The Earth seen from Apollo 17. The first International Day for Biological Diversity was celebrated 28 years after the mission. The International Day for Biological Diversity (or World Biodiversity Day) is a United Nations –sanctioned international day for the promotion of biodiversity issues. It is currently held on May 22.
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species [1] that ever lived on Earth are estimated to be extinct. [2][3] Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around 11 ...
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Beyond the value biodiversity has in regulating and stabilizing ecosystem processes, there are direct economic consequences of losing diversity in certain ecosystems and in the world as a whole. Losing species means losing potential foods, medicines, industrial products, and tourism, all of which have a direct economic effect on peoples lives. [6]
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5][6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage.
Habitats are being destroyed daily without considering the damage done to biodiversity on both micro and macro levels.
Biodiversity (or biological diversity) is the variety and variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. [ 1 ] Diversity is not distributed evenly on Earth.
Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land".One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss".
