Unfortunately, while many species depend on the ocean for its ability to create food and oxygen, human activities can negatively impact the ocean and its wildlife. 2. Ecosystems are dynamic and over time the numbers and densities of species will vary. Human activities like the introduction of invasive species, trading in wildlife, pollution, and engagement in wars are also some of the leading factors that have caused the loss of habitat. • Human activities are placing pressures on biodiversity and in many instances leading to losses in diversity. (1 pt each) a. Ø Viral epidemics in animals is major threat to biodiversity. The impact of agricultural activities on biodiversity of plants and animals has a long history, which began when humans first started the domestication process over 7000 years ago (Solbrig and Solbrig, 1994). 2. Ø Animals in captivity are also prone to diseases The most biodeverse ecosystem is a tropical rainforest.
Likewise, the destruction of habitat involves the ocean and marine zones – along with industrialization, urbanization, and tourism are all affecting habitats in our coastal areas around the world. Ø Introduced species may carries pathogens along with them. Ø Human activities sometimes speedup the severity of natural diseases. This is natural change. Human activity #2: Cutting down trees. Ø Animals are more prone to disease than plants. In the contemporary world, human activities may be the most important influence on forests’ capacity to maintain their original biodiversity. List three human activities that have negatively affected biodiversity in Gorongosa National Park and briefly describe how they have affected the park. b. Such activities as commercial and artisanal logging, large scale land conversion, fuelwood and charcoal production, slash and burn agriculture, harvesting of non-timber forest products, hunting and mining all affect forest biodiversity. Species will be lost and new species will evolve. Habitat loss- occurs when human activities result in conversion of natural ecosystem to humandominated systems. Massive habitat loss from land clearing for farming, mining, housing transport corridors and logging. The seven factors that affect biodiversity: 1. Biodiversity fluctuation is natural. Human activity #1: Poaching Effect on the park: The animals will begin to disappear and the mountain, known for their biodiversity, will no longer have these animals to see. Human activities like changing land use, deforestation and peat bog destruction reduce this.
Oceans provide a home for hundreds of thousands of species on Earth, and it is essential for human life. Biodiversity is a measure of how many different species live in an ecosystem.
