    3. Depends on: - number of species and abundance of each species in an ecosystem Growth of population depends on: - Abiotic factors - Biotic factors Index of Diversity: d = N(N-1)/Sn(n-1) d: index of diversity N: total number of organisms of all species in area n: total number of organisms of each species in area Diversity

    4. Impact of Humans Humans pose a huge threat to lives of animals, plants and their environment Our impact is so great due to: - technologies that change the world so quickly - population increase - consumption of natural resources, and waste

    5. Human Population Growth Humans can adapt to survive in almost all habitats and climates. The human population is increasing rapidly and is threatening the environment The population will eventually be limited by these factors: - food and water supply - disease and pollution - over-crowding - sudden changes in climate
