Topic 1 life on earth
Conditions for life on earth:
Position of the earth, it's size, structure, composition and rotation= PSSCR!
These have combined to produce the conditions that allowed life to develop on earth.
Large amounts of liquid water:
Temperature control e.g evaporation of water from skin cools body down.
Environmental science topic 2-
Why should we conserve?
Knowledge and understanding- we can learn a lot from studying wildlife
Human behaviour- studying groups of animals e.g apes we learn social structures and group behaviour.
Interdependence of life on earth- our survival depends on the survival of other species.
Biomimetics- Is the knowledge of how other species are adapted to survive and the application of that to solve human engineering problems.
Aesthetics and recreation- a world with plants and animals is more pleasant to live in
Morals- people believe other organisms have the right to life
Ethics- it is not ethically right to exploit wildlife
Economic reasons- can get money e.g zoos
Medical benefits- physiological research
Food resources- few species are currently exploited for food, more available.
