all Lives on Earth​

Answer 1

Geneva, 19 November 2019:  The Secretariat of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) announced today the theme of United Nations World Wildlife Day 2020: “Sustaining all life on Earth”.

The year 2020, known as a “biodiversity super year”, will host several major global events that place biodiversity at the forefront of the global sustainable development agenda. It provides a unique opportunity to deliver transformative progress for the conservation and sustainable use of the species of wild animals and plants in response to global sustainable development challenges that can best be addressed with nature-based solutions.

The theme of World Wildlife Day 2020, “Sustaining all life on earth”, encompasses all wild animal and plant species as a component of biodiversity as well as the livelihoods of people, especially those who live closest to the nature. It also underlines the importance of sustainable use of natural resources in support of the achievement of the United Nations Sustainable Development Goals (SDGs) including Goal 14 (Life Below Water), Goal 15 (Life on Land), Goal 1 (No Poverty) and Goal 12 (Ensure sustainable consumption and production patterns).

CITES Secretary-General Ivonne Higuero said: “Wildlife, namely the species of both wild animals and plants for the purpose of World Wildlife Day, is an integral part of the world’s biological diversity which has the greatest resonance with the general public. In the run-up to and on World Wildlife Day 2020 we will raise awareness of the multitude of benefits of wildlife to people, the interlinkages between the various components of biodiversity and the threats they are facing. It is also a good opportunity to call on governments around the world, civil society, private sector and individuals to add their voices and take actions to help conserve wildlife and ensure sustainable use before it’s too late”.

Answer 2

The existence of diverse definitions of life, as detailed in the previous section, surely means that life is complex and difficult to briefly define. A scientific understanding of living systems has existed since the second half of the 19th century. But the diversity of definitions and lack of consensus among professionals suggest something else as well. As detailed in this section, all organisms on Earth are extremely closely related, despite superficial differences. The fundamental pattern, both in form and in matter, of all life on Earth is essentially identical. Also, as noted in this section, this identity implies that all organisms on Earth are evolved from a single instance of the origin of life. To generalize from a single example is difficult, especially when the example itself is changing, growing, and evolving. In this respect the biologist is fundamentally handicapped, as compared with, say, the chemist, physicist, geologist, or meteorologist, each of whom can now study aspects of his discipline beyond Earth. If truly only one sort of life on Earth exists, then perspective is lacking in a most fundamental way. On the other hand, the historical continuity of all life-forms means that ancient life, perhaps even the origins of life, may be glimpsed by studying modern cells.
