Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
Which of your activities affect biodiversity?
The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines and timber which drives around 20%.
What are 5 things that affect biodiversity?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.

What causes threats to biodiversity?
The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. … Habitat loss occurs through deforestation, damming of rivers, and other activities.
What causes biodiversity?
The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.
What are two specific human activities that result in a loss of biodiversity?
The main human activity that affect biodiversity are habitat destruction, foreigner species importation and hunting.
What human activity would have the largest negative effect on biodiversity?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
How do economic development and human activities affect biodiversity?
As human activities encroach upon the natural world, through deforestation and urbanisation, we reduce the size and number of ecosystems. As a result, animals live in closer quarters with one another and with humans, creating ideal conditions for the spread of zoonotic diseases.
What is the greatest impact on biodiversity caused by agriculture?
Industrial agriculture also wreaks havoc on biodiversity within soil. Communities of insects and other invertebrates have their habitats disturbed when farmers plow up soil, interrupting their ability to recycle dead plants into the rich, stable organic carbon that makes soils fertile.
What are three human activities that have negatively affected biodiversity in Gorongosa National Park?
Diverse human activities negatively affect biodiversity to varying degrees. These activities range from hunting and trapping animals to large-scale warfare, from selective logging to clearing forests for agriculture, from diverting streams to damming large rivers, and from point source pollution to climate change.
