1.Explain the importance of the study of past environments in predicting the impact of human activity in present environments.
Situations that occur in today's environment have happened in the past, so a close study of past environments leads to a knowledge of past environments and conditions which allows a better understanding of present-day ecosystems whic helps us to predict the human impact in present environments which leads to harmful practices being recognised and conservation projects.
2.Identify the ways in which palaeontology assists understanding of the factors that may determine distribution of flora and fauna in present and future environments.
FACTORS THAT MAY DETERMINE THE DISTRIBUTION OF FLORA AND FAUNA
Ã¢ÂÂTemperature; hot, cold
Ã¢ÂÂLand masses separating
vChange of landscape
vAbundance of other species
Palaeontology assists the understanding of these factors by providing evidence as to how much of an impact these factors had in past environments, analysis of this evidence allows a moderately accurate prediction of how they will affect present and future environments.
3.Explain the need to maintain biodiversity.
Biodiversity is the sum of all the different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live.
Biodiversity is essential for maintaining the functions of natural systems on Earth.
Without biodiversity there would be;
ÃÂ»no clean water
ÃÂ»no clean air
ÃÂ»no productive soil
ÃÂ»no natural recycling system
Human activities depend on biodiversity
Ã¢ÂÂAgriculture - disease free crops
Ã¢ÂÂForesting - life, density of forests
Ã¢ÂÂFisheries - food, concentration of marine life
Ã¢ÂÂTourism - places for tourists to visit
Ã¢ÂÂConstruction - materials
Ã¢ÂÂTextile manufacturing - materials
Ã¢ÂÂMedicine - lifesaving medicine
