Agricultural experts say crop diversity is important to feed the increasing population of our planet. They say having a large variety of plants also helps to protect against possible crop diseases and future crises. Hundreds of thousands of different plants now exist. But many experts say the number has decreased sharply during the past century.
One of the world’s largest seed conservation projects has predicted further losses. (3) The Millennium Seed Bank Partnership is warning that up to 100,000 plant species could permanently disappear. The rich collection of genes that decide their qualities would disappear with them. (4) Many experts blame climate change and loss of habitat, normal growth area, for damaging plant life. They say human activities and poorly planned, overly heavy use of land are also responsible.
The United Nations Food and Agriculture Organization says modern business farming is responsible for the loss of farmers’ traditional crop varieties. The "Green Revolution" of the 20th century changed agriculture. As a result, some traditional crops were lost.
