PPT-Unit A – Human Activity and Biodiversity

41 Reduction of Biological Diversity Outcomes Describe ongoing changes in biological diversity through extinction and extirpation of native species 41 Reduction of Biological Diversity Species and ecosystems on Earth and the ecological processes of which they are apart are being stressed by urbanization and the expansion of human industries. The complexity and rich diversity of life found in forests provides many vital services to human beings Nonetheless humans are destroying forest biodiversity at an alarming rate The conversion of forests to agricultural land overgrazing unsustainabl What is Biodiversity?. All living things in a food web are connected.. If the numbers of one species are affected it affects the numbers of all other species in the food web.. If the numbers of baboons decreased then this would affect every other living things in the food web.. Sun Simiao. Study Human Activity from Raw GPS Data. Current Condition:. Lots of GPS. . devices provide us . h. uge amount of GPS data. GPS data does not improve semantic richness. Problem:. How to conquer the semantic gap between raw data and personal activity. HUMANS IN THE BIOSPHERE. Humans in the Biosphere. The . biosphere. is the part of the Earth where life exists, including the land, water, and air. .

Microevolution. is evolution on a small scale, and it results in changes in the proportion of genes in a population.. Objectives:.

In the early 20th century, hunting and habitat loss reduced the wild population to just 20–30 animals.. Conservation efforts have helped the wild population rebound to 450–500 today.. Extinction . When an organism is classed as extinct there are no living members of that species left. Extinction is a natural process where organisms that are less suited to an environment die out. Throughout the history of earth there have been several mass extinction events . Prof. Bartosz Wojciechowski, the Center for the . Theory. and . Philosophy. of Human .
