Agriculture has experienced a great transformation over the last three centuries. Our capacity to produce food from land has significantly improved as we adopted more intensive methods of crop cultivation. At the beginning of the 18th century, the average wheat harvest in England equaled 19 bushels per acre, while a hundred years later it was 30 bushels per acre.
How Can We Prevent or Reverse Desertification and Save Lands from Desert Encroachment?
As other natural ecosystems, deserts have their own dynamics independent of human activities. Throughout the history, sand dunes have always been retreating or slowly expanding into adjacent areas when given the chance. But processes that happen during desertification are different. They do not follow natural patterns. They are more unpredictable and dangerous. They can happen much quicker!
Why Is Recycling Important?
Recycling is more important today than ever before. The amount of waste produced worldwide is estimated to triple by 2025, from 0.68 to 2.2 billion tons per year. The largest producers of waste are, in general, developed countries. Every day, 80 million plastic bottles and 288 million aluminum cans end up in waste in the United States alone.
Find Your Happiness in Nature
Walking in nature makes you more mindful and relaxed, when compared to walking for the same amount of time along city streets. Numerous scientific studies have discovered that residents of the urban areas who have limited possibility to spend time in green spaces are more vulnerable to psychological problems: mood disorders, anxiety, post-traumatic stress disorder, or depression.
