods from the stall. I enjoyed playing the festival games with my friend. We both won many prizes! The festival started with three white fireworks. My friend said, “Many people died in Nagaoka during the war in August 1945.” He added, ” With these fireworks, we remember them and pray for peace.” I didn’t know that. The fireworks touched my heart.

5 percent of the world’s population lives on less than $1.90 a day. Those people are considered to be in extreme poverty. Poverty is caused by a variety of factors, including hunger, a lack of access to clean water, and poor healthcare systems. Various cooperative improvements are needed to resolve poverty.

How many people are suffering from hunger? According to current estimates, about 690 million people, or 8.9 percent of the global population, are hungry. The World Food Program shows that 135 million people are chronically malnourished due to man-made conflict, climate change, and economic drop.

In 2019, 47 million children under the age of five were affected by wasting or acute undernutrition. These conditions make children too thin and weak. They increase the risk of death as well as poor development and learning capacity.

Food and humanitarian aid must be needed in the most vulnerable areas as soon as possible. To avoid a hunger crisis, agricultural productivity and long-term food production must be increased.

Bangladesh is a small country, but it has a large population. The country is struggling to sustain and improve its current food production to feed its rapidly rising population.

Estimates show that Bangladesh will run out of agricultural land by 2080 if the current trend continues. Every year, the country loses approximately 80 thousand hectares of cultivable land due to various activities that affect people’s lives. This will have an impact on its food production.

Additionally, Bangladesh’s agriculture system is still outdated and unscientific. It makes it harder to produce food.

In Bangladesh, population growth is the primary cause of famine.
